Fire Detection & Emergency Lighting Certificates

Yes, in most cases. Under the Regulatory Reform (Fire Safety) Order 2005 the responsible person for a non-domestic premises must ensure the fire detection system is tested and maintained, and a written record kept. Licensed HMOs, care homes, schools and most commercial buildings have explicit certification requirements. Insurance policies typically demand current annual certification.

BS 5839 is the British Standard covering the design, installation, commissioning and maintenance of fire detection and fire alarm systems. It is split into BS 5839-1 (commercial and non-domestic premises) and BS 5839-6 (domestic dwellings, including HMOs of 1–2 storeys). Compliance with BS 5839 is the benchmark required by insurers, regulators and most enforcing authorities.

BS 5839-1 covers commercial and non-domestic premises and uses Categories (M, L1–L5, P1–P2) to define system scope. BS 5839-6 covers domestic dwellings — single homes and HMOs of 1–2 storeys — and uses Grades (A, C, D1, D2, F1, F2) to define the type of detector and power source. Grade D1 interlinked mains alarms with battery backup are the most common HMO and rental dwelling specification.

Under BS 5839-1, a manual call point should be tested weekly (rotated through the building so every MCP is tested at least every 12 months), a visual check completed monthly, a service inspection every 6 months by a competent engineer, and a full system test annually with a certificate issued. iCertifi’s Inspection Interval Calculator works out every key date from the last inspection in seconds.

An emergency lighting certificate is the written record that an emergency lighting system has been designed, installed, commissioned, tested or serviced in accordance with BS 5266-1. The standard recognises four certificates: design, installation, commissioning, and periodic inspection & testing. iCertifi includes all four in BS 5266 model form, ready to email as a PDF on site.

BS 5266-1 requires a brief monthly function test of every luminaire and exit sign, and an annual full-rated-duration discharge test (1 hour or 3 hours, depending on the luminaire rating), with the system fully recharging afterwards. The annual test must be certified and the result recorded in the system log book.

Licensed HMOs require current fire detection certification as a condition of licence. For single-let private rentals, English law requires a working smoke alarm on every storey and a carbon monoxide alarm in every room with a fixed combustion appliance — a written test certificate at the start of each tenancy is best practice and is requested by most letting agents and insurers. Scotland and Wales have their own equivalent and stricter rules.

Grade D under BS 5839-6 is a system of mains-powered, interlinked smoke alarms with battery backup. Grade D1 uses sealed tamper-proof batteries (10-year life), Grade D2 uses replaceable batteries. Grade D1 LD2 is the typical specification for licensed HMOs in England and Wales.

BS 5266-1:2016 was the long-running edition; an updated BS 5266-1:2025 was published bringing alignment with BS EN 1838 illuminance levels and new guidance on adaptive emergency lighting. iCertifi’s emergency lighting certificates are kept current with the latest edition.

A service certificate records the routine 6-monthly or annual maintenance visit by a competent engineer — a function and integrity check of every device. A test certificate is issued after the annual full system test, with every detector, call point, sounder and zone individually tested and the result recorded. Both are part of the BS 5839-1 maintenance regime.
