Permitted Development Rights
Permitted Development Rights are national planning allowances that grant automatic planning permission for certain types of development, meaning works can be carried out without submitting a full planning application, provided specific limits and conditions are met. Even under permitted development, speak with a consultant to confirm whether flood risk obligations still apply. Permitted development rules are published on GOV.UK planning permission overview.

Case Example
A homeowner extends their semi-detached house by 3 metres to the rear, allowing it to proceed under Class A Permitted Development without a full planning application.
Check flood constraints. Rida Reports confirms if an FRA is still required.
