What it takes

Skills and knowledge

You'll need:

  • the ability to use, repair and maintain machines and tools
  • knowledge of building and construction
  • to be thorough and pay attention to detail
  • design skills and knowledge
  • knowledge of maths
  • the ability to work well with others
  • the ability to use your initiative
  • customer service skills
  • to be able to carry out basic tasks on a computer or hand-held device

Most relevant

  • Physics - Heat pump engineers need to understand thermodynamics – how heat energy is transferred between environments – which is the core principle behind how heat pumps work. They also apply knowledge of fluid dynamics, pressure, and electrical circuits when installing and diagnosing faults in heating systems.
  • Mathematics - Heat pump engineers calculate heat loads, pipe sizes, flow rates, and electrical requirements to make sure systems are correctly sized for each building. They also read technical drawings and work out material quantities when planning installations.
  • Design and Technology - Heat pump engineers work with tools, pipework, and components, and need to read technical plans to figure out how systems fit into a building. Practical problem-solving skills and understanding how materials and structures work together are essential for every installation.
  • Engineering - Heat pump engineers install and maintain complex mechanical and electrical systems that move heat energy around buildings. Understanding engineering principles like system design, fluid mechanics, and control systems helps them install reliable, efficient heating setups.

Also relevant

  • Environmental Science - Heat pump engineers work at the forefront of the transition to low carbon heating, helping reduce buildings' reliance on fossil fuels. Understanding how energy use affects the environment and why renewable technologies matter gives context to the work they do every day.
  • Electronics - Heat pump engineers work with electronic control panels, sensors, and thermostats that regulate how heating systems operate. Understanding how electronic circuits and components function helps when wiring up, configuring, and troubleshooting these controls.
  • Chemistry - Heat pump engineers work with refrigerants – the chemicals that absorb and release heat as they cycle through the system. Understanding how these substances change state and behave under different pressures is important for safe handling and system efficiency.
  • Business - Heat pump engineers often set up their own businesses or work as self-employed contractors. Understanding how to price jobs, manage finances, and build good customer relationships is important for those who want to run their own operation.

How to become

You can get into this job through:

  • a college course
  • an apprenticeship
  • working towards this role

You could take a college course in a related subject like plumbing and heating, or a T Level in Building Services Engineering for Construction.

These courses teach you some of the skills you'll need to apply for a trainee plumber, heating and ventilation engineer, or gas service technician position with a company.

Once you've built up your experience, you could take extra training, usually lasting between 3 and 5 days.

This would include:

  • heat pump foundation knowledge
  • low temperature heating and hot water systems
  • individual heat pump technology

Entry requirements

Entry requirements for these courses vary.

  • 4 or 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths for a T Level

More Information

You could apply to do a Low Carbon Heating Technician Level 3 Advanced Apprenticeship to become a heat pump engineer.

You could also do a Heat Network Maintenance Technician Level 3 Advanced Apprenticeship.

These take around 3 years to complete.

Entry requirements

You'll usually need:

  • 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths, for an advanced apprenticeship

More Information

You could train as a gas service technician, heating and ventilation engineer or plumber. You could then do additional training to become a heat pump engineer.

Training would cover:

  • low temperature heating and hot water systems
  • heat pump installation and maintenance
  • different types of heat pump technologies

Lots of organisations offer training in heat pump installation. You can search for heat training providers in your local region.

Professional and industry bodies

You could join the Heat Pump Association (HPA) for professional development opportunities.
