Planning and Listed Building Consents

Most external alterations, extensions and changes of use require planning permission.

Particular care is required in conservation areas. You should ensure that you have the necessary consents before you start work, as planning enforcement action can be taken even if you have obtained Building Regulation approval.

For a Listed Building consent is also required for all internal and external works, including those affecting non-original parts of the building. You should note that unauthorised work to a Listed Building is a criminal offence.

Building Control Surveyors act as the eyes and ears of the planning officers on site. We ensure that buildings are constructed in accordance with the conditions of Planning Permissions and Listed Building Consents, and advise the planners at an early stage if things are going wrong.
