Planning permission for a roadside coffee kiosk

A roadside coffee kiosk needs planning permission in almost every case where it trades from the same spot week after week. The operator's usual argument, that the unit is a trailer and moves, holds only while the unit really does move and the land is not being used for selling coffee on a settled basis. Once the pitch becomes the business, you are looking at a material change of use of the land, and quite possibly at operational development as well.

The decision then turns on highway safety more often than on anything else. A kiosk in a supermarket car park is a straightforward application. The same kiosk in a lay-by on a 60 mph A road is not.

Whether a kiosk is development at all

Two separate questions, and both have to be answered.

The first is whether the unit is a building. Structures are assessed on size, permanence and the degree of physical attachment to the ground, and a substantial cabin craned into position, levelled on blocks and connected to services will normally be a building however many wheels it started with. A small trailer towed off site each night generally is not.

The second question is about use. Using a piece of land for the retail sale of drinks and food is a use, and if that use is materially different from what the land was lawfully used for before, it is development regardless of the structure. A verge, a field corner or a corner of a haulage yard being used for a coffee business is a change of use.

So an operator can be entirely right that the trailer is not a building and still need permission for the use.

The 28-day rule and what it really gives you

Part 4 of Schedule 2 to the General Permitted Development Order permits the use of land for any purpose for a limited number of days in a calendar year, together with the provision of moveable structures for that use. The allowance is capped, reduced for certain uses, and further restricted on designated land.

Three things make it less useful than it sounds for a coffee business.

It is a calendar year allowance across the whole planning unit, so trading three days a week exhausts it before the spring. It does not authorise anything that amounts to operational development, so a hardstanding, a service connection or a fixed canopy falls outside it. And using the right does not make the use lawful afterwards, so the day you exceed the allowance you are in breach and the council can act.

It is a route for a seasonal pitch or a trial. It is not a route for a permanent business, and councils in areas with a lot of roadside trading watch the day counts closely.

Which use class you are in

Describe the use precisely in the application, because the classification is not always obvious.

A unit selling drinks and pre-made food for consumption off the premises, with no seating, sits awkwardly between the broad commercial class that covers cafes and restaurants and the separate treatment given to hot food takeaways. Councils take different views, and the difference matters later: it determines what you can change to without a further application, and whether the local plan's policy on hot food uses near schools applies to you.

The practical approach is to agree the description with the case officer before submitting, and to apply for a use described by what you actually do. A permission for a use described accurately is worth more than an argument won about a class.

Where seating is provided, even a couple of picnic benches, say so. Seating changes the character of the use, the litter profile and the parking demand, and an application that is silent about it invites an enforcement complaint later.

Highway safety and the lay-by

This is where roadside applications fail.

The highway authority looks at whether vehicles can leave and rejoin the carriageway safely, whether the visibility at the point of entry is adequate for the road speed, whether customers will stop on the verge or the carriageway when the parking fills, and whether pedestrians crossing between parked cars and the kiosk create a hazard.

On the strategic road network, National Highways applies a restrictive policy to new or intensified accesses, and a lay-by on a trunk road is provided for driver rest rather than for retail. Expect an objection unless the proposal is supported by a clear safety case.

Evidence that helps:

• Speed survey data rather than the posted limit, since the visibility standard follows actual speeds.
• A drawing showing parking layout, the number of spaces and how a vehicle turns.
• A swept path analysis for the largest delivery vehicle.
• Photographs showing existing informal parking, which sometimes demonstrates that the proposal formalises something already happening.

On anything more than a handful of spaces, a Transport Statement setting out trip generation and access geometry is worth preparing even where the council has not asked.

Litter, servicing and waste

Litter is the objection neighbours raise and the officer takes seriously, because a roadside food unit generates cups and wrappers that end up in hedgerows for a quarter of a mile.

Deal with it in the application. Offer bins at stated positions with a stated emptying frequency, a daily litter pick within a defined radius, and a named responsible person. Councils will condition this, and a proposal that already contains it is easier to approve.

Servicing needs the same treatment: where deliveries park, how often they come, and where the waste is stored between collections. A short Waste Management Strategy covering storage, segregation and collection removes a line of objection on any site where the bins would be visible from the road.

Welfare and water supply also come up. A unit with no mains water needs a documented arrangement for fresh water and waste water, and environmental health will ask about it under food hygiene requirements even though that is a separate regime.

Noise, generators and power

A diesel generator running from six in the morning next to housing is the fastest route to refusal.

Where a mains connection is possible, propose it and say so. Where it is not, specify the generator, give its sound power level from the manufacturer's data, and show the separation distance to the nearest noise sensitive property. On a site within 100 metres of housing, expect environmental health to want a Noise Impact Assessment using the standard method for assessing industrial and commercial sound.

Extraction is usually modest for a coffee unit, but any hot food preparation brings odour into play, and a Ventilation and Extraction Statement setting out the system, filtration and discharge point is the document that answers it.

Signage, conditions and renewal

Advertisement consent is a separate application. A frame sign, a flag and menu boards may each need it, and enforcement on roadside signage is comparatively active because highway authorities dislike distraction.

Councils frequently grant a temporary permission for a roadside unit, commonly for a year or three years, so the effects can be assessed. That is workable, but read the conditions: a requirement to remove the unit and restore the land at the end of the period is normal, and a business built on a temporary consent is harder to sell or finance.

Expect conditions on hours of opening, the number of vehicles parked, litter management, no external lighting beyond what is approved, and removal of the unit if the use ceases for a stated period.

Apply for renewal well before expiry, with evidence from the trading period: litter records, absence of complaints, accident data from the highway authority. That evidence is what turns a temporary consent into a permanent one.
