Flood Risk Assessment for Housing
Chartered engineers at RIDA Reports deliver flood risk assessment for housing in the UK using 21 years of experience, the latest Environment Agency data and flood modelling.
Our reports clearly show if your site lies in a high-risk flood zone, whether a formal FRA is required and solutions on how to mitigate the flood risk.
We stay compliant with the UK planning policy, and our chartered engineers use detailed data and advanced methods to produce clear and compliant flood risk reports for planning permission.



We Use Detailed UK Flood Data for Site-Specific Assessments
We review your site using the official Environment Agency’s flood map for planning to check whether your site falls in flood zone 2 or 3 and the latest planning policy maps to determine the flood zone 3b.
We evaluate all flood sources and climate projections for an approval-ready flood risk assessment report.
Our reports are based on site drawings, local Strategic Flood Risk Assessment data, EA river and surface water models (such as product 6) for UK-compliant flood risk assessment for housing.
Our Clients






We Evaluate All Flood Sources of Flood
RIDA Reports evaluate all flood sources on and around your housing site. The sources include river, coastal, surface water, groundwater, reservoirs, and sewer water.
We also quantify each flood source by combining national flood maps and local incidents. Our reports include information on the flood exposure of your housing project.
Our reports answer your questions like “How much flood risk does my site face?” or “Can we get planning with the current land use?”


We Provide Sequential and Exception Test Planning
As part of flood risk assessment for housing, we perform a Sequential Test and, where required, the Exception Test.
Our goal is to identify the safest reasonably available site for your development and to demonstrate that the proposed site has been appropriately assessed and is safe to develop a house in a flood-risk area.
Flood Risk Reports Include Climate Assessments
Our flood risk assessment reports include future climate change; we agree on the correct EA climate change allowances for your site and test higher flood levels accordingly.
Our robust assessment process ensures flood risk report looks as far as possible into future impacts.
Practical Flood Resilience Solutions
Our reports not only assess your site’s flood risk but also include solutions tailored to your portfolio. Our solutions are cost-effective, preventive and defensive.
Our solutions include but are not limited to emergency evacuation plans, strategic consultancy, coordination with architects on property levels, ground levels, landscape design and improved drainage, like SuDS.
Our FRAs are Clear and Compliant
Our flood risk assessment reports are presented in plain English and organised into clear sections for easy understanding. Each FRA is written to meet the UK planning NPPF and NPPG rules to get planning approval.
We follow EA’s standard FRA template and NPPF guidance, so local councils accept and approve our findings right away!
Our reports are structured to enable planning officers and buyers to quickly understand and assess site risk, policy compliance, and resilient solutions.
RIDA Reports obtains credible data from sources such as the Environment Agency and pairs it with our engineers’ expertise and experiences to produce a planning permission-ready flood risk assessment report.
