Complete bathroom refurbishment
Customer Service
When Jason visited to give quote on works he made me feel at ease, answering all my concerns which led me to choose A1 for our bathroom refurbishment. Carl and Lee in the office were great and dealt with any concerns and questions we had quickly. Joe was absolutely fantastic, was always punctual, tidy and really hard working and took such pride in his work. My bathroom is amazing and I would highly recommend them to anybody, I can’t thank them enough. Absolutely brilliant!!!

New bathrooms after removal of old units/tiles/ceiling
Customer Service
Pleasure to meet Carl, Jason & Steve. Their admirable attitude & desire to please was praiseworthy. Excellent design & first rate workmanship. All work was finished to an exceptional standard. They went above & beyond in all aspects of the work completed. Work was completed ahead of schedule & the cost was exactly as quoted. High quality work on all parts of the installation. They are thoroughly recommended. I can't praise them enough. I would use them again & again & again...

Really happy with the job
Customer Service
A1Gas did a great job installing a new boiler and radiators, and then revamping two bathrooms. Polite service, always on time, tidy. My house is old and has a few quirks so it was good to be with a company with experienced staff who could handle the boiler replacement and associated issues. Happy to recommend.

Excellent work to rip out and replace a shower and cubicle
Customer Service
Absolutely fantastic service from A1, from start to finish. Jason was polite and friendly at quotation, Carl was very helpful over the phone with booking and invoices and Steve (who did the work) was friendly, polite, hard working and completed the job to an excellent standard. I am so pleased that I used these guys and would recommend them without hesitation.

Excellent service, skilled engineer, fair price.
Customer Service
A1 Gas repaired my gas central heating boiler after it broke down due to a broken fan. The engineer was extremely knowledgeable and I felt very confident in his abilities. The part was replaced and the boiler repaired quickly and efficiently. The engineer was polite, tidy and very careful in his work. The price charged was very fair. I will definitely use A1 Gas again and would not hesitate to recommend.

I now have a wetroom as opposed to a paddling pool
Customer Service
Recently had a wet-room installed, despite raising concerns about the installation (falls in tiles outside the shower area, and under floor heating in shower tray) my concerns were ignored. The shower didn't drain and the lack of falls outside the shower tray meant that I had a 5mm pool of water under the toiler after every shower. Contacted A1 who put my mind at rest, assured me I wasn't alone, that they see this every day, and that they could help. The site survey filled me with confidence, and the quotation was appropriate for the level of work involved. The job was completed on time and on budget. Great care was taken during the works to protect the chrome fittings that they installed, and also the existing ones. The guys cleaned up after themselves every day and left the house usable minimising disruption. The finish was of a very high standard and most importantly the wet-room now works. They did exactly what they said they would do, for the price they said they would do it for. What more could you ask.

Bathroom renovation
A1 Gas Ltd did a total renovation of my bathroom, including taking out a wall, re-plastering, fixing damaged flooring, fitting a new bathroom door and installing my new fixtures and fittings to a very high standard. Everyone at A1 Gas Ltd was polite, helpful and professional at all times and the job was done on time and to an agreed quote. Very happy!
