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.

Excellent Job Done to Schedule and Budget
Customer Service
Good plumbers are like hens' teeth , but we found this one. An excellent job done to schedule and budget despite a number of problems arising as it was a complete upgrade of an existing bathroom. The quality of his workmanship was of the highest quality and the tiling was superb. It was all done within five days and we are very satisfied customers. From his first visit to estimate the job through to the successful conclusion of the job , his attitude, helpfulness, cleanliness and communication could not be faulted. We were very fortunate to find Celsius and would highly recommend David Osbourne to any potential clients. The only downside is that you might have to wait a couple of months for a place on his schedule - but believe me , it is well worth the wait .

Superb Firm
Customer Service
I cannot praise Celsius enough. On 15th November we reported that our boiler had failed. Upon inspection we were told that the fan had stuck but had been lubricated and all was well. However, we were warned that it might fail again but that the details of the fan had been noted. Today it failed again and I reported this at 0815. The engineer arrived at 0915 with a replacement part and by 1000 all was working well. As customers of Celsius for many years we have always found the service to be quick, superb and caring. The whole staff deserve credit for their dependability.

Many thanks for taking the time to leave a lovely review, we were very lucky on this occasion to be able to rearrange some jobs to accommodate for the breakdown and have the part in stock. We were happy we could get you back up and running as it was very cold that day. It has been a pleasure working for you over the years, Kind regards Claire @ Celsius
They serviced the boiler and two gas fires
They arrived on time on date agreed. This was the annual check of the gas boiler where checks were made visually on boiler and flue. I think they cleaned and adjusted certain parts. Both gas fires were stripped down, cleaned and checked. Adjustments were made to gas supply to ensure burner working properly. Both flues were checked for tightness and no leaks found. Both fires were rebuilt and tested on completion. Both fires are working well.

Thanks you Christelle for your lovely review, our engineer David is very experienced with underfloor heating and I am glad he managed to resolve the issue. Kind regards Claire @ Celsius
Superb work from Celcius
Customer Service
David gave a quote, indicated that he was busy with other projects but set a date on which he could do the work. He turned up exactly on that date, did the work very efficiently with his team, was caring to my old mum in her flat, communicated progress extremely well, solved problems that were hidden at time of quote, adjusted quote very reasonably, and left her with a spectacular new bathroom.
