Posted on David WalkerTrustindex verifies that the original source of the review is Google. I was very impressed with this company. They came to service my boiler through a recommendation and will definitely be using them again. Knowledgeable and friendly. They also spotted a problem but said my boiler may still be under warranty (which it was) saving me a nasty repair bill just before christmas!Posted on Patrick CTrustindex verifies that the original source of the review is Google. Great service. I’ve used them a number of times now. They always arrive on time. This last job they fixed three issues around the flat including fixing a leak in the flat above and done within the hour. Highly recommend.Posted on Lan-Anh BuiTrustindex verifies that the original source of the review is Google. Used AS Plumbing And Gas to do boiler check and gas certificate. Great communication and open pricing. Was in contact by messages on a trader search site then by emails. They also called to let me know when they were on way as requested. It's always hard finding reliable and trustworthy trades so was pleased this experience turned out well, they'll be our go-to plumber/gas engineer.Posted on Julie BakerTrustindex verifies that the original source of the review is Google. Brilliant! Never felt like using that word with any other people or company doing plumbing and boiler work and I’ve used quite a few over the years. Very professional, knowledgeable, reliable, helpful, polite, friendly & cheerful. Thoroughly recommend. Boiler serviced followed by power flush, new pump & thermostatic valves fitted to radiators which made great improvement & year later just had another annual boiler service & all very fine.Posted on Alex STrustindex verifies that the original source of the review is Google. I've had AS Plumbing and Gas come to mine for my radiators and boiler and there were very professional and helpful! Alfie did a great job installing my new radiator and did a flush of the whole system. Al installed my boiler and gave me lots of advice as well! Excellent lads, they're a good laugh too. Ashley's customer service is impeccable too. She was very accommodating when we got the appointment booked. She got back to me promptly with a very competitive quote and answered my questions. Great team all round. Will use again, thank you!Posted on Mark MccartneyTrustindex verifies that the original source of the review is Google.

If you’re looking for reliable and trustworthy plumbers, Al and Alfie are the go to guys.Posted on Joe WalkerTrustindex verifies that the original source of the review is Google. Al and Alfie are a really great find - honest, reliable, fair, experts. We had a new boiler fitted for which they gave great advice, offered us a really competitive price, and completed all the work in a couple of days (switch to combi). Would highly recommend and will be using for future work.Posted on Steve PattersonTrustindex verifies that the original source of the review is Google.
