When an Approved Document refers to a named standard, the relevant version of the standard is the one listed at the end of the publication. However, if this version of the standard has been revised or updated by the issuing standards body, the new version may be used as a source of guidance provided it continues to address the relevant requirements of the Regulations.

Volume 2 of Approved Document B currently refers to the guidance in several of the BS 5588 series of standards as a means of showing compliance with the requirements of Part B (Fire safety) of Schedule 1 to the Building Regulations. Until such time as the Approved Document is amended, these references remain part of the guidance approved under section 6 of the 1984 Building Act. As such, compliance with the guidance referred to would confer a legal presumption of conformity with the relevant requirements of Part B.
Following any other guidance would not confer that legal presumption.

Where designers elect to follow the relevant guidance in BS 9999 they will need to satisfy themselves and the building control body that this guidance adequately addresses the requirements of Part B. It is strongly recommended in such cases that designers discuss their proposals with the building control body before starting work.
