Excellent service from point of contact to completion of work
Customer Service
First contacted Celsius when we moved house and required gas safe inspection and an estimate for a new boiler. Unlike other firms in south Ayrshire, a timely estimate was provided and when accepted a timescale was agreed following discussion on options and Davey turned up to complete the work which he did to a high standard. He discovered a small but long standing leak which required him to replace floor boards. We were so impressed with his professionalism, we have gone on to commission him to create a utility room, new bathroom and new kitchen. Davey has created a reliable team around him from administration, to other trades and so we have not had the added stress of having to arrange electricians, plasterer, roofer, or arrange skips. He pays attention to detail and resolves any issues in a calm manner. I would unreservedly recommend Celsius.

Terrific company and service
Customer Service
From the initial investigation of a non working boiler to a replacement new boiler I cannot fault David and the company at all. Prices and quotes were more than acceptable every time. They were able to find time in busy days, very late on one occasion, to look at and trace faults in the old boiler when we had no heating or hot water and they did this on more than one occasion. We then decided to opt for a full replacement given the age of the original boiler and were offered good quotes for different boilers the day of our decision. They did the work within 24Hrs of the quote being received by us!! Work area was clean and tidy when they were done. Phone call always answered or returned and they are friendly and helpful every single time. Cannot recommend enough.
