Not all extensions, new buildings or changes of use require planning permission.

Planning legislation specifies types of development which can be carried out as permitted development without our planning approval.

The most common of these permitted development rights relate to extensions and alterations to dwelling houses, although they also apply to retail, industrial and other types of development. They also allow certain changes of use.

The legislation around this can be very complicated so for advice, take a look at the Planning Portal website section on permissions for the most up to date information.

Permitted development rights are restricted for buildings in conservation areas. Many of those restrictions are applied across the country and are set out on the Planning Portal. However, further restrictions are also applied through Article 4 Directions within many of our conservation areas.

Most extensions and external alterations to listed buildings together with many internal alterations require planning permission. You should always speak to us before undertaking any works to a listed building.
