AGW Gas & Plumbing

I recently came downstairs to find my old Potterton boiler leaking water. I immediately phoned this company, who attended within the hour to assess the problem and make the appliance safe. A new boiler was required and I received an estimate the following day for the work required, which I accepted. A new condensing boiler was fitted within 48 hours. The fitters were hard-working, polite, and tidy workers who disposed of the rubbish after finishing the job. I have no hesitation in recommending AGW Gas & Plumbers.

I was very impressed with AGW when I had a boiler problem, Andy was able to fit me in very quickly and sorted it out (blocked condenser), and then when I had a leak from the waste pipe, Tim came and did a great job with the repiping and also gave me very helpful advice. Would definitely use again.

I’m delighted I’ve found AGW - Andy the owner is great ; I don’t think there’s anything he and his team can not do! I’ve just had a lovely new boiler fitted by Tim and his apprentice. Lovely people, extremely knowledgeable, trustworthy, clean & tidy, hard working, very compatible priced and a joy to have around….what more could you want?! I would struggle to use anyone else but Andy in future.

AGW quoted us a great price to re fit our bathroom They were very helpful planning what we wanted. They were very tidy and polite and completed the work on time and within budget. We are really pleased with the bathroom Many thanks

Brilliant response from Andy & Dylan when I had two seperate water escapes. Quickly fitted me into their very busy schedule. I have also used AGW for boiler installation and annual servicing so it's a great all round local service.

Had our old gas boiler removed and a new one fitted in a new location. Andy and the team were quick, clean and professional. Overall they were a pleasure to have in the house, and we couldn't be more pleased with the outcome. Highly recommended. Will definitely use them again.

Super quality, reliable, completing the work on schedule, to a high standard. Pleasant people to have in ones house.

I had my cloakroom refitted by AGW in July and was very pleased with the result. Andy came up with some good ideas to fit the space, with the emphasis being on quality. Everything was installed to a high standard by Tim, who is clearly very competent and experienced. I soon learnt to trust his judgement and he left the room looking very smart and presentable. If you need new cloakroom or bathroom fittings, I recommend this company.

I recently had a new boiler and several radiators installed by AGW. Andy also advised having a power flush and new programmable thermostat. Everything was installed promptly and efficiently by the team. Afterwards, they organised the Guarantee and Gas Safety Certificate on my behalf. I recommend this company to others and will be using them again myself.

Excellent work from Andy and his team as always. Have used them many times and would recommend their work.

Boiler went pop just as the snow arrived made one enquiry and within no time at all an appointment was made. Great clear prompt communication throughout. Assessment made and solutions implemented in no time at all. Amazing knowledge and experience. Can not recommend highly enough. Problem solved and to top it all off great value. A plumber you can trust.

I cannot recommend Andy highly enough. Sorted our central heating and hot water problems out, before spending time giving us advice on boiler replacement or repair on the 13th of February 2023. We went for a replacement. Received his quotation on the evening of the 13th. We made an appointment for Monday 20th. Andy and his mate arrived at 0800 and fitted a new boiler. By 16.00 they had gone having cleaned up, pressure tested the system and given us working instructions. They had removed the old boiler, Hoovered, and left no rubbish at all. The only evidence of them ever being here was a new boiler. After some "plumber" experiences over the last few years. Andy is a revelation. I would recommend him to anyone. Thank you, see you for service in twelve months.

Our boiler was playing, hot water was only lukewarm. Andy replied within minutes to my initial enquiry and gave good support to diagnose the problem. This was followed up the next working day to confirm the problem and a quote received that evening. The work was scheduled and completed a few days later. Tim carried out the installation, arriving just after 8am as agreed. The work was carried out competently and Tim kept me informed of the progress. He took time to fully explain the boiler controls and the smart thermostat. Finally the area was cleaned up, rubbish taken away and he even helped me put the fridge back in place below the new boiler. Why can’t all contractors be this good?

Our boiler gave out during a cold snap. Andy was very responsive and even though he had commitments he managed to come and check our boiler on the same day of contact. He managed to secure a new boiler very quickly and we agreed a reasonable price before the works started, the boiler was fitted the next day. Both Andy and Tim - the engineer who fitted the boiler - were very knowledgeable, professional and friendly. I will definitely be using them in the future for all our gas and plumbing needs. Thank you both so much.

I am absolutely delighted with the refurbishment of my en-suite. Andy was extremely helpful with the planning and selection of fittings, all I had to do was choose the paint colour. Tim and team did a magnificent job; they were professional and obviously experienced with all the tasks involved. All rubbish was removed leaving my house spick and span. I have no hesitation in recommending AGW; it’s a great company.

Fitted a new boiler at short notice as British Gas let me down on a repair to old boiler. Excellent service, very knowledgeable as boiler needed to be moved, fitted boiler in one day, very clean and tidy workmanship.

I was thoroughly pleased with the installation of a new boiler and ancillaries by AGW. They were a pleasure to deal with and the work was completed to a very high standard. What is more the service was friendly, helpful and efficient.

Company came along and gave a quote very quickly for replacement combi boiler and supplied a full written quote for the work and parts needed. The installation went well and all the work was completed within one day. A very efficient and good service with any rubbish removed and area left clean & tidy. A good company to use.Would use them again for plumbing work.

Andy and Tim turned up to complete a boiler install but also move the new boiler downstairs. They were very thorough and kept us informed of what they were doing at all times. Provided a quote prior to work commencing and stuck to that even after going above and beyond to ensure everything was working as it should, before leaving. A fabulous service all round.

From the start, it was a pleasure working with Andy and his reliable team. Andy used his considerable experience to offer thoughtful advice. It was easy to see this was excellent and we followed it fully despite not having worked with the materials suggested before. Tim and Connor were polite and thorough. We were happy to have them around our home as we lived in it too. There were some supply issues which delayed the completion of our modest project but we are very pleased with the finished product. I wouldn’t hesitate to recommend AWG for a bathroom makeover. Thank you!

Boiler condemned on Monday. These guys fitted (and relocated) a new boiler 3 days later, along with upgrading pipework. Courteous, tidy and competitively priced. Will always use them from now on for all my heating and plumbing needs. Just book them!

Tim and team removed a 30 year old plus Baxi boiler from the kitchen and tanks from the loft and replaced with a Worcester Bosch 8000 Style Combi relocated to a walk-in cupboard on landing. This required a new 28mm gas supply pipe and a flue through the roof. They also installed the Bosch EasyControl system and Smart Thermostats to each radiator. An excellent experience throughout and a good team on the job that you can feel very comfortable with in your home. This is the second boiler installation AGW have completed for our family (at different locations) in the space of a month and we are very pleased with both and can highly recommend them to others, with absolute confidence. All work was completed to a very high standard and on time. We felt the cost of both to be very good value for money.

Thank you to Andy & Tim for prompt service from quote to installation in just a few weeks, a new Worcester Bosch boiler ordered (be aware lead time for quality boiler like WB are increasing). Tim installed the boiler in less than a day with very tidy workmanship. Had a few IT niggles with the app based Bosch controller which Tim popped back at very short notice to fix. Very impressed & satisfied, would not hesitate to recommend AGW gas Ltd to anyone who needs boiler replacement or repairs. Thanks again Andy & Tim.

From our first contact with this company to request a quotation to completion of the work I found them very professional and helpful. All members of the team worked very hard and the work was completed on time and my home was left tidy. I would thoroughly recommend this company to anyone considering replacing their boiler or general servicing.

We have two houses in the family that need new boilers and the first of these (my sister's) has been completed by AGW to a very high standard and our complete satisfaction. The new installation required the removal of a failed 20 plus year old Ideal Icos regular boiler and tanks, followed with the installation of a Which Recommended Bosch 8000 combination boiler, to the airing cupboard on the landing (instead of the kitchen). Tim and his team of Stuart and Connor arrived on time and cracked-on with the removal and re-working of the pipework on the first day and completed the entire install by the end of play on the second day. They were extremely professional and courteous and also took great effort to protect her home during the work. They worked with great skill and determination during some pretty hot weather conditions and also some challenging supply issues as well. We have no hesitation in recommending AGW Gas & Plumbing based on our first experience. We are looking forward to having the second install completed and potentially further projects with AGW in both houses to upgrade bathrooms and kitchens, later. My sister is already seeing the benefits of only heating the water she is actually using, just in time to help with the current higher energy costs.

We have known Andy for many years he has always been a professional and reliable tradesman. The schedule was as agreed and the budget was spot on. We would highly recommend this company.

We asked Andy to quote for a new boiler. Within the week he had visited, agreed the boiler we needed (a Worcester as recommended by Which) and provided a quotation. Andy's quotation included a comprehensive list of work required and, based on an on-line search, was competitive with other suppliers. The boiler was supplied and fitted on budget and within a month of our initial enquiry. The team that fitted the boiler turned up exactly on time, were friendly and efficient, completed the work within the time they estimated, explained how everything worked and left the kitchen clean and tidy - taking the old boiler, packaging and debris away with them. I would be happy to recommend AGW Gas and Plumbing.

Job done quickly, cleanly and within the estimate. Fully explained controls, what to look out for and guarantee details. Assured a revisit in the unlikely event of problems.

It's now been a fortnight since our new boiler was fitted and it's performing better than expected. AGW provided excellent service throughout the process when our existing boiler broke down after a botched repair by another plumber. Broke down on the Wednesday evening called AGW on the Thursday quote on the Friday, placed order on the Sunday, boiler sourced on the Monday, Installed on the Wednesday. What can be better than that. Andy and Tim are the A team, a quality bit of pluming.

AGW GAS have just supplied and fitted our new boiler. They were very helpful in advising us and incredibly efficient and prompt with everything throughout the whole process. I would happily recommend them to anyone and wouldn’t hesitate to use them again.

AGW fitted a new boiler, replaced valves on the water tank, drained and refilled the radiators, and left my house tidier than when they started. I originally discussed options with Andy who went through the options in detail. Following agreement Andy sent through the quote quickly. A very reasonable quote! Tim arrived on the agreed day and was shortly joined by Stuart. Tim did the majority of the technical work, ensuring I was informed of what he was doing, and why. At one point he drew a picture so I could better understand, without me asking. Tim appeared unfazed when he had to ask Stuart to pick up more, unforeseen parts. He carefully explained fittings and legislation when doing his work in response to copious questions from me. Tim also explained when he was going to do some noisy work (he knew I was working from home). I've used AGW for some years, having received a personal recommendation from a friend. And I'm really glad they were recommended to me. I am really pleased with the work that Andy and Tim have completed over the years. And the new boiler that they've now installed (and previously the fireplace and all remedial work that they've done over the years). And at a great price. Always with a smile, good humour, and professional conversation. Highly recommended.

AGW did an excellent job of fitting a new boiler and shower. The work was carried out very quickly and efficiently and we cannot recommend them highly enough.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Andy & Tim installed our new gas combi boiler and they did a great job. Prompt, efficient, polite & professional. Would recommend.

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.

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.

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.

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.

Really happy with the service that Andy and Tim provided from quote to finish. Would highly recommend their work. We are very pleased with the Ensuite improvements and our new boiler and WiFi hub.

AGW replaced a very old heat only boiler after it became uneconomical to repair (again!). The quote Andy gave was very competitive, however, we chose to use AGW because they are a local company and because of the recent Which? Trusted Trader reviews they'd received. We were really pleased with the work Tim and Andy did and they took their status as a Trusted Trader very seriously. The work they did was carried out professionally and did the whole job in a day. There were no hidden costs to the quote they looked at what we had, what was required and gave a clear quote for the job and made it clear that that is what we'd pay and it was. We had a couple of problems with the heating after installation because of the way the previous owners had had the house plumbed, but they returned and got this sorted with some good old fashioned humour. I've used AGW a couple more times since the boiler installation and they have always been extremely reliable, turning on the day and time they say and getting the job done without fuss. I have waited a couple of months before writing this and I am now more than happy to unreservedly recommend AGW to anyone looking for a professional and reliable heating engineer - a mate in the trade told me recently that reliable heating engineers are as rare as rocking horse s**t - well here's one - nuff said.

Many thanks to Andy and Tim who on short notice replaced our very old (35+ years) failing boiler. Excellent and efficient service from start to finish of the job. Very pleased and the new boiler is a significant improvement over the old one. Couldn't recommend these guys enough.

AGW replaced our old combi boiler and moved a radiator in one of our bedrooms. Andy visited to quote and emailed the quote later the same day. Date for work was set quickly and all communication was was prompt. Andy’s team arrived on time on agreed day and worked diligently to get the job completed the same day. The team tidied up when they had finished and Andy reassured me to contact him if we had any issues in the future.

Our Boiler finally gave out during recent cold weather on a January Sunday evening, on phoning AGW, our normal boiler service engineer first thing Monday, they arrived by 11.30am and managed to get the boiler operating again, but confirmed that the boiler was on its last legs. We had been informed about this likely situation during it’s annual service some three months previously. A full quotation for a new Worcester boiler was sent to us within two days, which was accepted as it was very competitively priced.The installation was carried out in one day, on a date that suited us, and also with nothing for us to clean or clear away. The New Boiler is a great improvement, and almost silent. AGW are extremely pleasant to deal and very efficient, we would not hesitate it recommending them.

Andy and Tim are very knowledgeable and experienced. We were having an urgent replacement of a 23 year old Potterton gas boiler by the latest Worcester-Bosch. We'd had an earlier quote by a well known local rival, but were not impressed by his method. Andy's quote was higher than his, but justified by his advice for a higher power model of the boiler, a replacement of the pump, etc. -- and why. Andy sticks to his quote and his thorough list of what he will do, whereas the other man expected us to sign a legal document with a long list of legal clauses, after a very vague list of what he was going to do. The whole complex job was started at 8am and was done by 4.30pm. Not cheap, but good value.

Excellent service & workmanship from Andy & Tim once again. More than happy with new boiler fitment.

Andrew and his team acted professionally throughout... from initial contact to completion. The price paid was the price on the initial quote. They even replaced pipework to an outside tap as it looked unsightly, with no extra charge. The new boiler was moved to a new location with minimal fuss. The team were considerate of their surroundings and cleared up after themselves. I wouldn't hesitate to engage their services again and would recommend them highly to others.

We are newcomers to UK, and the boiler in our recently bought house broke down. From start to finish the service and attention was just brilliant. We are very pleased with the timing, work, attention to detail and of course Andy and Tim. Thank you

Perfectly done. All the work was completed on time and we're very pleased with the outcome. All in all an excellent job.

AGW Gas & Plumbing recently installed a new central heating boiler in a 4 bedroom house. They assisted us in the selection of the boiler and provided a very competitive quotation for the boiler and installation. They arrived on time and undertook the work within one day. During the process they were tidy and careful not to cause any unnecessary disruption. We are delighted with their work and have no hesitation in recommending AGW to future customers. You can be confident that this company will look after your interests and not overcharge for their services.

Andrew has worked on my property several times over the past 10 years. He and his team has always carried out work to a very high standard and at a reasonable price. I would not go to anyone else. Bob Winkworth

Always a prompt and efficient service from Andy and his team. Great customer service and aftercare. Customer, North Somerset

Right from my first enquiry Andy was really helpful. I needed a new boiler and was struggling to decide but he took the time to explain what I needed to know to make my decision. The new boiler was fitted yesterday by Andy and Tim who did a great job. They are both very friendly but still professional and took care to leave everything clean and tidy. I'm very happy to recommend AGW.

Totally reliable and excellent workmanship. Every job is done properly. AGW know what they're doing and do the job right - no shortcuts. Whether it's a minor plumbing job or designing and installing a bathroom, you can trust them to deliver real value and a finished project that is first class

We have been using Andy at AGW Gas for years now. His work is always of a great standard. You know he is not going to 'rip you off' and you'll get a quality job.

I contacted AGW when my heating stopped working. Andy arrived that same day and had it up & running in no time! I will now be using AGW for my boiler services & I would definitely recommend them to friends.

All completed by Andy and his crew to an excellent standard and very quickly. A great team to have working for you. Would highly recommend if you want a large or small job done properly and quickly.

Really pleased with the work done by Tim & Ryan which involved moving my boiler. Tim explained everything he was doing, I had made a couple of requests and he explained what he would to achieve this. Both of them were professional and friendly, great to see a local company taking on and training an apprentice (Ryan). Andrew easy to deal with, responded quickly with quote and start date once I agreed.

Andy and his team have been looking after my rental property for years in terms of plumbing requirements and I recently had central heating and bathroom modifications completed in my own house which I asked Andy to do. The service, professionalism and competency of Andy and team are absolutely first class. Andy undertook a site survey on the same day I contacted him about the recent work and less than one week later the team was sorting all of my plumbing modifications to adapt my existing house to a rear extension, plus installation of 7 radiators, all in half a day. The quality of service I received from AGW is such a rare commodity in the U.K. Thoroughly recommended for any plumbing scenario. Thank you very much indeed.

I found Andy on this site and am glad I did. He responded amazingly quickly to my 'emergency' call-out to fix a non-working Greenstar boiler and identified the fault (blocked condensate outlet) immediately. And he gave a lot of sound advice on how to avoid a repeat experience. Not least of course to have the boiler serviced regularly. He will get my businees in future because his charges are reasonable and he gives confidence that he will do the work properly (unlike, seemingly, the last - Bristol based - CH 'engineer' employed to give my boiler a service!).

I have known Andy for a few years now and he has carried out several jobs for me. Andy and his team, Tim and apprentice Ryan work hard and to a very high standard. They are totally reliable and good with ideas, suggestions and solutions. This week the team have refitted my heating system (new piping, radiators and controller). Very pleased with the work done. Very neat and tidy. I think Andy offers good value for money. I would not hesitate to recommend AGW Gas & Plumbing Services.

I called AGW and Andy visited the next day to assess our faulty boiler. A quote for repair or replacement was emailed to us the same day. We chose to replace the boiler as we found the quote to be very reasonable. Within 4 days we were booked in for the replacement and a new boiler was on its way. Andy explained our heating system thoroughly and the whole quotation and works to be carried out. Both Tim and Andy were here prompt on the day and completed the installation with the minimum of disruption and even got our gas and water back on within a few hours. All the rubbish was taken away and the house left clean and tidy as they had brought their own dust sheets to cover our carpeted stair runner. I wouldn't hesitate to recommend their services and relieved to of found such a reliable and efficient company for our future gas and plumbing needs. Thank you both.

Called AGW on Saturday regarding a leaking toilet pedestal and two radiator valves that needed replacing. The chaps were round first thing Monday morning and did a top class job. They were courteous, worked hard and left everything neat and tidy.
