Temporary rural worker's dwellings and the three year test

A temporary agricultural workers dwelling is the route for a new rural enterprise that cannot yet show three years of trading. Permission is granted for a limited period, conventionally three years, under section 72 of the Town and Country Planning Act 1990, on the basis that the business will have built a record by the end of it. The council is not approving a house. It is approving a trial, and the condition requiring removal at the end of the period is meant seriously.

When a temporary permission is the right route

Use it when the functional need is real but the financial evidence does not yet exist. A new dairy herd, a new poultry unit, a market garden in its first season: all can produce a genuine requirement for someone on site at night while having no trading history at all.

Do not use it as a softer version of a permanent application for an established business. Where three years of accounts exist, apply for the permanent dwelling and expect the temporary route to be treated as an attempt to avoid the financial test.

Do not use it where the real objective is a house. Inspectors see a lot of applications where a small flock of sheep appears six months before the application and the labour requirement calculation does not survive contact with the evidence. Those refusals are hard to recover from, because the next application is read against the first.

The new enterprise case and its evidence

The tests applied to a temporary dwelling for a new enterprise are well settled in practice. There must be clear evidence of a firm intention and ability to develop the enterprise. There must be a functional need. The enterprise must have been planned on a sound financial basis. The functional need must not be capable of being met by an existing dwelling on the unit or in the area. And the usual siting, access and design requirements must be satisfied.

The first of those is the one that distinguishes a temporary application from anything else. Firm intention and ability means money spent and commitments made, not a plan. Evidence that carries weight includes purchase or tenancy documents for the land, invoices for stock, buildings, fencing and equipment, a bank facility or a grant offer, contracts with buyers or processors, and relevant qualifications or experience.

Where the applicant has an existing farming business elsewhere and is expanding, say so plainly and show the connection. That history is an asset, not a complication.

What the business plan has to show

Write it for an agricultural consultant, not for a bank. The council will send it to one.

A usable plan sets out the enterprises and their intended scale, with stock numbers or cropped areas year by year for at least three to five years. It calculates the labour requirement against recognised standard labour figures for those enterprises, and it shows how that requirement maps onto the need for someone to be present outside normal hours. It gives a capital expenditure schedule and how it is funded, a projected profit and loss with stated assumptions on prices and yields, and a cash flow that survives a bad year.

Two things sink otherwise decent plans. Assumptions that cannot be sourced, and a labour calculation that quietly counts the applicant's off-farm income or unpaid family help without saying so. State both openly. A plan that admits the business will be tight in year two reads as credible. One that shows smooth growth from a standing start does not.

Siting a caravan or mobile home lawfully

Most temporary dwellings are caravans or mobile homes, and the planning analysis is about use of land rather than building operations. Stationing a caravan for residential occupation on agricultural land is a material change of use and needs planning permission in its own right.

Two definitions matter. A structure that meets the statutory definition of a caravan, including the twin-unit dimensions in section 13 of the Caravan Sites Act 1968, is a caravan however solid it looks. Something delivered in three pieces and assembled on site, or sitting on foundations, may be a building, which changes the application and the removal condition.

Site licensing under the Caravan Sites and Control of Development Act 1960 is a separate consent from the council, with exemptions that may apply on agricultural land. Check the position rather than assuming it, and note that the planning permission and the site licence can carry different conditions.

Put the caravan with the farm buildings. A unit sited at the far end of the holding with its own access and a hedge round it looks like a house and will be treated as one. Landscape evidence for a sensitive location is dealt with in the notes on landscape and visual evidence for a countryside application, and the access question is covered in the notes on farm tracks and new accesses.

What happens at the end of the temporary period

The condition will require the dwelling to be removed and the land restored by a stated date. Planning Practice Guidance on the use of conditions is clear that a limited period permission is exactly that, and the expectation is compliance.

Three outcomes are possible. The business has succeeded and you apply for a permanent dwelling. The business has not developed as planned and the caravan comes off. Or you apply for a further temporary period, which authorities dislike and inspectors scrutinise closely, because a second or third temporary permission starts to look like permanence by instalments.

Diarise the expiry date at the point of grant. Applications made after expiry are made from a position of breach, and that colours everything that follows.

Converting to a permanent permission

By the end of the period you should have the evidence the permanent tests require: three years of accountant-prepared accounts, a demonstrated functional need supported by the actual husbandry pattern, and a clear picture of what the business can afford.

Apply in good time, at least six months before expiry on a straightforward case and longer where the council's consultant is likely to want a site visit. Present the permanent application as the continuation of the temporary one, with a short narrative comparing what the business plan projected against what actually happened. Where the outturn is below projection, explain why and show the current trajectory.

The permanent permission will carry an agricultural occupancy condition. Understand its effect on value before you build anything more substantial than the caravan you already have. Your Planning Statement should deal with that condition directly rather than leaving it to the decision notice.

Common reasons temporary applications fail

In rough order of frequency: no credible evidence of investment already made, a functional need asserted rather than calculated, an existing dwelling on the unit or within a short distance that could serve, a business plan with unsourced assumptions, siting chosen for outlook rather than function, and a proposed unit far larger than the enterprise needs.

Add one more that is easy to fix. Services. A remote site needs a water supply, a foul drainage solution and power, and a temporary permission does not excuse any of them. The practical options and their consents are set out in the notes on water supply and foul drainage on remote rural sites.
