In most cases, you will NOT need planning permission for installation of windows but will require a FENSA Certificate.

As from 1st April 2002 all windows and doors (doors being 50% glazed or more) installed after this date will require a FENSA Certificate.  On completion of your installation a FENSA Certificate will be posted to you directly from FENSA within 6 - 8 weeks from the date of completion.

There are some exceptions a Fensa Certificate will not be required, these are as follows:-

- Doors installed are less than 50% glazed;
- All conservatories installed are excluded;
- Garage doors or doors installed within a garage are excluded;
- Planning Permission or Building Regulation Approval have been applied.

There are some exceptions that Planning Permission maybe required from your Local Authority, these are as follows:-
