Fire Extinguisher Regulations UK — Compliance Guide for Businesses

Are your fire extinguishers legally compliant? UK law is strict on types, numbers and annual servicing. Find out exactly what's required — and what inspectors check for.

Are Fire Extinguishers a Legal Requirement in the UK?

Yes. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must ensure that appropriate firefighting equipment is provided, maintained and accessible. For virtually all commercial premises this means fire extinguishers. The number, type and placement required depends on the size, use and fire risk of the premises.

Which Types of Extinguisher Do I Need?

The correct type of extinguisher depends on the fire risks present. Most commercial premises require at least a water or foam extinguisher for Class A fires (wood, paper, textiles) and a CO2 extinguisher for electrical equipment. Kitchens require wet chemical extinguishers for Class F fires (cooking oils). BS 5306-8 and a fire risk assessment will determine the correct provision.

How Many Extinguishers Do I Need?

BS 5306-8 requires a minimum of two extinguishers per floor, with a travel distance of no more than 30 metres to the nearest appropriate extinguisher. In practice, larger premises, multi-storey buildings, and high-risk areas will require more. FireJet can survey your premises and recommend the correct provision.

How Often Must Extinguishers Be Serviced?

BS 5306-3 requires annual inspection and service of all fire extinguishers by a competent engineer. Extended service (discharge and refill) is required every 5 years for most types, or every 10 years for CO2 extinguishers. A service label and certificate must be issued after every service visit.

Consequences of Non-Compliance

Failing to provide or maintain fire extinguishers is a breach of the RRO and can result in enforcement notices, fines, and in serious cases, prosecution. Fire inspectors carry out regular audits of commercial premises and will require immediate remedial action for any deficiencies found.
