Mobile homes and caravans on agricultural land

Putting a caravan on a field is usually development, and the fact that a caravan has wheels rarely saves it. What matters is whether the use of the land has materially changed, and stationing a residential caravan on agricultural land changes the use from agriculture to something else. Councils enforce against this regularly, and the argument that nothing was built does not succeed.

There are real exemptions, and there is a route to a temporary permission for a working farm. Both are narrower than the internet suggests.

When stationing a caravan is development

A material change of use is development under section 55 of the Town and Country Planning Act 1990, and the question is one of fact and degree. A caravan brought onto a field for a few days during harvest and taken away again is usually part of the agricultural use. A caravan connected to services, sitting on hardstanding, with a fence around it and a car parked beside it, is residential use of agricultural land.

Physical works push the same way. Laying a hardstanding, forming an access, installing a septic tank or erecting a boundary fence are each operational development, and they turn what might have been an arguable temporary use into a visible and datable one.

The caravan itself can also become a building in law if it loses its mobility, though the test used in enforcement cases looks at whether the structure remains a caravan within the statutory definition rather than at whether anyone intends to move it. Our note on field shelters and whether they are development covers the same question for structures on skids.

Exemptions for agricultural and forestry workers

Caravan legislation and planning legislation run separately, and the exemptions people quote usually come from the licensing side. The Caravan Sites and Control of Development Act 1960 exempts several situations from the need for a site licence, including caravans occupied by agricultural or forestry workers on the land where they work, caravans on building and engineering sites, and use within the curtilage of a dwelling house.

Two points are constantly misread. A site licence exemption is not a planning permission, so land exempt from licensing may still need permission for the change of use. And the agricultural worker exemptions are tied to seasonal or site related occupation connected with the work, not to a permanent home for a family member who helps at weekends.

The 28 day rule is also commonly misapplied here. The temporary use right in Part 4 of the General Permitted Development Order allows land to be used for any purpose for 28 days a year, but it does not authorise a residential use, it does not cover the use of a building, and it does not run with a caravan that never leaves.

Temporary permissions for a farm business

The established route for a rural worker who needs to live on site is an application for a temporary dwelling, usually a caravan, for a defined period while the enterprise proves itself. National policy allows isolated homes in the countryside where there is an essential need for a rural worker to live permanently at or near their place of work, and temporary permissions are used to test that need.

A temporary permission commonly runs for three years, with a condition requiring the caravan and any works to be removed at the end unless a permanent dwelling is approved. Officers use the period to see whether the business is viable and whether the need is real.

Do not treat a temporary permission as a step towards a house by default. It is a test, and enterprises that fail it are expected to remove the caravan.

Evidence of functional need

The application stands or falls on functional need: why someone has to be present on the land at unsocial hours or at short notice. Livestock enterprises with calving, lambing or foaling make the argument more easily than arable or equestrian livery, and officers expect specifics rather than assertions about security.

A convincing submission covers the enterprise and its scale, the tasks that require attendance outside working hours and how often they arise, the numbers of animals and their management calendar, the distance to the nearest suitable existing accommodation and why it will not serve, and the financial position of the business including accounts and projections.

Independent appraisal helps. Many authorities commission their own agricultural consultant to review the case, and a submission prepared by a rural surveyor with the accounts attached gets a better reception than one written by the applicant. The planning statement is where the policy argument is drawn together.

Site licensing under caravan legislation

Where a site licence is needed, it comes from the local authority under the 1960 Act, and a licence cannot be issued for land without planning permission for that use. The two run in sequence: permission first, then licence.

Licence conditions deal with spacing between units, fire points, water supply, drainage, roads and hardstandings. They are practical requirements and they can affect the layout, so on any scheme with more than one unit it is worth checking the licensing standards before the layout is fixed rather than after permission is granted.

Sites occupied by a single agricultural worker under an exemption avoid the licence, but as noted above the exemption says nothing about the planning position.

Duration, conditions and removal

Expect conditions that tie the caravan to the enterprise and to a person. Common wording restricts occupation to a person solely or mainly employed in agriculture on the holding, and to their dependants, and requires removal of the caravan and reinstatement of the land within a stated period after the permission ends or the occupation ceases.

Removal conditions are enforceable and councils do pursue them. Plan for the reinstatement: services capped, hardstanding lifted, fencing removed, soil made good. Where the land is best and most versatile, reinstatement to agricultural condition matters, and handling the soil properly is the difference between restoration and a compacted patch.

Where circumstances change, the route is a fresh application rather than quiet continuation. A caravan left in place after the period expires is a breach, and the ownership position has to be correct too, as our note on ownership certificates and agricultural notices explains for tenanted land.

Enforcement and immunity questions

Unauthorised residential caravans are a common enforcement subject, and the immunity rules are less generous than they used to be. The Levelling-up and Regeneration Act 2023 extended enforcement time limits in England so that the four year rule for most breaches gives way to a ten year period, and the date from which that applies to a particular breach needs checking rather than assuming.

Concealment is treated seriously. Where a breach has been deliberately hidden, an authority can apply for a planning enforcement order allowing action outside the normal time limits, and the courts have supported that approach.

If you are already in this position, take advice before making an application, because an application can establish the date and nature of the breach. A certificate of lawfulness is the formal route where genuine immunity exists.

PlanScope drafts the narrative planning documents for rural applications and flags where facts are missing. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval. Agricultural appraisals and financial evidence should come from a suitably qualified rural professional.

This is general guidance, not legal advice. Whether a change of use has occurred is a matter of fact and degree, and a lawful development certificate is the only formal way to confirm that a use is lawful, so check with your local planning authority or a qualified professional before relying on this.
