Air source heat pump courses provide accredited training for professionals aiming to install, design, and maintain renewable heating systems. With rising demand in the UK due to government incentives and decarbonisation targets, these courses are now essential for heating engineers, plumbers, and technicians who want to upskill and future-proof their careers.
What Are Air Source Heat Pumps (ASHPs)?
Air Source Heat Pumps (ASHPs) transfer heat from outdoor air into buildings to provide heating and hot water. They are central to the UK’s net-zero energy strategy and a fast-growing alternative to gas boilers.
How Do Air Source Heat Pumps Work?
ASHPs use refrigerant circuits to absorb low-temperature heat from outside air, compress it, and release higher-temperature heat indoors. The process is efficient and works even in colder weather.
Key Components – Refrigerant Circuits, Compressors, Heat Emitters
The main components include:
- Evaporator – extracts heat from outside air.
- Compressor – increases refrigerant pressure and temperature.
- Condenser – transfers heat into radiators or underfloor systems.
- Expansion valve – regulates refrigerant flow.
Benefits of ASHPs for Homes and Businesses
ASHPs reduce carbon emissions, lower running costs, and qualify for financial incentives. Businesses installing them improve sustainability credentials and meet regulatory requirements.

Why Take an Air Source Heat Pump Course?
Heat pump training prepares professionals to handle design, installation, and maintenance of ASHP systems while ensuring compliance with industry standards.
Career Benefits for Heating Engineers and Installers
Engineers who train in ASHPs expand their service offering, attract eco-conscious clients, and increase earning potential.
Meeting UK Decarbonisation Targets and Regulations
The UK government plans to install 600,000 heat pumps annually by 2028. Trained professionals are vital to meeting this target.
Access to Government Grants and Incentives
Only accredited installers can deliver systems eligible for schemes like the Boiler Upgrade Scheme (BUS). Training unlocks access to these opportunities.
Types of Air Source Heat Pump Courses in the UK
Training programmes vary by level of expertise, from beginners to experienced installers.
Beginner Courses – Introduction to Heat Pump Systems
Ideal for professionals new to renewable heating, these courses cover ASHP basics, system design principles, and safe installation practices.
Advanced Courses – System Design, Heat Loss Calculations, and Sizing
Advanced modules teach complex skills such as calculating heat loss, selecting correct system sizes, and integrating with hot water and low-temperature heating systems.
Short CPD Training vs. Full Qualifications
CPD (Continuing Professional Development) courses refresh existing knowledge, while full qualifications (e.g., City & Guilds, MCS) provide industry-recognised certification.
