Why Is a Flood Risk Report Required in Greater London?

A flood risk report in Greater London is often a legal requirement for developments in or near designated flood zones, or where local drainage systems are limited.

These reports allow planning authorities in Greater London to determine how a proposed development will address potential flood risks without negatively impacting surrounding areas, ensuring compliance with safety and environmental regulations.

Which Types of Developments in Greater London Require a Flood Risk Report?

We prepare flood risk reports in Greater London for a wide range of developments where planning regulations require them, including:

• Developments located within Flood Zones 2 or 3 – Areas with a higher risk of flooding from rivers or the sea.
• Sites larger than one hectare – Regardless of their flood zone classification.
• Properties close to rivers, reservoirs, or the coast – Where proximity to water increases the likelihood of flooding.
• Locations with a history of surface water flooding – Even if they are outside official flood zones.
• Projects where the local planning authority mandates it – As part of the planning approval process.

How Much Does a Flood Risk Report Cost in Greater London?

The cost of a flood risk report in Greater London ranges from £500 to over £1,500, depending on factors such as site size, flood zone classification, and the complexity of the analysis.
