Part 3: Changes of use not requiring planning permission

Part 3 of the General Permitted Development Order 2015 (GPDO) relates to the changes of use.

However not all changes of use require the use of the GPDO.

Planning permission is not needed when the existing and the proposed uses fall within the same ‘use class’, or if The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) (GPDO) says that changes of use is permitted to another specified ‘use class’.

For example, a greengrocer’s shop could be changed to a shoe shop without the need for planning permission as these uses fall within the same ‘use class’, and a restaurant could be changed to a shop or a estate agency as the GPDO allows this type of change to occur without requiring planning permission.

Whilst a change of use might not need permission, any external building work associated with a change of use may still require planning permission.

Changes of use approved

The tables mentioned below of permanent changes in Schedule 2 Part 3 simplifies the complex legislation and should be read as a guide only, and in conjunction with the additional comments and restrictions on both those pages and also within each separate class within Part 3.  In addition to the permanent permissions within Part 3, there are a number of temporary changes in Schedule 2 Part 4 these are covered here.


We have two quick reference tables to assist you in changes of use via the GPDO. 

1 – Changes of use via use class – see what options exist for your building in a particular use class

2 – Where you can use the GPDO to change the use. Can you use it in a Conservation Area or AONB for example?
