You will need to apply for listed building consent before carrying out works to demolish, alter or extend a listed building or structure. This includes repairs and replacements and any alterations which affect the character of the listed building. Some minor repairs may be able to be undertaken without consent.
Listed building consent applies to:
- works to the interior or exterior of a building or structure
- any building or structure that is attached to the listed building
- some buildings within the grounds of a listed building (if they are curtilage listed)
- any other works which would affect the character of a building of special architectural or historic interest
You will also need planning permission for works to, or the erection of, any unlisted buildings or structures that are within the grounds of a listed building.
It is a criminal offence to carry out work to a listed building or structure without first getting consent. If you are the owner of a listed building you have a responsibility and duty to look after and maintain your property. The council can insist that owners of listed buildings carry out works to preserve the building.
