If your property is listed or in a conservation area, you will need to apply for planning permission for certain types of work which do not otherwise need an application. Check with your local planning office at the outset. A listed building will also need Listed Building Consent for any work, inside or out, that affects its character or setting. Altering a listed building without consent is a criminal offence, so seek professional advice from an architect, surveyor or builder specialising in old buildings and consult your local planning or conservation officer before making any plans.
If you live in England and Wales, your local council’s Building Control department will tell you whether you need Building Regulations approval and how to apply.
