Who can service a fire alarm?
What level of competence is required to service a fire alarm system, what BAFE certification means, what to look for when appointing a contractor, and why competence matters.
BS 5839-1 requires fire alarm servicing to be carried out by a competent person. The standard does not define a specific qualification or licence — it defines competence by the outcome: the person must have sufficient training, experience, and knowledge to carry out all required tests correctly and identify any deficiencies. In practice, third-party certification is the clearest and most defensible evidence of that competence.
The Competence Requirement
The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire precautions in efficient working order. BS 5839-1 requires that maintenance is carried out by a competent person. Neither document defines a specific qualification — but both place the burden of demonstrating competence on the person carrying out the work.
Competence in this context means having the appropriate training, technical knowledge, and hands-on experience to carry out all the tests and inspections required by BS 5839-1, to correctly interpret the results, to identify deficiencies, and to produce an accurate service report. It also means having the right equipment — a calibrated sound level meter, detector test equipment, and battery test facilities.
Third-party certification
BAFE SP203-1 — the Key Certification Scheme
The principal third-party certification scheme for fire alarm maintenance in the UK is BAFE SP203-1 — the Life Safety Fire Detection scheme operated by the British Approvals for Fire Equipment. A company holding BAFE SP203-1 certification has been independently assessed against the requirements of BS 5839-1 for design, installation, commissioning, and maintenance of fire alarm systems, and is subject to ongoing surveillance audits.
Using a BAFE SP203-1 certified contractor provides the building owner with:
- Evidence that the contractor has been independently audited for competence
- Assurance that their engineers are appropriately trained and assessed
- A route for complaint and recourse if the work is deficient
- Compliance with many insurer requirements that specify certified contractors
- A defensible position if the adequacy of maintenance is ever questioned by an enforcing authority
| Certification scheme | Operator | What it covers |
|---|---|---|
| BAFE SP203-1 | BAFE (British Approvals for Fire Equipment) | Design, installation, commissioning, and maintenance of life safety fire detection and alarm systems to BS 5839-1 |
| NSI Gold / Silver | National Security Inspectorate | Fire alarm and security system installation and maintenance — NSI Gold includes third-party product certification |
| SSAIB | Security Systems and Alarms Inspection Board | Fire and security alarm system installation and maintenance |
Is certification legally required?
Legal Status of Certification
Third-party certification is not a legal requirement — there is no law that says fire alarm maintenance must be carried out by a BAFE-certified contractor. However, using an uncertified contractor creates a higher burden of proof on the building owner to demonstrate that the maintenance met the competence requirements of BS 5839-1. An uncertified contractor’s competence must be demonstrated by other means — qualifications, experience records, and references — which is more difficult and less certain.
Additionally, many commercial insurers now require BAFE certification as a condition of cover. A fire alarm system maintained by an uncertified contractor may result in a claim being disputed or rejected if a fire occurs.
What to look for
Appointing a Maintenance Contractor
When appointing a fire alarm maintenance contractor, check the following before signing any contract:
- BAFE SP203-1 registration — verifiable on the BAFE website at bafe.org.uk
- Experience with your system type — not all contractors are equally familiar with all panel manufacturers and addressable systems
- Response times for emergency call-outs — what is their guaranteed response time for a fault call?
- Service report format — ask to see a sample service report before appointing
- Insurance — public liability insurance of at least £5 million is standard
- References from similar premises — a contractor who mainly works on small domestic systems may not have the experience needed for a complex addressable installation
Common questions
Frequently Asked Questions
In principle yes — provided the in-house team members are genuinely competent to carry out all the required tests and produce compliant service documentation. In practice, most in-house facilities teams do not have the specialist training, test equipment, or experience to meet the full requirements of BS 5839-1 for a Grade A system. An in-house team may carry out the weekly tests and basic visual checks, but the six-monthly and annual service visits should be carried out by a specialist contractor. The maintenance contract should be structured accordingly.
Not without additional specialist training. General electrical competence is not sufficient for fire alarm servicing. A fire alarm system involves specific panel programming, addressable device protocols, detector sensitivity testing, battery management, and ARC connection testing — none of which are covered by standard electrical qualifications. An electrician who carries out fire alarm maintenance without specific fire alarm training and experience is not a competent person for this purpose under BS 5839-1.
