Fire stopping is the installation of tested, third-party certified systems that reinstate the fire and smoke resistance of compartment walls and floors wherever they are breached by services — pipes, cable trays, ductwork, busbars and combustibles. Every penetration is treated as a discrete detail, installed strictly to the manufacturer's tested system scope, and documented with photographic evidence on OneTrace so the as-built record matches the design intent.
Main contractors and M&E packages on new build, fit-out and refurbishment projects, plus FM teams and social housing providers running planned compliance works on existing stock.
Required under Approved Document B of the Building Regulations and the Regulatory Reform (Fire Safety) Order 2005. Forms a core part of the Building Safety Act 2022 'golden thread' of information for higher-risk buildings.
