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

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

Customer Service
Claire and David are a marvellous team. David was able to pop by and look at mum's heating system, quickly diagnose the problem, get it working on a short-term basis and advise us on what was required next. His advice was clear, giving us a number of options and explaining what was needed. He does not put you under any pressure to quickly choose an option and gives you time to consider budget, timescale etc. Claire was able to order the part and advise us of the price in order that we could decide if we wanted/were able to go ahead or not. On coming to fit the new part David advised when he would come and arrived on time. He worked in his usual professional manner ensuring everything was done safely and to a very high standard. The result was that on the two coldest nights of the year, whilst mum was in hospital, mum's house was warm and even more importantly when she subsequently left hospital she came home to a warm house with a viable heating system. I cannot praise David and Claire enough for the service they provide. Everything is done with care, professionalism, consideration for the customer and excellent communication. David has an enthusiasm for his work and takes a pride in what he does. Although this was a relatively small job we have also used this business for a larger full bathroom refit and they were again excellent. I would have no hesitation in recommending them and indeed will use them again in the future if the need arises.

Celcius were contracted to carry out the installation of a water heater, change the location of washing machine and sink feeds and upgrade ancillaries. After receiving a quote, the project was completed on the agreed date which tied in with other trades. I was impressed with the professional, friendly service and positive attitude from the whole team at Celcius and I would highly recommend using this company, they are a pleasure to deal with.

Shower Screen Repair
Customer Service
I had ordered a new shower screen and David arrived on time with a pleasant manner. He advised that the screen had been fitted well and he could repair the leak without having to install a new one. I was delighted and said if that would save money go ahead and repair it. He took bits off and cleaned them well and when fitted back no leaks and a much cleaner shower. I had paid a deposit and when invoice came in I was owed money back. I feel this demonstrates a very honest and professional ethos within the business. Whenever I have had to call his clerical team have very helpful and pleasant.

Having used Celsius for previous work, called them again to refit main bathroom from initial designing to installation. As per previous experience found David and his team to be very knowledgeable and professional in all aspects of their work. Always professional, reliable and on time, wouldn't use anyone else. Great job.
