UK listing requirements
Fire sprinkler installations in the UK under Approved Document B of the Building Regulations 2010 require compliance with BS EN 12845 for automatic sprinkler system design, installation and maintenance. Insurance-led specifications additionally reference LPC Rules for Automatic Sprinkler Installations incorporating BS EN 12845, published by the Fire Protection Association.
Component listing under BS EN 12845 requires sprinklers to be listed by a recognised third-party body. LPCB (Loss Prevention Certification Board, BRE Global) and FM Approvals are the UK-recognised listing bodies. Where a UK specification requires LPCB approval, confirm acceptance of UL-listed sprinklers with the insurer before ordering.
Our sprinklers carry UL Listed certification under UL 199 for commercial occupancy. For LPCB-specific projects (insurance-led or where the specification explicitly requires LPCB), confirm acceptance with the insurance surveyor before ordering. FM Approval on our sprinklers is accepted by FM Global and by UK insurance surveyors and specialist fire property underwriters operating on the FM component listing standard.
Residential life safety sprinkler systems under BS 9251 require sprinklers listed for residential service under UL 199 or an equivalent residential certification. Our sprinklers are commercial-listed under UL 199 and do not currently carry a residential listing; for BS 9251 projects, ValveAtlas coordinates residential sprinkler supply through partner distribution.
London project types and sprinkler selection
Commercial office high-rise. City of London, Canary Wharf, Kings Cross, Paddington and White City commercial developments specify automatic sprinkler protection to BS EN 12845 OH1 or OH2 hazard. UV321 pendent QR at 68°C or 93°C ordinary temperature is the default selection. UV821 concealed pendent QR covers finished ceiling areas. Standpipe risers under BS 9990 for firefighting water supply use UVW-1511-300 wet alarm valve with UL/FM certificates.
Residential high-rise post-Grenfell. London residential high-rise over 18 metres under the Building Safety Act 2022 requires enhanced fire safety measures. The sprinkler scope within dwelling units specifies residential sprinklers under BS 9251, coordinated through ValveAtlas. Non-dwelling common areas specify commercial sprinklers under BS EN 12845 covered by UV320/UV321 pendent or UV340/UV341 sidewall. UV820/UV821 concealed pendent for architectural ceiling continuity.
Data centres. London and Slough data centres specify FM-approved pre-action sprinkler systems. UV310 upright SR feeds off UVPR-5311-300 pre-action valve with cross-zoned detection per FM Global Data Sheet 5-32. Mechanical and telecommunications rooms (MMR, MOP) use wet pipe with UVW-1511-300 alarm valve.
Warehouse distribution. Distribution operators in Greater London (Dartford, Enfield, Thurrock) specify FM-insured logistics with ESFR protection. UV310 and UV320 serve the ordinary hazard portions of the property.
Healthcare, pharmaceutical and life sciences. NHS trusts, pharmaceutical companies and life sciences manufacturers specify LPCB-listed components for HTM 05-02 compliance and ABPI guidance. Our sprinklers carry UL/FM listings; where LPCB-specific certificates are required, coordinate with the insurance surveyor before ordering.
