Download the guide AD O Noise Guide

The guide sets out a method to demonstrate compliance to the Building Control Body of the noise constraints in Approved Document O. It provides clarity for practitioners and regulators so that assessments can be carried out consistently, and the outcome is repeatable and reliable. Whilst the requirements of Approved Document O are succinct, there is some ambiguity regarding important details.  Some of these have been addressed in the guide.

This document provides guidance for practitioners when implementing the standards within the Building Regulations (2010) Approved Document O (England) relating to noise. It is designed to assist in understanding the guidance in the regulation and provide interpretation and clarification on the content of the published regulation.

The guide replaces the the consultation copy published in 2022 which is no longer available.
