Engin, of Boiler Bunny, was very courteous, and he explained the steps that he undertook while he was performing the annual service of my Worchester Bosch gas boiler. He also provided photos of his work. He recommended a few items that would prolong the life of my boiler and keep it running as efficiently as possible. He also verified that the radiators and thermostat were functioning correctly, and he checked the gas meter as well. Engin was polite, well-mannered and, professional and I would hire his services again in the future.
