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.
