Some minor alterations and extensions can often be carried out without the need to apply for planning permission. This is known as 'permitted development'.
Permitted Development only relates to houses and bungalows and does not apply to flats, maisonettes, mobile homes or residential caravans.

If you are still not sure whether you need planning permission you can submit an application for a certificate of Lawfulness for a proposed use or development. You will receive a formal decision as to whether your proposal is permitted development or an application for planning permission is required.
Applications can be made online via the planning portal or paper copies obtained from the planning website or planning reception points.
Listed Building Consent
If you wish to undertake internal or external alterations which affect the character of a listed building or extend or demolish part or all of a listed building you will require listed building consent. Listed building consent may also be required for any works to buildings within the grounds of a listed building. It is a criminal offence to carry out works to a listed building without the necessary consent. To find out whether listed building consent is required for works relating to your premises you should submit a Listed Building Consent Enquiry Form.
Remember, whether or not your building project requires planning permission you will still need to comply with Building Regulations.
You can find more information and advice on Building Regulations on the Building Control pages or the Planning Portal.
