“Doherty Builders have demonstrated great awareness of Eco-Build systems. Their knowledge and implementation of energy efficient “A-Rated” construction methods have enhanced the benefits of our pure energy systems to the end user. Attention to detail particularly in relation to cold bridging, air tightness and insulating methods is outstanding, and demonstrated in heating and hot water costing only £ 2.45/ square meter/ year on a recent public sector building.” Gerry Duffy – Eurotech
