Sizes and prices
Standard sizes run from 300 x 300 mm up to 1500 x 3000 mm, with square and long rectangular formats in between. Each size has its own product page with the price shown, so you can order online. If your opening doesn’t match a standard size, send us your dimensions for a quote.
Measuring for a flat roof skylight
Each unit has a 100 mm step on every side, so its external size is 200 mm larger overall than the listed size. Check the overall external size against your upstand or kerb before you order, and ask us if you are unsure which size you need. Our guide Flat Roof Skylights: Sizes, Prices & What to Know Before You Buy covers this in more detail.

Do you fit skylights?
No, we are supply-only. Your builder or roofer fits the skylight, and we can recommend local installers if you need one.
