Listed building consent in Bath: what to expect

When do I need listed building consent?

You need listed building consent for any work that affects the character of a listed building as a building of special architectural or historic interest. That covers the inside as well as the outside, and the whole building, not just the parts mentioned in the listing description. Replacing windows, removing or moving internal walls, changing fireplaces, joinery or staircases, and some repairs all usually need consent.

What happens if work is done without consent?

Carrying out work to a listed building without consent is a criminal offence, and the council can require it to be put back. Liability can pass to a new owner, so unauthorised work often comes to light when a house is sold. If you have bought a listed house and are unsure about earlier work, it is worth getting advice before you plan anything new.

What a good application includes

Accurate measured drawings of the existing building, drawings of what is proposed, and a heritage statement that explains the building's significance and how the work affects it. For windows, joinery and stone repairs, the conservation officer will usually want large-scale details showing sections, materials and methods, for example lime mortar mixes and stone replacement.

How long does it take?

The council aims to decide listed building consent applications within 8 weeks of validation. Planning permission is often needed alongside it, and the two are usually submitted together. There is no application fee for listed building consent on its own.

Common pitfalls in Bath

Replacement windows: double glazing in historic sashes is judged case by case, so a survey of the existing windows and a careful proposal matter. Stone repairs: cement mortar and the wrong stone can damage Bath stone, so lime and matching stone are expected. Internal changes: removing walls, chimney breasts or historic joinery is often resisted, so plan the layout around what is significant.

Getting help

We have spent most of our working lives on listed buildings, and prepare surveys, heritage statements, drawings and details in house. A short conversation at the start often saves months later.
