used gas-tec to replace an old combi boiler for a new one. Ant was great from start to finish. He was able to provide the quote from a few photos i sent him. he had great communication even though i was dealing with him on behalf of my landlords. The quote provided was a very good price and there were no extras added. Ant turned up at the exact time/date arranged and completed the work quickly and professionally, i would highly recommend and will use him for any other plumbing work i need in the future.
