We have used this company for the last three years ,and have always been happy with the service provided.The engineer arrives on time and completes the boiler service carefully and efficiently,checking everything is working properly before he leaves. He has a very nice manner and is polite and friendly. They also send a reminder when the annual service is due,which means you never have to worry about forgetting to have it done.

Fantastic service

I have used C1 Boilers for a number of jobs since moving into our home. For boiler servicing, radiator issues, fitting a thermostat and supply and fitting of a new shower. The service is always fantastic, from booking a job where I received a fast quote and flexibility on when the job can be completed to the actual day of work, when I received a phone call to let me know they are on route. Work has always been completed to an excellent level and very fairly priced. Would not use anyone else and highly recommend for any heating or plumbing work.

We have used C1 Boilers a few times and they are always polite, prompt, professional and friendly. They turn on up on time - and there is a great automated system that let's me know when they are nearby. Connor is always really helpful, and efficient. Would highly recommend.

From the minute I phoned the service was speedy and efficient. The only company who took notice of the emergency we were in and fitted us in. Also no pushing extra products or services . Thank you all.

Leaking valve

We contacted Connor as we had a leak from our boiler and he came the next day and found the problem and explained what it was and that he couldn’t fix it as it was still under warranty. He explained what we needed to do in order to get sorted. Connor was very thorough and checked everything else was in order and we will definitely use his service again

Connor was very polite, efficient and considerate by ensuring he wore overshoes etc whilst in my home. The service was completed thoroughly, as per last year, better than any previous company I have used for same service. Radiators were all checked as well. Very satisfied with C1 Gas and heating services.
