Whether you need planning permission to install an extractor fan depends on the size and placement of the fan.

For domestic installations, such as a bathroom or kitchen in your house, planning permission is not generally required. If the change significantly alters the external appearance of your home then permission may be required.

If you live in a listed building, you will need listed building consent for any significant changes.
