For a fee, you can ask us if your building works require planning permission. We cannot tell you over the phone. The way to ask is through an application for a Certificate of Lawfulness. This process takes around 8 weeks.
For a fee, we can also check if a specific proposal falls under permitted development rights or whether permitted development rights have been withdrawn on the property. Please see Planning Fees and Charges from April 2023.
What are permitted development rights? Toggle accordion
If you live in a house, in many cases you can carry out minor works without the need to apply for planning permission. These are known as ‘permitted development’ rights. They do not apply to flats or maisonettes.
How will I know if permitted development rights have been removed from my house? Toggle accordion
Always check the planning history of your property before undertaking any works. Permitted development rights might have been removed on the original planning permission for your house. These rights will also be affected if the property has already been extended.
For a fee, we can check if a specific proposal falls under permitted development rights or whether permitted development rights have been withdrawn on the property. We can also provide you with the recent planning history of your property. Please see Planning Advice and Enquiries Charges September 2022.
Permitted development rights can change depending on where you live. If you live in an Article 4 Direction Area, such as Fishpool Street, most of your permitted development rights will have been removed.
Alternatively, if you live in a relatively new property, such as the Napsbury, Jersey Farm or Hill End/Cell Barnes Lane developments, permitted development rights may have been removed by a planning condition.
