Fanastic customer service! We moved into a new building which has Thermosphere radiators installed and has an issue with one of them. The Thermosphere team (Darby Bell) was easy to contact, and expediently arranged for a resolution. It was good to have people to contact and not go through automated bots and bureaucratic processes to get real help.

Ellie was very helpful and managed to obtain the part required for my defunct TH132. Delivery was next day and I now have once again a bathroom with a warm floor. Excellent service. Thank you.

The advise I was given about the Thermosphere underfloor heating was excellent. I have had very helpful and continuous support throughout having the product installed.

Installing underfloor heating and I can’t speak highly enough of Darby Bell, who has assisted me throughout the process in such a knowledgeable and helpful manner.
Fantastic customer service, can’t wait for the gear to install. Thank you once again.

From the first point of contact ( enquiry about the length of flex on their heated towel rails) through the technical information & sales which shaped the decision to purchase their HTR as opposed to a myriad of cheaper competitiors was superb, and always quick & curteous. Rate this company 5 stars for service & product

Exemplary customer service from Ellie Lisbon. She was polite, friendly and extremely knowledgeable. Two replacement thermostat control panels sent out under warranty the same day, and received within 24 hours-brilliant!!

If you buy a ThermoSphere Dual control and it is commissioned incorrectly, have no fear as Ellie Lisbon is at the end of the phone waiting to help resolve any issues. She is exceptional! She really understands the product. Her professionalism is a credit to the after sales service offered by ThermoSphere.

I just wanted to leave a review for Ellie as she was exceptional on the phone yesterday! She helped me re programme my thermostat and made is so easy. Ellie really knows the product and the app inside out she has even booked in a call back for October to set my winter schedule. I’m amazed with the professionalism from this company.

I have dealt mainly with Ellie . I never write reviews but I am so impressed with her she desrves one! She is super helpful, friendly and has the HUGEST amount of patience which is very rare when dealing with customer services sometimes!! She deals with things very calmly and has a good sense of humour to boot !. I am super impressed with this company , their products are great and the after care 100 %. Thanks Thermoshere

At the beginning of 2022 we moved into a newly refurbished house fitted with thermoSphere underfloor heating and Thermostats. We have been really pleased with the air thermoSphere products but in the week before Christmas one of the LED displays in a Thermostat developed a fault. thermoSphere customer services were extremely helpful and the next day a replacement thermostat arrived on my doorstep. I have nothing but praise for the efficiency and helpfulness of this company and their customer services department.

Our builder recommended Thermosphere UFH products for our new kitchen extension build. We bought it from a local tile shop and were very impressed with the performance and product. Not only does the floor heat up really well, but also heats the room. And the thermostats look great.

Our company installed hundreds of electrical underfloor heatings including the Dual Touch Coontroller and heated towel rails by Thermosphere on a high end residental project in central London. The whole supply chain worked very well. Thermosphere support over the construction period was excellent. We had absolutely no claims and can recommend Thermosphere.

Reply from ThermoSphere
Ellie was exceptional, she was knowledgeable and for the first time in a long time I really felt as though I was talking to an expert, ultimately her technical advice and support regrading towel bars and glass panel heaters led to us making a decision to move away from traditional plumbed heating to electric.

We have used Thermosphere a few times now and Ruben has been absolutely brilliant. It's never too much trouble to amend quotes and answer our queries. The product itself it also the best we have used and makes UFH installations so much easier. It is a pleasure to work with them and would highly recommend.
