Mullett's have given us excellent service maintaining our church boiler and church hall heaters for many years. Our elderly boiler has been maintained by Iain particularly, and this has extended its useful life by several years. However, response to emergencies is the test of their service. A situation arising in February this year was typical. We realised that the boiler had failed on Friday afternoon. We contacted Mullett's; Iain was with us within 20 minutes, he quickly diagnosed a fan failure and started ringing around to find a supplier. The part arrived at Mullett's office early on Saturday morning, and Iain was in the boilerhouse by 8.00am. The boiler was working later that morning. For service, knowledge and enthusiasm, and standard of work, I would not hesitate to recommend Mullett's
