Flood Risk Activity exclusion

What is a flood risk activity exclusion?


If you want to carry out works in, over, under or near a main river, a flood defence (including a sea defence)or within a flood plain, you may be eligible for a flood risk activity exclusion depending upon the type of activity you wish to carry out.

To establish whether your flood risk activity can be considered as an exclusion, you must read and understand the appropriate guidance below. 

Flood Risk Activity Exclusions

You may carry out the following activities free of charge without the need to register with us as long as certain conditions are met. The guidance document at the bottom of the page provides the specific conditions that must be met when undertaking the activity. Failure to meet these requirements could lead to enforcement action as it is a criminal offence to carry out an excluded activity without meeting the appropriate conditions.

Before undertaking an excluded activity, you should consider if there is any need to undertake temporary works (for example use scaffolding or coffer dams in the channel). If temporary works are required, you should contact your local NRW office to discuss if a bespoke permit might be needed to undertake the activity.
