“Daniel and Max designed and installed a new heating system for our house including a biomass boiler, solar thermal and woodburning stove as well as advising on insulation for the house. The design was carefully and thoroughly done and showed an excellent knowledge of renewable energy systems with attention to context, budget and deadlines. The installation was done promptly, with attention to detail, and to an excellent standard. Daniel and Max are extremely professional as well as being tidy and quiet on site, upholding an excellent client relationship.”
