In England, a single-storey rear extension, including a conservatory, can extend up to eight metres from the rear wall of a detached house or six metres for other houses under permitted development if the local planning authority is asked to decide whether its prior approval is required, and neighbours are consulted as part of that process.

The standard limit and the larger limit

The Planning Portal, which describes the planning system in England (and says policy in Wales may differ), explains that a single-storey rear extension under permitted development cannot extend beyond the rear wall of the original house by more than four metres for a detached house, or three metres for any other house. Where the property is not on Article 2(3) designated land or a Site of Special Scientific Interest, and subject to prior approval, that limit is increased to eight metres for a detached house or six metres for any other house. Single-storey rear extensions also cannot exceed four metres in height.

The Planning Portal says these permitted development rules summarise Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015. They apply to houses, not flats and maisonettes, converted houses or houses created under certain change-of-use rights, and they do not apply where a planning condition, Article 4 Direction or other restriction removes the rights.

What counts as the original house and designated land

The “original house” is the house as first built, or as it stood on 1 July 1948 if built earlier, so earlier extensions by previous owners count towards the limits. Article 2(3) designated land includes conservation areas, areas of outstanding natural beauty, the Broads, National Parks and World Heritage Sites, and the larger 8m/6m limits are not available there.

How the application works

A householder applies to the local planning authority, providing a written description that states how far the extension projects beyond the rear wall of the original house, the height at the eaves and the highest point, a site plan showing the proposal and any existing enlargement it joins, the addresses of adjoining properties including those to the side, front and rear even if not physically attached, and contact details. The Planning Portal guidance note (version 2024.1 for England) says a plan drawn to scale helps, and that if information is insufficient the authority can ask for more or refuse the application.

There is a fee for most prior approval applications. The guidance note says it can be waived if the proposal is solely for extensions and alterations to a disabled person’s dwelling to improve access, safety or comfort, or if a planning application for the same site is made by the same applicant on the same date and a fee is payable for it.

Neighbour consultation and the 42-day period

The authority serves a notice on adjoining owners or occupiers, describing the proposal and stating when the application was received, when the 42-day determination period ends and the date by which objections must be received, which must give neighbours at least 21 days. If any adjoining neighbour objects within that period, the authority’s prior approval is required and it must decide whether the impact on the amenity of all adjoining properties is acceptable. The development can go ahead if the authority notifies the developer in writing that prior approval is not required because no objections were received, or that it has found the effect on amenity acceptable. If the authority does not notify a decision within the 42-day period, the development may go ahead. A refusal can be appealed.

Conditions and cautions

The guidance note stresses that all other permitted development restrictions and conditions still apply, and that it is not possible to use the prior approval process retrospectively, so it must be completed before work starts. The extension must be built in accordance with the details approved or, where no objections were raised or no decision was made, the details submitted, unless the authority agrees changes in writing.

The Planning Portal also notes that an extension adding more than 100 square metres of floor space may be liable for the Community Infrastructure Levy, and that permitted development is separate from Building Regulations, which must be considered independently. Its guidance is introductory, and local rules may affect what is needed, so a householder should confirm the position with the local planning authority.

FAQs

Does a conservatory count as a single-storey rear extension?

The Planning Portal says that adding a conservatory to a house falls within the same planning rules as any other home extension, so the single-storey rear extension limits and the prior approval process apply.

What happens if a neighbour objects?

The authority must then decide whether the impact on the amenity of all adjoining properties is acceptable before the extension can proceed, according to the Planning Portal guidance note.

Does this apply in Wales, Scotland or Northern Ireland?

The Planning Portal guidance relates to England, and it says policy in Wales may differ. Scotland and Northern Ireland have their own planning rules.

Bottom line

The larger 8m and 6m rear extension limits in England depend on prior approval: apply first, allow the neighbour consultation and 42-day period, and build only to the approved or submitted details. The route is unavailable on designated land and cannot be used after building has started. This is general information, not planning advice; confirm requirements with your local planning authority.

GOV.UK says a flood risk assessment is required for all development, including minor extensions, that needs a planning application in Flood Zones 2 or 3, and it treats a householder extension of up to 250 square metres as a “minor extension”.

When a flood risk assessment is needed

GOV.UK’s guidance for planning applicants in England says you should complete a flood risk assessment (FRA) for all development, including minor development, proposed in Flood Zones 2 or 3 or within Flood Zone 3b. It also applies in some Flood Zone 1 cases, such as sites of 1 hectare or more or where the flood map for planning shows surface water risk. The local planning authority may refuse an application without a satisfactory FRA. The guidance is written for people applying for planning permission, so ask your council whether your conservatory needs an application and check the flood map for planning first.

GOV.UK adds that if your site is in Flood Zone 1 but the council’s strategic flood risk assessment or the flood map for planning shows increased future flood risk from rivers or the sea, you should complete an FRA and apply the guidance as if the site were in Flood Zone 2. It also mentions areas with critical drainage problems, currently designated only in Devon and Cornwall, where local standing advice applies and can be obtained from the council.

What counts as a minor extension

GOV.UK defines a minor extension as a householder or non-domestic extension with a floor space of no more than 250 square metres. For a minor extension in Flood Zone 2, 3 or 3b, applicants should follow the Environment Agency’s standing advice for minor extensions, covering what to include in the FRA, floor levels, extra flood resistance and resilience measures, and other permissions or consents. The guidance says a simple, low-risk development such as a house extension may be something you can assess yourself, but if you are unsure you should contact the Environment Agency for advice.

What the assessment should contain

The standing advice says an FRA should be proportionate and include your site address, a description of the development, the estimated flood level taking climate change into account, finished floor levels, flood resistance and resilience plans and any supporting drawings. It suggests using the Environment Agency’s FRA template. The design flood is a river flood with a 1 in 100 annual probability or a tidal flood with a 1 in 200 annual probability, each plus a climate change allowance, and a surface water event of 1 in 100 plus climate change. Levels should be stated relative to Ordnance Datum, and you may need a land survey by a qualified surveyor if that information is not available.

Floor levels and resilience

The advice recommends floor levels at least 600mm above the estimated flood level, with flood-resistant materials used up to at least 600mm above it. It says this may be reduced to 300mm if there is a high level of certainty about the estimated flood level, and increased where there is particularly high uncertainty. If your design aims to keep out more than 600mm of water, get advice from a structural engineer, because flood water puts pressure on buildings. Where you cannot raise floor levels, you need extra flood resistance and resilience measures, aiming to exclude flood water where possible and speed recovery if water gets in, and your plans must show how surface water and groundwater flooding will be managed.

Functional floodplain, off-site risk and other consents

The advice says to check with the local planning authority whether your minor extension is in an area of increased flood risk because of multiple minor extensions, and if so to assess off-site flood risk. In Flood Zone 3b, the functional floodplain, table 2 of the planning practice guidance says highly vulnerable, more vulnerable and less vulnerable development should not be permitted. You may also need a separate permit or consent if the work is within 20 metres of a main river, flood defence or flow control structure, directly affects a watercourse, or involves floodplain activity that could divert or obstruct floodwater. GOV.UK stresses that getting planning permission does not guarantee a flood risk permit or consent, so check early.

FAQs

Do I need an FRA if my conservatory is permitted development?

The GOV.UK guidance addresses planning applications. If no application is needed, ask your council and the Environment Agency what applies, and check for other consents near watercourses or defences.

Does this apply in Wales, Scotland or Northern Ireland?

The guidance is for England, referring to the Environment Agency and English planning practice guidance. Other nations have their own flood risk policies.

How do I find my flood zone?

GOV.UK says to use the Environment Agency’s flood map for planning to find whether the site is in Flood Zone 1, 2 or 3 and whether it is at risk of surface water flooding.

Bottom line

If your English conservatory project needs a planning application and lies in Flood Zone 2 or 3, expect to submit an FRA that follows the Environment Agency’s minor extension advice, including estimated flood levels and floor levels or resilience measures, and check for river-related permits. Ask your planning authority early. This is general information, not planning or engineering advice.

The Consumer Contracts Regulations 2013 give a 14-day right to cancel distance and off-premises contracts, which include many contracts signed at your home, but they exclude goods made to your specifications or clearly personalised.

Where the right to cancel applies

Regulation 29 of the Consumer Contracts Regulations 2013 lets a consumer cancel a distance or off-premises contract within the cancellation period without giving a reason. The Regulations extend to England, Wales, Scotland and Northern Ireland, so the rules discussed apply UK-wide. An off-premises contract includes one concluded in the simultaneous physical presence of the trader and the consumer in a place that is not the trader’s business premises, such as your home, and certain contracts following an offer or personal approach outside business premises. A contract signed at a showroom on the trader’s premises is an on-premises contract, so this statutory right does not apply, although your contract may give its own terms.

Regulation 29 says cancelling does not make you liable for anything except under a short list of provisions, covering enhanced delivery you chose, reduced value of goods through handling, the cost of returning goods and payment for a service supplied early at your request. It also says you can withdraw an offer to enter into such a contract at any time before the contract is made, without giving a reason and without liability.

How long you have

For a service contract, regulation 30 says the cancellation period ends at the end of 14 days after the day the contract is entered into. For a sales contract, it ends 14 days after the goods come into your physical possession. A conservatory agreement often combines supplying the structure with installing it, so which rule fits your contract is worth checking before you rely on a date. If in doubt, act within 14 days of signing and take advice from Citizens Advice or your local Trading Standards service.

Regulation 30(5) adds that where goods consisting of multiple lots or pieces are delivered on different days, the period for a sales contract ends 14 days after the last piece comes into your physical possession, which is relevant to structures delivered in parts.

If you were not told about your right

Regulation 31 extends the period if the trader does not give you the required information on the right to cancel. If the trader provides the information within 12 months of the start of the 14 days, the period ends 14 days after you receive it. Otherwise it ends 12 months after the day it would normally have ended. Keep the paperwork you were given at signing and note whether it contained a clear cancellation notice.

Starting work early

Regulation 36 says a trader must not begin the supply of a service before the end of the cancellation period unless you have made an express request, and, for an off-premises contract, made that request on a durable medium. If you cancel after asking the trader to start early, you must pay an amount in proportion to what has been supplied up to the point you tell the trader, calculated on the agreed total price or, if the price is excessive, on the market value of the service. You bear no cost if the trader failed to give the required information on cancellation and payment or if the service was not supplied in response to your request. You lose the right to cancel if the service has been fully performed after your request and your acknowledgement that you would lose the right.

The personalised-goods exception

Regulation 28(1)(b) says the cancellation right does not apply to the supply of goods made to the consumer’s specifications or clearly personalised. Whether that exception applies to a particular conservatory contract, which may cover bespoke components and also installation, depends on the terms and facts, so do not assume either way. Ask the trader in writing how they classify the contract and which parts are custom-made, and seek independent advice if you are told you cannot cancel. Regulation 28 also excludes contracts where you specifically requested an urgent repair visit, which is unlikely to apply to a new conservatory order.

FAQs

What if I signed in the showroom?

The statutory cancellation right applies to distance and off-premises contracts. A showroom contract is an on-premises contract, so check your written terms for any contractual right to cancel.

Do I have to give a reason for cancelling?

No. Regulation 29 says you may cancel at any time in the cancellation period without giving any reason and without liability except under specified provisions.

Does this apply in Scotland and Northern Ireland?

Yes. The Regulations extend to England, Wales, Scotland and Northern Ireland, although court procedures differ in each nation.

Bottom line

If you signed a conservatory contract at home, note the date immediately, check what you were told about cancelling, and be careful about agreeing to an early start. Whether the personalised-goods exception applies can be contested, so take advice before assuming you are locked in. This is general information, not legal advice.

Restrictive covenants have nothing to do with the town and country planning system, so a covenant in your title can prevent development even if it has planning permission.

What a restrictive covenant is

According to the Upper Tribunal (Lands Chamber) guidance published on GOV.UK, a restrictive covenant is a legally binding restriction imposed on land by agreement between two freehold landowners or contained in a lease. It is often imposed when land is sold, for example to prevent the buyer using the land for business or building on it, or to make sure they keep to a particular style or size of building. Covenants are imposed by deed and are private arrangements: only the person who imposed the covenant, and anyone who later owns any of that person’s land, can enforce it.

Why planning permission does not settle the question

The tribunal guidance is explicit that restrictive covenants have nothing to do with the town and country planning system, and that a covenant can prevent development even if it has planning permission. That matters for conservatories because our other guides explain permitted development and planning applications. Those rules decide whether the council needs to be involved, not whether a private covenant allows you to build. The guidance gives examples of covenants that prevent building on land or require buildings to keep to a particular style or size.

Finding out whether your property is affected

HM Land Registry holds information about registered property in England and Wales, and GOV.UK says you can get information even about property you do not own, including the title register. The tribunal guidance says that when land is registered, it is usually obvious from the registered title whether it is subject to restrictive covenants. Land may be affected by covenants imposed many years ago, for example when land was sold for housing in the 20th or even 19th centuries, and the guidance warns that it can be difficult to tell who can enforce a covenant and old conveyancing documents may have to be inspected even where the land is registered. This article covers England and Wales; land law in Scotland and Northern Ireland differs.

GOV.UK describes the title register as a document giving details such as who owns the property, rights of way and whether a mortgage has been discharged. The tribunal guidance adds that the register does not usually show that land has the benefit of covenants over other land, so someone who wants to enforce or object to a covenant may need legal advice to establish their entitlement.

Applying to modify or discharge a covenant

The owner of land, freehold or leasehold, that is subject to a restrictive covenant may apply to the Lands Chamber of the Upper Tribunal under section 84 of the Law of Property Act 1925 to have it discharged or modified. The tribunal has no power to change positive covenants, which require an owner to do something, or easements such as rights of way. The applicant uses Form T379 and submits it with the specified documents and the fee. The registrar then gives directions for notice to those who may benefit from the covenant, which may involve a newspaper advertisement, notices on the land or a publicity notice.

Objections, hearings and costs

Anyone wishing to object must submit a notice of objection within one month of the notice date, and no fee is payable to object. The applicant then has 14 days to say whether it accepts that the objector is entitled to the benefit of the covenant, and disputed entitlement can be decided by the tribunal. Where there are no objections, the tribunal may decide without a hearing. The guidance says successful objectors will generally be awarded their reasonable costs, while successful applicants cannot expect costs. It also notes that the law on restrictions affecting land is complex and it is advisable to seek legal advice before applying.

FAQs

Is a covenant the same as a planning condition?

No. The tribunal guidance says covenants have nothing to do with the planning system and are private arrangements enforceable by those who have the benefit of them.

Can a neighbour enforce a covenant?

Only the person who imposed it and anyone who later owns any of their land can enforce it, according to the tribunal guidance, which is why identifying who benefits can be complex.

Does the tribunal handle every covenant problem?

No. The guidance says the tribunal cannot discharge or modify positive covenants or easements such as rights of way. Take legal advice about your title.

Bottom line

Before you commit to a conservatory, read the title register for your property and ask your solicitor about any restrictive covenants, rather than assuming planning permission or permitted development is enough. If a covenant blocks your plans, an application to the Upper Tribunal (Lands Chamber) is one route, but it is a legal process with notice, objections and costs risks. This is general information, not legal advice.

All bat species and their breeding sites and resting places are fully protected by law in England, and building work that damages a roost or disturbs bats can be a criminal offence even when it is accidental.

Why a conservatory can raise wildlife questions

GOV.UK’s Natural England guidance, which covers England, lists activities that can harm bats. They include renovating, converting or demolishing a building; repairing or replacing a roof; repointing brickwork; insulating or converting a loft; installing lighting in a roost or outside where it lights up a roost entrance; cutting down or removing branches from a mature tree; removing hedgerows, watercourses or woodland that bats use for commuting; and changing or removing foraging areas. A conservatory build that involves connecting to a roof, altering brickwork, adding lighting or clearing trees or hedges could involve some of these activities, so it is worth checking before work begins.

What the law protects

The guidance says all bat species, their breeding sites and resting places are fully protected by law as European protected species. You are breaking the law if you deliberately capture, injure or kill bats; damage or destroy a breeding or resting place; obstruct access to their resting or sheltering places; possess, sell, control or transport live or dead bats; or intentionally or recklessly disturb a bat in a structure or place of shelter. GOV.UK’s wider guidance on construction and wildlife adds that this includes doing so by not taking enough care, and that damage to a breeding or resting place is an offence even if accidental. Offenders could be sent to prison for up to six months or receive an unlimited fine.

Other protected species and areas

GOV.UK lists European protected species that include all species of bat, beavers, great crested newts, dormice, otters, natterjack toads and some reptiles. Other protected species and groups include badgers, water voles, wild birds, ancient woodland and veteran trees. You must apply for a licence if your plans affect badgers or European protected species, and, following changes under the Environment Act 2021, a mitigation licence is also needed for animals and plants listed in schedules 5 and 8 of the Wildlife and Countryside Act 1981. You are responsible for finding out whether your development is likely to affect a protected area, such as a national park, area of outstanding natural beauty or site of special scientific interest, because a planning authority may refuse permission where a protected site would be damaged.

What to do if you suspect bats

If you think there is a bat roost in or near your house, GOV.UK says you can contact the National Bat Helpline, run by the Bat Conservation Trust on behalf of Natural England, for free advice on small-scale works, pest control or other concerns. The helpline cannot advise on building works that need planning permission and can arrange for a volunteer roost visitor if needed. In many cases harm can be avoided, and GOV.UK says you will need an expert bat survey, showing what type of bats, how many and how they use the building, so you can plan the work to avoid harming them. It points to the directories of the Chartered Institute of Ecology and Environment Management and Environmental Data Services for finding a surveyor.

Licences and planning the work

If harm cannot be avoided, you can apply to Natural England for a mitigation licence, but GOV.UK says applying for a licence should be a last resort and applies only in a minority of cases. Before that, it says you should try everything possible to avoid disturbing the species, for example by timing work to cause the least harm or using other mitigation methods that do not need a licence. An application must include survey findings, impact assessments and mitigation plans. Ecological consultants may be able to use a class licence for certain low-impact activities. If you have doubts, ask your local planning authority and an ecologist before signing a construction contract.

FAQs

Is it an offence to disturb bats accidentally?

GOV.UK says it is an offence to damage or destroy a breeding or resting place even accidentally, and to disturb or injure protected species by not taking enough care. Intentional or reckless disturbance of a bat in a shelter is also an offence.

Does this apply in Wales, Scotland and Northern Ireland?

The GOV.UK guidance refers to Natural England and applies in England. Other nations have their own agencies and licensing arrangements, so check locally.

Who can I call if I find bats?

The National Bat Helpline, run by the Bat Conservation Trust for Natural England, offers free advice on small-scale works and pest control, according to GOV.UK, but not on works that need planning permission.

Bottom line

Before building a conservatory in England, check whether the works will touch a roof, wall, tree or hedge where bats or other protected species could be present, and stop and take advice if you see signs of a roost. Damage to a roost is an offence even if unintended, so use an expert survey and, if necessary, a Natural England licence rather than risking prosecution. This is general information, not legal or ecological advice.

In Northern Ireland, a conservatory is dealt with under Part 1, Class A of the Planning (General Permitted Development) Order (Northern Ireland) 2015, which sets dimension limits and extra restrictions in designated areas.

A separate planning system

Planning in Northern Ireland is governed by its own legislation and, in practice, dealt with by councils. The Planning (General Permitted Development) Order (Northern Ireland) 2015 applies to all land in Northern Ireland, and nidirect, the Northern Ireland government’s public information service, says that under permitted development rights you do not need planning permission for certain works provided they meet certain conditions, such as dimension restrictions when building an extension. It advises contacting your council planning office to check whether your work is allowed. This article summarises the Order’s Class A; it does not cover England, Wales or Scotland, which have their own rules covered in other guides on this site.

How a conservatory fits into Class A

Part 1, Class A of the Order permits the enlargement, improvement or other alteration of a dwellinghouse, subject to limits. The Order’s conditions expressly exclude “materials used in the construction of a conservatory” from the requirement that exterior materials match the existing house, which indicates that conservatories are dealt with as enlargements under Class A rather than as a separate category. If your proposal falls outside the limits, you would need to apply for planning permission.

The main size and position limits

Under Class A.1, development is not permitted if, as a result of the works, the ground covered by buildings within the curtilage (other than the original dwellinghouse) would exceed 50 per cent of the curtilage, excluding the original house’s footprint; or if the height of the enlarged part would exceed the highest part of the roof of the existing house, or its eaves would exceed the existing eaves; or if it would extend beyond a wall facing a road that forms the principal or a side elevation of the original house.

Single-storey extensions and boundaries

For an enlarged part with a single storey, development is not permitted if it extends beyond the rear wall of the original house by more than 4 metres for a detached house or 3 metres for any other house, exceeds 4 metres in height, or is within 3.5 metres of the curtilage boundary with a road opposite the rear wall. It is also not permitted if the enlarged part would be within 2 metres of any boundary and the eaves would exceed 3 metres, or if it would extend beyond a side elevation wall and exceed 4 metres in height or be wider than half the width of the original house. Multi-storey enlargements are subject to separate limits.

Designated areas and listed buildings

In a conservation area, World Heritage Site, area of outstanding natural beauty or National Park, Class A.2 says development is not permitted if it would include cladding the exterior with stone, artificial stone, pebbledash, render, timber, plastic or tiles; if the enlarged part would have more than one storey or exceed 4 metres in height; or if it would extend beyond a wall forming the principal or a side elevation. Class A.1 also excludes a dwellinghouse within the curtilage of a listed building unless listed building consent has previously been granted. Class A also does not permit development that includes an alteration to any part of the roof, a raised platform or deck, a basement, a chimney, flue or soil and vent pipe, or a microwave antenna.

When you must apply, and what to check

nidirect says you need to apply for planning permission to add to or extend a flat or maisonette, and to do anything not allowed by the original planning permission for your house, such as where a planning condition restricts alterations. It says permitted development rights are restricted in designated areas, listed buildings and conservation areas and areas of outstanding natural beauty, and that a council may force you to put things right if you build without the necessary permission. The Order can be amended, so check the current version and confirm with your council’s planning office before you build.

FAQs

Do I need planning permission for a conservatory in Northern Ireland?

Not necessarily. If it meets the Class A conditions it may be permitted development, but you must check the limits and any restrictions on your property, and confirm with the council.

Is a conservatory covered by the same rules as an extension?

The 2015 Order deals with conservatories within Class A, as its reference to materials used in the construction of a conservatory shows. Check with your council how it applies to your design.

Do building regulations also apply?

Permitted development concerns planning permission only. nidirect lists building regulations separately, so ask your council’s building control about them.

Bottom line

In Northern Ireland, a conservatory can be permitted development under Class A of the 2015 Order if it stays within the limits on curtilage coverage, height, rear projection and distance from boundaries, with tighter rules in conservation areas and other designated land, and planning permission needed to extend a flat or maisonette. Confirm your case with your council before you commit. This is general information, not planning advice.

Storm damage to a conservatory is generally covered under a standard home insurance policy, but how quickly and smoothly a claim goes depends heavily on what you do — and don’t do — in the first few hours and days.

Storm damage is generally covered as standard

The Association of British Insurers (ABI), the trade body representing UK insurers, confirms that damage caused by storms and flooding is covered by most standard home insurance and commercial business policies. This means a conservatory roof torn or cracked by wind, or damage from a fallen branch during a storm, is the kind of event standard cover is specifically designed to respond to — it isn’t generally something requiring specialist add-on cover, unlike some other risks.

Contact your insurer first, before arranging repairs yourself

ABI guidance is direct that the first step after storm damage is to contact your insurer as soon as possible, who will guide you on next steps, clean-up, and the information needed to progress the claim. Where the damage genuinely needs urgent, emergency repair — for example to stop water getting into the rest of the house through a damaged conservatory roof — the ABI advises speaking to your insurer first if at all possible, and if you do need to act before reaching them, to keep every receipt, since this becomes part of the claim.

Don’t throw away damaged items before they’re assessed

ABI guidance specifically advises against rushing to dispose of damaged items unless they pose a danger to health, because items that look ruined may still be repairable or restorable, and a loss adjuster or insurer will generally want to see, or be told about, the actual damage rather than working from a description alone. For a damaged conservatory specifically, this can mean leaving broken glazing panels, damaged furniture or a cracked roof panel in place (where it’s safe to do so) until the insurer has confirmed what they need documented.

What happens once a claim is open: the loss adjuster’s role

ABI guidance explains that a loss adjuster is typically appointed to assess the claim, carrying out an initial assessment of the damage, explaining the repair process, and setting out the options for alternative accommodation if needed. If a conservatory forms part of a home that’s otherwise uninhabitable during repairs, ABI guidance confirms the insurer will arrange and pay for temporary accommodation in line with the policy — though for a self-contained conservatory that doesn’t affect the habitability of the rest of the house, this specific provision is less likely to be relevant.

What standard storm cover generally doesn’t extend to

Storm and weather damage cover is generally about sudden, identifiable events — a specific storm causing specific damage — rather than gradual deterioration. A conservatory roof that’s been slowly failing due to age, wear or a lack of maintenance, rather than a single identifiable storm event, is a different kind of claim, and insurers commonly distinguish between the two when assessing what’s covered. Keeping basic maintenance up to date, and being able to point to a specific storm date and event if you do need to claim, both support a cleaner claims process.

FAQs

Do I need to report storm damage immediately, or can it wait?

Contacting your insurer as soon as possible is the ABI’s own advice — delaying can complicate a claim, particularly if further damage occurs in the meantime or if there’s any question about exactly when the damage happened.

Will my premium automatically go up after a storm damage claim?

It can, since a claims history is one of the factors insurers weigh when calculating premiums, though a single weather-related claim is generally treated differently from claims linked to an ongoing risk — checking with your specific insurer is the only way to know how it will affect your renewal.

Does it matter if the conservatory was added after the policy started?

Yes — insurers generally need to be told about significant additions like a conservatory so the buildings sum insured and cover reflect the property as it now stands; an unreported conservatory could complicate a claim relating to it.

Most roof-mounted solar installations, including on a conservatory, fall under permitted development in England — but the specific size and position conditions, and whether the roof can actually take the weight, both need checking separately.

When permitted development covers a solar installation

The Planning Portal’s official guidance confirms that in the majority of cases, installing solar PV doesn’t require a separate planning application, and this generally extends to panels mounted on a conservatory roof as much as on a main house roof. The guidance sets specific physical limits for this to apply: on a pitched roof, panels shouldn’t be installed above the highest part of the roof (excluding the chimney) and shouldn’t project more than 200mm from the roof slope; on a flat roof, the highest part of the equipment can’t be more than 600mm higher than the highest part of the roof.

Conservation areas, listed buildings and scheduled monuments

The Planning Portal guidance sets out specific restrictions for protected sites: panels must not be installed on a building within the grounds of a listed building, or on a site designated as a scheduled monument, regardless of the general permitted development allowance. In conservation areas or World Heritage Sites, panels cannot be fitted to a wall or roof enclosure that fronts a highway — a restriction specifically aimed at protecting street-facing appearance in these more tightly controlled areas, which can be directly relevant to a conservatory built at the front or side of a property rather than the rear.

The structural question that planning permission doesn’t answer

Even where an installation clearly qualifies as permitted development, that says nothing about whether the specific conservatory roof can actually carry the additional weight of solar panels and their mounting frames. A conservatory roof, particularly an older polycarbonate or lightweight glass roof, is often designed around a much lighter loading than a house’s main tiled roof, and wasn’t necessarily specified with solar panel loading in mind at all — this is a structural engineering question, entirely separate from whether planning permission is needed, and it needs answering before any installation decision, not after.

Building regulations and the electrical connection

Beyond the roof’s ability to bear the load, a solar PV installation involves electrical work that needs to meet building regulations requirements, typically carried out or signed off by a certified installer under a competent person scheme, covering the connection into the property’s electrical system safely. Where the conservatory roof itself needs structural reinforcement to take the panels, that reinforcement work may separately trigger building regulations requirements around the roof structure itself, on top of the electrical certification for the panels.

Questions worth putting to a solar installer considering a conservatory roof

Before proceeding, it’s worth asking an installer directly whether they’ve assessed the specific roof’s load-bearing capacity, whether the existing roof structure (glazing bars, ridge and supporting frame) is rated for the additional weight or would need strengthening first, and whether the panel positioning keeps within the permitted development limits on height and projection covered above rather than assuming it does. A reputable installer should be able to answer all three without hesitation, rather than treating the conservatory roof as no different from a standard tiled roof.

FAQs

Do I need planning permission for solar panels on a rear conservatory?

In most cases, no — rear-facing conservatory roofs generally fall under the same permitted development allowance as the main house roof, provided the size and position conditions are met, though it’s still worth confirming with your council if there’s any doubt, particularly in a conservation area.

Can any conservatory roof structurally take solar panels?

Not necessarily — many lightweight polycarbonate or glass conservatory roofs weren’t designed for this additional loading, so a structural assessment specific to your roof is essential before assuming it’s straightforward.

Does a solar installation on a conservatory affect Building Regulations compliance for the conservatory itself?

It can, particularly if the roof needs reinforcement to take the panel loading — this is worth raising directly with a structural engineer or your installer rather than assuming the two projects are entirely separate.

The choice between an unsecured homeowner loan and a secured second charge mortgage for funding a conservatory ultimately comes down to how much you need to borrow, and how comfortable you are putting your home behind that borrowing.

The basic split: unsecured borrowing vs borrowing secured on your home

An unsecured personal loan or homeowner loan for a conservatory isn’t tied to your property as security, meaning the lender can’t repossess your home directly if repayments are missed, though missed payments still damage your credit file and can lead to debt recovery action. A second charge mortgage, by contrast, is secured against your property in addition to your existing (first charge) mortgage, which generally allows for larger loan amounts and potentially lower interest rates than unsecured borrowing, but at the cost of your home itself being at risk if repayments aren’t kept up.

What a second charge mortgage actually is

MoneyHelper’s guidance describes a second charge mortgage as a loan secured on your property taken from a lender other than your main mortgage provider, sitting behind your existing mortgage in priority. It’s commonly considered specifically where your existing mortgage lender won’t lend you more under your current arrangement, or where you don’t want to remortgage and lose a good existing interest rate by increasing your borrowing through your main mortgage instead.

The real cost and risk trade-off

MoneyHelper’s guidance is direct that the interest rate on a second charge mortgage is often higher than your existing first mortgage rate, but is typically still lower than the rates you’d find on an unsecured personal loan or on credit cards — reflecting that the lender has property security behind the loan. The trade-off is equally direct: because it’s secured against your home, MoneyHelper’s guidance warns that you could lose your home if you don’t keep up the repayments, a consequence that simply doesn’t apply in the same way to an unsecured loan.

A further advance from your existing lender, as a third option

Rather than taking out a completely separate second charge mortgage, some homeowners are able to borrow more from their existing mortgage lender directly, known as a further advance — effectively increasing the size of your existing mortgage rather than adding a second, separate secured loan behind it. Whether this is available, and on what terms, depends on your existing lender’s criteria and how much equity you have in the property, so it’s worth asking your current lender what they’d offer before assuming a second charge mortgage with a new lender is the only secured option.

Questions worth asking before you borrow for a conservatory specifically

Given a conservatory sits at the lower end of home extension costs, it’s worth genuinely questioning whether the loan amount needed justifies putting your home at risk through secured borrowing at all, versus a smaller unsecured loan, savings, or simply scaling back the specification. Comparing the total cost of borrowing — not just the headline interest rate, but arrangement fees, valuation fees and any early repayment charges — across at least an unsecured option and a secured option gives a genuinely comparable picture before committing to either route.

FAQs

Is a second charge mortgage the same as remortgaging?

No — remortgaging replaces your existing mortgage with a new one (potentially with a new lender), while a second charge mortgage sits alongside your existing mortgage as a separate, additional loan secured on the same property.

Can I get a second charge mortgage with bad credit?

It’s generally more difficult and more expensive, since second charge lenders assess affordability and credit history similarly to other secured lending, though some specialist lenders focus specifically on this market — comparing terms carefully matters even more in this situation.

Is an unsecured loan always cheaper overall for a conservatory-sized project?

Not necessarily in interest rate terms, since secured lending often has a lower rate, but an unsecured loan avoids putting your home directly at risk and often has simpler, faster approval — which one is genuinely cheaper depends on the loan amount, your credit profile and the specific rates on offer.

A conservatory and a loft conversion solve different space problems at very different price points — comparing them on cost alone misses that they usually aren’t actually interchangeable options for the same need.

The headline cost difference

A conservatory generally carries what’s often described as the smallest price tag among common home extension options, while a loft conversion for a typical 30 square metre space runs considerably higher — commonly quoted at roughly £22,500 to £30,000 for a simpler Velux (roof-light) conversion, £40,000 to £60,000 for a dormer conversion, and £60,000 to £85,000 or more for a full mansard conversion, depending on the property and specification. That gap alone explains why a conservatory is often the first extra-space option homeowners consider, even before weighing up what each option actually adds.

What each option typically adds to your home’s value

Industry guidance on loft conversions commonly cites a value uplift in the region of 15% to 25% for a well-executed conversion, with the strongest returns generally coming from conversions that add a genuine bedroom, particularly with an en-suite — on a higher-value property, this can translate into a value increase well above the conversion’s own cost. A conservatory is also generally considered value-adding, but it isn’t usually counted as adding a bedroom or as significantly increasing a property’s official habitable floor area in the way a loft conversion can, which is part of why the value comparison tends to favour the loft conversion despite its higher upfront cost.

Comfort and year-round usability aren’t the same either

A loft conversion, built to full building regulations with proper insulation, heating and often an en-suite, functions as genuine year-round living space in the same way as any other room in the house. A conservatory, unless built to a higher specification with proper insulation and glazing, can struggle with extremes — uncomfortably hot in direct summer sun and difficult to heat economically in winter — which is a genuine practical trade-off against its lower upfront cost, and one worth weighing against how the extra space will actually be used through the year.

Regulatory process and how long each one actually takes

Conservatories in the UK are frequently built under permitted development, without a full planning application, and because of their lighter-weight construction can often be completed within days to a few weeks once work starts. A loft conversion typically involves full building regulations approval regardless of its planning status, structural work to strengthen the floor and roof, and a considerably longer build programme, commonly running to several weeks or a small number of months depending on the conversion type and complexity.

Working out which one actually fits the need

The practical way to choose isn’t simply comparing headline costs, but working backward from what the space is actually for: a bright, semi-outdoor-feeling room for dining or relaxing generally points toward a conservatory, while a genuine extra bedroom, home office used daily year-round, or a space intended to be indistinguishable from the rest of the house points toward a loft conversion, budget allowing. For some properties, a loft conversion simply isn’t feasible — limited roof height, planning constraints, or an already-converted loft — in which case the comparison resolves itself regardless of value calculations.

FAQs

Can I add both a conservatory and a loft conversion?

Yes, there’s no rule against doing both, and many homeowners do exactly this over time — they solve different space problems, so combining them isn’t redundant in the way choosing between two similar extensions might be.

Does a conservatory count toward a property’s official floor area on paper?

This depends on how it’s built and recorded, but a standard lightweight conservatory is often not counted the same way as fully insulated, permanent living space — a factor worth checking with a local estate agent if maximising formal floor area is part of the goal.

Is a loft conversion always possible?

No — roof height, the type of roof structure, and existing loft use (such as an already-converted space or one housing a water tank that’s expensive to relocate) can all rule it out or add significant cost, which is why a feasibility check from a specialist is worth doing before comparing costs in detail.
