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.

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.

Replacement boiler
Customer Service

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.

Worcester Bosch Boiler Installation

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.

Worcester Bosch 8000 Style Installation - 100% Satisfaction
Customer Service

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.

We have used Andy for our heating and plumbing needs for over 12 years and always find the quality of the service outstanding. Ben and Tim came to us this time, they installed and commissioned a new boiler and also replaced a built in shower. They were polite, efficient and very tidy and the work was completed in a single day, we had no mess to clear up afterwards. As usual, a five star service from AGW Gas and Heating.

We’re delighted to hear that Ben and Tim provided the same high standard of service you’ve come to expect, and that you were pleased with the new boiler and shower installation. Thanks again for taking the time to leave us a great review!
New Cloakroom

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 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.

10 Radiators replaced with great results and minimum fuss

Following a recent boiler upgrade, we now wanted to improve on both the look and efficiency of existing 30-year-old plus, radiators. We knew roughly the style we wanted so with Andy's help to make sure they were of the right size and specification for our system, we booked an installation date. Tim and Ben did the work to a very high standard and we are very satisfied with the outcome. Installation was carried out with minimum fuss and completed on the day arranged. Having also used them for two previous boiler upgrades in family properties, we can highly recommend the services of AGW Gas & Plumbing Services and have found them to be honest, diligent and competitively priced.

Great work by AGW! The old boiler and radiators were taken away, and new ones were fitted. New water pipes, gas pipes and vents. Tim and Ben did a great job, and our house is much warmer than before. It was a very professional job, and we are delighted with the end result. Many thanks, Andy, Tim and Ben.

Central Heating Boiler replacement

We have engaged AGW for all our plumbing and central heating needs for many years now. They are experts in their field and we have never had cause to complain. Not only do they work efficiently, but they also explain everything carefully, are unfailingly polite and never leave a mess, putting protective coverings down where necessary and removing all replaced parts and equipment. The current job was done within a few days of AGW diagnosing the problem during a routine boiler service. The replacement of our boiler took only a few hours. It was, as ever, a pleasure to do business with AGW.
