HEAT PUMP ENGINEER SALARY UK

HOW MUCH DO HEAT PUMP ENGINEERS EARN?

A useful current benchmark for Heat Pump Engineer salaries is:

​

​

These figures should be treated as market guidance rather than fixed salary bands.

The National Careers Service currently reports £24,000 to £46,000, while Indeed's September 2026 data reports an average of £43,558 and a typical range of approximately £30,872 to £61,456.

That wider range reflects the considerable difference between someone entering the sector and an experienced heating engineer capable of installing, commissioning, fault-finding and servicing heat pump systems independently.

​

WHAT AFFECTS A HEAT PUMP ENGINEER'S SALARY?

EXPERIENCE, QUALIFICATIONS & TECHNICAL CAPABILITY

Heat Pump Engineer salaries can be influenced by several factors.

Heating & HVAC Experience

Engineers with established heating, HVAC or mechanical experience can bring valuable transferable skills into heat pump installation and maintenance.

Heat Pump Experience

Previous experience specifically installing, commissioning, servicing or repairing heat pumps can increase an engineer's value to employers.

Technical Capability

Engineers able to work independently across installation, commissioning and fault diagnosis may have access to a wider range of positions than those focused on one part of the process.

Air Source & Ground Source Experience

Experience across different heat pump technologies can broaden the projects and employers available to an engineer.

Commercial Experience

Larger commercial systems can involve different technical requirements from domestic installations and may require engineers with wider mechanical, controls or building-services knowledge.

Location & Travel

Regional candidate availability, project locations and travel requirements can also influence salary.

​

HEAT PUMP ENGINEER SALARY BY EXPERIENCE

STARTING A CAREER IN LOW-CARBON HEATING

Someone beginning their career as a Heat Pump Engineer may initially work alongside experienced installers while developing practical installation, commissioning and servicing knowledge.

The National Careers Service currently gives approximately £24,000 as its starting salary benchmark.

However, not everyone enters the industry at this level.

An experienced Heating Engineer, Plumber, HVAC Engineer or Mechanical Engineer moving into heat pumps may already possess technical skills that allow them to progress more quickly once the relevant heat-pump knowledge and training have been developed.

​

EXPERIENCED HEAT PUMP ENGINEER SALARY

Experienced engineers can command substantially higher salaries.

The National Careers Service places experienced earnings at approximately £46,000, while Indeed's current market data shows a typical upper range extending beyond £61,000.

Higher earning potential can be associated with:

• Strong heat pump installation experience

• Commissioning capability

• Fault finding and diagnostics

• Servicing and maintenance

• Air source and ground source experience

• Commercial heating knowledge

• Electrical knowledge

• Controls experience

• Supervisory responsibility

• Ability to work independently

• Travel flexibility

As with any engineering role, the overall responsibilities should be considered alongside the headline salary.

​

AIR SOURCE HEAT PUMP ENGINEER SALARY

A GROWING AREA OF HEATING ENGINEERING

Air Source Heat Pump Engineers install, commission, maintain and repair systems that extract heat from outside air and use it for heating and hot water.

Current vacancies illustrate the range available within the market. Recent roles include Heat Pump Engineer positions around £38,000 and Air Source Heat Pump opportunities advertising approximately £35,000–£50,000, depending on experience and employment arrangements.

Responsibilities can include:

• Heat pump installation

• Heating system alterations

• Commissioning

• Fault finding

• Servicing

• Maintenance

• Controls

• Customer handover

• Technical reporting

Professionals with broader heating experience can therefore have a strong foundation for moving into air source heat pump engineering.

​

HEAT PUMP ENGINEER SALARY BY LOCATION

DOES LOCATION AFFECT HEAT PUMP PAY?

Current salary data suggests regional differences, although individual city figures need to be treated cautiously because sample sizes vary.

Indeed currently reports averages of approximately £46,100 in London, £46,200 in Birmingham, £43,800 in Reading, £41,900 in Glasgow and £39,500 in Manchester.

These figures change as vacancies and salary submissions enter the dataset, so they should be used as market indicators rather than permanent regional salary bands.

Location also isn't the only consideration. Engineers covering a wider territory may receive vehicles, travel arrangements or other benefits as part of their overall package.

​

HEAT PUMP ENGINEER VS HEATING ENGINEER

HOW DO THE ROLES DIFFER?

There is considerable overlap between traditional heating engineering and heat pump engineering.

A Heating Engineer may work across boilers, heating systems, pipework, controls and associated equipment.

Heat Pump Engineers specialise further in low-carbon heating technologies, including the installation, commissioning, servicing and maintenance of heat pump systems.

The National Careers Service describes Heat Pump Engineers as professionals who install and service low-carbon central heating and hot-water systems. It also lists Heat Pump Installer, Heat Pump Technician and Low Carbon Heating Technician as alternative job titles.

For experienced heating professionals, heat pumps can therefore represent an extension of existing skills rather than an entirely separate engineering career.

​

CAN HVAC ENGINEERS MOVE INTO HEAT PUMP ENGINEERING?

Yes. This is particularly relevant to HVAC Recruitment's existing candidate market.

Professionals with experience across heating, mechanical systems, controls, commissioning, servicing and fault diagnosis can already possess skills applicable to heat pump engineering.

Potentially transferable backgrounds include:

• Heating Engineer

• HVAC Engineer

• Mechanical Engineer

• Plumbing & Heating Engineer

• Service Engineer

• Commissioning Engineer

• Mechanical Maintenance Engineer

• Controls Engineer

Additional training and heat-pump-specific experience may still be required depending on the position.

For engineers already working across HVAC and building services, however, low-carbon heating provides a logical area for career development.

​

EMPLOYED VS SELF-EMPLOYED HEAT PUMP ENGINEER EARNINGS

Salary figures don't always provide a direct comparison between permanent employees and self-employed engineers.

An employed Heat Pump Engineer package can include:

• Basic salary

• Company vehicle

• Fuel arrangements

• Holiday entitlement

• Pension

• Tools

• Training

• Overtime

• Call-out payments

• Other employee benefits

Self-employed engineers may achieve higher headline earnings but also carry their own business costs and periods without paid work.

These can include:

• Vehicle costs

• Insurance

• Tools

• Training

• Certification

• Holiday

• Pension provision

• Administration

• Tax

• Periods between projects

A self-employed annual income or day rate should therefore not be compared directly with an employed basic salary.

​

HEAT PUMP ENGINEER QUALIFICATIONS & TRAINING

There is no single career route applicable to every Heat Pump Engineer.

The National Careers Service identifies routes including college courses, apprenticeships and moving into heat pumps from related trades. It also lists relevant backgrounds including heating and ventilation, plumbing and domestic heating.

For experienced professionals, training can build on existing heating, plumbing, mechanical or HVAC knowledge.

Employers may consider:

• Existing heating experience

• Plumbing qualifications

• HVAC experience

• Heat pump training

• Air source heat pump experience

• Ground source heat pump experience

• Commissioning knowledge

• Electrical knowledge

• Controls experience

• Manufacturer training

The exact requirements should always be checked against the individual vacancy.
