The City of London Corporation works to ensure that the City stays at low risk from flooding.

We are the lead local authority with responsibility for the coordination of actions to address flood risk in the City.

Under the Flood and Water Management Act 2010, we are required to:

  • prepare a local flood risk management strategy
  • investigate and report on flooding incidents
  • maintain a register of flood prevention assets
  • act as "approving body" with regard to surface water drainage

Strategic flood risk assessment

The City of London Strategic Flood Risk Assessment 2017 (1.3MB) (SFRA 2017) provides the most up-to-date information regarding the risks the City faces from river and coastal, surface water, sewer and ground water flooding. This demonstrates that there are relatively small areas of the City which are at risk of flooding.
