GN38 Relating drainage reports to BREEAM UK NC 2018

Latest version: v1.2, January 2023

Guidance Note 38 (GN38) has been produced to help assist BREEAM Assessors relate the contents of drainage reports to the ‘Surface water run-off’ and ‘Minimising watercourse pollution’ criteria in Pol 03 for BREEAM UK New Construction 2018 and BREEAM UK New Construction Version 6. The guidance note does not cover the criteria for ‘Flood resilience’.

Completing the template is optional. It is an aid for demonstrating compliance and not a requirement.

A separate guidance note exists for BREEAM UK New Construction 2014 (see GN15).
