What Does a Flood Risk Assessor Do?
A flood risk consultant assesses how flooding may affect a development site and whether a proposal can proceed safely under UK planning policy.
Where required, we work alongside drainage engineers, hydraulic modellers and planning consultants to ensure flood risk and drainage strategy are aligned.
We provide structured, evidence-based assessments proportionate to development scale.
Our role as flood risk assessment consultants includes:
- Interpreting Environment Agency Flood Zones
- Assessing river, tidal, surface water and groundwater risk
- Identifying floodplain constraints
- Reviewing climate change allowances
- Advising on safe access and egress
- Supporting the Sequential Test and Exception Test
- Preparing planning-ready Flood Risk Assessment reports
When Do You Need a Flood Risk Specialist?
A Flood Risk Assessment is required in specific situations where flood risk may affect planning decisions, development proposals, or property use.
A planning authority requests a Flood Risk Assessment
A site lies within Flood Zone 2 or Flood Zone 3
Surface water flood risk is identified on mapping
Early engagement reduces planning risk, avoids delays and improves submission clarity.
In many cases, consultants are required where planning policy triggers the need for an assessment. If you are unsure whether your project requires one, see when a flood risk assessment is required, which outlines the key thresholds and scenarios.
