Do You Need Planning Permission in Leeds?

No. Many single-storey rear extensions fall under permitted development and need no planning application, as long as they stay within size, height and boundary limits and the property isn't restricted. It's always subject to conditions, so we recommend confirming with Leeds City Council.

Permitted development rights allow certain building work — such as many modest single-storey rear extensions and some loft conversions — without a full planning application, provided strict criteria are met. Exceeding those limits, or being in a conservation area, means a full application is usually required.

You'll generally need full planning permission for double-storey extensions, extensions to the front of the house, larger projects that exceed permitted development limits, or work on flats, listed buildings and conservation areas. We'll tell you which applies to your project.

Planning permission is about whether you're allowed to build; Building Regulations govern how it must be built for safety and standards. Building Regulations apply to almost all extensions even when planning permission isn't needed, and we coordinate both.

Yes. We provide planning support, prepare the drawings and can manage the application process, so whether your project is permitted development or needs full planning, one experienced team handles it end to end.

Because rules vary by property and location, the definitive answer comes from Leeds City Council — you can also apply for a Lawful Development Certificate to confirm permitted development. We'll help you check your specifics as part of a free, no-obligation consultation.
