Reports for a farm shop and cafe on a holding

A farm shop selling mostly what the holding produces can be ancillary to the agricultural use. A farm shop selling mostly bought-in goods is a retail use that needs planning permission in its own right, and adding a café makes it a mixed use with the café as a separate element. The proportion of produce from the holding is the fact that determines which of those you are, and it is the fact the council will ask about, so evidence it before you apply rather than after.

Beyond that, the application turns on parking and access on a rural road, drainage for food preparation, and extraction for the café.

Ancillary retail against a free-standing shop

There is no statutory percentage. Whether sales are ancillary to agriculture is a question of fact and degree, judged on the character of the use as a whole: the proportion of turnover and floor area given to own produce, whether the shop has its own identity and advertising, its opening hours relative to the farm, the extent of bought-in goods, and whether it draws trade that would not otherwise come to the holding.

In practice most authorities treat a shop with a substantial majority of own or locally sourced produce as ancillary, and a shop stocked largely from wholesalers as retail. Where the mix shifts over time, as it usually does, the use can become a material change without anyone applying for anything, which is the enforcement risk.

The sensible approach for a serious farm shop is to apply for permission for the retail and café use rather than rely on an ancillary argument that gets harder to sustain as the business grows. A permission with a clear description is also what a lender and an insurer want to see. Our checklist for reports on a livestock building on a working farm covers the evidence discipline that applies across a working holding.

Sourcing evidence and the proportion grown on site

Where you do rely on an ancillary or part-ancillary case, or where a policy on farm diversification requires a link to the holding, the evidence has to be real.

• turnover split by own produce, locally sourced produce and bought-in goods, from the accounts
• floor area allocated to each category, shown on a plan
• a list of suppliers with their distance from the holding
• cropping and livestock records showing what the holding produces
• a sourcing policy, which can be offered as a planning obligation or secured by condition

That last point is worth considering. Where an authority is nervous about a rural retail unit becoming a general convenience store, a condition or obligation limiting the proportion of bought-in goods, or restricting the goods that may be sold, is often what makes the permission possible. It is restrictive, so negotiate the wording carefully, but it beats a refusal.

Expect the authority to test the retail impact where the shop is large. The sequential and impact tests in national policy apply to retail development outside town centres above a threshold, with a default floorspace figure in national policy unless the local plan sets its own, so a substantial farm shop may need a sequential assessment showing no suitable sequentially preferable site is available.

Parking and access on a rural road

The highway issues are the most common reason these applications are resisted, and they are entirely evidenceable.

The last row matters more than people expect. A yard where customers walk between parked cars and a telehandler is a genuine safety objection, and a layout that keeps the two apart, with a separate customer entrance where possible, answers it.

Where the approach is a single-track lane, passing places and a signing strategy may be needed, and improvements in the highway require a section 278 agreement with the highway authority. Build the time and cost of that into the programme.

Drainage and food preparation requirements

A shop with a chiller, a butchery counter or a café kitchen produces trade effluent with a higher organic load than a farmhouse, and in an unserviced location that is a planning issue as well as a regulatory one.

Where there is no mains foul sewer, the options are a package treatment plant with a drainage field, a treatment plant with a consented discharge to a watercourse, or a cesspool with tankered removal. Small sewage discharges may fall within the general binding rules where the conditions are met, and a permit is needed otherwise. A grease trap is normally required for a commercial kitchen regardless of the disposal route.

Carry out percolation testing before fixing the layout. A drainage field needs space, a set distance from watercourses, boreholes and buildings, and suitable ground, and discovering that the one available space fails percolation testing after the plans are drawn is the common and avoidable mistake.

Surface water from the new parking area needs its own strategy. Permeable surfacing, a swale along the edge of the parking, or a basin in a low corner, sized with a climate change allowance from the current Environment Agency figures, is the usual answer.

Extraction and odour for the café

A café serving cooked food needs a kitchen extraction system, and its discharge point is a design decision that is awkward to change later.

The elements the environmental health officer will look for: a ductwork route and termination point, normally discharging at high level and clear of nearby openings and dwellings, filtration appropriate to the cooking type with grease filtration as a minimum and carbon filtration where frying or char-grilling is proposed, a fan selected for the duty with acoustic attenuation, and an odour assessment scaled to the sensitivity of the surroundings.

On an isolated holding with no dwellings nearby other than the farmhouse, a short qualitative appraisal is usually proportionate. Where there are converted barns in separate ownership within a short distance, which is very common on diversified holdings, expect a proper assessment and expect the neighbours to comment.

Put the flue on the elevations in the application. A vertical duct up the side of a stone barn is a heritage and design issue as well as a technical one, and resolving it at design stage usually produces a better answer than a condition requiring details to be agreed.

Signage on the highway approach

Advertisement consent is a separate regime under the advertisement regulations, and it is commonly overlooked until a sign has already been installed.

Some signs benefit from deemed consent within the limits in the regulations, including certain signs on business premises and some directional signs, but a sign in the highway verge, an illuminated sign, or a sign above a stated size will usually need express consent. Signs within the highway also need the highway authority's agreement, and tourism signing from a main road follows the highway authority's own policy for brown tourist signs, with its own criteria and charges.

Deal with signage in the planning application as a separate advertisement consent application submitted at the same time. The fee is small, it avoids an enforcement letter, and an approved sign is worth more than an unapproved one you have to take down in your opening month.

Hours and seasonal variation

Hours conditions are where the negotiation usually lands, and they are easier to shape at application stage than to vary later.

A workable position: opening hours that reflect the actual trading pattern rather than an optimistic maximum, delivery hours restricted away from early mornings where dwellings are close, and a provision allowing extended hours for a stated number of seasonal days a year, such as a Christmas period or a pick-your-own season. Authorities grant seasonal flexibility readily when it is asked for specifically and refuse it when it arrives as a request to vary a condition two years later.

Be realistic about the café hours too. A café condition closing at 4pm forecloses evening events, and if evening trading is part of the plan it should be in the application with the noise and lighting evidence to support it.

A planning statement addressing the development plan's rural diversification, retail and tourism policies, with the highway, drainage and odour evidence cross-referenced, is the core of the submission. Our checklists for a self-build plot on a serviced site and for equestrian use in the Green Belt cover the comparable evidence questions on other rural proposals.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
