Do I need planning permission for a house extension in the UK?

Most small extensions fall under permitted development rights, meaning you may not need full planning permission. Larger projects or those in conservation areas will usually require approval from your local council.

What are permitted development rights for extensions?

Permitted development rights allow you to extend your home without applying for planning permission, provided certain size and height limits are met. Always check with your local planning authority to confirm before starting work.

How much does a house extension cost in the UK?

On average, a single-storey extension costs between £1,500–£2,500 per square metre. Prices vary depending on location, design, and the complexity of the build.

How long does a house extension take to build?

A straightforward single-storey extension may take 10–12 weeks to complete. More complex or multi-storey builds could take 4–6 months.

Can I live in my house while the extension is being built?

Yes, most people stay in their homes during the build, although there may be some disruption. Builders will often section off areas to keep the rest of the house habitable.
