Not all work requires planning permission as ‘Permitted Development’ allows certain work to be carried out without requiring prior permission. You can find out about what the permitted development rules are by looking at the guidance available on both the Planning Portal Website and Government website.
We can only answer questions about whether planning permission is required through a formal application for a certificate of lawful development, which will give you a legally binding decision as to whether or not your proposal requires planning permission. You can read more about lawful development certificates on the Planning Portal Website
You do not have to obtain a certificate of lawful development if your proposal is permitted development, but it can be advisable to do so.
If you live in a listed building, listed building consent is another permission that may be required (it can be required where planning permission is not needed, or it can be required in addition to planning permission). Please email planning@rutland.gov.uk with details of your proposal and address if you wish to check if you will need listed building consent. Listed building consent is generally required for any alterations to the historic fabric (the elements that characterise the structure of the building such as walls, roofs, internal surfaces, floors, stairs, landings and all doors and windows) of the building.
