Questions

If yours isn't here, email us and we'll reply within one working day.

How do I know if I need planning permission at all?

Many extensions and loft conversions are permitted development and need only a lawful development certificate or a prior approval. Tell us your project and we'll check which route applies before we start. The price is the same either way.

Who pays the council's planning fee?

You do, direct to the council when the application is submitted. In England a householder application is currently £548 and a lawful development certificate for a proposed project is £274. Our guide shows you the exact fee for your project before you pay it.

Do you submit the application for me?

No, you submit it yourself on the Planning Portal, which takes about 30 minutes. With your drawings you get a step-by-step guide and your answer to every question on the form, so it's mostly copying and uploading. If you get stuck, email us and we'll help.

What happens if the council asks for changes?

The planning officer will contact you, as the applicant. Forward the request to us and we'll update your drawings, usually within 3 working days, ready for you to send back. Officers often ask for small changes such as a lower roof or a different window. Every change the council asks for is included until your application is decided.

Can I change the design myself?

Yes. Two rounds of your own changes are included before you submit. If you want further changes of your own after submission, we'll tell you the cost before we make them.
