Fast reponse, great job done
Customer Service
We had problems with our gas boiler, AGW came to assess the issue the following day and gave options as to how to proceed. The boiler was over 10 years old but we were given the option to either make repairs or have the boiler replaced. We were impressed by the thoroughness of the investigation and the speed at which we were able to get the work done. We opted for a new boiler (due to the age of the current system) and were extremely pleased with the work done.

Best we have used, and we’ve tried a lot!
Customer Service
We hired AGW for our cloakroom refit and changing our downstairs radiators. Andy was prompt with his quote, available on the phone and via email and reliable. He helped us choose suitable products and sourced them for us. Andy and his team worked effectively and efficiently. They told me what they were aiming to achieve each day and it was always done. They were polite and tidy. Not the cheapest quote we had but the quality of work was worth the extra.

Prompt and reliable service
Customer Service
Always had prompt and reliable service from Andy and Tim, whether it is installing and servicing a new boiler or removing a broken dishwasher and installing a new replacement.

Thank you for your review.
Boiler installation
Customer Service
We had a new Worcester Bosch gas boiler installed. (We hadn't used AGW before, but were attracted by their customer reviews). Their advice and quote was comprehensive and speedy. The installers did an excellent job, were polite and provided a good walk through the controls. In fact the whole process was hassle free from start to finish! I would have no hesitation in recommending AGW.

Thank you for your review and recommendation.
New boiler, new bathroom and drain repair, three jobs.
Customer Service
1) as part of a house extension we needed to replace an existing boiler. Andy provided very professional advice on the replacement, then worked in close collaboration with the builders to install the new one while extensive building work was ongoing. At the same time, he put in place preparation work for later stages, there was very little disruption and it was a beautifully neat job. 2) At a later stage, Andy and Tim installed the new bathroom items. I was particularly impressed by their attention to detail, a glass basin unit I had sourced separately was found to have minor faults but they strongly advised me to get replacements - four separate replacements before a good one. This is the sort of advice I needed but would not have had such a good result without their encouragement. They advised on design features, installed shower tray, cubicle and radiator, laid the floor, organised wall tiling and finished really nicely. The final result is simply superb. 3) During the building works, a long-standing problem with odour in a separate downstairs cloakroom was finally tackled. This required taking up an existing ceramic tiled floor (the reason it was long-standing), identifying the problem (cracked drain), repairing the broken part, then re-laying a new floor and fully reinstating the cloakroom, as well as installing a new stopcock (original would not turn). In summary, Andy, Tim and team have been very efficient and impressive and I would recommend AGW to anyone.

Excellent workmanship
Customer Service
Andy replaced our 21 year old boiler with combo boiler and fitted some new radiators. He was prompt in providing a quotation and provided a full explanation of what was involved. The work was completed on time and within the budget. Andy is articulate and we were very impressed with the quality workmanship and was tidy when doing the work. Overall it was a good experience throughout the whole process and was impressed with Andy's professionalism.

Speedy service
Customer Service
We woke to our boiler not working, I called Andy at 08:30 he answered the call and was at our house an hour later. Replacement boiler ordered and fitted the next day! Detailed invoice supplied prior to agreeing to proceed. Everything explained in detail and very polite and tidy team. Would recommend.

First class workmanship
Customer Service
AGW GAS LTD have been brilliant. The first call was a water leak on a Saturday at 5 pm AGW came within 10 minutes of my call, dashed to obtain parts and the leak was stopped. Second visit to replace taps, and toilet seats and click and release type sink waste system. Perfect again, clean and completed quickly. Last week our old boiler died. I rang AGW they came the next morning, the boiler had been ordered, was delivered by 10 am and fitted that very afternoon. I cannot recommend it more highly, and the price was much better than I envisaged. A very hardworking, honest and thorough plumber.

Superb service!
Customer Service
My son recently moved into his first property. In typical fashion the old boiler in there decided to pack up and he has had no water or heating for 10 days. Other local plumbers we knew of or who had been recommended to us let us down by not even bothering to return our calls. Having read the list of Which Trusted Traders I decided to call AGW, and I’m so glad I did. My first call, in a real state of desperation, was on Monday afternoon. Andy was courteous and informative and after our conversation and my providing photographs he advised me the best way to sort the problem. I was provided with a detailed quote that I was more than happy with on Tuesday and a call on Wednesday confirmed that a new boiler had been sourced and would be fitted on Thursday. 4 days! Tim turned up promptly on Thursday and worked tidily and demonstrated great expertise, all the while observing social distancing but more than happy to keep us informed of what he was doing. On completion of the installation he took the trouble to explain the boiler and programming controls. Leaving us with the reassurance we could call if we needed any help. Andy also turned up for a short while during the morning to check everything was going ok and we were happy. I have no hesitation in recommending AGW Gas & Plumbing to anybody. They will certainly be my first call for boiler servicing and any other plumbing matters.

New Worcester Combi Boiler
Customer Service
Andy and Tim fitted our new boiler, they were efficient and knowledgeable. The work was carried out to a high standard and our kitchen was left in a clean and tidy state. Being a local trader it’s good to know that they are close by and will call in if we have any problems. I would recommend this company.
