You don't actually need to own land or property to apply for planning permission for it. This means you can apply for permission before deciding whether or not to buy a piece of land.

The following people must be informed about a planning application relating to land or buildings that they have an interest in:

• The owner or all the part-owner/s (if you are not the full owner)
• Any leaseholders with at least seven years' lease remaining
• Any agricultural tenants.

You can contact your local planning authority for pre-application advice or book an appointment with our Planning Guidance Service.

Raising your garden level a small amount is likely to not require planning permission as it is likely to have minimal impact on the chances of flooding or overlooking your neighbours.

Increases of over 30cm may require planning permission as a significant change can impact drainage or your neighbours. If the changes are close to a boundary, you should consider whether it will overlook your neighbours or be intrusive.

You should contact your local planning authority to understand whether your proposed changes will require planning permission.

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.

If the garage will remain in domestic use - for example, as a personal hobby or home workshop - then planning permission is typically not required.  

However, it’s important to check whether there are any planning conditions, covenants, or restrictions attached to your property or the garage itself that may limit or prevent conversion.
