After the initial phone call a very early date was agreed upon to supply and fit a new Combi Boiler . The fitter arrived on time with all the necessary tools to complete the job . The job was completed in the allotted time with all the area left clean and tidy . A small problem occurred a few days after fitting but that was sorted the day that it was identified . So very happy with the whole experience .

Having used AGW for a number of jobs over the past few years, they have recently replaced our boiler. Great communication throughout, all aspects of the job were completed professionally, managing to design a solution that minimised disruption to our existing installation. Thoroughly recommend.

This company found clever solutions to deliver all the requirements we had for a new shower room/cloakroom in a very very small space. They worked promptly and to budget and were considerate and tidy. We now have an amazing shower room/cloakroom. We would call on AGW again and are happy to recommend them.

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.

AGW have modernized and refitted 3 bathrooms for us, fitted a number of new radiators throughout the house and replaced our gas boiler, hot water cylinder and all valves and the pump. All their work was completed on budget and on time with zero mess left behind. An excellent company with a top team of professionals.

Andy has done a variety of work for us over nearly 10 years. Bathroom, En suite, kitchen remodel and plumbing including a new boiler. Has a can do approach and is up to date with the latest developments in his field. One of his great strengths is an eye for designing installations. He is able to suggest ways of achieving the desired outcome that perhaps had not been considered. It’s always been a pleasure to deal with him, Tim and also now Ben.

Emergency Boiler Replacement

I’d contacted a couple of local firms after my boiler are provider let me down following a boiler. A couple didn’t return my calls and another was busy for a few days. I had no hot water and heating so Andy kindly agreed to attend my property and check the boiler on the day I rang. Whilst the boiler was beyond repair he quoted me for a good quality boiler and some associated work within a day of attending which I was really impressed with. His team replaced the boiler the following week and everything was completed to a high standard. Excellent and honest response and I would highly recommend.
