What are the requirements in BS 7671:2018 for fire stopping?

BS 7671:2018 Regulation 527.2 sets out the requirements for the sealing of wiring system penetrations, Regulation 527.2.1 states that:

“Where a wiring system passes through elements of building construction such as floors, walls, roofs, ceilings, partitions or cavity barriers, the openings remaining after passage of the wiring system shall be sealed according to the degree of fire-resistance (if any) prescribed for the respective element of building construction before penetration.”

Whilst BS 7671:2018 states that fire stopping is a requirement, it does not detail how it should be carried out or who should do it. For this, it is important to seek further guidance from specialist contractors and manufacturers such as ClearView.

Other Requirements

The Building Regulations for use in England only state basic requirements and do not provide technical information on how to specify the correct fire stopping products.

Approved Document B 2019 Volume 1 ‘Dwellings’, Section 9 sets out the requirements for fire stopping and states that openings through a fire-resisting element for pipes, ducts, conduits or cable should be as few and small as possible and fire stopped.

Whose Responsibility is it to Carry Out the Fire Stopping Works?

BS 7671:2018 imposes requirements on the electrical installer to ensure penetrations for wiring systems are sealed to prevent the spread of fire. However, the electrical designer may decide to employ a specialist contractor to carry out the works.

On smaller projects, the electrical installer will likely be the only person involved in the works, so it will be their responsibility to ensure that the fire stopping works are completed adequately.

On larger projects, it can sometimes be assumed that the fire stopping will be carried out by the main contractor, but this is not always the case. It is important to establish where the responsibility lies at an early stage, such as when tendering for a project. The architect will likely be responsible for specifying fire stopping works, but this should be clarified with the principal contractor during the tender process.

Responsibility for Compliance

People who are responsible for building work (e.g. agent, designer, builder or installer) must ensure that the work complies with all applicable requirements of the Building Regulations. The building owner may also be responsible for ensuring that work complies with the Building Regulations. If building work does not comply with the Building Regulations, the building owner may be served with an enforcement notice.
