Boiler installation that flue by
Customer Service
It started well and stayed that way - Andy was there to see the work start and then left his 'experts' to get on with it. I've never seen such well turned out fitters before - and their work was all done in a calm and measured way - very reassuring. They even had the bandwidth to apply their skills to resolve a domestic emergency which unfolded while they were on site - thanks lads. And those of us that appreciate neat pipe soldering were treated to a masterclass. There was little trace of them having been in the house, when they left - aside from a lovely new boiler. Just as well as that's what we were expecting. AGW a firm recommendation then.

New boiler installation
Customer Service
Andy and Tim are a great team; very professional and totally reliable. A detailed and competitive quote was promptly provided and I was pleased to be able to use a well respected local company. All work was completed well within the estimated time scale and the house was left clean and tidy. Thank you both. I would thoroughly recommend AGW Gas for heating and plumbing services.

A very good local firm.
Customer Service
Had a new boiler installed. Tim arrived on time and worked cleanly and respectfully throughout the day. Answered all my questions thoughtfully and with understanding. Thoroughly cleaned up afterwards, removed all rubbish and old boiler and left my home as he found it. Warranty registration documents and building regs certificate have arrived promptly. Andy & Tim run a very good local firm which I am happy to recommend. Portishead resident.

Replacement boiler installation
Customer Service
AGW replaced a very old heat only boiler after it became uneconomical to repair (again!). The quote Andy gave was very competitive, however, we chose to use AGW because they are a local company and because of the recent Which? Trusted Trader reviews they'd received. We were really pleased with the work Tim and Andy did and they took their status as a Trusted Trader very seriously. The work they did was carried out professionally and did the whole job in a day. There were no hidden costs to the quote they looked at what we had, what was required and gave a clear quote for the job and made it clear that that is what we'd pay and it was. We had a couple of problems with the heating after installation because of the way the previous owners had had the house plumbed, but they returned and got this sorted with some good old fashioned humour. I've used AGW a couple more times since the boiler installation and they have always been extremely reliable, turning on the day and time they say and getting the job done without fuss. I have waited a couple of months before writing this and I am now more than happy to unreservedly recommend AGW to anyone looking for a professional and reliable heating engineer - a mate in the trade told me recently that reliable heating engineers are as rare as rocking horse s**t - well here's one - nuff said.

New combi boiler
Customer Service
Many thanks to Andy and Tim who on short notice replaced our very old (35+ years) failing boiler. Excellent and efficient service from start to finish of the job. Very pleased and the new boiler is a significant improvement over the old one. Couldn't recommend these guys enough.

Boiler replacement
Customer Service
AGW replaced our old combi boiler and moved a radiator in one of our bedrooms. Andy visited to quote and emailed the quote later the same day. Date for work was set quickly and all communication was was prompt. Andy’s team arrived on time on agreed day and worked diligently to get the job completed the same day. The team tidied up when they had finished and Andy reassured me to contact him if we had any issues in the future.

A first class service all round
Customer Service
Our Boiler finally gave out during recent cold weather on a January Sunday evening, on phoning AGW, our normal boiler service engineer first thing Monday, they arrived by 11.30am and managed to get the boiler operating again, but confirmed that the boiler was on its last legs. We had been informed about this likely situation during it’s annual service some three months previously. A full quotation for a new Worcester boiler was sent to us within two days, which was accepted as it was very competitively priced.The installation was carried out in one day, on a date that suited us, and also with nothing for us to clean or clear away. The New Boiler is a great improvement, and almost silent. AGW are extremely pleasant to deal and very efficient, we would not hesitate it recommending them.

A complex job done with professional skill.
Customer Service
Andy and Tim are very knowledgeable and experienced. We were having an urgent replacement of a 23 year old Potterton gas boiler by the latest Worcester-Bosch. We'd had an earlier quote by a well known local rival, but were not impressed by his method. Andy's quote was higher than his, but justified by his advice for a higher power model of the boiler, a replacement of the pump, etc. -- and why. Andy sticks to his quote and his thorough list of what he will do, whereas the other man expected us to sign a legal document with a long list of legal clauses, after a very vague list of what he was going to do. The whole complex job was started at 8am and was done by 4.30pm. Not cheap, but good value.
