Great advice on what sizes were required when contacted over the phone, after extensive research I decided to place my order.
The order was received within 2 days and my builder managed to fit it without any issues, the product itself is fantastic quality, the rooflight is a very nice design, and looks great from below with plenty of light. It has definitely transformed our kitchen extension.. Looks great!
