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.

Highly recommended
Customer Service
Andy and Tim have done an excellent job replacing my old Potterton boiler and Boilermate tank with a much more efficient and controllable system and it only took 2 days, as Andy said it would. I'm really pleased with it all and they were a pleasure to have in the house. Not only were they very efficient and cheerful but also very mindful of lockdown safety. They're a great team and I've already been recommending them to friends.

I would recommend AGW wholeheartedly after the immediate response and repairs undertaken at my elderly stepmother's property. Really appreciated the quality of the work and customer care.

Boiler installation that flue by
Customer Service
It started well and stayed that way - Andy was there to see the work start and then left his 'experts' to get on with it. I've never seen such well turned out fitters before - and their work was all done in a calm and measured way - very reassuring. They even had the bandwidth to apply their skills to resolve a domestic emergency which unfolded while they were on site - thanks lads. And those of us that appreciate neat pipe soldering were treated to a masterclass. There was little trace of them having been in the house, when they left - aside from a lovely new boiler. Just as well as that's what we were expecting. AGW a firm recommendation then.

New boiler installation

Andy and Tim are a great team; very professional and totally reliable. A detailed and competitive quote was promptly provided and I was pleased to be able to use a well respected local company. All work was completed well within the estimated time scale and the house was left clean and tidy. Thank you both. I would thoroughly recommend AGW Gas for heating and plumbing services.

A very good local firm.
Customer Service
Had a new boiler installed. Tim arrived on time and worked cleanly and respectfully throughout the day. Answered all my questions thoughtfully and with understanding. Thoroughly cleaned up afterwards, removed all rubbish and old boiler and left my home as he found it. Warranty registration documents and building regs certificate have arrived promptly. Andy & Tim run a very good local firm which I am happy to recommend. Portishead resident.
