What you do
Heat pump installers survey properties, design heating systems, and install air-source or ground-source heat pumps to replace gas boilers. The work covers mounting outdoor units, running refrigerant pipework, connecting to existing radiator or underfloor heating circuits, commissioning controls, and handing over to the homeowner. You need a strong understanding of heating system design, refrigerant handling (F-Gas regulations), and electrical connections. Most installers hold MCS (Microgeneration Certification Scheme) certification, which is required for customers to access the government's Boiler Upgrade Scheme grant. Many installers transition from existing plumbing, heating, or refrigeration backgrounds. Specialisms include ground-source loop installation, commercial systems, and hybrid heat pump configurations. Progression routes lead to system design, project management, or running your own MCS-accredited installation business.
Why this career is resilient
The UK Heat and Buildings Strategy commits to phasing out new gas boiler installations by 2035, creating enormous demand for qualified heat pump installers. The government's Boiler Upgrade Scheme provides £7,500 grants per installation, directly funding the work. Industry estimates suggest the UK needs 50,000+ trained heat pump installers by 2030 — far above current capacity. MCS certification creates a regulatory barrier that protects skilled practitioners. Every installation is a physical, on-site job involving refrigerant handling, pipework, and electrical work that cannot be automated or performed remotely.
A typical day
Arrive at a domestic property for a two-day installation. Morning spent mounting the outdoor unit on anti-vibration feet, drilling through the wall for pipework, and running refrigerant lines to the indoor unit. Afternoon focused on connecting to the existing heating circuit, pressure-testing pipework, and charging the refrigerant system. Second day covers electrical connections, commissioning the controls, running performance checks, and walking the homeowner through their new system.
Routes in
Apprenticeship
Earn while you learn: work with an employer and study part-time, leading to a nationally recognised qualification. Typically funded by the government and your employer.
Full-time college course
Study full-time at a further education college, usually for 1–2 years. You will need to fund yourself or apply for a student loan (available for Level 4+ courses).
Employer-funded training
Some employers — particularly the NHS, emergency services, and larger care providers — run their own funded training programmes. You apply for a job and train as you work.
Pay and costs
Earning potential: Employed installers earn £30,000–£42,000. Experienced MCS-certified installers earn £40,000–£55,000. Self-employed installers running their own MCS business can earn £50,000–£70,000+ depending on volume.
Training costs: Apprenticeship: no upfront cost. F-Gas qualification: £800–£1,200. MCS certification (company-level): £1,500–£2,500 initial registration plus annual fees. Upskilling courses for existing heating engineers: £1,500–£3,000.
