Use class designation for land and buildings

The Town and Country Planning (Use Classes) Order categorises uses of land and buildings. Developments may not be used for purposes that are not within the use class for which they received planning permission.

Changing the use of a development from one class to another may require planning permission, although changes of use may be permitted without the need for a planning application for certain allowable uses (for example, changing a restaurant into a shop).

For a schedule of permitted use class changes, see guidance on the Planning Portal and Permitted development.

Use classes are defined as follows (see The Town and Country Planning (Use Classes) Order Schedule):

A1. Shops - Shops, retail warehouses, hairdressers, undertakers, travel and ticket agencies, post offices, pet shops, sandwich bars, showrooms, domestic hire shops, dry cleaners, funeral directors and internet cafes
