Customer's reviews

I can't recommend Thermotec enough for their honesty and expertise. Our old boiler failed, and Stuart gave us a detailed breakdown of the options. He actually offered to replace the heat exchanger to get it running again, but after discussing the costs and the long-term benefits, we decided a full boiler installation was the smarter investment for our home. He made the whole boiler replacement in Wokingham look easy. We now have a high-efficiency system with a full manufacturer warranty and much lower energy bills. If you want a heating engineer in RG40 who gives you honest facts rather than just a sales pitch, book Thermotec. The online booking system and fixed-price quote made the whole process stress-free ~ Macey F
We received several quotes for our hot water upgrade, but after seeing so many positive reviews, we decided to go with Thermotec—and it turned out to be an excellent choice. Stuart carried out a first-class unvented cylinder installation, replacing our old and inefficient gravity-fed system. Now we can enjoy mains-pressure hot water across all three bathrooms simultaneously, which has made a huge difference to our mornings. Although the job was quite complex and required extensive new pipework, Stuart’s skill as a G3-qualified engineer made everything run smoothly. He is, without question, the best heating engineer in Wokingham. If you’re looking for a true professional who delivers on their promises, he comes highly recommended. ~ Kate H
I have been having problems with my Vaillant boiler for a little while. I had Emergency cover through my home insurance through Allianz who over the course of a week sent two engineers who amazingly deemed the boiler beyond economical repair. I arranged for Stuart to have a look and he was able to get the boiler going quickly with adjustments, unfortunately it failed again and Stuart recommended a replacement of the gas valve. On removal the old valve seemed to be contaminated with shale probably picked up when our gas main was replaced recently. Stuart was prompt courteous and knowledgeable and I would thoroughly recommend to sort your gas appliances. ~ Richard H
