Frequently asked questions

When do you need planning permission for a house extension?
Single-storey rear extensions up to 4m (detached) or 3m (semi-detached / terraced) are usually permitted development. Two-storey extensions, anything in a conservation area, or larger projects almost always need a planning application.
What's the difference between planning permission and permitted development?
Permitted development rights let you build certain things without applying for planning permission, subject to specified limits. Anything outside those limits — taller, larger, in a protected area — needs full planning permission.
How long does a householder application take?
The statutory target is 8 weeks from validation. Most simple householder extensions are decided within that window; complex or contested cases (especially with objections) can take longer.
Can I get email alerts for extensions planning applications anywhere in the UK?
Yes. Click the "Set up alerts" button on this page and you'll get a daily (or weekly) email listing every new extensions application submitted anywhere in the UK. No need to pick a postcode or draw a map - pick the category once, choose your frequency, and we'll do the rest.
