Do I Need Planning Permission? The Simple UK Guide for Homeowners

If you’re thinking of extending your home, converting your loft, or transforming your garage, one of the first questions you might ask is:

“Do I need planning permission?”

The answer depends on a few key factors. Let’s simplify it.


What is Planning Permission?

Planning permission is official approval from your local council that allows you to carry out certain types of building work. It ensures that developments are safe, suitable, and in keeping with local policy.


When You Don’t Usually Need It: Permitted Development

Some projects can be done without full planning permission under rules called Permitted Development Rights. These cover minor changes such as:

  • Small rear or side extensions

  • Loft conversions with dormers (within limits)

  • Garage conversions (internal only)

  • Porches, sheds, and outbuildings

  • Rooflights or skylights

Key point: Your property must meet certain criteria (e.g., not in a conservation area, not previously extended beyond limits).


When You Do Need Planning Permission

You will likely need permission if your project:

  • Extends beyond the permitted size/height limits

  • Affects neighbours’ privacy or light

  • Is in a conservation area or listed building

  • Includes change of use (e.g., turning a garage into a separate dwelling)

  • Involves major structural alterations

It’s always safest to check with your local authority or consult a planning professional before starting.


What About Building Regulations?

Even if you don’t need planning permission, you will need Building Regulations Approval for most structural work to ensure the safety and compliance of the build.
