You might not be aware that certain commercial properties have specific use classes, as determined by the Town and Country Planning Order 1987. This outlines what a specific premises may be legally used for.
Planning permission is typically required from your local council’s Local Planning Authority (LPA) department if you wish to submit a ‘change of use’ application. Planning permissions is not necessary if the current and proposed uses fall within the same use classes. For example, if you are planning on turning a Class A1 hairdressing salon into another A1 retail store, it won’t be necessary. Nevertheless, if you wish to change a property’s commercial use class from A1 to A3 – perhaps to operate a café or restaurant where patrons can eat on-site – planning permission is needed.
Failure to obtain the necessary planning permissions to change a property’s commercial use class could lead to significant financial penalties.
