Flood risk activity exemptions
Find out if you need to register a flood risk activity exemption
You can register an exemption if you meet the specific conditions set out in the technical guidance for flood risk activity exemptions. It is a criminal offence to carry out an exempt activity without meeting the appropriate conditions. It must be noted that works in close proximity to a designated site may not meet the exemption criteria.
It is free to register an exemption.
Exempt flood risk activities:
- the erection of an electrical cable service crossing over a main river
- the erection of a service crossing below the bed of a main river by directional drilling not involving an open cut technique
- service crossings attached to the outside of existing structures over a main river
- the construction of footbridges
- the maintenance of raised river or sea defences
- the maintenance of structures within the channel of a main river other than raised river or sea defences
- the construction of a drinking bay on the bank of a main river
