Farm shop and cafe: ancillary use or separate retail

A farm shop selling produce grown on the holding is usually treated as ancillary to the agricultural use, which means no planning permission is needed for the retailing itself. Start buying in stock from wholesalers, open to passing trade rather than to people visiting the farm, and put in a cafe with 30 covers, and the position changes. At some point the retail stops being incidental to farming and becomes a separate use in its own right, and that is a material change of use under section 55 of the Town and Country Planning Act 1990.

Where that point sits is a matter of fact and degree. There is no floorspace figure in the legislation and no percentage in national policy. What exists instead is a set of indicators that councils and inspectors use, and a farm that understands them can plan the growth of the enterprise without walking into an enforcement notice.

When retail is ancillary to the farm

The ancillary principle is straightforward in theory. A use that is subordinate to, and functionally linked with, the primary use of the land does not need its own permission. A farm shop in a converted dairy selling the holding's meat, eggs and vegetables to people who have come to the farm is a textbook example.

The link breaks down in three ways. The first is scale, where the shop grows to the point that it is the main commercial activity on the site. The second is sourcing, where most of what is sold has nothing to do with the holding. The third is independence, where the shop trades on its own hours, has its own staff, its own car park and its own customer base drawn from the road rather than the farm.

Any one of those can be survivable. Together they establish a retail use, and the honest advice at that point is to apply rather than to argue.

Floorspace and turnover as indicators

Councils look for proportion rather than an absolute threshold. The questions that get asked, in roughly this order:

• What proportion of goods by value comes from the holding, and what comes from within a defined local area?
• What is the retail floorspace compared with the agricultural floorspace and the land area of the holding?
• How many vehicle movements does the shop generate, and are they farm-related or retail trips?
• Is the shop staffed by the farm or by employees whose only role is retail?
• Does the shop open outside the working pattern of the farm?

Some local plans in rural districts set their own percentages for local sourcing in a farm shop policy, and where they do, that figure governs. Check the adopted plan first, because a locally set proportion is a much better guide than any general rule of thumb.

Turnover evidence matters more than most applicants expect. Where a use is contested, invoices and till records showing the origin of stock are the strongest evidence available, and they are worth keeping from the day the shop opens rather than assembling under pressure two years later.

Conditions tying sales to the holding

Where permission is granted, the condition that appears most often restricts sales to produce from the holding plus a stated proportion from a defined area, often expressed as a percentage of goods by value sourced within a set radius or county.

These conditions are enforceable, and they are checked. A condition requiring 60 per cent of goods by value to originate from the holding or from within 30 miles will be tested against purchase records if a complaint is made. Two practical points follow. Negotiate the wording before the decision rather than after, because a percentage that suits a seasonal vegetable operation may be impossible in February. And keep the records the condition implies, in a form that can be produced.

A condition may also tie the shop to the agricultural unit so that it cannot be sold off separately, restrict the retail floorspace to a stated area, or limit opening hours. National guidance on the use of planning conditions requires each one to be necessary, relevant, enforceable, precise and reasonable, so a condition that cannot be monitored is open to challenge at application stage.

Adding a cafe and what it changes

A cafe changes the character of the operation more than the floorspace suggests. Under the Town and Country Planning (Use Classes) Order 1987 as amended, retail sale of goods and the sale of food and drink for consumption on the premises both sit within Class E, so once a lawful retail use exists, adding a cafe within that use is often not a material change. Where the shop is ancillary to agriculture rather than a lawful Class E use, that flexibility is not available.

What a cafe brings with it is a set of practical issues that have nothing to do with use classes. Cooking smells need an extraction system, and a ventilation and extraction statement showing the flue route, termination height and odour control is what the environmental health officer will look for. Seating outdoors raises noise from customers, particularly in the evening. Deliveries increase. Waste storage grows, and it has to be screened and accessible for collection. Trade effluent from a commercial kitchen may need a separate arrangement with the sewerage undertaker.

Longer opening hours are usually the part that draws objections from nearby dwellings, and an hours condition is the normal outcome.

Parking and access on a rural road

Retail traffic on a road built for tractors is the issue that sinks more farm diversification applications than policy ever does. The highway authority will look at visibility splays at the access, the geometry of the junction, whether vehicles can enter and leave in forward gear, and whether the parking provided matches the trade proposed.

A transport statement is proportionate for most farm shop and cafe proposals. It should set out existing and proposed trip generation, the access geometry against the design speed of the road, parking layout including accessible bays and cycle parking, and servicing arrangements for deliveries. Where the access serves the farm as well, show how retail and agricultural traffic interact, because a car park that a combine has to drive through is a point an objector will make for you.

Speed surveys are sometimes needed to establish the visibility splay required. That is a cost worth incurring early rather than after a highways objection has already been lodged.

Signage on the approach

Advertisement consent is a separate regime under the advertisement regulations, and it is where otherwise careful applicants get caught. Small signs on the premises may benefit from deemed consent, but signs on the verge, on a neighbouring field, or at a road junction some distance from the site usually need express consent, and in a National Landscape or conservation area the assessment is stricter.

Signs placed without consent in the highway verge can also be removed by the highway authority. Plan the signage strategy at the same time as the application, and apply for what is needed rather than putting up a sign and waiting to see whether anyone complains.

Evidence to submit on origin of goods

For an application seeking to regularise or expand a farm shop, the pack that answers the ancillary question directly usually contains: a schedule of goods by category with the proportion sourced from the holding and from the defined local area, the retail floorspace and the agricultural floorspace with a plan showing both, projected trip generation, opening hours, staffing, and the proposed wording of a sourcing condition you can actually live with.

Where the proposal is large enough to raise town centre issues, a retail impact assessment may be required, though for most farm shops the scale is well below the national threshold and any local threshold in the development plan will be the relevant test.

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 under section 191 or 192 of the 1990 Act is the only formal way to confirm that an existing or proposed farm shop use is lawful.
