Small change outside – big change inside
According to the Energy Saving Trust, around 20% of the heat lost from an average home occurs through the windows. To reduce this, you can easily update old windows with options from Thermotech.
Recent Building Regulations state that all new window installations should meet at least a C rating on the Window Energy Ratings (WER) system. Luckily, Thermotech are partnered with the best in the glazing industry to allow all of our replacement windows to be A-graded, resulting in a reduced loss of heat and those all-important holiday savings!

February 2, 2020Wonderful company from start to finish! I purchased a new door a few months ago, the quality and the fitting is outstanding. Having an old stone wall surrounding the fitting was not an easy job, however the result is to perfection. Being a family run business they take customer service to heart. I can not fault this company and would highly recommend it.

February 2, 2020This small family company was excellent from start to finish. Then the after sales service was so efficient, Karl was at the end of the phone if the need arose. I would definitely recommend this company and would use them again.
