Is this you?
You work nights. Or you’d rather work nights. Monday to Thursday, done by Thursday morning, three days off every week. If that shift pattern genuinely fits your life – childcare, a partner’s schedule, or simply a preference for working without the daytime noise around you – this role was built around exactly that.
You’re a senior AC engineer with at least five years in commercial environments. You’ve moved past the learning phase. You know your way around VRVs, VRFs, splits and refrigeration, and you don’t need anyone checking your work.
If the idea of one fixed site, one long-term contract, and full ownership of your own work appeals – keep reading.
What you’ll be doing as a Senior AC Engineer
This is the flagship contract for a specialist HVAC and refrigeration business – a major Heathrow terminal, held for years, recently renewed with four more years to run. Your job is to own it.
The core of the work is PPM across the terminal’s AC and HVAC systems – VRVs, VRFs, splits, humidors and ice machines. But the business doesn’t want an engineer who ticks boxes and moves on. They want someone who looks at a unit and thinks ahead – what’s likely to fail, when, and how to prevent it before the summer peak puts pressure on everything.
Reactive work is handled during the same night windows. Night-only access is fixed – that’s how Heathrow works – so how you plan your time on site matters. This isn’t 50 callouts a day across multiple sites. It’s one location, one client, managed properly.
Reporting goes through a CRM system. The airport client expects thorough documentation – what was done, what was observed, what’s coming next. If you already write decent job notes, this fits naturally.
Where you’ll be doing it
A specialist HVAC and refrigeration contractor, with a long-standing presence at Heathrow and authorised signatory status on site. The team is small and direct – director, service manager, coordinator. Support from the office is practical and responsive. You’ll be trusted to run your own show on site, but you won’t be left to figure things out alone.
What you’ll need
F-Gas certification and a full UK driving licence. Security clearance eligibility for airside access – if you’ve worked in regulated environments before, this is familiar territory. At least five years of commercial AC or HVAC service experience is the baseline.
What you’ll get
£50,000-£55,000 (top of range on successful completion of probation)
Company van, phone and tools
25 days holiday
Monday to Thursday nights, maximum 8 hours – and often less. Your weekend starts Friday morning.
