Shop for Skylights By Size
Skylights are designed for uninhabited spaces, such as your attic, shed, stable or outbuilding. They will add daylight and fresh air into an otherwise stale environment, and, as they come with fitted flashing, they are a cheaper way to get the most out of a space.
What's the difference between roof windows and skylights?
Roof windows and skylights differ in that skylights don't meet build regulations and so are limited to use in uninhabited spaces, such as hallways, lofts and outbuildings. You can find more information on the Planning Portal.
Roof windows flood your loft conversion or extension with lots of daylight, fresh air and a clear view, adding a real impact to your home.
Range of choice
The leading brands offer a range of innovative roof window designs with a solution for every need. Whether your installation is low in the roof and you need head space (opt for a top hung frame) or is high up (opt for a remote controlled model), there is a budget friendly answer for your home improvement project.
Bargain hunters, gadget lovers, design
Are you a bargain hunter, a technophile or looking for the wow factor for your home? Our selection has a roof window for you. We can offer you a window with high quality components at a budget friendly price, the ability to control your windows and blinds from the comfort of your sofa or a stunning feature.
Skylights are a low cost way of adding daylight and ventilation to a loft space, garage or shed. They are strictly for uninhabited spaces.
Value for money
Whilst being the UK's cheapest skylight, the models we sell are definitely the best value for money. Their simple, effective and durable design ensure you receive all the benefits of natural light whilst protecting your space from the weather for years to come.
If you need roof access, as well as light in your uninhabited space, choose a model that allows easy access onto the roof to perform maintenance work or as an emergency escape.
