I installed a 1400 x 1200 Flat Rooflight for a client and can thoroughly and totally recommend TGS.
First the ordering process was clear and simple. Then, as it was the first time I had used this product and my determination to understand the fitting process and to ensure a robust and leak free product, I contacted their technical section who couldn’t have been more helpful. Result was a perfect installation that looks pleasingly simple, stylish and floods the very contemporary extension with light. Thanks guys - I’ll certainly recommend and use you again.

I've used flat roof lights from Toughened Glass Systems in three residential projects and they've not only enhanced the visual appeal , light distribution and ambiance of our living rooms, but they've been holding on very well over time. The value for money and service provided by them has always been on point so I'm happy to recommend them.
