In Bath, a building's listing covers the inside as well as its honey coloured stone front. That surprises many owners, and it means that plenty of ordinary jobs like moving a kitchen, taking out a partition or adding insulation can need formal consent. Here is how to tell which internal works need consent, and how to handle the process with Bath & North East Somerset Council.
When a building is listed, the protection covers the whole building, inside and out, whatever its grade. It also covers fixtures attached to it and, in many cases, structures within its curtilage that were there before July 1948. Bath has thousands of listed buildings, most of them Grade II Georgian townhouses and terraces, and the whole city is a World Heritage Site, so the Council looks closely at historic interiors.
Many owners get caught out by the list entry itself. The description on the National Heritage List often only mentions the façade, but that does not mean the interior is unprotected. Original plan form, staircases, joinery and plasterwork all count, even if the entry never mentions them. The test is whether the work affects the building's character as a building of special architectural or historic interest.
In a typical Bath townhouse, the jobs below almost always need listed building consent:
Like for like repairs using matching materials and methods do not normally need consent. That covers patching lime plaster with lime, repairing sash windows, or replacing a few decayed floorboards with matching timber. Redecorating modern surfaces is usually fine, and so is swapping modern kitchen units or bathroom fittings in the same position, as long as no historic fabric is disturbed.
Grey areas are common. Painting over original graining, sanding historic floors, or rewiring that means chasing into old plaster can all count as alterations. If you are not sure, ask the B&NES conservation team before you start. For extra certainty you can apply for a Certificate of Lawfulness of Proposed Works, which confirms that a specific job does not need consent.
Listed building consent applications go to Bath & North East Somerset Council, usually through the Planning Portal. You don't pay an application fee for listed building consent on its own, although you will if you also need planning permission. The Council aims to decide within eight weeks, but complex schemes in central Bath can take longer, especially if they ask for changes.
A good application includes existing and proposed drawings, photographs of the affected rooms, and a heritage statement explaining what is significant and how your proposal respects it. Depending on the size of the job, professional fees for surveys, drawings and a heritage statement often come to somewhere between £1,000 and £4,000. Paying for the Council's pre-application advice service on larger schemes can save time and abortive design work.
Carrying out unauthorised works to a listed building is a criminal offence. The penalty can be an unlimited fine or imprisonment, and it applies to the owner and to whoever does the work. B&NES can also serve an enforcement notice requiring the work to be reversed at your cost, and there is no time limit on enforcement.
Unauthorised alterations often surface when you sell, when a buyer's solicitor asks for consents for past works. In Bath that can delay a sale or knock value off the price. Retrospective consent is possible but never guaranteed, so it is far cheaper to get the paperwork right before any walls come down.
Usually not if you are swapping modern units in the same place without disturbing historic walls, floors or joinery. Consent is likely if you move the kitchen, remove walls, or need new service runs through original fabric.
The statutory target is eight weeks from a valid application. Allow longer for complex schemes or if the conservation officer asks for amendments, and build that into your project programme.
No. Work must not start until consent is granted and any conditions requiring approval of details have been discharged, and both the owner and the contractor can be liable if it does.
