Fantastic service
Customer Service
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.

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.

Boiler Replacement
Customer Service
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?

Replacement Boiler - highly recommend
Customer Service
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.

Great job!
Customer Service
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.

Customer Service
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.

New boiler replacement
Customer Service
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.

New boiler
Customer Service
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.

Worth trusting indeed!
Customer Service
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!
