Detailed reviews
John's style of working was great, he did the job we asked him to do but more importantly advised us that parts of our ststem were not working properly and advised on how to fix it. He communicated well by text so we knew when he was travelling to our house and gave us confidence that the problems were fixed and our system should last a lot longer.

I can always trust John to do an excellent job
Would not hesitate to recommend Thermostatix for all plumbing work and installations. John is always reliable and his work is of the highest quality. He services our boiler every year and tends to any repair work as necessary. He also installed our bathroom a few years ago, together with Tom, and we have always been extremely happy with it. Can always trust Thermostatix 100% to get the job done and with 100% quality.
Good people to deal with.
I am very happy that we used Thermostatix. Initial contact was with John and he put Tom in touch to carry out the works. Very good communication throughout and the work was carried out with great quality and care. This was a great recommendation and they are definitely a company we would happily recommend. Top quality work!
I am always impressed by John's (and Tom's) work and his kind and courteous nature. He worked on a difficult project for my elderly father to ensure his safety was a priority. Rates are very competitive too. I will continue to recommend Thermostatix to my friends and family. Highly recommend the annual boiler service too over the expensive British Gas contract I had
As always excellent service
I have been using John for the past 2 years, and always found his work, reliability and character absolutely first class, I would recommend him and his company without hesitation !. I called John on the Friday and he came round on the Monday and replaced a faulty CH Synchron motor. I always use him for my boiler annual service and any other work needing a plumber.
Tom was easy to deal with from providing a quote to completing the work. He removed our old boiler and hot water cylinder and replaced it with a combi boiler. He was always conscious to minimise the disruption caused by this type of work and completed the work in the timeframe agreed. A really great service!
John was able to identify and clear a blockage in the kitchen drain pipe, and, as a result, the sink waste, washing machine and dishwasher will all work much more efficiently. Thanks so much John; really appreciated!
Always honest and reliable. Helps me out at short notice when possible. Highly recommended.
I have used Thermostatix several times and have no hesitation recommending their service to friends and family. I'm so impressed with the care, courtesy and professionalism they always show. From installing a new bathroom to servicing the boiler, I have so much confidence in them I would never go anywhere else. Thank you John and Tom
Top service and communication. Highly recommend as always.
Have used Thrmostatix before and no reason to go anywhere else. Thank you for getting us over a bath leak. Rectified & tested same day.
I originally found Thermostatix on Trustatrader many years ago and use them for all work from servicing of my boiler through to plumbing and other heating work. For this piece of work they removed a radiator and fitted a new one and, as usual, the work is of a very high standard and done quickly. They recently replaced my boiler to the same high standard of work with a very competitive price. I cannot recommend them highly enough and i do not use anyone else.
Outstanding work and service, John was onsite within 10 minutes of the initial call! He quickly diagnosed the faults, clearly communicating and explaining the faults and options for repair . He located the specialist parts required, collected them, returned and carried out the repairs efficiently, working very clean and tidily. John explained all steps along the way, was very polite and genuinely concerned about making the works as cost efficient as possible. What a great find, so glad I choose Thermostatix - Really nice bloke to boot, can’t fault any aspect - quality job!
Excellent as usual.
I was very happy indeed with the service provided by John from Thermostatix. I can’t fault him at all as he was polite, punctual, respectful, explained what he was doing and was tenacious about solving the problem. I would absolutely recommend him to others and shall use him again myself in the future.
