Permissions to carry out works to a listed building

It is a criminal offence to carry out works to a listed building without prior listed building consent - even if you did not know that the building was listed.

There are two types of permissions:

  • Certificate of Lawfulness of Proposed Works to a Listed Building - if the proposed works will not affect the character of the listed building, you may apply for a lawfulness certificate.
  • Listed Building Consent - you will need Listed Building Consent for any alteration or extension that will affect the character of a listed building or if you wish to demolish a listed building.

If you are not sure which type of permission to apply for, seek advice with the Royal Borough.
