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!
