Boiler not holding pressure
Really great service. He arrived quickly and was very efficient with the job. Gave solid, practical advice and managed to work around some awkward access without any issues. Everything was sorted properly and at a very reasonable cost. Would definitely use again and highly recommend.Job location: AB11RChris S10 Gas Boiler Servicing / Repair

Leak in boiler (was advised by British Gas engineer that the fault was a cracked sump)
Very pleased with the responsiveness from mark at M.A.S gas services. As soon as he took the front panel off the boiler he immediately advised the sump was not in fact cracked at all and pointed out it was a faulty washer in a water pipe coming from the boiler which he fixed promptlyVerified reviewerJob location: AB21RAlan F
