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.

Common Questions
Climbing frames are classed as ‘outbuildings’ meaning they are classed as permitted development, not requiring an application provided they meet the limits set out in legislation. One of these limits is that they cannot be in front of the house.
The key restrictions for a climbing frame will be the height; how close it can be to the properties boundaries and where it can be located.
A full list of limits and conditions can be found on our outbuildings common projects.
If the climbing frame exceeds any of the limits set out in legislation an application for planning permission is required.
A single storey rear extension can fall under permitted development, meaning planning permission may not be required providing it meets certain criteria.
In terms of height, the extension must:
- Be no taller than four metres at its highest point
- Have eaves no higher than the eaves of the original house
- Not exceed the height of the original dwelling

Yes, but this type of conversion will require full planning permission. This is because you’d be changing the use of the ground floor from residential to commercial (typically to a use class such as E), while the upper floor would remain as a residential flat (Class C3). The change of use triggers the need for planning approval.

If you carry out development without the necessary planning permission, and it doesn’t fall within permitted development rights, you may be in breach of the planning rules. In such cases, you will usually need to submit a retrospective planning application to seek approval for the work already completed or started. However, there is no guarantee that permission will be granted.

Planning permission is not required if the home will be used as a short-term let for 90 days or less throughout the year.
If you plan on using the home as a short-term let for more than this time period, then you will need to apply for planning permission for a change of use.
If you rent a room in your property while you still live there, you will not require planning permission.
