Extension Skylights

An extension skylight makes the new space feel like it was always meant to be there. At Rooflights & Skylights UK, we design our extension skylights to bring natural light into rooms that might otherwise feel closed off or disconnected. Light pours in from above, tying the extension to the rest of your home and making it feel open, bright and purposeful from day one. Built to fit seamlessly into new builds, they're tough enough to last and priced so you don't have to compromise on quality to stay on budget.

Add Light Where It Matters Most

If your extension includes a kitchen or dining space, place a skylight right above the island or table. It brings focused light exactly where you prepare food, cook, or gather as a family. Wall space can be tight in home extensions, so when windows aren’t an option, a rooflight gives you the daylight you need without taking up valuable wall space for the kitchen cupboard layout, for example. Our home extension skylights have a clean design, are practical and made to fit seamlessly.

Frequently Asked Questions

Our UK crafted skylights are weather tested to handle the harsh UK weather. With proper flashing and seals you can stay worry free from leakages.

Absolutely. Skylights undergo rigorous testing, featuring toughened or laminated glass that resists impact, extreme weather and even burglary, depending on the model.

Extension rooflights turn gloomy corners into sunny, wide-open zones that practically double in size. You’ll cut down those big power bills since no lights are needed during daylight.

Most roofs can support skylights whether flat, pitched, or vaulted. The key is matching the right model (like curb-mounted or self-flashing) to your roof type.

Nope. Our high quality vented skylights come with insect screens and weather-tight seals to keep drafts and critters out, while bringing fresh air in.
