The uncomfortable truth about FM salaries
Recruitment agencies have a conflict of interest: they earn a percentage of your first-year salary. The higher your offer, the more they make — but many still lowball candidates to close placements faster. Knowing your market rate is your single best negotiating tool.

5 things FM engineers get wrong in salary negotiations
Accepting the first offer
The first offer is rarely the best offer. Most FM employers have 5–15% headroom. Ask once, firmly and with a reason.
Not counting benefits in the total
Company van, fuel card, and call-out rates can add £5,000–£10,000+ to the real value of a package. Compare total compensation, not just base salary.
Waiting for annual reviews
The fastest salary jumps in FM come from moving roles, not waiting for a 2% uplift. A single job move can jump you 15–20%.
Not knowing your cert premium
Gas Safe or F-Gas qualified? You have real market leverage. If your employer isn't paying the cert premium, a competitor will.
Underselling specialist experience
Commercial hard FM is a niche. If you've worked on BMS, complex chillers, or multi-site contracts, that experience commands a premium — state it explicitly.
FM engineer salary questions
How much do commercial air conditioning and HVAC engineers earn in the UK?
A commercial HVAC or air conditioning engineer typically earns £32,000–£44,000 with 2–5 years’ experience, rising to £44,000–£58,000 at senior level and £58,000–£75,000+ for lead and supervisor roles. Trainees start around £24,000–£32,000. London and the South East add roughly 20–30% and 10–15% respectively.
How much does an F-Gas qualified engineer earn?
F-Gas Category 1 is worth roughly £2,500–£5,000 per year on top of base salary, because it is a legal requirement for handling refrigerant on commercial systems. Combined with the HVAC engineer base range, an F-Gas Cat 1 engineer with five years’ experience typically earns £38,000–£48,000 outside London and £44,000–£58,000 within it.
What is a commercial gas engineer’s salary in the UK?
Gas Safe (ACS) is the single biggest individual certification uplift in facilities management, worth around £4,000–£7,000 per year. Commercial gas engineers therefore sit at the upper end of the HVAC band, commonly £40,000–£55,000, with senior and lead roles exceeding £60,000.
How much do fire and security engineers earn?
Fire and security engineers earn £30,000–£42,000 with 2–5 years’ experience, £42,000–£54,000 at senior level, and £54,000–£68,000+ as lead or supervisor. Trainee and junior roles start at £22,000–£30,000. Commissioning experience on fire alarm systems commands the highest rates.
What is a drainage engineer’s salary in the UK?
Drainage engineers typically earn £28,000–£40,000, with CCTV drainage survey and no-dig repair specialists earning at the top of that range and above. Experienced engineers moving into subcontracting commonly bill day rates of £200–£350.
How much does a water hygiene engineer earn?
Water hygiene and legionella engineers earn in line with the wider FM technician market, with the L8 water hygiene qualification adding roughly £1,500–£3,000 per year. Demand across commercial estates has grown steadily, pushing experienced L8 engineers toward the upper end of their band.
Which UK region pays FM engineers the most?
London pays the most, at roughly 20–30% above the national baseline, followed by the South East at 10–15%. The Midlands is the baseline benchmark region. Scotland sits 5–8% below and Wales 6–10% below, though lower living costs offset much of that gap.
Which certifications increase an FM engineer’s salary the most?
Gas Safe (ACS) gives the largest uplift at £4,000–£7,000, followed by F-Gas Category 1 at £2,500–£5,000, 18th Edition (BS 7671) at £2,000–£4,000, NEBOSH General Certificate at £2,000–£3,500, Water Hygiene (L8) at £1,500–£3,000, and IPAF/PASMA at £1,000–£2,500.
