Listed building consent explained

What listed building consent is

Listed building consent (LBC) is a separate approval system for works to listed buildings.¹ It protects buildings of special architectural or historic interest from harmful alterations.

There are three listing grades in England and Wales:

• Grade I: Buildings of exceptional interest (2.5% of listed buildings)
• Grade II*: Particularly important buildings of more than special interest (5.8%)
• Grade II: Buildings of national importance and special interest (91.7%)

Scotland uses A, B, and C categories. Northern Ireland uses A, B+, B1, and B2.

When you need listed building consent

You need listed building consent for any work that affects the character of a listed building.² This includes:

• External alterations (windows, doors, roofs, walls, render)
• Internal alterations (removing walls, altering staircases, changing room layouts)
• Demolition of part or all of the building
• Alterations to fixtures and fittings (fireplaces, panelling, plasterwork)
• Extensions or outbuildings within the curtilage

Minor repairs using matching materials may not need consent, but check with your conservation officer first. Replacing like-for-like (e.g., one slate tile with another matching slate) is usually exempt.

Difference from planning permission

Planning permission controls land use and external appearance from a planning perspective. Listed building consent protects the special historic interest of the building itself.

You often need both. For example, building an extension to a listed house requires planning permission (is the extension acceptable?) and listed building consent (does it harm the listed building?).

Permitted development rights do not apply to listed buildings. All external alterations need consent, even if they would be permitted development on an unlisted house.

How to apply

Listed building consent applications are submitted to your local planning authority via the Planning Portal. You need:

• Existing and proposed plans and elevations
• Heritage statement (explaining how the work affects the building's significance)
• Schedule of works and materials
• Photographs of affected areas

There is no fee for listed building consent applications in England, Wales, or Scotland. Northern Ireland charges a fee.

Decision time is 8 weeks for minor works, 13 weeks for major schemes. Listed building consent can take longer if Historic England is consulted (required for Grade I and II* buildings).

Enforcement and penalties

Carrying out works to a listed building without consent is a criminal offence.³ On conviction, you face an unlimited fine and up to two years imprisonment for deliberate damage.

The council can serve a listed building enforcement notice requiring you to undo the work. There is no time limit for enforcement on listed buildings (unlike planning permission, which has a 4-year limit).
