Yes, if you are replacing the whole of the fixed frame and opening parts. If the work is to your home and you employ either a FENSA, Certass or BSI registered installer, you will not need to involve Building Control. If the installer is not registered under one of the above schemes you will need to submit an application. A Customer Guide is available on our Customer Guides web page.
No, if the work amounts to no more than, for example, replacing broken glass, replacing a rotten sash (opening parts) in the window frame, or some rotten sections of the main frame members.
