What rules apply to installing an extractor fan?
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.
Larger extractor fans for businesses are likely to require an application for planning permission to be made to the local planning authority. These extractors can impact the local area due to their noise, visibility and odour, as such the planning authority will need to assess the change.
Building regulations relating to ventilation and electrical works will have to be complied with, these are covered by Approved Document F and P respectively.
