Commercial Gas Engineer
CV-LibrarySurreypermanentPosted: 25 June 2026
Apply NowThis is a senior mobile heating engineer role covering the home counties and London. The difference from most is the range of work. You'll do planned service and full installs across commercial and domestic sites, heat pumps, surveys and small works, rather than being kept to one type of job. You'll need commercial gas safe and a few years behind you.
Is this you?
You hold commercial gas safe qualifications - ACS commercial, not domestic-only. That's the part that matters. You've spent years on planned service and installation across commercial and domestic sites, and you know the work cold: boilers, water heaters, renewables, general HVAC, fault-finding. If you've got air source heat pump experience on top, that's a real plus, but it's not the gate. The gas and the experience are what the role is built around.
What you'll be doing
You'll handle planned service on commercial and domestic combustion appliances, renewables and general HVAC, including air source heat pumps. You'll install heat pumps across residential and commercial sites, run small works projects from pipework up, and survey sites to spec out new and replacement systems. Fault-finding and troubleshooting come with the territory. You'll write your own RAMS and safe systems of work, and keep your records straight on the field service system. There's also room to take the lead on the heat pump side as it grows, if that's where you want to take your skills.
Where you'll be doing it
You'll be mobile, based ideally around the Surrey, Hampshire and Berkshire border or south-west London, covering the home counties and London as the work demands. It's a permanent role with an established building services business that does real work for schools, colleges and commercial clients, so an enhanced DBS check is part of the deal.
What you'll need
Commercial gas safe qualifications - this is the one that's non-negotiable
A full UK driving licence
A solid grounding in heating and plumbing across commercial and residential building services
The judgement to carry out planned maintenance to SFG20 or manufacturer spec
Heat pump experience is a bonus, not a barrier. If you've got the gas and the appetite to develop, the training's there
What you'll get
£50,000 - £58,000
Company van
23 days holiday plus bank holidays
Paid travel after the first hour
Paid on-call rota
Company pension and funded training and development
Permanent, full-time, 40 hours a week
What next?
If this sounds like the right fit, send over your CV - doesn't need to be perfect. Everyone gets a response
