Many householder projects such as extensions, garage and loft conversions are considered to be permitted development and do not require planning permission. However, this depends on the size and scale of the proposed work and does not apply to flats, maisonettes or other buildings.
The Planning Portal provides more information on the rules around permitted development or you can read the guidance notes on permitted development for further information:
- Household permitted development advice note
- Permitted development for householders – Technical guidance from Communities and Local Government
In most cases, it's easy to know if a proposed project qualifies as permitted development but there may be instances where the decision is less clear. In these cases, it's possible to alter your plans to ensure they meet permitted development rules.
You can also apply for a Lawful Development Certificate, even if you're sure your project is permitted development. This gives you proof that your household building work is lawful and may help if you later want to sell your property as it answers any questions raised by potential buyers.
Remember, even if you're project falls under permitted development and doesn't need planning permission, you'll still need to comply with building regulations.
Rules in conservation areas
If you live in a conservation area, we may have removed some permitted development rights under an Article 4 direction. These are made when the character of an area of acknowledged importance would be threatened.
If your property is affected by an Article 4 direction, you will need planning permission. Please check with us first before carrying out any alterations as your property won’t be covered under permitted development.
