Professional service from the whole team, receptionist, technical support and engineer. Engineer arrived promptly wearing a face mask and gloves. He worked efficiently and tidily. He gave me feedback about what he had done and what he had found. He stood out because of the care he took which left me feeling confident I could trust him in my home which is important. He could not have been more helpful and I have already booked him to do some more work. A professional company fairly priced.

My boiler decided to give up the ghost in lock down... but fortunately AGS Ltd came to my rescue. All the while observing social distancing, they were able to fit a new combi boiler quickly and efficiently, and showing great care to minimise and clear away any mess. Communication was excellent throughout, and I feel that I received excellent value for money. I would highly recommend them to anyone looking for well-qualified gas engineers.

Really impressed with the service from Andy Gas this morning. My boiler had lost pressure and despite having the manual and my brother's advice I couldn’t resolve the problem myself. My mum has had work done by Andy Gas and recommended I ring them. 10 minutes later my boiler is now up and running again. A lovely friendly gent who talked me through it. Many thanks

I found AGS by accident as I needed a repair to an old water heater. Having been quoted in excess of £200 for the job, AGS repaired it for less than £100. I then used them to replace the old heating and hot water system and I found their service to be friendly and extremely professional from the quote to actually doing the job. The guys were very courteous and considerate. They explained everything and kept me informed of the work along the way and answered all my questions. They also took the time to give me instructions on how to use it even though all the instructions were in a booklet. The job was finished in a timely manner and they left my house clean and tidy at the end of every day and I would not hesitate to recommend them

We've used this company for boiler servicing and repairs for a few years now and today their plumber came to sort out a leak in the shower. After being let down, overcharged and generally pee'd off by several other local tradesmen we're happy to reccommend AGS for any work you need done. They're aren't the cheapest (not the dearest either) but they are prompt, pleasant to deal with and completely trustworthy and that's a rarity these days. We even get a Christmas card from them every year.

Annual Service
Used Andy Gas a few times over a couple of years and can't fault them in any respect. Clean, tidy, capable, respectful, efficient and polite. Oh and well priced. Before I got into computing and automation I was a qualified Gas Fitter (some 50yrs ago now) so I have and appreciation of the job and know a good job when I see one.

I had no idea what I needed, but I knew I had to replace my boiler system and increase the water pressure / performance of my showers, hot water etc. AGS guided me expertly through the process, including helping me to choose the most suitable equipment and systems from the many options on the market. They were always on time for meetings, communicated very rapidly, and their presentation and professionalism is outstanding. Once they started work (on exactly the date they had scheduled), the team were fantastic. The house was always immaculate, they cleared up after themselves as they worked, and the standard of their work is amazing - my plumbing is now a work of art :) Nothing was too much trouble. The work was completed on time and on budget (in fact slightly below budget - they gave me a credit) and the finished result is even better than I expected. I would very strongly recommend AGS for any project large or small, they are first-class.

This was our fourth annual boiler service with AGS Ltd and once again their service from booking the appointment via telephone to completion of the task has been excellent. This time Sam turned up and he was early. Friendly yet very professional and efficient. I remarked upon a recent fault and he investigated and soon found the source of the problem. His office was quickly able to supply a favourable quote and the repair work has been booked in. This will be AGS Ltd's last service at my current home as I am moving in a few months. I have already alerted them and asked that they "move" with me to attend to future plumbing and gas requirements at my new property. I cannot recommend AGS Ltd highly enough.

We still haven't got to the bottom of why the controller resets itself to Midnight on 01/01/10 when the boiler is turned off. This results because it was not noticed immediately that the heat is still on at 2.30 in the morning and I have to get out of bed and reset it then when feeling very hot. best wishes.
