Do I Need Planning Permission? - Free Permitted Development Checker

PRAITE helps UK homeowners check if their home improvement projects need planning permission or qualify as permitted development under GPDO rules.

What is Permitted Development?

Permitted development rights allow you to make certain improvements to your home without applying for planning permission. These rights are set out in the General Permitted Development Order (GPDO) 2015.

Loft Conversions - Dormers and roof enlargements
Outbuildings - Sheds, garden rooms, summer houses
