Flood Risk Assessments

We deliver flood risk assessments that unlock development potential for projects of all sizes - from single-plot extensions to major infrastructure. Our team evaluates risk from rivers, coastal, surface water, groundwater, and sewers against national and local planning policy.

5-10 day turnaround Policy-aligned
Flood risk analysis
What we do

Evidence that satisfies planners.

We assess flood risk for sites in Flood Zones 2/3, sites over 1 ha in Flood Zone 1, and developments near main rivers. We interpret NPPF Sequential and Exception Tests and translate policy into clear actions.

We keep delivery fast by assigning a dedicated technical lead and a supporting analyst from day one.

Our Approach

Four focused steps that deliver approvals.

  1. Baseline risk review

    We compile EA, SEPA, and local authority datasets and confirm planning triggers.

  2. Site-specific analysis

    We test flood pathways, constraints, and safe access/egress requirements.

  3. Mitigation design

    We propose finished floor levels, storage, and resilience measures that work.

  4. Planning-ready report

    We deliver a concise FRA with clear recommendations and evidence tables.
