Skylight windows do not require planning permission in most cases. In general, skylight windows are considered to be a permitted development, which means that they don't require planning permission as long as they comply with certain specific conditions. These conditions usually relate to the size and location of the window, and how it might affect the appearance of your home or the privacy of your neighbours. If you're not sure whether or not your skylight window will comply with these conditions, it's best to speak to your local council or planning department for advice.
No, planning permission is not required for skylight windows. Skylight windows are a great way to let in natural light and add some extra ventilation to your home. They can also be a nice way to add some extra personality to your property. If you're interested in installing a skylight window in your home, be sure to consult with a contractor to see what type of window would best suit your needs and architecture. Keep in mind that while skylight windows are a great addition, they may not be the best solution for every home.
