Planning permission guidance

You usually need planning permission to make a change to your business premises, including:

• extensions to a shop or office
• alterations to shop fronts
• installing external security shutters or grilles
• changes in the use of the land or buildings

If the property is a listed building (or part of), you must also apply for listed building consent. This is for any internal or external alterations.
