Having just completed a conversion of agricultural barn to residential, Terra Therma has been exceptional throughout the project (which otherwise had its ups and downs), completing the underfloor heating, the Mechanical Ventilated Heat Recover system, 2 x Air Source Heat pumps along with the hot water /heating cylinders etc. The guys that come out to do the work, were always friendly, tidy & productive, and the people in the office always helpful. I’d particularly like to thank Mark for his patience and support over the project. I can’t recommend them enough. Simon Nunn
