Part 6: Agricultural & Forestry

This section (agricultural and forestry) allows erection, extensions or alterations of buildings; other required works; mineral working for agriculture and developments for forestry.

Part 6 is permitted development: in other words, planning permission is granted by the GPDO where the detailed limitations and conditions are met. Some forms of agricultural development also require a prior approval procedure before work starts.

It is broken down into four main sections for agricultural uses: land 5 ha and more, land under 5 ha, mineral working and forestry works.

The up to date legislation can be found in each section for Part 6. With a summary as required.

Before relying on Part 6, it is worth checking whether the land is genuinely agricultural or equestrian and what forms the agricultural unit.

The agricultural rights in Classes A to C depend on the relevant land being in agricultural use. Horse grazing can sometimes remain agricultural, but a materially different equestrian use does not acquire Part 6 agricultural rights merely because it takes place on rural land. See our agricultural or equestrian land guide.

The five sections within Part 6 are as follows:

Class A – agricultural development on units of 5 hectares or more

Class B – agricultural development on units of less than 5 hectares

Class C – mineral working for agricultural purposes

Paragraph D – Interpretation of Classes A to C

Class E – forestry developments

Class Q – Agricultural building to residential

Class R – Agricultural buildings to a flexible commercial use
