Permitted development is a general planning permission granted by national law, rather than a decision made about your specific property. It lets certain kinds of work go ahead without a planning application, provided the work stays within set limits.
What it can cover
- Single-storey rear extensions up to set size limits
- Some loft conversions, within volume and design limits
- Some outbuildings, and changes to roofs such as rooflights
- Certain changes of use, subject to their own rules
Where it typically does not apply, or is reduced
- Flats and maisonettes, which generally do not have the same permitted development rights as houses
- Listed buildings
- Conservation areas, where some rights are restricted
- Land where an Article 4 direction has removed specific permitted development rights
- Land in front of the property, facing a road
Conservation areas and Article 4 directions are common enough in London that they are worth checking early. We cover them in more detail in our guide to conservation areas and Article 4 directions.
Permitted development is not a free pass
Work carried out under permitted development still has to comply with Building Regulations, and it can still be affected by party wall rules if it is near a boundary. Many homeowners also apply for a Lawful Development Certificate, which is not compulsory but provides written proof that the work was lawful, which can matter when you come to sell.
This guide is general information for homes in England and is not legal or planning advice. Rules can change and differ between properties and local authorities, so always confirm the position with your council or a qualified professional.
