    "Mark has completed several jobs for me and my family. He is an excellent heating engineer. His last job was to relocate and install a new boiler in the loft. Later to fit underfloor heating in a kitchen extension. He has always been reliable and the quality of work has been excellent."

    "I can’t upload an image, as the latest work was on small parts within a gas appliance. But over the years, Mark has done several jobs for us, large and small, and he is always first point of call."

    "Mark previously installed my boiler and replaced a radiator in 2016. Since then I've used him for multiple jobs including fitting new bathroom taps, and a toilet. I also have an annual service from him, and he has come out to fix a leak as well. Mark is always punctual, polite and professional. I also asked him to fit a new floor when he installed the new toilet which he did expertly."

    "Mark and his apprentice were friendly, professional and efficient. They arrived punctually, did a great job fitting a shower and left the place tidy. I’ve already recommended them to friends who are equally satisfied."
