-
Our pitched rooflight has made such a difference in reducing outside noise. It’s like our own quiet sanctuary now.
-
As a builder, I’ve installed quite a few skylights but the ones from KingsView are by far the easiest and most satisfying to fit. The customer support was super nice, always available to answer my technical queries.
-
In Manchester, our attic space was dark and unused. The 400 x 3000 pitched skylight we installed has completely transformed it. Highly recommend KINGSVIEW!
-
I was a bit hesitant at first but installing a pitched roof skylight in our tiled roof was the best decision. The skylight is not only functional but also adds an elegant touch to our home’s aesthetic.
-
I opted for a long 400×3000 mm skylight for our hallway. It brought light into a typically dark area. Installation was fast and secure and the visual impact is just what we hoped for.
-
Great customer service and a brilliant product. The roof window makes our loft look amazing!

Crystal-clear glass, modern frameless design, and easy installation—this pitched roof window is perfect!
