Listed Building Consent Explained: Renovating a Protected Property

Listed building consent protects buildings of special architectural or historic interest. London has thousands of listed buildings, from grand Georgian terraces to modest Victorian cottages. If your home is one of them, almost any change beyond like for like repair needs consent, and that applies inside as much as outside.

What listing covers

Buildings are listed at Grade I, Grade II* or Grade II, with the great majority at Grade II. Whatever the grade, the listing covers the whole building, inside and out, along with fixtures attached to it and, in many cases, older structures within its grounds. The listing description is a guide, not a complete inventory, so a feature not mentioned may still be protected.

Work that usually needs consent

• Extensions, loft conversions and changes to the roof
• Removing or moving internal walls, chimney breasts or original doors
• Replacing windows, doors, floors, staircases or plasterwork
• New bathrooms and kitchens where they affect historic fabric
• Repointing or cleaning brickwork in a different way or with different materials
• Painting or rendering previously bare brick

Genuine like for like repairs using matching materials and methods may not need consent, but always confirm with the council’s conservation officer first.

How to apply

1. Understand the building: a heritage statement explains its significance and how your proposal affects it.
2. Seek pre application advice from the conservation officer, which is strongly recommended.
3. Submit detailed drawings, specifications and the heritage statement. There is no fee for listed building consent itself.
4. Allow time: the target is eight weeks, and Grade I and II* proposals involve Historic England.
5. If the work also needs planning permission, the two applications are usually submitted together.

Why it matters

Unauthorised work to a listed building is a criminal offence, and the council can require it to be reversed at the owner’s cost, even if a previous owner carried it out. Buyers’ solicitors look for consents, so proper approval protects the value of your home.

The right approach on site

Listed buildings reward a careful, traditional approach: lime mortars rather than cement, repair before replacement, breathable materials and joinery matched by hand. The craftsmanship involved is as important as the paperwork.

How we handle listed buildings on London’s Prestige projects

We work with your architect or heritage consultant and the conservation officer, follow approved details precisely, and use traditional materials and methods where the building needs them. Your project manager keeps a clear record of what has been approved and what has been done, so the consents and the finished work match.
