installation of combi boiler
Customer Service
They removed the old gas boiler etc. from the airing cupboard and installed a combi boiler. They fitted new thermostat valves on all the radiators. They removed all the rubbish from the site. They were hard working and polite and tried to keep things as tidy as they could, putting sheeting down the stairs etc. We were happy with the estimate, and they took two days to do it all. They took their time to explain to me how to work the new system. There were a couple of issues which needed attention afterwards and they came back without hesitation to fix it.

Thank you for taking the time to review our services, it is much appreciated.
Helpful and Reliable company.
Customer Service
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.

Boiler error message
Customer Service
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.

Boiler replacement - Fantastic!
Customer Service
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.

Quick response.
Customer Service
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.

New Cloakroom
Customer Service
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.

A friendly and professional service
Customer Service
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.
