A fire and security engineer installs, commissions and maintains the kit that other security workers monitor — fire alarms, intruder alarms, access control, CCTV, fire suppression systems. The job is mobile (most engineers cover a regional patch from a company van) and split between install work on new builds and reactive call-outs to existing systems.
The qualifications matrix is dense. ECS card or CSCS for site access. FIA modules — Foundation through Module 4 — for fire alarms. BAFE SP203 if you want to commission and certify. Skills for Security accreditation for intruder and access control. IPAF or PASMA for working at height. Most engineers stack three or four of these and pick up the rest over a couple of years on the job.
Rates depend heavily on how much certification you've banked. Trainee or apprentice: £24-£28k. Engineer with FIA F1-F4: £35-£42k. Service or commissioning engineer with BAFE: £42-£55k. Senior installer or project lead: £55k+. London and the Home Counties pay £3-£5k above the rest of the country. The work is steady — fire systems need periodic servicing by law, so the maintenance side smooths out the lumpy install pipeline. Most contracts include a van, a fuel card, and a phone.

Frequently asked questions
What qualifications does a fire and security engineer need?
Common entry credentials are ECS or CSCS card for site access, FIA modules F1-F4 for fire alarms, BAFE SP203 for commissioning and certification, Skills for Security accreditation for intruder systems and access control, and IPAF or PASMA for working at height. Most engineers stack three or four of these and pick up the rest over the first couple of years on the job.
What does a fire and security engineer earn?
Trainee or apprentice: £24-£28k. Engineer with FIA F1-F4 certification: £35-£42k. Service or commissioning engineer with BAFE SP203: £42-£55k. Senior installer or project lead: £55k+. London and the Home Counties pay £3-£5k above the rest of the country.
Is fire and security engineering a steady career?
Yes. Fire systems must be serviced by law on a fixed schedule, which keeps maintenance work predictable through quieter install pipelines. Most engineers split their time roughly 60/40 between new installs and reactive or scheduled service.
