Job description

Overview

CHP Field Service Engineer - (M40 / M4 / M3 Corridor) £50,000 to £60,000 + overtime at 1.5x + door to door pay + van

Most field service roles come with a catch. You're either micromanaged, stuck doing the same thing every day, or treated like a number on a spreadsheet. This isn’t that. We're working with a small, family-owned CHP and gas power specialist. We design, build, install, and maintain our own gensets. Scania 12 and 13 series engines, CoMAP controls, landfill gas, natural gas, biogas, the lot. You’ll see the full engineering journey here, not just the maintenance end of it.

The team is tight. Four people doing the technical work. Trust is high. Nobody hovers. If you want to think for yourself, make decisions on site, and be relied on to get things done properly, you’ll fit in here.

Responsibilities

• Planned and reactive maintenance on CHP and landfill gas engines.
• Fault finding. Proper root cause work, not just resetting alarms and hoping for the best.
• If there’s a wiring fault, determine whether it’s electrical or an exhaust leak that caused damage.
• Strip downs, rebuilds, inspections.
• Minor electrical work in the workshop: gas alarms, pumps, fans, plug sockets, lights.
• Interrogating CoMAP control data and adjusting set points.
• Supporting genset builds and on-site installations when they arise.
• Role split is roughly 70% mechanical, 30% electrical and diagnostics.
• Some weeks involve servicing; others involve chasing recurring faults or wiring a new container build on site.

Qualifications

• Solid mechanical background. You understand how gas engines actually work. Scania experience is ideal, but the diagnostic mindset is what counts.
• Ability to interrogate a controller, read data, and determine the actual fault rather than just swapping parts.
• Comfort with basic electrical tasks and a desire to develop that area further.
• Self-starter who doesn’t wait to be told what to do.
• Problem-solving approach: you think it through and deal with it.
• Honesty: communicate problems openly, whether the news is good or bad.

What’s in it for you

• £50k to £60k depending on experience
• Overtime at 1.5x
• Door to door pay (day starts when you leave home, not when you arrive on site)
• Company van with personal use
• 21 days holiday plus Bank Holidays
• An extra 3 to 5 days at Christmas (workshop shutdown between Christmas and New Year, not deducted from holiday)
• Pension: 5% employer, 3% employee
• Phone allowance, laptop, PPE, specialist tools provided
• You bring your own hand tools, but you’ll likely have them already if you’ve been doing this job
• 18th Edition training
• Technical training with Sandfirden in the Netherlands (same programme the current team did)

Why people stay

“Variety. Autonomy. The fact that your opinion actually counts. You’re encouraged to develop across mechanical, electrical, and controls, not pigeonholed into one thing forever. It’s a small team, so what you do matters. You’re not a number here.”

The person you’re replacing grew into this role over years. Started as an apprentice, left, came back at a different level. He’s not disappearing either; he’ll still be on the WhatsApp group if you need a second opinion on something. That’s the kind of place this is.
