What planning permission do I need when buying windows?

Prior to buying any window you should check with your local planning authority if any approval is required i.e. if you live in a conservation area. The installation of new or replacement windows needs to be carried out by a competent certified tradesman i.e. a FENSA or CERTAS installer or it should be signed off by building control. You will require evidence that you have done this when you come to sell your home.
