You do not need to apply for planning permission for repairs, maintenance or minor improvements, such as painting your house.
If you live in a listed building, you will need listed building consent for any significant works whether internal or external.
If you live in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Broads, you will need to apply for planning permission before cladding the outside of your house with stone, tiles, artificial stone, plastic or timber.
Outside these areas, cladding may be carried out without having to first apply for planning permission provided the materials are of a similar appearance to those used in the construction of the house.
