Do you need planning permission for a house extension or alteration?

Information on whether you need or don't need planning permission, is available on the Planning Portal website. Alternatively, please email planningenquiries@swindon.gov.uk

If you want to be certain that your proposal does not require planning permission or that the existing use of a building is lawful for planning purposes, you can apply for a 'Lawful Development Certificate' (LDC) on the Planning Portal website.

It is not compulsory to have an LDC but there may be times when you need one to confirm that the use, operation or activity named in it, is lawful for planning control purposes.

Do you need building regulations approval?

As well as getting planning permission you may need separate approval for a new building, extension or major alteration. The work needs to reach certain standards so that the building is safe and energy efficient.

See the Check if you need Building Regulations Approval webpage for further information.
