10 Highly recommended professional
Posted 14 January
Called and arranged the job very promptly. Was able to give a clear indication of what he thought the problem would be and a rough quote during our first call. Arrived on-time and carried out the repair work quickly and professionally. He was able to also inspect my boiler and perform a service on the same day, all while being clear and upfront about the associated costs. Highly recommended, very professional and reasonable.Verified reviewerJob location: SS16Response from Gastech

I asked Gastech around just to quote for a new boiler, he insisted that I didn’t need one, the previous engineer had turned it all off and said it was dangerous, Dean assured me it wasn’t dangerous at all, installed a new pump and valves, cleaned out the header tank, added some chemicals, I’m over the moon, Dean has saved me the best part of £5,000!Verified reviewerJob location: SS6- HHarriet A
