What does a Heating engineer do?
A heating engineer installs, maintains, and repairs heating systems such as boilers, radiators, and underfloor heating. They make sure your system runs safely, efficiently, and keeps your home warm all year round. From new installations to fault finding and servicing, a heating engineer helps keep everything working as it should.
