Our original boiler was working fine just very expensively so we rang round. The quotes varied by about £2000, BG being the most expensive. We found it difficult to get a response from local firms. I’m glad we got the other quotes though. Ryan from Phoenix was the last we saw His option was the least intrusive and almost the cheapest. It came with a 10 year guarantee (provided you keep it serviced) and a free first service. I didn’t expect Matt, the fitter to arrive at 08:00 on the appointed day, but there he cheerily was and I pretended we were ready for him. We had prepared by drawing off enough water for us to survive the day and were ready for the electricity to be off for an extended period but this was unnecessary. Neither supply was significantly interrupted at all. It was a synchronised display, electrician, bricklayer and various others ensured that the job was done and dusted by 16:30. There were problems but they dealt with them with a resigned good humour. And it works!. I had to ask for e mail advice as two of the radiators were not heating up, but that was quickly sorted. We are now nearly 2 years after the installation with the second service coming up. We have nearly forgotten about the boiler in the Utility room. It’s quiet, works and takes up a lot less space. If nothing goes amiss it will have paid for itself in 10 years. Everyone we have dealt with at the firm has been friendly and efficient, so definitely 5 stars and a large thankyou.
