If anyone is ever looking for heating engineer/plumber...please call Celsius Plumbing & Heating in Troon. We have had major issues with 2 cold rooms. After various quotes from other companies ranging from £500 to £1900 to change 2 radiators I called in David's company Celsius. After spending an hour with us , he told us that all we needed was for the system to be balanced. In other words no new radiators needed. 24 hours after his first visit David returned and did just that. For the first time in 6 years we have heat in all our rooms, so much so that we have turned down our thermostat. Many thanks David, we will be back in touch soon to chat about our new bathroom

HIVE Heating Control Installed
Customer Service
The team at Celsius were a pleasure to deal with when setting up this installation appointment and while the job was being done. They arrived when they said they would and were friendly and helpful throughout. They even went over and above and saw to a leaky pipe I had asked for some advice on, while they were there. I have now confidently signed up to their home care plan to look after my heating and plumbing going forward. Highly recommend.

15 year old combi broke down and uneconomical to repair New combi fitted within 24 hours . Neat and tidy . The previous one had replaced the original which heated water with immersion heater but pipe work unchanged resulting in twenty metres of pipe from combi to kitchen tap . David changed pipework resulting in one metre run . Another 5 star performance !

New Boiler Installation
Customer Service
Celsius provided quotes and recommendations after our boiler became “unfixable” during the cold snap mid January. 48hrs later the boiler was installed and working. Excellent service by local tradesmen, would highly recommend. Both Davie and Jim were a pleasure to deal with and ensured we were familiar with the mechanisms of the new boiler. Many thanks

Boiler repair
Customer Service
From the first phone call this service was professional, knowledgeable and high quality. The engineer arrived exactly when expected. The repair was carried out quickly and afterwards the engineer spent time explaining what he had done and things to look out for in the future. Receiving the invoice by email is excellent and with a week to pay really takes the pressure off. Love that I can also pay online. Seamless service from start to finish.

Outstanding Trusted Trader
Customer Service
I have been a customer of Celsius, Troon, for a number of years now and cannot recommend them highly enough. From routine boiler servicing and minor problems to potential catastrophes, both David and Sandy have gone out of their way (and outwith their working hours) to give expert support and skilled workmanship to the very highest standard. It is really reassuring to know that Celsius are there and that they really care for their customers!

New bathroom
Customer Service
Our bathroom is fabulous, David created a room fit for my advancing years it was a complete renewal not a makeover with new from ground up and a change of door position needed. The floor was replaced room tanked for wet room tiling fantastic floor tiling flows and gathers at the drain so the water drains away well. It is the second bathroom David has renewed for us and both of them are excellent.I highly recommend him to any one who wants a job doing extremely well and correctly

Superb service
Customer Service
Celsius Plumbing have done several jobs for me in the past, sometimes sorting out problems which other “tradesmen” had caused, so I had no hesitation in asking David to do my very small kitchen. Claire in the office did all the administration very efficiently, always communicating with me when needed. The job was started on the due date and time by David. It was a particularly challenging task as only one person could work in the small space available. However, as usual, David looked for solutions rather than problems and the result is a kitchen which is both functional and beautifully fitted. It’s now a pleasure to work in it. David is an expert craftsman who is reliable, trustworthy, resourceful and fair. Need I say more?

Exemplary service
Customer Service
The gas boiler broke down at 4 pm on a Friday with a forecast of minus degree temperatures. Despite being told the cold was a health risk for my 78 year old wife , the company who have serviced the boiler every year for the previous seven years declined to come out for four days. Contacted Celsius and David turned up within an hour, found two faults, one pre-existing, completed the repairs and stayed for a time to ensure no further problem. An additional payment was offered for out of hours call but was declined. Future annual services will be done by David

Customer Service
After many years, many failed attempts and many thousands of pounds spent on building a wet room. What we actually had was a badly built bathroom completely unsuitable/unusable for a blind disabled person. Using several different companies we had failed to find any that could satisfactorily do the work. David Osborne/ Celsius was suggested and was highly recommend both online and by word of mouth. His quote was slightly higher than some and less than others. We cannot thank or recommend him highly enough. He arrived on agreed start date, turned up every day, worked all day. Completed wet room ahead of schedule. Advised us constantly of job progress and details of work being carried out. Consulted with us on specific details like choice of extractor fan etc. He left no mess removed all debris and was very respectful of our home. He left us with a beautiful, perfectly working wet room that has exceeded all our expectations. He fixed a wet room that no one else could sort. Given the amount of work done and the final result, the end cost was absolutely worth every penny. Finally, we have a perfect wet room. Thank you so much David, Celsius & team
