Agricultural to equestrian: which use applies

Keeping horses is not agriculture. Grazing them is. That single distinction, drawn in the definition of agriculture in section 336 of the Town and Country Planning Act 1990 and worked out in the courts, decides whether you need planning permission for what you are doing with a field.

Turning horses out onto grassland to eat the grass is the use of land as grazing land, which the definition includes, so it is agricultural. Keeping horses on land for riding, exercising, training, competing or boarding is something else, and a change from agriculture to that use is a material change of use requiring permission.

Why keeping horses is not agriculture

The statutory definition of agriculture covers the breeding and keeping of livestock, and livestock in this context means creatures kept for the production of food, wool, skins or fur, or for use in the farming of land. A riding horse is none of those. A working horse used to farm the land would be, which is a distinction of historical rather than practical interest.

The definition separately includes the use of land as grazing land. So the grass matters. Where the horses are on the field because the field is feeding them, the use remains agricultural. Where the field is where they live and are ridden, it is not.

Two practical indicators the planning officer will look at. Supplementary feeding of hay or hard feed suggests the land is no longer feeding the animals, so the grazing characterisation weakens. And the presence of jumps, a school, a manège, hard standing, rugs, a muck heap, a tack store or floodlighting all point to keeping rather than grazing.

Where grazing ends and keeping begins

It is a question of fact and degree, judged on the whole of what is happening, and there is no unit-per-hectare rule that settles it.

The middle rows are where most disputes sit, and the honest position is that officers differ. Where the use has been established for a long time, a lawful development certificate is the only way to settle it, and that is worth doing before you sell or borrow against the land.

Stables, field shelters and hard standing

A permanent stable block is a building, and its erection is development needing permission. The agricultural permitted development rights in Part 6 of Schedule 2 to the General Permitted Development Order 2015 do not help, because those rights apply to agriculture and equestrian use is not agriculture. That catches people who assume a farm's existing rights extend to a new stable.

A field shelter can escape being a building if it really is mobile, which turns on its size, its method of construction, whether it rests on or is fixed to the ground, and the degree of permanence in practice. A shelter on skids that is moved between paddocks is arguable. The same shelter bolted to a concrete pad, with the wheels removed and a water supply run to it, is a building.

Hard standing is development. So is a manège, which is usually an engineering operation involving excavation, drainage, a membrane, a sub-base and a surface, plus post-and-rail fencing and sometimes lighting. Each element needs to be shown and described in the application, and the drainage outfall needs an answer.

Commercial livery and riding schools

Commercial equestrian use falls outside the use classes altogether, so it is sui generis, and that brings two consequences. There is no permitted change into or out of it, and the description of development matters enormously because the permission will be read narrowly later. The broader point about uses that belong to no class at all applies directly here.

Distinguish the models in the application. DIY livery, where owners come to the site to care for their own horses, generates the most vehicle movements at unsocial hours. Full livery generates fewer visits but more staff. A riding school generates lesson traffic in blocks and needs parking for trailers. A competition or events use is different again and should be applied for explicitly rather than hoped for.

Officers will want hours, numbers of horses, numbers of staff, numbers of daily visits and the arrangements for muck. Answer all six or they will be conditioned on assumptions.

Green Belt and landscape considerations

National Green Belt policy treats the provision of appropriate facilities for outdoor sport and outdoor recreation as capable of being not inappropriate development, provided openness is preserved and the policy's other requirements are met. Equestrian use is usually approached on that footing, so the argument is about openness and scale rather than about principle. Cite the current edition of the Framework, which was re-issued in August 2026 with policy-coded chapters, and check the code against that edition rather than copying a paragraph number from an older document.

What harms openness in practice: post-and-rail subdivision of open fields, white fencing, a large manège with a pale surface, floodlighting columns, horsebox parking, jumps left out year-round, and the accumulation of field shelters. What helps: siting near existing buildings, using a darker surface, native hedgerow boundaries rather than timber, and no lighting.

In a National Landscape or National Park the same list applies with more force, and lighting will usually be resisted outright.

Access and traffic generation

Equestrian traffic is characteristically light in volume and awkward in nature. Horseboxes and trailers need visibility splays and turning space that a field gate does not provide, and the highway authority will look at the junction rather than at the trip numbers.

Where the use is commercial, a Transport Statement is usually proportionate, covering the access geometry, visibility, on-site parking and turning, and the daily and peak movements by category of user. Where the access is onto a fast rural road, expect the visibility requirement to drive the cost of the whole scheme.

What the application should include

1. A description of development naming every element: change of use, stables, manège, hard standing, fencing, lighting.
2. A Planning Statement setting out the use characterisation, the policy position and the operational details.
3. Drawings showing the manège construction section and the drainage, not just its outline on a layout.
4. A muck management note, including storage location, separation from watercourses and removal arrangements.
5. Lighting details or an explicit statement that none is proposed.
6. Landscape mitigation, with planting that will actually be maintained.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. A Lawful Development Certificate is the only formal way to confirm that an existing use is lawful.
