Boiler installation with 26 meters of 28mm gas run pipework

Anthony & Kian, are very polite and friendly; they hard workers despite various curve balls my property through at them; they took it all in their stride. I had a small bathroom leak nothing to do with them, but they capped it as part of the job to give the customer an above and beyond experience. I would recommend Swansea gas & oil.

New gas supply pipes/refit flue

Anthony was a pleasure to work with, polite and honest about the work that needed doing. I called for a boiler service but Anthony informed me that our gas pipes were very old and needed renewing to comply with regulations. Our flue was also incorrectly fitted by the previous owners and this was rectified. I also mentioned that the mechanical timer on our 10+ year old boiler was on the blink and he offered to fit a modern digital thermostat for a reasonable price. Work was completed within a day and with minimal mess. Happy customer :)

Boiler Replacement

I initially called Anthony as my boiler had started leaking. He was quick to come to check out the boiler and made a point of showing me where the issue was so that I could see for myself. He ordered the part that needed to be replaced and was back with me as soon as he had the part. Sadly for me, another part had given up and a second leak could clearly be seen. As it was an old boiler I asked Anthony to replace it. He advised the cost and timelines up front and work began immediately. The job was completed to a great standard, clean and tidy, and super fast! Highly recommend these guys!!

Gas combi boiler installed

Arrived at the time promised and carried out the work efficiently. They were polite and kept me updated with their work. Explained and demonstrated everything I needed to know. I would not hesitate in recommending them to friends and family.

New boiler

Our boiler unexpectedly went so we had no hot water or heating. After various quotes, I felt Anthony was a genuine guy who was competitive against others on price. Pleased to say I was right. As this was an urgent job, Kian made a start the following morning whilst Anthony finished on an existing job. Both Anthony and Kian were excellent and hardworking. Communication and quality of work was excellent. I will only be using Swansea and Oil going forward and have already recommended Anthony and Kian.

Boiler fitting

Professional and courteous throughout, Anthony and Cian worked fast to get a new boiler fitted within 24hrs of me posting on check a trade. Needless to say ,I won't be needing check a trade for plumber any time soon as I'll be using Swansea gas and oil and would feel confident in recommending them to friends and family. Many thanks

Installation of new oil boiler and radiators

Anthony and his team were excellent. The oil boiler and radiators were beyond economical repair. Anthony provided provided all the necessary information so we could make an informed decision to install a new oil boiler and 12 radiators. Swansea Gas and Oil completed the project in three working days. Anthony was polite, helpful and punctual. If there were difficulties he kept us in the loop. I found Anthony and his colleague to be hardworking, conscientious and enthusiastic in their work ethic. Cost was within budget. I have no hesitation in recommending Swansea Gas And Oil to others.
