The after sales service was outstanding. I rang with the problem and they offered good advice and provided a rapid fairly priced service. I would have no difficulty in recommending them and would certainly not go to any other plumber for a boiler problem or installation

Caring and reasonably priced Company.

The engineers came today to service my 20-year-old boiler. They were very thorough and professional. Showed the inside of the boiler, which was leaking, burnt, and rusty, and told me not to use it for health reasons. They booked an appointment to put in a new boiler. I agreed, and they are coming the next working day. Very happy with the outcome.

The company responded to my problem with my toilet cistern within 3 hours. The two plumbers came fully prepared with the correct parts for the repair following my email with a couple of photos. The job was completed within the hour. The new parts included a mechanical flush mechanism which is far superior to the part it replaced. Tanny was clearly good at his job and overcame the difficulties presented by a reluctant old cistern with confidence. I have turned to Basi gas on many occasions over the years and have always received first class service at a fair price.

We've been using Basi for our central heating since we moved in to our house. They installed new radiators and both our boilers over the years. Service is always good, communication is great and very reasonably priced too.

Basi came to quote the removal of my old Baxi solo heat only boiler still working but spares becoming scarce been in faithful pretty much trouble free service for over 25 years
They sent the quote to do the job with anew Baxi 600 heat only unit not the cheapest but felt they would be a better choice and I must again compliment the installation team on a excellent job done to a very high standard which you don’t see to often nowadays

Had new boiler fitted and could not be happier. Price was extremely competitive, engineer kept me informed during the fitting, gave a demonstration after completion of works. Would highly recommend to anybody needing a new boiler.
