Check if you need planning permission
Many householder projects such as extensions, garage and loft conversions may not need planning permission. It all depends on the size and scale of the work.
Permitted development does not apply to flats, maisonettes or other buildings.
You can find out more about permitted development rules on the Planning Portal. Or read the guidance notes below:
- 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 work falls under permitted development. For cases that are less clear, you can alter your plans to meet the permitted development rules.
If you are sure that your project does fall under permitted development you can apply for a lawful development certificate. This gives you proof that your building work is lawful and may help if you later sell your property.
Remember, even if your 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. We do this if 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.
