HVAC Engineer Jobs London – Commercial Heating & Cooling Vacancies

London is the UK's largest market for commercial HVAC engineers. The capital's concentration of Class A offices, data centres, hospitals, and retail destinations creates sustained demand for F-Gas Cat 1 engineers, BMS specialists, and multi-skilled FM technicians. Most London roles are site-based single-site contracts within the City, Canary Wharf, or the South Bank commercial zones, though mobile roles covering Greater London are common with larger FM contractors.

Salaries for commercial HVAC engineers in London carry a 15–25% premium over the national average. An engineer with 3–5 years' experience and F-Gas Cat 1 typically earns £42,000–£52,000 in London, rising to £55,000–£70,000+ for BMS engineers or those managing plant rooms in Tier 3/4 data centres. Most London roles include travel card or zone 1–3 travel allowance in lieu of a company vehicle.

Key London employers include CBRE GWS, Mitie, ISS Facility Services, Integral UK, Cushman & Wakefield, and Apleona. Contractors working on behalf of major banks, law firms, and media organisations in the City tend to offer the most competitive packages. Data centre FM (Digital Realty, Equinix, CyrusOne) is a growing segment with above-average pay for engineers with critical systems experience.
