A conservatory supply-and-fit contract is a mixed contract: the installer supplies goods (frames, glazing units, roof panels, doors) and also installs them. Chapter 2 of Part 1 of the Consumer Rights Act 2015 covers the goods, and the separate services rules are covered in this site’s guide to substandard installations. This guide summarises the sections on goods as they appear on legislation.gov.uk. The text carries no nation-specific marking for the sections read, but court routes differ between England and Wales, Scotland and Northern Ireland and are not covered. It is general information, not legal advice.

A goods and installation contract

Section 1 of the Act says Part 1 applies where a trader agrees to supply goods, digital content or services to a consumer under a contract, and that each relevant chapter applies even where a contract also covers something under another chapter, described as a mixed contract. A conservatory order can therefore engage the goods chapter and the services chapter at the same time.

Section 15 deals with goods and installation. Goods do not conform to the contract if installation forms part of the contract, the trader installs them or they are installed under the trader’s responsibility, and they are installed incorrectly. A frame or roof unit that is sound when it leaves the factory but is fitted badly is therefore treated as non-conforming goods.

The terms treated as part of the contract

Section 9 treats every contract to supply goods as including a term that the quality is satisfactory, meaning the standard a reasonable person would consider satisfactory taking account of any description, the price and all other relevant circumstances. Quality includes state and condition and, in appropriate cases, fitness for all purposes for which such goods are usually supplied, appearance and finish, freedom from minor defects, safety and durability.

Section 10 adds a term about fitness for a particular purpose. If the consumer made a purpose known to the trader before the contract was made, the goods must be reasonably fit for it, unless the circumstances show the consumer did not rely, or could not reasonably rely, on the trader’s skill or judgment. Section 11 requires goods supplied by description to match the description, and treats the trader’s information about the main characteristics of the goods as a term of the contract. A change to that information is not effective unless the consumer and trader expressly agree it.

What the consumer can ask for

Under section 19, if goods do not conform because of a breach of sections 9, 10 or 11, the consumer’s rights are the short-term right to reject, the right to repair or replacement, and the right to a price reduction or the final right to reject. If goods do not conform under section 15 (incorrect installation) or because of a breach of requirements stated in the contract, the consumer has the right to repair or replacement and the right to a price reduction or the final right to reject. The short-term right to reject is not listed for those two situations.

Section 22 sets the time limit for the short-term right to reject at the end of 30 days beginning with the first day after ownership has transferred, the goods have been delivered, and, where the contract requires the trader to install the goods, the trader has notified the consumer that the action has been taken. Section 19(14) adds that goods which do not conform at any time within six months of delivery must be taken not to have conformed on that day, subject to the exceptions in section 19(15).

Repair, replacement and price reduction

Under section 23, if the consumer requires repair or replacement, the trader must do so within a reasonable time and without significant inconvenience to the consumer, and bear the necessary costs, including labour and materials. The consumer cannot require a remedy that is impossible or disproportionate compared to the other. Section 23(6) provides that a consumer who requires or agrees to a repair cannot require replacement, or exercise the short-term right to reject, without giving the trader a reasonable time to repair, unless that would cause significant inconvenience.

Section 24 sets out the right to a price reduction, which may where appropriate be the full price, and it provides that a consumer with both that right and the final right to reject may exercise only one. Section 19(9) adds that the chapter does not prevent a consumer seeking other remedies, though not so as to recover twice for the same loss.

Practical steps for a homeowner

A homeowner can keep the order form, specification and brochure, because section 11 makes the trader’s description of the goods’ main characteristics part of the contract. Where the fault is fitting rather than the goods, the services rules apply as well. If a resolution route is needed, the guide to resolving a dispute without court covers consumer codes and ombudsman schemes.

FAQs

Does the 30-day short-term right to reject apply to a badly fitted conservatory?

Section 19 lists the short-term right to reject for breaches of sections 9, 10 and 11, but not for incorrect installation under section 15, where repair or replacement and price reduction or final rejection are listed.

Does the six-month presumption apply?

Section 19(14) treats goods that do not conform within six months of delivery as non-conforming on delivery, subject to the exceptions in section 19(15).

Is a conservatory a goods contract or a services contract?

Section 1 says a contract can be a mixed contract, so both the goods and services chapters can apply to the same conservatory order.

The bottom line

The Consumer Rights Act 2015 treats a conservatory supply-and-fit contract as a mixed contract, so the goods rules apply alongside the services rules. Satisfactory quality, fitness for a purpose made known and matching the description are treated as terms of the contract, and incorrect installation makes the goods non-conforming. The remedies and time limits in sections 19 to 24 depend on which term was breached.

A conservatory base means excavation, plant and sometimes lighting close to the garden boundary, and a sett in a hedge bank or under a shed can be affected. This guide sets out the Protection of Badgers Act 1992, which extends to England, Wales and Scotland, and two Natural England pages that apply to England only. Scotland and Wales have their own licensing bodies and guidance, which are not covered here. It is general information, not ecological or legal advice.

What the Act protects

Section 3 of the Protection of Badgers Act 1992 makes it an offence to interfere with a badger sett by damaging it or any part of it, destroying it, obstructing access to or any entrance of it, causing a dog to enter it, or disturbing a badger when it is occupying it. The offence requires an intention to do one of those things, or recklessness about whether the actions would have those consequences. A person who knowingly causes or permits such an act is also guilty of an offence.

Natural England’s guidance for England describes badgers and their setts, the tunnels and chambers where they live, as protected by law. It says a person found guilty of intentionally capturing, killing or injuring a badger, damaging, destroying or blocking access to a sett, or disturbing badgers in a sett could be sent to prison for up to 6 months and receive an unlimited fine.

Groundwork that can affect a sett

The same guidance lists activities that can harm badgers, and several are ordinary parts of a building project: noise, additional lighting or vibration, pile driving, lighting fires, using chemicals, excavation and tree felling. A conservatory plot next to a wooded boundary or an embankment is therefore a place where these checks are worth making before the digger arrives.

Natural England’s standing advice for planning decisions adds that badgers could be affected by damage to setts, loss or isolation of setts, loss of foraging areas and disturbance while they are occupying setts from noise, lights, vibration, fires or chemical use. That advice is aimed at local planning authorities, but it shows what an authority may look for in an application where badgers are known to be present. It also says the absence of a record does not mean there are no badgers, because it may only mean no survey data exists for that location.

When a licence may be needed

The England guidance says that in most cases badgers and setts should be avoidable, and that a person who cannot avoid disturbing badgers in a sett, or damaging or blocking a sett, can apply to Natural England for a licence. Applicants must show they have tried everything else possible, and expert help is needed for a licence application connected to a development project. The standing advice says a developer may need a licence before starting work if they exclude a badger from a sett, disturb a badger, or damage or remove a sett.

The guidance also says a licence is usually not needed for work with hand tools or machinery above or below ground near a sett, or for clearing vegetation near setts, provided it is unlikely to disturb a badger in its sett or damage the sett and small trees or shrubs are not uprooted or used to block access. Natural England will consider the existing level of disturbance around a sett when deciding if a licence is needed. Whether a proposed job falls within these limits is a judgement for a qualified ecologist, not the homeowner.

Avoidance measures the advice lists

For larger projects the standing advice lists measures a proposal could include: keeping heavy machinery and excavation work away from setts, avoiding artificial lighting around setts, retaining vegetation around setts to provide cover, avoiding noise and vibration near active setts, and avoiding activity between dusk and dawn when badgers are most active. It also says mitigation should not include moving badgers off a site (translocation), because that could risk the spread of bovine tuberculosis or affect the badger’s welfare.

Where surveys are asked for, the standing advice says they should identify whether badgers use the site and the surrounding area, and where setts are and of what type, and that they should be kept confidential to avoid ill-treatment of badgers. It also advises checking that the ecologist is qualified and experienced in badger surveys.

What to ask before groundwork

A homeowner who suspects a sett can ask the installer to pause and can seek a qualified ecologist’s view. The installer’s survey and contract steps are covered in the guide to choosing a conservatory installer, and the guide to bats and other protected species covers a separate species and licensing regime.

FAQs

Can I fill in a hole I think is a badger sett?

Blocking access to a sett is an offence under section 3 of the 1992 Act if done intentionally or recklessly, so an ecologist should confirm what a hole is before anything is done to it.

Does the Natural England advice apply in Scotland or Wales?

The two Natural England pages apply to England. The 1992 Act itself extends to England, Wales and Scotland.

Do I need a licence to dig a shallow trench near a sett?

The England guidance says a licence is usually not needed for hand tools or machinery near a sett if disturbance or damage is unlikely, but that is a judgement for a qualified ecologist.

The bottom line

Badgers and their setts are protected by the Protection of Badgers Act 1992, and building groundwork such as excavation, noise, light and vibration can disturb them. In England, Natural England can licence unavoidable interference, and its guidance points to expert surveys and avoidance measures. A homeowner who suspects a sett near a conservatory site should raise it before work starts.

Digging a conservatory base disturbs the ground, and disturbed knotweed rhizome can regrow. This guide sets out what GOV.UK guidance for England says about Japanese knotweed on land and in soil, and how section 14 of the Wildlife and Countryside Act 1981 applies in England and Wales. Scotland and Northern Ireland have separate guidance and, for Scotland, a differently worded section 14. This is general information, not legal or technical advice.

Where the law stands on a garden with knotweed

The Environment Agency, Defra and Natural England guidance for England says a landowner does not legally have to remove Japanese knotweed from their land unless it is causing a nuisance, but they must stop it spreading off the property and can be prosecuted for causing it to spread into the wild. The same guidance notes that soil or plant material contaminated with non-native invasive plants can cause ecological damage and may be classified as controlled waste.

The offence sits in section 14 of the Wildlife and Countryside Act 1981. In England and Wales, section 14(2) makes it an offence for a person to plant, or otherwise cause to grow in the wild, any plant included in Part II of Schedule 9 to the Act. Section 14(3) provides a defence for a person who took all reasonable steps and exercised all due diligence to avoid committing the offence. The Scottish version of section 14 is worded differently, and refers to plants grown in the wild outside their native range.

Why a conservatory project raises the stakes

The GOV.UK guidance explains that knotweed spreads by direct rhizome (root) growth and by new growth from stem and rhizome fragments, and that a new plant can grow from a piece of rhizome as small as 1cm. It also says the rhizome can remain dormant in the soil for many years and will regrow if disturbed or if the soil is relocated. Excavating for footings, drains or a service trench is therefore the kind of activity that can move fragments around a site or off it.

The guidance identifies man-made habitats such as roadsides, waste ground and railway embankments as places where knotweed commonly grows, and it is also found along rivers and streams. It does not say gardens are exempt, so a plot with a stand of knotweed near the planned footprint is a matter to raise before groundwork starts.

Treatment and disposal options on site

The guidance advises against treating knotweed without the appropriate skills and experience, and points to specialist companies. Chemical treatment by spraying or injecting stems can be effective, but only approved herbicides may be used, repeat applications are needed, and it usually takes at least 3 years to treat Japanese knotweed. Depending on the location, a certificate of competence, a Control of Substances Hazardous to Health assessment, Natural England permission for protected areas or Environment Agency agreement near water may be required.

Where knotweed is buried, the Environment Agency must be notified at least one month beforehand. The material must be buried on the site it came from, at a depth of at least 5 metres if no geotextile membrane is used, or at least 2 metres if the material is sealed in a membrane. A membrane must be undamaged, securely sealed, ultraviolet resistant and expected to remain intact for 50 years. Dead brown canes can be composted on site if they are cut, not pulled, at least 10cm above the crown.

For burning, the guidance warns that crowns and rhizomes may survive, so burnt material still needs burial or off-site disposal.

Taking soil away from the site

Where the material cannot be dealt with on site, the guidance says it must go to a landfill site or incineration facility with the correct type of permit, using a registered waste carrier, and the Environment Agency must be told where it was sent. Knotweed waste must not be disposed of with other surplus soil, soil contaminated with knotweed must not be sold as topsoil, and contaminated soil can be reused only after treatment on the site where it grew. A waste licensing exemption cannot be obtained for the use of Japanese knotweed.

These are rules for the person managing the waste, so when a conservatory installer is removing spoil, a homeowner can ask who is responsible and whether they use a registered carrier.

What to ask the installer

Before groundwork, a homeowner can confirm whether the survey looked at the wider garden, whether the installer has a plan for any suspected knotweed, and who will pay for specialist treatment. The wider survey and contract questions are in the guide to choosing a conservatory installer, and ground questions are in the guide to conservatory foundations. The GOV.UK guidance lists accreditations to look for in a specialist contractor: Amenity Forum membership and BASIS registers. It also notes that many such companies belong to the Invasive Non-Native Specialists Association or the Property Care Association.

FAQs

Do I have to remove knotweed before building a conservatory?

The England guidance says there is no legal duty to remove Japanese knotweed from your land unless it is causing a nuisance, but it must not spread off the property or into the wild.

Can I dig the soil out and put it in a skip?

The guidance says knotweed waste must not be disposed of with other surplus soil, and it must go to a permitted site through a registered waste carrier.

Does this apply in Wales or Scotland?

The GOV.UK page applies to England and links separate guidance for Scotland, Wales and Northern Ireland. Section 14 is worded differently in Scotland.

The bottom line

In England, Japanese knotweed in a garden does not have to be removed, but it must not spread, and soil contaminated with it can be controlled waste. Digging foundations near a stand of knotweed is the moment to bring in a specialist and plan disposal in advance. Section 14 of the Wildlife and Countryside Act 1981 makes causing a listed plant to grow in the wild an offence in England and Wales, subject to a due-diligence defence.

A conservatory project generates rubble, packaging and old materials, and the crew may need scaffolding to work on an existing wall or roofline. If a skip or scaffold has to stand on the public road or pavement rather than the drive, separate highway rules apply. This guide explains sections 139, 140 and 169 of the Highways Act 1980, which the legislation marks as extending to England and Wales, as they stand on legislation.gov.uk in September 2026. Scotland and Northern Ireland have their own roads legislation, which is not covered here. It is general information, not legal advice.

A skip on the highway needs permission

Section 139(1) states that a builders’ skip must not be deposited on a highway without the permission of the highway authority for that highway. A “builder’s skip” is defined in section 139(11) as a container designed to be carried on a road vehicle and placed on a highway or other land for storing builders’ materials, or for removing and disposing of builders’ rubble, waste, household and other rubbish or earth. A skip taken away after a conservatory base has been dug therefore falls within the definition.

Conditions and the skip owner’s duties

Section 139(2) allows the authority to grant permission unconditionally or with conditions covering the siting of the skip, its dimensions, the way it is painted so oncoming traffic can see it, the care and disposal of its contents, how it is lit or guarded, and its removal when the permission ends. Where permission has been granted, section 139(4) says the owner of the skip must ensure that it is properly lit during the hours of darkness, that it is clearly and indelibly marked with the owner’s name and a telephone number or address, that it is removed as soon as practicable after it has been filled, and that each condition of the permission is met.

The “owner” is normally the skip hire company, and for a hire agreement of one month or more it is the person in possession of the skip. A homeowner can ask the hire company before delivery whether permission has been granted.

Offences and removal on request

Depositing a skip without permission is an offence for the skip owner under section 139(3), with a fine of up to level 3 on the standard scale. Failing to meet the section 139(4) duties carries the same maximum. The legislation also records that subsections (3) to (7) cease to have effect in part in London under the London Local Authorities and Transport for London Act 2013, so London boroughs can operate a different local regime.

Section 140 applies even where permission was granted. The highway authority, or a constable in uniform, may require the skip owner to remove or reposition the skip, and section 140(3) makes failing to comply as soon as practicable an offence, again with a maximum fine at level 3.

Scaffolding: a written licence

Section 169(1) says that nobody may, in connection with building or demolition work or the alteration, repair, maintenance or cleaning of a building, erect or retain on or over a highway any scaffolding or other structure that obstructs the highway unless authorised by a written licence from the highway authority, and complying with its terms. The licence may contain any terms the authority thinks fit.

Under section 169(2), an authority that receives an application with the particulars it reasonably demands must issue the licence unless it considers that the structure would cause unreasonable obstruction, or that a differently erected structure would cause less obstruction and could conveniently be used for the work. An applicant refused a licence, or given terms they object to, may appeal to a magistrates’ court under section 169(3).

Under section 169(4) the licence holder must also ensure the structure is adequately lit between half an hour after sunset and half an hour before sunrise. Breaching the section without a licence, or failing without reasonable excuse to comply with its terms or duties, is an offence under section 169(5), with a fine of up to level 5 on the standard scale.

What to ask the installer

A homeowner can ask the installer whether the plan needs a skip or scaffold on the road, who applies for the permission or licence, and how long it lasts. The wider checks are in the guide to choosing a conservatory installer. Where the plot adjoins the road, the guide to building near a public highway covers a different set of highway questions, and noise conditions on the site are covered in the guide to noise from building work.

FAQs

Do I need permission for a skip on my own driveway?

Section 139 concerns skips deposited on a highway. A skip wholly on private land is outside that section.

Who is responsible if the skip has no permission?

Section 139(3) makes the skip owner liable, and section 139(5) provides that another person whose act or default caused the offence can also be guilty.

Does a scaffold on my own land need a licence?

Section 169 applies to scaffolding or structures erected or retained on or over a highway that obstruct it. Scaffolding wholly within the property boundary is outside that section.

The bottom line

In England and Wales, a builders’ skip on a highway needs the highway authority’s permission under section 139 of the Highways Act 1980, and obstructive scaffolding on or over a highway needs a written licence under section 169. Both come with conditions on lighting and marking, and both carry offences. This is general information, not legal advice on any specific site.

Building a conservatory involves cutting, drilling and excavation, and neighbours may hear it. The law gives councils tools to manage construction noise. Section 60 of the Control of Pollution Act 1974 lets a council serve a notice on how works are carried out, section 61 lets a builder apply in advance for consent, and statutory nuisance rules in the Environmental Protection Act 1990 can also apply. This guide describes those provisions for England and Wales as they stand on legislation.gov.uk in September 2026, and is general information, not legal advice on a particular dispute.

Works covered by section 60

Section 60(1) says the section applies to the erection, construction, alteration, repair or maintenance of buildings, structures or roads, breaking up, opening or boring under any road or adjacent land, demolition or dredging work and any work of engineering construction. Building or altering a conservatory falls within the first description, and removing an old one within demolition, which is covered in the guide to removing an old conservatory. The section does not itself fix a national set of working hours. Instead it gives the local authority power to set requirements for particular works.

What a section 60 notice can require

Where it appears to a local authority that works to which the section applies are being carried out, or are going to be, on any premises, it may serve a notice imposing requirements as to the way the works are carried out. Section 60(3) says the notice may specify the plant or machinery to be used or not used, the hours during which the works may be carried out, and the level of noise that may be emitted from the premises, at a specified point or during specified hours. The council must have regard to the need to use the best practicable means to minimise noise and to protect people in the locality.

The notice is served on the person who appears to be carrying out the works and on others the council thinks fit who are responsible for or control the works. The recipient may appeal to a magistrates’ court within 21 days from service under section 60(7). Contravening a requirement without reasonable excuse is an offence under section 60(8).

Prior consent under section 61

Section 61 allows a person who intends to carry out such works to apply to the local authority for consent in advance. The application must contain particulars of the works and the method, and of the steps proposed to minimise noise. If building regulations approval is required, the application must be made at the same time as or later than that request. The council must give consent if it considers the application contains sufficient information and that, if the works follow it, the council would not serve a section 60 notice. It may attach conditions, limit the duration and allow for changes in circumstances, and it must tell the applicant its decision within 28 days of receipt. Section 61(7) gives a right to appeal to a magistrates’ court within 21 days where consent is not given in time or is conditional. A consent does not of itself give a defence to proceedings under section 82 of the Environmental Protection Act 1990, according to section 61(9).

Statutory nuisance for noise

Under section 79(1)(g) of the Environmental Protection Act 1990, noise emitted from premises so as to be prejudicial to health or a nuisance is a statutory nuisance, and section 79(1)(ga) covers noise of that kind emitted from or caused by a vehicle, machinery or equipment in a street. The council must take reasonably practicable steps to investigate a complaint from a person living in its area. Under section 80, where it is satisfied that a noise nuisance exists or is likely to occur or recur, the council must either serve an abatement notice or take other steps to persuade the responsible person to abate it. If those steps do not work within a seven-day period, an abatement notice must follow. A person served with an abatement notice can appeal to a magistrates’ court within 21 days, and failing without reasonable excuse to comply is an offence.

What a homeowner can do

A homeowner who has commissioned a conservatory can ask the installer how noise will be managed, whether the council has served a notice or given consent, and what hours the crew works. The duties of a homeowner as a client are explained in the guide to domestic clients and CDM 2015, and the choice of installer is covered in the guide to choosing a conservatory installer. A neighbour who is affected can complain to the council under the statutory nuisance rules described above. Boundary and party wall questions are separate, as explained in the guide to the Party Wall Act 1996.

FAQs

Is there a legal limit on the hours a builder can work?

Section 60 does not set fixed hours. It allows a local authority to specify hours in a notice for particular works, so the position depends on any notice or consent for the site.

Can I appeal a council notice about building noise?

Yes. Section 60(7) provides for an appeal to a magistrates’ court within 21 days from service of the notice.

Does prior consent stop a neighbour complaining about a noise nuisance?

Not by itself. Section 61(9) says a consent does not of itself constitute a defence to statutory nuisance proceedings under section 82 of the Environmental Protection Act 1990.

The bottom line

In England and Wales, a council can serve a notice under section 60 of the Control of Pollution Act 1974 specifying plant, working hours and noise levels for building works, and a builder can apply in advance for consent under section 61. Noise from premises can also be a statutory nuisance under the Environmental Protection Act 1990. This is general information, not legal or planning advice on any specific property.

Approved Document F gives guidance on the ventilation requirement of the Building Regulations for dwellings in England, and it contains specific paragraphs on adding a conservatory. Its 2021 edition took effect on 15 June 2022, and GOV.UK also lists a 2026 edition for buildings subject to the 2026 standards. This guide summarises the conservatory paragraphs of both, applies to England only, and is general information. Approved documents are guidance, not the only way to comply, and building control should confirm what applies to a particular project.

When Part F applies to a conservatory

Approved Document F, Volume 1 says that its guidance on a new conservatory applies to conservatories with a floor area that exceeds 30 square metres, and that conservatories with a floor area not exceeding 30 square metres are exempt from the Part F requirements. That matches the wider Building Regulations exemption explained in the guide to the Class 7 exemption, and the exemption depends on the conditions there, including the thermal separation discussed in the guide to removing the thermal separating wall. A conservatory that falls outside the exemption must meet the ventilation requirement F1(1), which is about providing adequate means of ventilation.

Background ventilators for the general ventilation rate

Paragraph 3.22 says the general ventilation rate for a new conservatory and, if necessary, the adjoining rooms could be achieved using background ventilators. The guidance in paragraphs 1.42 to 1.44 of the 2021 edition is to be followed regardless of the ventilation provisions in the existing room next to the conservatory. Those paragraphs deal with a habitable room ventilated through another room or a conservatory. They say the conservatory should have openings to the outside that provide purge ventilation, with a minimum total area based on the combined floor area of the room and the conservatory, and background ventilation of at least 10,000 square millimetres equivalent area. Between the two rooms there should be a permanent opening with a minimum area of one twentieth of the combined floor area.

The 2026 edition contains the same conservatory section and adds a note in the equivalent paragraph that conservatories should be thermally separated from the rest of the dwelling, and that its paragraph 1.40, on the permanent opening between the rooms, does not apply to conservatories. Which edition applies depends on the standards applicable to the building, as GOV.UK explains, so building control should be asked.

Purge ventilation

For purge ventilation in a new conservatory, paragraph 3.23 directs the reader to the general purge ventilation paragraphs. Those say a system for purge ventilation should be provided in each habitable room, capable of extracting at least four air changes an hour per room directly to the outside, and delivered through openings such as windows or doors or through mechanical extract. Where openings are used, Table 1.4 sets minimum opening areas: hinged or pivot windows opening 15 to 30 degrees need a total area of one tenth of the floor area of the room, and those opening 30 degrees or more need one twentieth. Hinged or pivot windows opening less than 15 degrees are not suitable for purge ventilation. The table is based on assumptions in BS 5925, including single-sided ventilation, an urban environment and a temperature difference of 3 degrees Celsius. Smaller openings might work in some designs or climates, but expert advice should then be sought.

Controls and testing

Paragraph 3.24 says performance testing follows the general paragraph on component and system performance, and controls follow the general ventilation control paragraphs. Those say ventilation should be controllable, manually by the occupant or automatically, and that background ventilators should be at least 1,700 mm above floor level to reduce cold draughts while still being easy to reach. They add that background ventilators are intended normally to be left open. For a conservatory with roof or high-level vents, the guide to conservatory roof vents explains the types and how they work.

How it fits with other requirements

Approved Document F says that in order to show compliance with Part O on overheating, higher purge ventilation rates than those in its own tables are likely to be needed, but the guide to Part O and conservatories explains why that does not apply to most new conservatories. The wider set of building regulation issues is in the guide to conservatory building regulations. The document also stresses that following an approved document does not guarantee compliance, since it cannot cover all circumstances, and an alternative approach should be agreed early with the building control body.

FAQs

Does a small conservatory need to meet Part F?

Approved Document F says conservatories with a floor area that does not exceed 30 square metres are exempt from the Part F requirements.

Can background ventilators provide the ventilation for a larger conservatory?

Paragraph 3.22 says the general ventilation rate for a new conservatory and adjoining rooms could be achieved using background ventilators, following the paragraphs on ventilating a room through a conservatory.

Is there a minimum opening size for purge ventilation?

Table 1.4 gives minimum total opening areas as a fraction of the room floor area, depending on window type and opening angle, such as one twentieth for hinged windows opening 30 degrees or more.

The bottom line

In England, Approved Document F exempts conservatories of 30 square metres or less from Part F, and gives guidance for larger ones: background ventilators for the general rate, purge ventilation openings sized by Table 1.4, and controllable ventilation. The 2026 edition adds a note about thermal separation and the permanent opening. This is general information, not legal or planning advice on any specific property.

Under Part 8 of the Anti-social Behaviour Act 2003 a council can, after a complaint, decide whether a neighbour’s high hedge, a line of two or more mostly evergreen trees or shrubs more than two metres tall that is a barrier to light or access, harms the reasonable enjoyment of a home or its garden, and can issue a remedial notice, but it cannot order removal, cannot require a height below two metres and cannot deal with roots.

What counts as a high hedge

Section 66 of the Anti-social Behaviour Act 2003 defines a high hedge as so much of a barrier to light or access as is formed wholly or predominantly by a line of two or more evergreens and rises to more than two metres above ground level. Evergreen includes semi-evergreen trees and shrubs. A line is not treated as a barrier if gaps significantly affect its overall effect at heights above two metres. GOV.UK guidance for England adds that the hedge must be on land owned or occupied by someone else, that a single tree or shrub does not qualify, and that height is measured from ground level, usually the base of the trunk or main stem. The guide covers England; Wales is not covered here.

How a conservatory fits into the test

The law asks whether the hedge’s height adversely affects the reasonable enjoyment of a domestic property. Under section 65, the complaint must come from an owner or occupier of a domestic property. GOV.UK says councils can consider harm to a home and/or its garden or yard, and a conservatory is part of the home, so the effect on it can be described in a complaint, which should explain what the problems are and how serious they are. GOV.UK also says the further the hedge is from the home, the harder it is to show harm. The guide to right to light covers the separate legal question of light lost to a neighbour’s building.

What has to happen before a complaint

The council can reject a complaint if it thinks the complainant has not taken all reasonable steps to settle the dispute without involving it, so steps to settle it informally come first. If the council accepts the complaint, GOV.UK says a fee will most likely be payable, that some councils offer reduced fees for people on a low income or benefits, and that the fee is not usually refunded even if the complaint succeeds. The complaint must be in writing, and GOV.UK says it should set out the steps taken to settle the dispute, the problems in the home or garden, why they are serious and how the hedge affects reasonable enjoyment.

What the council can and cannot order

If the council decides the hedge is adversely affecting reasonable enjoyment, it can issue a remedial notice setting out the action to be taken and by when. Under section 69, the notice must take effect at least 28 days after it is issued. The action specified cannot require the height of the hedge to be reduced to less than two metres above ground level or the removal of the hedge. GOV.UK says the legislation does not set a specific height and that two metres will only be the right height in some cases. The notice may also require the hedge to be kept at its new height, and the time allowed to cut it could be weeks or months, including extra time to protect birds nesting in the hedge, which links to the guide to nesting birds and conservatory building.

Roots and subsidence are outside the procedure

Section 65(4) states that Part 8 does not apply to complaints about the effect of the roots of a high hedge, and GOV.UK says the same about subsidence: hedge roots can take moisture from soils that shrink, but councils cannot deal with problems caused by roots. GOV.UK’s neighbour-disputes page separately says a person can trim branches or roots that cross into their property from a neighbour’s land, but only up to the boundary, and that exceeding this could lead to a court claim for damage. If the tree or hedge is protected, or in a conservation area, council permission may be needed before trimming, as explained in the guide to tree preservation orders and conservatories.

FAQs

Can a council make my neighbour remove a hedge blocking my conservatory?

No. GOV.UK says the council cannot order removal of the hedge, action that could kill it, or a height below 2 metres.

Does the process cover a single large tree?

No. GOV.UK says single trees or shrubs are not covered, although the parties can still try to settle the dispute informally.

Can I complain about roots damaging my conservatory foundations?

Not under this procedure. Section 65(4) says Part 8 does not apply to complaints about the effect of the roots of a high hedge.

The bottom line

In England, Part 8 of the Anti-social Behaviour Act 2003 lets a council act on a neighbour’s evergreen hedge over two metres tall that blocks light to a home or garden, including a conservatory, but only after reasonable steps to settle the dispute, usually with a fee, and with limits on what the notice can require. Roots and subsidence are outside it. This is general information, not legal advice.

In England it is an offence to intentionally take, damage or destroy a wild bird nest while it is in use or being built, to intentionally kill, injure or take wild birds, or to take or destroy eggs; GOV.UK says Natural England cannot issue a wild bird licence to allow development, so the practical answer for a conservatory project is to time clearance to avoid the breeding season.

What the law protects

GOV.UK guidance from Natural England and Defra, which applies to England, says all wild bird species, their eggs and nests are protected by law. It lists what is unlawful: intentionally killing, injuring or taking wild birds, intentionally taking, damaging or destroying a wild bird’s nest while it is being used or built, and intentionally taking or destroying a wild bird’s egg. Natural England’s planning guidance ties this to the Wildlife and Countryside Act 1981. A guilty person could get an unlimited fine and up to six months in prison for each offence, according to GOV.UK.

Schedule 1 birds and extra protection

Some birds are listed in schedule 1 of the 1981 Act, for example barn owls, and receive extra protection. For these species GOV.UK says it is also an offence to disturb them while they are nesting, building a nest, or in or near a nest that contains young, and to disturb their dependent young. Natural England’s standing advice describes the offence as intentionally or recklessly disturbing a schedule 1 bird on or near a nest containing eggs or young, when it is building a nest, or its dependent young. For a householder, the practical point is that a site with a known protected nest, such as a barn owl in an outbuilding or old tree, calls for specialist advice before work begins. Bats are covered separately in the guide to bats and conservatory building.

Activities on a conservatory project that can affect birds

GOV.UK lists activities that can affect wild birds, particularly during the breeding season: trimming or cutting trees, bushes, hedges and rough vegetation; renovating, converting or demolishing a building; creating disturbance such as noise, lighting and vibration; and actions to prevent problems, such as removing nests. On a conservatory project, that maps onto clearing shrubs and hedging to make room for the base, removing an old shed or lean-to, and altering a wall where a bird has nested. Trees near the footprint may also carry protection, as covered in the guide to tree preservation orders and conservatories, and that is a separate legal question from nesting birds.

Timing and methods that avoid harm

GOV.UK says that in most cases harm to wild birds can be avoided by timing work to avoid the breeding season and by using a range of methods that deter but do not harm them. The guidance does not fix the breeding season as a single date, so vegetation clearance is best programmed outside spring and summer, or, if it cannot be moved, preceded by a check for active nests by a competent person. Nests that are being used or built are the ones the offence describes.

No licence for development, and the planning angle

GOV.UK states that there are no licensing purposes to permit development or construction, but there are ways to continue when birds are present, relying on the legal exemptions, and that the person relying on an exemption must be sure they can comply fully with its terms. Natural England’s standing advice for planners says the developer must comply with the legal protection of all wild birds and that Natural England cannot issue a wild bird licence to allow development. The standing advice also says a survey may be requested where a proposal affects mature gardens, trees with holes, cracks and cavities, or buildings that could support nesting birds. Where no planning application is made, as with permitted development, that assessment does not take place, but the legal protection still applies to the homeowner and the builder. For the ecology rules that apply to a householder project, the guide to biodiversity net gain and your conservatory is a useful companion.

FAQs

Can I remove a nest to build my conservatory?

GOV.UK lists intentionally taking, damaging or destroying a wild bird’s nest while it is being used or built as unlawful, and says there are no licensing purposes to permit development.

When is the bird breeding season?

GOV.UK advises timing work to avoid the breeding season but the guidance does not fix a single date, so advice should be taken from a competent ecologist if clearance cannot avoid spring and summer.

What is the penalty?

GOV.UK says an unlimited fine and up to 6 months in prison for each offence.

The bottom line

In England every wild bird nest that is in use or being built is protected, schedule 1 birds have extra protection against disturbance, and Natural England cannot license development. For a conservatory project, clearing hedges, shrubs and old structures outside the breeding season, and checking for active nests before any clearance, is the practical way to stay within the law. This is general information, not legal or ecological advice.

HSE guidance for Great Britain warns that damage to underground electricity cables can cause fatal or severe injury, and says work should be planned, service plans obtained, cables located with a device and marked before digging, and excavation carried out alongside rather than directly above a service, all of which applies when foundations for a conservatory are dug.

Why foundations bring the risk

Conservatory foundations need trenches or pits, and gardens can contain buried services. The Health and Safety Executive (HSE) says that when underground cables are damaged, people can be killed and injured by electric shock, electrical arcs (which can cause an explosion) and flames, often with severe burns to the hands, face and body even where protective clothing is worn. Damage can be caused when a cable is cut through by a sharp object such as the point of a tool, or crushed by a heavy object or powerful machine, and cables damaged earlier but left unreported and unrepaired can also cause incidents. HSE’s guidance applies in Great Britain. Foundation design is a separate question, covered in the guide to conservatory foundations, ground conditions and trees.

Planning before any digging

HSE says most service cables belong to a Distribution Network Operator, though some belong to organisations such as the highways authority, the Ministry of Defence or Network Rail, and the person planning the work should check nearby for equipment owned by them and, if underground cables are suspected, ask for plans to confirm their location. It may be necessary to ask someone from the organisation to attend and locate the cables accurately. Careful planning and risk assessment are essential before work starts, and plans or other suitable information about all buried services in the area should be obtained and reviewed before any excavation. If a supply must be made dead for the work to proceed safely, HSE notes that electricity companies are required to give five days’ notice to customers whose supply is to be disconnected, so a disconnection cannot be arranged on the day.

Plans are only an indication

HSE is clear that plans give only an indication of the location and number of underground services at a site. It says a competent person should trace cables using suitable locating devices, and that before work begins underground cables must be located, identified and clearly marked. Locators should be used frequently and repeatedly during the work, and people who use them should be thoroughly trained in their use and limitations, with devices used according to the manufacturer’s instructions and kept in good working order. Symbols on cable plans can vary between utilities, and high-voltage cables may appear on separate plans from low-voltage ones, so advice should be sought from the office that issued the plan. If an emergency excavation is carried out and no plans can be found, HSE says the work should be treated as though live buried services are in the area.

Safe digging practice

Once cables have been located, HSE says excavation may take place, with trial holes dug using suitable hand tools as needed to confirm their position. Digging should be alongside the service rather than directly above it, and final exposure of the service by horizontal digging is recommended because the force applied to hand tools can be controlled more effectively. Insulated tools should be used when hand digging near electric cables. Separately, HSE’s excavation guidance lists underground and overhead services among the key issues for any excavation, together with collapse, falling material and people or plant falling in, and says plant and vehicles should not be parked close to the sides of an excavation.

Overhead lines and the domestic client

HSE publishes separate guidance note GS6, “Avoiding danger from overhead power lines”, aimed primarily at employers and employees who are supervising or in control of work near live overhead lines. It is relevant where a mini-digger, delivery lorry or crane may work close to wires above a garden. HSE says the law requires precautions to avoid danger from underground cables and that commercial clients must give contractors information on ground conditions, underground structures or watercourses and the location of existing services. Those client duties are for commercial clients. A householder commissioning a conservatory is a domestic client (see the guide to domestic clients under CDM 2015). Sewer and drain constraints are separate; see the guide to building near or over a drain.

FAQs

Who is responsible for finding buried cables before a conservatory base is dug?

HSE guidance is written for the people planning and carrying out the excavation, who should obtain plans, locate and mark cables and dig safely. For a homeowner, the contractor normally takes on that role.

Can cable plans be relied on to show exactly where a cable runs?

No. HSE says plans give only an indication of the location and number of services and that a competent person should trace cables with suitable locating devices.

The bottom line

HSE guidance for Great Britain sets out the safe approach to digging near buried services: plan the work, obtain plans, locate and mark cables with a device, and dig alongside the service, using hand tools and insulated tools near electric cables. A conservatory installer should be able to explain how these steps will be followed before foundations are dug. This is general information, not health and safety advice for any specific site.

When a home is sold in the UK, Private Residence Relief means no Capital Gains Tax is due if the owner has one home, has lived in it as their main home throughout, has not let part of it out or used part exclusively for business, the grounds are under 5,000 square metres and it was not bought just to make a gain; where tax is due, GOV.UK says the costs of improvement works such as an extension can be deducted from the gain.

The starting point: Private Residence Relief

Capital Gains Tax applies to the gain made when property is sold. GOV.UK sets out when a home sale is free of it. No Capital Gains Tax is payable if all of the following apply: the owner has one home and has lived in it as their main home for all the time they have owned it; they have not let part of it out (a lodger does not count); they have not used a part of it exclusively for business purposes; the grounds, including all buildings, are less than 5,000 square metres (just over an acre) in total; and they did not buy it just to make a gain. If all of these apply, the relief is automatic and there is no tax to pay.

When a conservatory can complicate the position

A conservatory can matter to the conditions in two ways. If it is used as an office, GOV.UK says a room used as a temporary or occasional office does not count as exclusive business use. A part of the home used exclusively for business is one of the listed conditions. Second, letting part of the property out is another. GOV.UK says that if any of the conditions do not apply, there may be some tax to pay, and points to its guidance on eligibility. The guide to using a conservatory as a home office covers the practical side of the space.

Working out the gain

Where tax may be due, the gain is usually the difference between what was paid for the home and what it was sold for. GOV.UK says market value is used instead in certain cases, including where the property was a gift, was sold for less than it was worth to help the buyer, was inherited and the Inheritance Tax value is not known, or was owned before April 1982. These points are set out in the GOV.UK guide for a home sale.

Deducting the cost of a conservatory

GOV.UK states that the costs of buying, selling or improving a property can be deducted from the gain. Those costs include estate agents’ and solicitors’ fees, and the costs of improvement works, for example for an extension. Normal maintenance costs such as decorating do not count. A conservatory is an extension of the home, so the cost of building it is the kind of improvement expense that the guidance describes, whereas repainting the frames or replacing worn seals is maintenance. GOV.UK also says some costs cannot be deducted, such as interest on a loan to buy the property, and advises contacting HMRC where it is unclear whether a cost can be deducted.

Reporting and paying

If Capital Gains Tax is payable, GOV.UK says it must be reported and paid on most sales of UK property within 60 days. The tax-free allowance for individuals, which GOV.UK gives as £3,000 (£1,500 for trusts) when checked on 25 September 2026, is a separate figure that can be set against gains; allowances are set for each tax year, so the current figure should be checked at the time of sale. VAT on the works is covered in the guide to VAT on conservatories, and buyers’ checks on a home with a conservatory are covered in the guide to buying a house with a conservatory.

FAQs

Do I pay Capital Gains Tax on my home if I added a conservatory?

Not if Private Residence Relief applies in full, which GOV.UK says is automatic when all its conditions are met. A conservatory does not by itself remove the relief.

Can I deduct the cost of building a conservatory from my gain?

GOV.UK says the costs of improvement works, for example for an extension, can be deducted from the gain, while normal maintenance costs do not count.

Does a home office in a conservatory affect the relief?

GOV.UK says a room used as a temporary or occasional office does not count as exclusive business use, but exclusive business use of part of a home is one of the conditions to check.

The bottom line

Selling a home with a conservatory is usually free of Capital Gains Tax under Private Residence Relief. Where tax is due, GOV.UK says the cost of improvement works such as an extension can be deducted from the gain, and any Capital Gains Tax on most UK property sales must be reported and paid within 60 days. This is general information, not tax advice; HMRC or a qualified tax adviser should confirm the position for a specific sale.
