Fire & Security Engineer Jobs London – Alarm, CCTV & Access Control

London is the UK's most active market for commercial fire and security engineers. The capital's concentration of Tier 1 office buildings, retail destinations, hotels, and NHS trusts generates sustained demand for BS 5839-certified fire alarm engineers, CCTV commissioning technicians, and access control specialists. Most corporate clients in the City of London and Canary Wharf mandate NSI Gold or SSAIB registration from all maintenance contractors, which means London employers typically pay a premium for engineers who hold FIA or BAFE SP203 qualifications.

Salaries for fire and security engineers in London carry a significant premium over the national average. A maintenance engineer with 3–5 years' experience typically earns £38,000–£50,000 in the capital, while commissioning engineers with BS 5839-1 design experience can command £52,000–£65,000. Subcontract day rates for fire alarm engineers in London range from £250 to £350 per day for experienced engineers working on Tier 1 commercial contracts. Most full-time roles include a zone 1–3 travel allowance or company vehicle.

Key London employers include Chubb Fire & Security, ADT Commercial, Tyco Building Technologies, and Gunnebo, alongside FM prime contractors such as Mitie, Securitas, Sodexo, and Equans. Contractors working on behalf of investment banks, law firms, and media organisations in the West End and City tend to offer the most competitive packages. The West End retail and hospitality sector also provides a large volume of maintenance contracts for smaller specialist firms.
