You must apply for full planning permission for any alteration to your shopfront that would change the shop's appearance. This includes replacement shopfronts, installation or replacement or new entrance doors and windows and external security measures.
Small alterations to your shop front may not need planning permission, but the alterations must not materially change the outward appearance of the property.
If the shop is a listed building (or part of), you must apply for listed building consent for any internal or external alterations.
If the alterations to your shop front include adding or changing an advertisement or sign, you may also need to apply for advertisement consent. This includes lettering on an awning or blind. Please see the advertisements and signs section for further guidance.
