Domestic Boiler Installation Courses in the UK

Boiler installation remains a core heating trade, but the shift to heat pumps means gas engineers are upskilling. This guide covers the route and the transition.

Last reviewed: August 2026

The gas route

Domestic boiler installation requires Gas Safe registration via ACS qualifications. Many engineers then add heat pump awards to stay relevant as the Boiler Upgrade Scheme and Warm Homes Plan drive heat pump uptake.

Transition to heat pumps

Gas engineers are ideally placed to retrain as heat pump installers — they already understand wet central heating. Add an MCS-recognised Level 3 heat pump award + WRAS.

FAQs

Can a gas engineer install heat pumps?
Yes, with an MCS-recognised heat pump award and Water Regulations; gas experience is a strong foundation.
