Flood Risk Assessments for Planning Applications
Planning-ready FRAs from £295. 3–5 working day turnaround. Written to satisfy your LPA, LLFA and the Environment Agency at first submission.
Flood Risk Assessments for Planning Applications
We deliver planning-ready FRAs that satisfy Local Planning Authorities, Lead Local Flood Authorities and the Environment Agency — so your application is not delayed by flood risk objections. Every FRA is tailored to your specific site and development, written to satisfy the NPPF, Planning Practice Guidance and your LLFA's standing advice.
With over 17 years' dedicated flood risk and drainage experience across all LPA areas in England and Wales, we know what planning officers and LLFA consultees need — and we write our reports to address those requirements directly. Our FRAs regularly achieve planning approval at first submission without LLFA objection.
What Is Included in Every FRA
Every flood risk assessment we produce covers all sources of flood risk and is tailored to your site, your development type, and the specific requirements of your local planning authority.
- ✓ All flood sources assessed — fluvial, tidal, surface water, groundwater, sewer and reservoir flooding
- ✓ EA flood map and detailed model interrogation — including Product 4, 5 and 6 data where applicable
- ✓ Climate change assessment — latest EA allowances for your river basin district and vulnerability classification
- ✓ Sequential Test compliance — evidenced and documented for all FZ2/3 applications
- ✓ Exception Test support — where required, we prepare the full sustainability and safety case
- ✓ Finished floor level recommendations — specific, achievable, and designed to satisfy your LPA
- ✓ Safe access and egress assessment — all routes assessed for design flood plus climate change
- ✓ Flood warning and evacuation guidance — compliant with PPG requirements
- ✓ Outline surface water drainage strategy — where required by your LPA or LLFA
- ✓ Flood resilience and resistance measures — practical, cost-effective recommendations
When Is a Flood Risk Assessment Required?
Not sure if you need one? Read our full guide or contact us for free advice.
Flood Zone 2 or 3
Any development in FZ2 or FZ3 requires an FRA regardless of size. The LLFA will object without a robust FRA and drainage strategy. FZ2/3 service →
Sites Over 1 Hectare in FZ1
Large FZ1 sites require an FRA to demonstrate drainage adequacy and that surface water runoff will not increase downstream flood risk.
Major Developments (10+ dwellings)
Major applications require an FRA in any flood zone — including residential sites over 0.5ha and non-residential floorspace over 1,000m².
Change of Use
Converting commercial to residential in a flood risk area requires a new FRA confirming future occupiers will be safe for the lifetime of the development.
Flood Consequence Assessment (Wales)
Developments in Wales in DAM B, C1 or C2 areas require an FCA under TAN15 2024. TAN15 / FCA service →
LLFA Drainage Objection
Received a flood risk or drainage objection? We review it and prepare a technical response to resolve it fast. Objection response →
Our Flood Risk Assessment Methodology
Every FRA follows a structured, evidence-led process designed to satisfy the NPPF, PPG and your LLFA's specific requirements.
Data Gathering
We interrogate all available flood risk data: EA flood maps, Product 4/5/6 model outputs, historic flood records, SFRA data, geology, topography and drainage records.
All Sources Assessed
Fluvial, tidal, surface water, groundwater, sewer and reservoir flooding are all considered. We assess probability, consequence and residual risk for each source.
Climate Change
We apply the latest EA climate change allowances for your specific river basin district, vulnerability classification and development lifetime — correctly, not over-conservatively.
Mitigation Design
Finished floor levels, flood resilience measures, safe access and egress routes and evacuation procedures are designed to be practical, achievable and cost-effective.
Sequential & Exception Test
Where your site is in FZ2 or FZ3, we document Sequential Test compliance and prepare the full Exception Test case where required.
Planning-Ready Report
Delivered within 3–5 working days, ready to upload to the planning portal. Written to address the specific concerns of your LPA and LLFA, not a generic template.
Why Choose Flood Risk Environmental?
Flood risk specialists, not generalists. Unlike ecology or environmental consultancies that offer FRAs as one of many services, flood risk and drainage is all we do. That means deeper technical expertise, faster turnaround and reports that genuinely satisfy LPA and LLFA requirements first time.
17+ years' dedicated experience. We have delivered hundreds of FRAs across every LPA area in England and Wales, including complex FZ3b functional floodplain cases, tidal risk assessments and major residential Exception Test submissions.
Fixed-fee, transparent pricing. FRAs from £295 for FZ1 sites. We provide a fixed quote before starting — no hourly rates, no scope creep, no surprises. See full pricing →
Fast turnaround without cutting corners. We typically deliver within 3–5 working days. Urgent next-day service is available for time-sensitive applications.
Full coverage, no travel costs. We cover all LPA areas across England and Wales. No additional charges for remote locations — the fee quoted is the fee you pay.
