Do you need to be certified to fit an air source heat pump?

Yes. You need an MCS-recognised Level 3 qualification (e.g. LCL Awards or BPEC) to install heat pumps that qualify for government incentives.

How long is an air source heat pump course?

Most are 3 days with a practical and theory assessment. Some providers offer 2.5-day formats.

Is there a free heat pump installer course?

Some manufacturers and Skills Bootcamps offer funded or free training. Paid open courses typically cost £500–£700 + VAT.

Air Source Heat Pump Courses in the UK

Air source heat pumps (ASHPs) are the UK government's primary low-carbon heating technology, with a target of 600,000 installations a year by 2028. Trained, MCS-certified installers are in short supply — which makes ASHP training one of the highest-demand energy efficiency qualifications. This guide covers what the course involves, what it costs, and how to get certified.

What the course covers

A typical Level 3 Award in the Installation and Maintenance of Air Source Heat Pump Systems (non-refrigerant circuits) teaches design, survey, installation, commissioning and fault-finding for domestic systems up to 16kW. Providers include GTEC, Logic4training, Skills Training Group and BPEC. Courses run ~3 days and include a practical assessment plus multiple-choice theory test.

Cost and funding

Paid courses cost roughly £585 + VAT (e.g. Logic4training, 2026). Funded and free routes exist: some manufacturers (e.g. Alto Energy) run free installer training, and Skills Bootcamps can cover most or all of the cost for eligible learners. Always check whether a provider is recognised by MCS before booking.

MCS and why it matters

To join the Microgeneration Certification Scheme and install heat pumps that qualify for government incentives, you need an MCS-recognised qualification. The LCL Awards and BPEC Level 3 awards are accepted. You will also typically need the WRAS Water Regulations qualification for install-only registration.

Career outcome

MCS-certified ASHP installers command strong rates as demand outstrips supply. Many progress to designer status (requiring a low-temperature heating qualification or a contract with a qualified designer).
