Fast initial diagnosis of problem. Once identified quick appointment made for replacement of hot water cylinder. On completion the engineer found a small leak due to faulty tank. Tank replaced next day with no fuss on their part. The fitter was polite hardworking and only left when completely happy that the job was done to our satisfaction. Highly recommend, price very competitive.

I was surprised and grateful for a prompt and efficient installation of a Bosch combi boiler. From advice on resiting the boiler from garage to kitchen, to a neat installation. I am so pleased with their prompt response, the fact that I can always reach them by phone, and the prospect of lower bills after all their excellent advice. This company is highly recommended by me.

TES reinstalled our heating (LPG) and hot water system following a rebuild of our kitchen over three years ago. We were impressed with the overall technical advice initially given for the design of our new system, and the installation was excellent. Since then TES have done our annual boiler and lounge fire servicing and the engineers seem very proficient.
