PD Rights

Following the Government’s announcement of the change to Permitted Development (PD) rights, lots of myths have been circulating in the media that it is now a free for all which is not the case. The legislation comes on the back of the Coronavirus Bill and is an essential component in creating healthy and safe environments for people to live in.

To separate fact from fiction, we give an outline of each new PD right, along with links to the full order so you can see what the new legislation entails. Ultimately the local authority planning departments will still have plenty of control over proposals.
