Commercial Flood Risk Assessment
Planning-ready Flood Risk Assessments for commercial, industrial and mixed-use development across England and Wales — written to satisfy the LPA, LLFA and Environment Agency at first submission.
Flood Risk Assessments for Commercial Development
Most commercial and industrial development in Flood Zone 2 or 3 — and any site over one hectare in Flood Zone 1 — needs a Flood Risk Assessment to support its planning application. The FRA assesses flooding from all sources, demonstrates the development is safe over its lifetime, and sets out the mitigation and surface water drainage needed to make it acceptable.
Flood Risk Environmental prepares commercial FRAs for industrial and logistics units, retail and leisure schemes, offices, mixed-use blocks and change-of-use proposals. Every report is written to pass first time and dovetails with the drainage strategy the same scheme will need.

Commercial Schemes We Cover
Industrial & logistics
Warehousing, distribution units and industrial estates, where large impermeable roofs and yards drive surface water runoff that must be managed.
Retail & leisure
Retail units, supermarkets, leisure and hospitality, where safe public access and egress during a flood event must be demonstrated.
Offices & employment
Office buildings and employment land, with lifetime safety and operational continuity addressed.
Change of use
Converting commercial premises to residential or other higher-vulnerability uses, which triggers a fresh FRA against the flood-risk vulnerability classification.
Mixed-use schemes
Ground-floor commercial with residential above, balancing the vulnerability of each use within a single assessment.
Car parks, yards & works
External hardstanding and parking, where attenuation and exceedance routing are central to a compliant drainage strategy.
How It Works
Every commercial assessment follows the same structured route from data to decision.
Site & flood data review
We pull the latest EA flood data, historic records and any available modelling for your site, and confirm the flood zone and risk.
Assess & model
Flooding from all sources is assessed, with finished floor levels, access/egress and lifetime safety established.
Mitigation & drainage
We set out resilience, resistance and the surface water drainage strategy needed to make the scheme acceptable.
Report & submit
You receive a submission-ready FRA, written to satisfy the LPA, LLFA and Environment Agency at first submission.
