Installation, Commissioning and Servicing of Air Source Heat Pumps OFT21 – 504A

OFT21 – 504A

Heating our homes currently accounts for a huge 13-14% of the UK’s total carbon emissions. An Air Source Heat Pump is a low-carbon way of heating your home. They absorb heat from the outside air and use it to increase the temperature in the home. Air source heat pumps are positioned outdoors, at the side or back of the property and need plenty of space around them for air to circulate.

Success on this course will enable you to become an approved installer, registered on the MCS website. This will enable you to draw down funding for your customers. For more information please see: MCS

This course is for those who wish to install, commission and service Air Source Heat Pumps (non-refrigerant).

The course covers:

  • Health and safety
  • Regional legislation and requirements
  • Safe electrical isolation
  • Factors to be considered before and during installation.
  • Filling and flushing requirements
  • Appliance installation
  • Soundness tests
  • Operational checks and procedures
  • Fault finding, identifying unsafe situations.
  • Practical servicing and commissioning


Applicants must hold a nationally recognised qualification and/ or registration in a trade associated with heating and/ or plumbing work for a period of not less than two years or must have ‘on the job’ heating installation and/ or maintenance experience for a period of not less than two years. Applicants are required to hold current and valid Unvented and Water Regulation certificates.

The course will have a 5-year expiry date.

Low-carbon heat pumps are critical technologies for decarbonising heat. To meet the UK’s legally binding climate targets, thousands more heating engineers will need to learn to install and maintain these technologies. The Heat Training Grant supports trainees in England taking short courses relevant to heat pumps and heat networks. Trainees may receive grants of up to £500 towards eligible courses. The Heat Training Grant is funded by the UK Government. You can find out more about the grant here – Heat Training Grant
