Listed building consent

Alterations to a listed building

If you own or live in a listed building, you will need listed building consent from your local council to make changes or alterations to it. This includes anything that may change the appearance, character, or layout of the building.

Depending on the changes, you may also require planning permission. If this is the case, please apply for both listed building consent and planning permission when making your application. 

It is a criminal offence to carry out works on listed properties without permission. Any changes made without consent will affect resale value. 

When you need listed building consent

Consent is required to make the following changes to any listed building:

  • internal or external alterations which affect the character
  • extensions
  • demolition of all or part of the building
  • minor repairs that affect the character - repairs of a like for like nature do not normally require consent

Some examples of works requiring consent

  • adding a rooflight
  • creating new openings in a wall or roof
  • removing or lowering a chimney
  • altering the boundary wall
  • adding a satellite dish or solar panels
  • painting or rendering stonework
  • creating flue openings
  • building decking
  • adding external pipework
  • removal of internal stud walls
  • removal or alteration of staircase
  • alteration or removal of internal decorative features (fire places and plaster work)
  • relocation of a kitchen or bathroom
  • removal of historic material such as ceilings or wood panelling
