Class Q permitted development

Generally it is up to a local planning authority to decide whether to allow a particular development or not. However, in England and Wales, the Town and Country Planning (General Permitted Development) Order 1995 enables central government to permit certain types of developments known as permitted developments.

These are generally minor changes to existing properties. However, in 2014 Class Q permitted development was introduced. This permits the change of use of some types of buildings from agriculture to residential use. The Town and Country Planning (Use Classes) Order categorises uses of land and buildings. Generally, developments may not be used for purposes that are not within the use class for which they received planning permission.

The Town and Country Planning (General Permitted Development) (England) Order 2015 states that class Q consists of:

Exclusions include:

The developer must apply to the local planning authority for a determination as to whether the prior approval is required.

From 6 April 2018, amendments increased the thresholds for class Q permitted development, allowing:

  • Three larger homes, with a combined maximum floorspace of 465 square metres.
  • Five smaller homes, each less than 100 square metres.
  • A combination of the above, to a total of no more than five homes, of which no more than three may be larger homes.
