Flood Risk Activity Exemptions
Do you need a flood risk activity exemption?
If you want to carry out certain types of works in, over, under or near a main river, or flood defence (including a sea defence), or within a flood plain you may be eligible to register for a flood risk activity exemption depending upon the type of activity you wish to carry out rather than be required to apply for a permit.
In order to register an exempt flood risk activity you must read and understand the appropriate guidance below.
Flood Risk Activity Exemptions
You can register an exemption for the following activities free of charge. The guidance document at the bottom of the page provides additional information and conditions that must be met in order to register for an exemption. Failure to meet these requirements could lead to enforcement action as it is a criminal offence to carry out an exempt activity without meeting the appropriate conditions.
Before registering for any exemption if you think you will need to undertake temporary works (for example use scaffolding or coffer dams in the channel), you should contact your local NRW office to discuss if a bespoke permit might be needed.
