What is a competent person for fire alarm work?

Direct answer

A competent person for fire alarm work is someone who has the training, knowledge, experience, and resources needed to carry out a specific task correctly and safely — for example, designing, installing, commissioning, or maintaining a fire detection and alarm system in accordance with BS 5839-1. Competence is always judged against the task at hand, not against a single qualification. Third-party certification schemes (such as BAFE SP203-1) are a recognised way for the responsible person to gain assurance that a contractor is competent. Check what is required for your premises against the current edition of BS 5839-1 and any requirements set by the relevant enforcing authority. For most premises this is the fire and rescue authority for the area. Your property insurer may set its own requirements as well; these are contractual, not statutory.

What "competent" means

BS 5839-1 defines a competent person as someone suitably trained and qualified by knowledge and practical experience, and provided with the necessary instructions, so that the required task can be carried out correctly. The standard also notes that maintaining competence is likely to require continuing professional development (CPD) — a qualification obtained years ago is not, on its own, evidence of current competence.
It is assessed against the task: someone competent to carry out the weekly test is not necessarily competent to design or commission a system.
BS 5839-1 refers throughout to work being carried out by a competent person; it does not reduce competence to a single certificate.
BS 5839-1 applies competence in two ways: to the person doing the work (for example commissioning), and to the person who signs the certificate for that work. The signatory has to be competent to judge whether the standard's recommendations for that stage have been satisfied — the standard warns that liability can arise for an organisation that issues a certificate without due care. See What certificates should a fire alarm system have?.

Who needs to be competent

Design, installation, commissioning, maintenance and modification of the system should be carried out by, or under the responsibility of, a competent person — see How often should a fire alarm system be serviced? and Fire alarm commissioning and handover: what to expect.
The responsible person for the premises does not have to do this technical work themselves, but is accountable for ensuring competent people are used — see What are the duties of the Responsible Person for a fire alarm system? (Standards & Compliance).

How a responsible person gains assurance of competence

Use organisations or individuals certified under a recognised third-party scheme. For non-domestic fire detection and alarm systems the relevant scheme is BAFE SP203-1, which covers design, installation, commissioning and maintenance — see What is BAFE SP203-1 and why does it matter?. BAFE owns and maintains the scheme; the assessment itself is carried out by a UKAS-accredited certification body licensed by BAFE. Certification by a UKAS-accredited body gives the strongest independent assurance, because the certification body's own competence is itself independently accredited. Ask a contractor which scheme they hold and which body certifies them, and check the registration is current and covers the work you need.
Ask for evidence of relevant training, qualifications, experience, and references for similar work.
Keep records (certificates, service reports, the log book) that show competent people carried out the work — see What should be recorded in the fire alarm log book?.

What this is not

Competent-person requirements apply regardless of the size of the premises or the complexity of the system — the standard of competence required scales with the task, but the obligation to use a competent person does not disappear for simpler installations.
Competence also has a separate statutory meaning. In England and Wales, article 18 of the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to appoint one or more competent persons to assist in undertaking the preventive and protective measures, and defines a person as competent for that purpose where they have sufficient training and experience or knowledge and other qualities to properly assist. Equivalent legislation applies in Scotland and Northern Ireland. This statutory duty is separate from — and additional to — the competence that BS 5839-1 recommends for design, installation, commissioning, maintenance and modification. Your property insurer may also set its own requirements; check the policy.
A single course or badge does not, by itself, make someone competent for every task.
The routine weekly test can be carried out by a suitable person nominated by the responsible person and does not require the same competence as servicing or commissioning — see How to carry out the weekly fire alarm test.

Safety note

This article is general guidance for Hochiki Europe products. Design, installation, commissioning, maintenance and modification of fire detection and alarm systems should be carried out by, or under the responsibility of, a competent person in accordance with the applicable standards (for example BS 5839-1 in the UK). Statutory requirements imposed by the relevant enforcing authority also apply. Always refer to the current product manual and data sheet for the exact model before carrying out any work.
