Conservation and Listed Buildings FAQs

Listed Building Consent is required if carrying out changes to the exterior or interior of a Listed Building. It is a criminal offence to complete work on a Listed Building without consent from the local authority. This is because these buildings are of National importance.

Read more about when Listed Building Consent is required on the Historic England website, or contact our team, who can help with Listed Building applications and advice.

Listed Building Consents are submitted to local planning authorities, so it is recommended you seek the expertise of specialist conservation architects and suitably qualified planners with an expertise in heritage buildings. They have the experience and knowledge to ensure applications go smoothly and cover key requirements.

Suitably qualified experts can also liaise and consult authorities to find out if consent is required for the alterations you’re looking to make to the building before making an application.

Architects have a primary role in identifying the potential challenges of historic buildings, areas and places, including managing change in a sustainable manner. Architects find design solutions including the repair, maintenance, adaptation and re-use of historic buildings and places that sustains and promotes their cultural significance.

Suitably qualified planners and conservation architects can complete assessments of the site, prepare plans and assist with applications if a Listed Building Consent is required.

There are around 400,000 listed building entries in England. Listed buildings are classified into three grades:

  • Grade I buildings are of exceptional interest. Just 2.5% of listed buildings are Grade I.
  • Grade II* buildings are particularly important buildings of more than special interest. 5.8% of listed buildings are Grade II*.
  • Grade II buildings are of special interest warranting every effort to preserve them. Over 90% of all listed buildings are in this grade (ref. 3).

The special interest of a candidate building is assessed with the greatest care. The special interest may arise from the contribution the building makes to the architectural or historic interest of any group of buildings of which it forms part (group value). Many buildings are interesting architecturally or historically but to be listed a building must have special interest.
