BREEAM Flood Risk & Surface Water Run-off Assessments
Flood risk and surface water run-off assessments that satisfy BREEAM Pol 03 — including peak run-off rate and additional volume calculations for the credit criteria.
BREEAM Flood Risk & Run-off Assessments
BREEAM's Pol 03 (Flood and surface water management) rewards developments that assess flood risk and manage surface water run-off. We prepare the flood risk assessment and the surface water run-off calculations your BREEAM assessor needs to claim the available credits.
That means demonstrating the site's flood zone, a compliant flood risk assessment, and — for the run-off credits — showing that post-development peak rate and additional volume of run-off are no greater than pre-development (and betterment where credits require it), using SuDS in line with CIRIA C753. We provide the calculations and technical narrative packaged for your BREEAM submission.
What we provide for BREEAM
- Flood risk assessment (Pol 03)

When you need a BREEAM flood assessment
Pol 03 credits require both a flood risk assessment and run-off management evidence.
Targeting Pol 03 credits
To claim the flood risk and surface water run-off credits, your assessor needs a compliant FRA and run-off calculations showing no increase in rate or volume.
Peak rate credits
Demonstrating that post-development peak run-off is limited to greenfield (or agreed betterment) rates through attenuation and controlled discharge.
Volume credits
Showing the additional volume of run-off from the developed site is prevented from leaving the site, or managed to the required standard.
New commercial & residential
BREEAM is common on commercial, education, healthcare and larger residential schemes where planning or funding conditions require certification.
