THE DIFFERENCE BETWEEN

Approved Document B

Fire Safety Legislation

The Building Regulations are a Statutory Instrument made under powers provided in the Building Act 1984. The current edition, ‘The Building Regulations 2000’ (as amended), applies in England and Wales to the majority of building projects. They are in place to ensure the health and safety of people in and around all types of buildings and set out the minimum performance requirements for both design and construction.

The Building Regulations are divided into fourteen sections, with fire safety covered by Part B. The regulations in Part B are accompanied by Approved Document B - Volume 1 (Dwellinghouses) and Volume 2 (Buildings Other Than Dwellinghouses). Whilst not mandatory, Approved Document B provides design and specification guidance which, if followed, will be deemed to satisfy the Building Regulations. If other methods are used to meet the requirements of the Building Regulations, the applicant or designer must assume responsibility for proving compliance.

Much of the guidance given in Approved Document B relates to the fire performance of the products and materials to be used in the construction, primarily because they can have a significant bearing on the spread of fire and its growth. Any building work, which is subject to the requirements imposed by Schedule 1 of the Building Regulations, should, in accordance with regulation 7, be carried out with proper materials and in a workmanlike manner. Materials that comply with Regulation 7 will:

  • Bear a CE marking
  • Comply with a technical specification (such as a British Standard or an alternative national specification)
  • Be covered by a national or European certificate issued by a European technical approval issuing body
