What are use classes and change of use?
Categorising land and buildings according to their type and purpose is known as Use Classes.
A 'Change of use' can be within the same Use Class or from one Use Class to another.
You will need planning permission for certain changes to the use of a property such as changing from a residential use to a business use. However, it is possible to change use between some classes without having to make an application for planning permission.
Depending on the specifics of any proposed change of use, including any building work associated with the proposal, an application for planning permission or prior approval may be required.

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).
