    Old leaking/broken boiler replaced quickly, efficiently and with very little mess.

    Posted 14 February

    David came to our assistance on a cold dark evening when the boiler started to leak. He was there within minutes. From the very start his professional approach and commitment to providing a first class service were obvious. As he fixed one fault however another would spring up. We decided that owing to the age of the boiler a replacement was a better option. Very quickly the new boiler was fitted, up and running, with better, neater pipe work and very little mess. Would I recommend him, most certainly. 5 star service.

    Reliable and efficient engineer

    Posted 19 December 2025

    Dave is a thorough & knowledgeable engineer; he recently replaced all our radiators ensuring they each were correct sizes for individual rooms. He completely flushed the system out to increase the efficiency & also serviced the boiler. Dave replaced & upgraded our downstairs cloakroom also; giving advice regarding new bathroom furniture.
