A Guide to Purchasing Skylight Windows

A skylight window is a great addition to any home; not only can it brighten up a dreary looking room but it can also make the room feel bigger, airier and often, more stylish. Additionally, homeowners with a skylight window directly above their bed can enjoy the novel activity of stargazing on clear evenings, while waking up to glorious sun rises in the morning (if they so wish). However, if you’re looking to install a skylight window in your home, there are several considerations you should make before purchasing one of these popular roof windows: 

Planning Permission

The first of your considerations should be whether your skylight window will require planning permission. If you are installing a skylight window as part of a pre-agreed extension or simply substituting an old skylight for a new one, you shouldn’t need planning permission. However, if you are installing a brand-new skylight window, while it is still unlikely it will be needed, we recommend checking with the authorities whether planning permission is required. This is because, in line with current building regulations, certain buildings must only incorporate a certain amount of glass; consequently, by installing an additional skylight, you may be exceeding this amount.  


Next to consider is where you are going to place your skylight window. While you may want to get as much natural light as possible into your home, the risk of overexposure to UV rays must also be considered when positioning your skylight window. Direct sunlight is more common on south or west facing windows while those facing north and east tend to get less exposure, sometimes none at all! Consequently, if you’re looking to install a skylight window on either the south or west sides of your home, you may want to invest in blackout roof window blinds to ensure your room remains at a comfortable temperature and that you are protected from potentially harmful UV rays.


Skylight windows can provide excellent ventilation to a room, especially if they can be opened to their full capacity. If you’re planning on having a functioning skylight window, make sure that you position it where it can be opened and closed without being blocked by other objects, e.g. a drain pipe, neighbouring roof, trees etc. This will allow you to ventilate your room with a burst of fresh air whenever you feel necessary by opening your skylight window.  


You should also consider the size of your skylight window depending on firstly, how much light you’d like to enter the room and secondly, whether you will be using the window for ventilation purposes. A bigger window will enable an increased amount of light and air to stream into the room, while a smaller skylight will provide a narrower beam and slightly less air flow. However, as well as light and ventilation, if you’d like to capture a particular view from your skylight window, its size may ultimately be determined by the level of slope on your roof. For example, if your roof has a more angled slope, a taller window will be required to achieve a better view. If you are unsure of what size your skylight window should be, your chosen manufacturer should be able to help with recommendations.


Installing a skylight window may sound reasonably easy as effectively all you are doing is taking out an old window and replacing it with a new one or cutting out a section of your roof and filling it with a skylight. However, installing a skylight window is a far more complicated process than this that requires both focus and precision; not only do structural considerations need to be taken into account but the measurements need to be exact to ensure the skylight remains watertight once installed. As such, we recommend opting for a professional installation rather than attempting it yourself (unless you’re a specialist window fitter!).
