Skilled heat pump installer.
Apprentices learn to plan, select, install, commission, service, and repair zero carbon heating and hot water systems in domestic and small commercial buildings. This includes air source and ground source heat pumps, solar thermal collectors, unvented hot water storage, and the associated pipework, heat emitters, and electrical control systems. The programme covers the scientific principles behind how these systems work, including coefficient of performance (COP), alongside health and safety legislation, sustainability principles, and the regulatory requirements that govern low carbon heating installation and maintenance.
On a typical week, an apprentice will be on site installing heat pump units, running pipework, fitting heat emitters, and wiring up controls and thermostats. They carry out pressure tests, commission completed systems, and walk customers through how to operate them. Maintenance visits involve fault diagnosis using manufacturer tools and test equipment, followed by repair or component replacement. They produce risk assessments and method statements before work starts, and keep records of what was tested, adjusted, or replaced. Work spans new build sites and occupied properties, requiring good communication with customers and other trades.
Completing this standard typically leads to roles such as heat pump engineer, low carbon heating engineer, or renewable systems technician. Experienced technicians often move into supervisory or contracts management positions, or progress towards further qualifications covering larger commercial systems. Employers include specialist renewable energy contractors, national heating and plumbing firms, social housing maintenance providers, and local authority retrofit programmes. Demand is growing steadily as building owners and landlords respond to decarbonisation targets, making this a stable area for long-term employment.
Sorted by achievement rate.
No training providers currently listed for this standard.
Completers typically move into roles such as Low Carbon Heating Technician, Heat Pump Engineer, or Renewable Heating Installer, working across residential and small commercial properties. Day-to-day responsibilities include installing and commissioning air source and ground source heat pump systems, solar thermal collectors, and associated controls, as well as carrying out planned maintenance, fault diagnosis, and repair work. Many work largely independently on site, managing customer handovers and providing operational guidance directly to end users.
Within three to five years, technicians commonly progress to Senior Heat Pump Engineer or Lead Installer, taking on responsibility for more complex systems, mentoring junior colleagues, and overseeing multi-trade installations. Those who prefer a specialist technical track often move into system design, commissioning management, or quality assurance roles. A leadership track can lead to Contracts Manager, Technical Manager, or running a small team within a heating and renewables business. Some technicians build towards self-employment, taking on domestic and light commercial contracts independently.
Most demand comes from specialist renewable energy and building services contractors, M&E (mechanical and electrical) firms, and heating and plumbing businesses that have expanded into low carbon technologies. Social housing providers, local authorities, and energy efficiency retrofit schemes represent a significant share of the public sector market. Housebuilders working on new low-carbon developments also employ technicians directly or through subcontractors. Work spans both rural and urban settings across the UK.
Throughout the programme, the apprentice builds competence in installing, commissioning, servicing and maintaining low carbon heating and hot water systems while working in a real job role. Knowledge, practical skills and workplace behaviours are developed together, covering areas such as heat pump systems, solar thermal, electrical controls, fault diagnosis and health and safety compliance. Before final assessment can begin, the apprentice and employer must confirm readiness at a gateway point, demonstrating that the required knowledge, skills and behaviours have been met. Final assessment then confirms occupational competence. Assessment models for many standards are currently being updated, so check the standard's gov.uk page for the current specification.
Building a strong body of workplace evidence from early in the programme makes the final stages much more manageable. Apprentices should keep records of real tasks as they complete them, including installation, commissioning, fault diagnosis and service work, rather than trying to reconstruct evidence at the end. Regular review meetings with the employer and training provider help identify any gaps in knowledge or skills well before the gateway. Staying organised and honest about where further practice is needed will put an apprentice in the strongest position when readiness is assessed.
Look for providers with practical training facilities that include working heat pump systems, solar thermal rigs and unvented hot water vessels, not just classroom theory. Achievement rates above 65% are a reasonable baseline for a relatively specialist standard; above 75% is strong. Because this occupation sits at the intersection of refrigeration, electrical controls and renewable energy, check whether tutors hold current industry qualifications such as F-Gas, Part P and MCS-recognised credentials. Employer and apprentice satisfaction scores on the FATP profile are worth reading alongside any learner reviews that mention hands-on time versus off-the-job study.
Be cautious of providers whose delivery looks adapted from a general plumbing or gas programme with low carbon content bolted on. If a provider cannot show real heat pump and solar thermal equipment at their training centre, the practical skills in commissioning, fault diagnosis and electrical control systems will be hard to develop properly. Thin or absent learner reviews, vague answers about cohort sizes, or declining achievement rates on a small volume of completions should all prompt further questions. Check whether the provider has current industry partnerships rather than outdated content.
There are no nationally set entry qualifications for this standard, so employers set their own criteria. Candidates typically need a basic level of English and maths, and some employers prefer prior experience in plumbing, heating, or a related trade. Apprentices must be employed for the duration of the programme. If a candidate does not already hold GCSE grade 4 or equivalent in English and maths, they will need to achieve functional skills at level 2 before taking the end-point assessment.
The typical duration is 36 months, but the actual length depends on the apprentice's prior experience and how quickly they develop competence. Apprentices are employed throughout and split their time between on-the-job training with their employer and off-the-job learning with a training provider. The current minimum off-the-job requirement and any duration rules are subject to revision under ongoing reforms, so check the latest specification on the Institute for Apprenticeships and Technical Education pages at gov.uk before planning.
Before taking the end-point assessment, the apprentice must pass through a gateway, at which point the employer and training provider confirm the apprentice has met all the knowledge, skills, and behaviour requirements set out in the standard. Assessment methods for many standards are being updated as part of current reforms, so refer to the current assessment plan on gov.uk for the precise components. The apprentice must demonstrate competence across the full range of duties, from installation and commissioning through to fault diagnosis and repair.
The funding band for this standard is £22,000, which is the maximum that can be drawn from the apprenticeship levy or co-investment arrangement to cover training and assessment costs. Large employers with a levy account use levy funds directly. Smaller employers who do not pay the levy co-invest, contributing 5% of training costs while the government pays the remaining 95%. Employers with fewer than 50 staff taking on an apprentice aged 16 to 18 pay nothing; the government covers the full cost. Wages remain the employer's responsibility.
The role centres on installing, commissioning, servicing, and repairing zero carbon heating and hot water systems, including air source and ground source heat pumps and solar thermal collectors. On a typical day that could mean sizing components for a new installation, carrying out pipework and electrical control connections, testing system performance against commissioning targets, or diagnosing a fault on an existing system. The work spans new build and retrofit projects, often in domestic properties, and involves regular direct contact with customers and other trades on site.
Completing this standard opens routes into senior technician or supervisory roles within heating and building services contractors. Some progress into system design, project management, or energy assessor roles. Others move into related technical areas such as heat network installation or building fabric retrofit. Further qualifications at level 4 and above exist in building services engineering and project management. Given growing demand for heat pump and low carbon heating skills under government decarbonisation targets, qualified technicians are well placed for sustained career development.
