Approved Document Q Overview

What is an approved document?


Approved documents set out what, in ordinary circumstances, may be accepted as reasonable provision for compliance with the relevant requirements of the Building Regulations to which they refer. If you follow the guidance in an approved document, there will be a presumption of compliance with the requirements covered by the guidance. However, compliance is not guaranteed; for example, ‘normal’ guidance may not apply if the particular case is unusual in some way.
