At Flood Risk Reports, we provide detailed, planning-compliant flood risk reports for properties and development sites across the UK.

Whether you are applying for planning permission, purchasing a site, or protecting an existing property, our reports assess flood risk levels and recommend effective mitigation solutions.

We combine extensive local insight with national standards to ensure your report meets the requirements of planning authorities, the Environment Agency, and potential investors.

Why Is a Flood Risk Report Required?

A flood risk report 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 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 Require a Flood Risk Report?

We prepare flood risk reports 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?

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

Costs are influenced by requirements for hydraulic modelling, the availability of historic flood records, detailed drainage capacity reviews, and any additional site inspections or mitigation recommendations.

How Is a Flood Risk Report Carried Out?

Our flood risk reporting involves combining Environment Agency data, local authority records, and site-specific inspections to produce an accurate assessment.

We evaluate land levels, existing drainage systems, and water flow patterns to understand the potential flood impact during extreme weather. When required, advanced hydraulic modelling is used to simulate realistic flood events and pinpoint vulnerable areas.

Are Flood Risk Reports Necessary for Planning Applications?

A flood risk report is an essential document for planning applications, especially for developments in designated flood zones or areas with drainage challenges.

Submitting a compliant and thorough report can increase your chances of approval by demonstrating that the development will be managed with effective flood risk measures.

Can a Flood Risk Report Recommend Mitigation Measures?

Our flood risk reports not only assess the potential level of flooding but also include practical recommendations to reduce risk.

These may include elevating floor levels, installing flood defences, enhancing drainage capacity, or integrating sustainable drainage systems (SuDS). Implementing these measures can help meet planning conditions and protect the site in the long term.

How Long Does It Take to Complete a Flood Risk Report?

A standard residential flood risk report can generally be completed within one to two weeks.

Larger or more complex developments, particularly those requiring hydraulic modelling, may take longer. We work within agreed timeframes to ensure your planning application remains on schedule.

What Information Is Included in a Flood Risk Report for the Area?

A typical flood risk report for a site includes:

• Flood zone mapping – Showing the site’s location within Environment Agency flood risk categories.
• Historic flood records – Reviewing previous flood events and their impact on the area.
• Topographical analysis – Assessing land gradients and levels to determine potential water flow paths.
• Identification of flood sources – Including rivers, tidal waters, groundwater, and surface water run-off.
• Flood modelling – Predicting potential flood depths and flow velocities for various return periods.
• Drainage capacity assessment – Evaluating existing systems to determine how they handle rainfall and run-off.
• Mitigation strategies – Outlining practical measures to reduce residual flood risk.

Do Flood Risk Reports Meet Regulatory Standards?

All our flood risk reports are prepared in line with Environment Agency standing advice, Planning Policy Statement (PPS25) guidelines, and local authority planning requirements.

This ensures the report meets all relevant technical and compliance standards.
