Flood Risk Assessments (FRAs)

We provide Flood Risk Assessments (FRAs) to support planning applications for residential and commercial development.

Whether your site is located within Flood Zone 1, 2, or 3, we produce clear, policy-compliant reports that assess flood risk and set out appropriate mitigation measures where required.

Two Levels of Assessment

We provide Flood Risk Assessments proportionate to the requirements of the site and the planning application.

Proportionate FRA (EA Standing Advice)

For lower-risk sites, we can produce a concise assessment aligned with Environment Agency Standing Advice.

This is typically suitable for:

  • Flood Zone 1 developments
  • Minor development or householder applications
  • Sites with low or manageable flood risk

These reports are streamlined and focused, helping to support planning without unnecessary cost or complexity.

Full Flood Risk Assessment

For higher-risk or more complex sites, we provide a detailed Flood Risk Assessment.

This is typically required for:

  • Development within Flood Zones 2 and 3
  • Larger or more complex schemes
  • Sites with identified flood constraints
  • Applications requiring detailed consultation with the Environment Agency

These reports include a more detailed assessment of flood mechanisms, mitigation, and site-specific considerations.

When is a Flood Risk Assessment Required?

An FRA is typically required for:

  • Development within Flood Zones 2 or 3
  • Sites greater than 1 hectare in Flood Zone 1
  • Developments at risk of surface water flooding
  • Planning applications where requested by the Local Planning Authority

We can advise early on whether an FRA is required and the appropriate level of assessment.

What Our FRA Includes

Our Flood Risk Assessments are prepared in line with national and local planning policy and typically include:

  • Review of Environment Agency flood mapping
  • Assessment of fluvial, surface water, and other flood sources
  • Consideration of climate change allowances
  • Site-specific risk analysis
  • Mitigation measures where required
  • High-level drainage strategy where appropriate

All reports are tailored to the site and level of risk.

Supporting Planning Approval

We understand what Local Planning Authorities and consultees expect.

Our aim is to:

  • Provide a report that supports planning approval
  • Address flood risk clearly and proportionately
  • Avoid unnecessary complexity or over-reporting

Where required, we can coordinate with drainage design and wider civil engineering input.
