Very pleased
Customer Service
I initially contacted 1st gas for a service, after reading good reviews. However, whilst I was away my daughter I formed me that there was a problem and I changed it to a maintenance call. This was all done efficiently and timely, it was bad news the boiler would be far to expensive to repair and a new one was recommended. After, a few frantic calls home from Spain, an appointment was made and a new boiler installed which we are very happy with. I did all the arrangements via email and a chat over the phone with the engineer. There was no fuss that I wasn’t there in person and made the whole process as stress free as possible a couple of weeks before Xmas. Thank you

Efficient and Friendly
Customer Service
Time for my annual boiler service and it's impossible to forget. The team at 1st Gas send out reminders with a link to book the service in on a day and timeframe that suits me. They turned up on time and completed the work while I carried on with my day and everything was left working perfectly with no mess. Happy to recommend 1st Gas for anything heating and water related around the home.

Fantastic Customer Service
Customer Service
I cannot recommend this company highly enough. I was desperate for help when my boiler breakdown provider had a 3 week waiting time for emergencies. 1st Gas came when they said they would, told me what was required and how much it would cost. The work was carried out the following day with all Covid-19 precautions taken. It was a lengthy job but the engineer kept me appraised of process, showing me where and what the problem was. Needless to say 1st Gas will be getting my business from now on and my current provider a complaint!
