What is change of use?

Change of use refers to altering the way in which the premises are occupied. There are scenarios where changing the use will not require consent by the local authority, for example, a sandwich shop changing to a hairdresser (both are classified under A1 Shops). However, if you�re making significant changes (e.g. changing a residential property to a business premises), you will be required to obtain full planning permission to change the use of the property.
