How much do heat pump installers earn in the UK?

Air source heat pump installation is one of the fastest-growing trades in the UK - and one of the few where the shortage of qualified people is actively pushing pay up. Here's an honest picture of earnings and what moves the number.

Note on figures. Pay varies widely by region, employer, experience and whether you're employed or self-employed. Treat any range as a rough guide and check current job listings for live rates - we deliberately don't quote a single misleading number.

What drives the pay

Three things move a heat-pump installer's earnings more than anything else:

  • Qualification. A recognised Level 3 ASHP qualification is the baseline employers hire on.
  • MCS registration. Being able to certify installations unlocks grant-backed work (the £7,500 Boiler Upgrade Scheme), which is where a lot of the paid work is.
  • Employed vs self-employed. Day rates for established self-employed installers can sit well above an equivalent salary, but carry the usual risk and admin.

Why demand - and pay - are rising

The UK's net-zero push means hundreds of thousands more heat pumps need installing this decade, and there simply aren't enough trained, MCS-certified installers to do it. When supply is short, qualified people can command more. That scarcity is the whole reason this trade is worth moving into - and why some employers even sponsor overseas installers on Skilled Worker visas.

How to put yourself at the top of the range

The earning lever you fully control is getting qualified. Experienced plumbers use the RPL route to certify at Level 3 for Air Source Heat Pumps by passing the knowledge exam - no full college course. Clear that, complete MCS registration, and you go from "unqualified applicant" to "ready, certifiable installer" - the difference that decides your rate.

FAQ

Do qualified heat pump installers earn more than gas engineers?+

Heat-pump work is a growth area with a shortage of qualified, MCS-certified installers, so demand is pushing rates up. Many experienced installers move across from gas precisely because the heat-pump side is expanding while demand for new gas boilers is set to fall.

Does being MCS-certified increase earnings?+

MCS registration lets you certify installations and access grant-backed work like the Boiler Upgrade Scheme, which is where much of the paid heat-pump work sits. Qualified, certifiable installers are simply more valuable to employers and customers.

How do I become a qualified heat pump installer?+

Experienced plumbers usually take the RPL (Recognition of Prior Learning) route: certify at Level 3 for Air Source Heat Pumps by passing the knowledge exam rather than doing a full college course, then complete MCS registration. passrpl is exam-prep for that knowledge test.
