Now satisfied

The Engineer must have run out of black sheathing and therefore ended up using white for part of the installation. He did not tell me, whilst I could have provided him with some if he had. He also forgot to carry out a modification to the route that had been discussed for the pipework.
Credit to this company who returned twice to address issues that I had with this work. Further credit because, having paid immediately on completion of the work, I did not have the leverage, that an unpaid bill might have given me.

Extortionate quotation

I needed to get valves fitted to some radiators and as Mains Gas had very good reviews on both Google Maps and Trustpilot, I asked for a price. I couldn't believe it when the quotation sent was £900! Suffice to say I went elsewhere and had the job done for a fraction of the price.
I didn't request a powerflush and I made it clear that we already had the radiator valves and they just needed fitting.

Hi Paul, I’m so sorry that you felt the need to write a bad review. We did try contacting you on a couple of occasions to no avail, to let you know that the power flush had been missed off the quotation. I have listened back to the telephone conversation you had with the lady in the office. The quotation was an estimated cost for a full power flush of your central heating, including adding inhibitor and cleanser and the replacement of thermostatic radiator valves, we hadn’t attended the property to give you a fixed price and this was a quotation completed over the phone. The quotation also included vat. We have over 54 amazing reviews on here from very happy customers, it’s just a shame you felt the need to share this instead of talking to us. If you would like to call the office to discuss in further detail, we are open 6 days a week. We wish you all the very best in the future. Kindest regards Mains Gas

Excellent and knowledgeable engineer (Nathan)

. I have used Mains Gas several times before and have found them to be excellent. Customer service is fantastic, polite helpful staff who go over and above to ensure you receive an excellent customer service with courtesy calls.

On this occasion, my central heating had broken down. The engineer who attended was called Nathan. I can’t speak highly enough of him. He identified the problem immediately, There was a tap that had been leaking in the bathroom for some considerable duration. The system was therefore producing hot water and not central heating. Once the leaking tap had been stopped, the central heating was back up and running. I was very impressed with how quickly Nathan identified the problem and how quickly he fixed it. In addition, he was a very polite and courteous man who arrived promptly in the timescale provided. He is a credit to the company. It’s this type of service that makes you recommend them to others and use them again

I rate my experience of Mains Gas as excellent. Their customer service is fantastic and their engineers are skilled and knowledgeable.

Before we ordered the tank and boiler…

Before we ordered the tank and boiler from Mains Gas, Sam and Cath in the office were extremely helpful and answered all of our queries in an efficient and professional manner however trivial they may have been. When it came to installation, Tristan, Cian and Lee were incredibly polite, courteous, punctual and very, very hardworking and overcame all setbacks professionally and with good grace. The boys were a pleasure to have around and we would recommend them to anyone.

Quick and friendly service

Our boiler wouldn't work after we'd been away for a couple of nights. We called in to see them, they recognised us when we walked into the shop and said they'd look at it within a couple of hours. They remembered we'd booked with them to have a new boiler in July, so we didn't want to spend too much on the repair.

The engineer found that the fan was seized and he freed it, oiled it and said it should be OK until the new boiler is fitted, as we couldn't be without heating and hot water for 2½ months. He explained everything to us very clearly and the service provided was excellent.

How refreshing to have a professional…

How refreshing to have a professional gas fitting service in Brecon! You phone, a pleasant person answers without undue delay, you describe the problem and, either immediately or after a few hours, a date and time for an engineers visit is arranged. Either the appointment is kept or the office contacts you well in advance to arrange another time. Our LPG boiler problem was identifierd and rectified without a hitch. Billing is prompt and itemised. Why can’t more local businesses be run as efficiently? We have subsequently engaged Mains Gas to replace a radiator in our house.
