Do I need approval to fit replacement windows?


Yes. Building Regulations apply to replacement windows but not to the replacement of broken glass only. You should check with your installer to ensure that he is registered with FENSAOpens in a new window. If so then the installer, can self certify compliance with the regulations.

If you propose to do the works yourself or if your installer is not registered, then you or he must make an application for replacement windows.
