Do you need planning permission for a flat roof window?

In most cases, installing a flat roof window does not require planning permission, as it falls under permitted development rights. However, this may vary.


Can you fit Velux windows yourself?

Yes, Velux windows are designed for easy installation, and many DIY enthusiasts choose to fit them themselves.
