    Gas Boiler Servicing / Repair

    Posted 2 days ago

    Amazing service

    Excellent service from start to finish. The engineer arrived on time, was professional, friendly, and carried out a thorough boiler service, including cleaning the magnetic filter. They explained everything clearly, worked efficiently, and left the area spotless afterwards. It’s reassuring to know the heating system has been properly maintained. I would definitely recommend their services to anyone looking for a reliable and knowledgeable heating engineer, and I’ll happily use them again in the future.

    Gas Boiler Installation

    Posted 2 days ago

    Recommend 100%

    Fixing a new boiler and servicing our whole heating system in our five-room detached house. The work went very smoothly, with accurate timing and willingness to accommodate any requests. The team was very polite and professional. It's rare to find a team that works in our house like that.

    Emergency Plumber Service

    Posted 15 July

    Quick and professional service

    Emergency plumbing needed to deal with a shower issue. Issue was resolved pending new parts and the shower was made safely usable in the meantime, with clear information and help provided throughout. The plumber identified the issue quickly and gave practical demonstrations of what to do, and tested it several times to make sure the solution would work. Good, quick and professional service - recommended and would use again. Reasonable and fairly priced.

    Gas Boiler Servicing / Repair

    Posted 22 June

    Fantastic service - would recommend highly

    I recently hired A1 to assist with a boiler that was overpressurising. From the outset they were extremely good at explaining what the probably cause of the issue was and how much potential replacement parts would be. They asked for everything they needed very quickly. They came out within a couple of days and were very friendly on site. After confirming the issue, they ordered the parts and came round very quickly to sort out the issue. They even took a quick look at my washing machine that had gone wrong and sorted it out. Very friendly all around. Very highly recommend!
