Report
A fantastic, informative and knowledgeable engineer came to service my boiler today from Heat GB, and I cannot praise the work and work ethic highly enough. A really fantastic service from a company that I didn't even know existed. I would not only recommend both the engineer and this company, I would drive them round to your house so that you could see how it's supposed to be done. Really impressed. Adam.
