"High praise for this business. We had a 14-year old oil fired boiler which packed up. The response we had was exceptional both in regards to the time it took to arrive on site, the thoroughness of fault finding, and speed at which the repair was carried out. Josh knows his business. Explanation, communication and customer care were first rate. Clearly a perfectionist. Highly recommended."
