Some works to residential properties do not require planning permission and can be carried out under Permitted Development (PD) regulations.
For general advice about whether specific works to a house require planning permission, then please use the Planning Portal's Interactive House to check.
Just choose the part of the house you are thinking of changing and the relevant PD rules will be explained.
Restrictions on Permitted Development Rights
Please note that the permitted development rights which apply to many common projects for houses do not apply to flats or maisonettes.
Also, some properties will have had their PD rights removed, in which case, no development can be done without submitting an application.
In some areas of the district, permitted development rights are more restricted. If you live in a Conservation Area you will need to apply for planning permission for certain types of work which would not normally need an application in other areas of the district. If your proposal affects a Listed Building, it will be necessary to obtain Listed Building Consent before undertaking any work. To find out if your property still has its PD rights, email firstname.lastname@example.org It may be that an officer will have to look into the history of the site in order to answer this question, so it is unlikely to be something that can be easily dealt with over the telephone.
Is the work you wish to carry out Permitted Development?
Planning Officers can only advise informally whether specific proposals might require planning permission. If you would like written confirmation from us that you do not need planning permission you need to apply for a Certificate of Lawfulness. There are two different forms depending on whether you have done the work or would like to. If you have not already done the work, choose the Certificate of Lawfulness (Proposed) forms. If you have already done the work you need Certificate of Lawfulness (Existing) forms.
Having such a Certificate can be particularly useful if you wish to sell your house in the future, as it provides written proof that work you have done to your house did not require planning permission.

Please be aware that Building Control and Planning are two separate processes, and whilst Planning Permission may not be required for certain works, you may still be required to obtain Complying with Building Regulations
