I had an issue with hot water provision through my house. The team at Weiss was very helpful since the initial call and... managed to get an appointment scheduled on the same day. Gadi was incredibly kind and helpful, and not only identified and repaired the issue promptly, but also took time to explain me the system and provide some very sensible recommendations. 5 stars service from a very happy customer.read more

I engaged the services to fix an old-style toilet flush (one of those with a handle and siphon). I explained the... problem clearly over the phone and they sent engineer out same day and obviously charged their call out rate in advance (£114). The plumber spent literally 5mins looking at the flush and announced it can't be fixed and will need spare parts, for which they will send me new quote for parts and charge again for labour/effort. Given the urgency, I felt they could have done a better job of bringing the part and solving the problem in one go or not intended to charge me again for labour/effort on 2nd visit given the first visit was so short. I completely understand the point of call-out charge, but this is the whole idea of providing good customer service. I never heard back from Gas Weiss, went elsewhere and got it fixed for a reasonable price.They have now lost me as a future customer. Hope Gas Weiss can understand that they will make a lot more money from repeat and loyal customers, who must be won with great customer service.read more

Bad attitude and customer service.First engineer that visited was very helpful. He was polite and in uniform. The... second however was just plain rude. Came in casual clothes holding a broken bucket. No introduction, nothing. Have to be careful who you let into your house. I asked to see some ID and he got all stroppy. His van was parked a way down the road so I didn't see it. When I saw the van, I said that's proof enough for me. But already in a bad mood, he now couldn't find any ID and shouted at me that since he can't find it he's leaving. And he drove off.The company didn't follow up. Didn't hear a thing from them. Needless to say, I went elsewhereread more

Very Happy we had a problem with the control of our central heating. The heating engineer quickly identified the... problem was with the programable controller. He replaced it quickly and efficiently and checked the rest of the system. He explained how to use the new controller and advised us on how to run our system better. He was charming and easy to talk to. We will use this company whenever we have a fault with the heating.read more

After a challenging couple of days with a blocked kitchen sink and a grumbling boiler (so no hot water or central... heating), I finally called Gas Weiss. Within ten minutes, (not the two hours guaranteed by the office), two highly competent plumbers arrived and sorted both problems out, which turned out to be inter-related . They were clean, tidy, reassuring and knowledgeable. I am very happy to recommend this company.read more

The service itself was great, but unblocking a sink for £102 is beyond rediculous. As that is just the call out fee,... it's lucky no extra work was needed for such a price during hard times. The boy that came however was very covid conscious, polite and did a wonderful job.read more

I didn’t use this company for their plumbing skills but thought I should give them a review anyway. A member of their... staff (Matt) was very helpful to me when he saw with a flat tyre while he was out on a job. I was stuck and couldn’t get to work so he asked if I was ok and changed my tyre over for me. I think This says a lot about the type of people who work for this company and would recommend them highly.read more
