Worcester Bosch Boiler Installation
Customer Service
Quality
Value
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.

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.

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.

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.
