Planning permission for a delivery only kitchen

Dark kitchen planning permission usually starts with an argument about use class, and the honest answer is that the position is unsettled. A kitchen producing food solely for delivery has no visiting public, so it does not sit comfortably in Class E(b), which covers the sale of food and drink principally for consumption on the premises. It is not a hot food takeaway in the ordinary sense either, since customers never attend. Most councils treat it as sui generis and require a full change of use application, and planning on that basis is the safe course.

Which use class applies, and how to settle it

The Use Classes Order was amended in 2020, and hot food takeaways, where the sale of hot food is principally for consumption off the premises, became sui generis. A delivery only kitchen sits outside both that description and the restaurant description, because nobody buys anything at the premises at all.

Three arguments get made. That the operation is sui generis and needs express permission. That it is a light industrial or storage and distribution use, on the basis that food is manufactured and despatched. And that it remains within Class E where the unit was a restaurant and the kitchen is unchanged. Inspectors have looked at the facts of the operation rather than the label, and the facts that matter are the volume of despatches, the number of riders, the hours, and whether any member of the public ever attends.

The practical route is one of two. Apply for planning permission for a change of use to a delivery only kitchen, described precisely, and accept conditions. Or apply for a certificate of lawfulness of proposed use under section 192 of the Town and Country Planning Act 1990 if you have a real case that the use falls within the existing class. Starting without either, in a unit surrounded by flats, is how enforcement files begin.

Whatever the class, an intensification of use can itself be a material change. A restaurant kitchen serving forty covers a night is a different planning animal from the same kitchen despatching three hundred orders.

Odour and extraction, the issue that decides most applications

Environmental health will look at extraction before anything else, and a scheme without a designed system will be refused or held.

The national guidance on controlling odour and noise from commercial kitchen exhaust systems sets the framework. It works on a risk assessment: the type of cooking, the size of the kitchen, and the sensitivity and proximity of the nearest receptors determine the level of odour control required. A high risk site next to residential windows needs a fuller abatement train than a low risk site on an industrial estate.

The elements to show on drawings are specific. Grease filtration at the canopy. An abatement stage sized to the risk, which may be electrostatic precipitation, carbon filtration, ultraviolet or ozone treatment, or a combination. Ductwork routed and supported so it can be cleaned. And a discharge point at high level, normally terminating at or above the ridge of the building and above the eaves of nearby buildings, discharging vertically with no cowl that deflects the plume downwards.

A Ventilation and Extraction Statement setting out the system, the flow rates, the abatement stages and the maintenance regime is the document councils ask for. Where the setting is sensitive, or the cooking is high odour, an Odour Assessment applying the risk methodology properly is worth the cost, because it converts a subjective argument into an assessed one.

Maintenance is part of the case. Offer a condition requiring filter replacement and duct cleaning to a stated frequency, with records kept and available to the council. Officers approve schemes they believe will still work in two years.

Riders, waiting and highway safety

The rider question is what neighbours object to, and it is the one councils condition most heavily.

Design it out. Provide a waiting area inside the unit with seating, a toilet and phone charging, so that riders are not standing on the pavement. Provide parking for mopeds and cycles within the site, with charging points for electric machines. Set the collection point away from residential frontages and away from the junction.

Then evidence it. A delivery and servicing plan should state the expected number of orders in the peak hour, the split between moped, cycle and van, the number of riders on site at once, the routes to and from the site, and the arrangements for managing them. A marshal at peak times is a commitment councils take seriously.

Expect conditions restricting waiting on the highway, requiring the internal waiting area to be retained, limiting the number of delivery vehicles on site, and requiring the delivery and servicing plan to be complied with. Engine idling and horn use are usually covered too.

Where the unit fronts a busy road, the highway authority will want to see that riders can leave and return without conflict, and that any loading for supplies happens off the carriageway.

Noise from plant and from the operation

Two sources, assessed differently.

Fixed plant means the extract fan, the refrigeration and any air conditioning. The assessment is done under BS 4142, comparing the rating level of the plant against the measured background sound level at the nearest noise sensitive receptor, with corrections for tonality and impulsivity. A Noise Impact Assessment with measured background levels taken at the relevant times, including the small hours if the kitchen runs late, is the evidence base. Attenuators, anti-vibration mounts and acoustic enclosures are the usual mitigation.

Operational noise means moped movements, roller shutters, bin lids and voices. That is harder to model and better addressed by management: quiet delivery practice, restricting the use of the rear yard at night, fixing shutters open during trading hours, and siting waste storage away from bedroom windows.

Hours, and the amenity case

Delivery kitchens make their money late, and councils in residential areas restrict late hours. Ask for what the business actually needs rather than an optimistic maximum, and support it with the noise and rider evidence.

A pattern that often works is a two stage condition: full hours for the kitchen operation, with a tighter restriction on rider movements and on the use of external areas after a stated time. That gives the environmental health officer something enforceable and gives you a trading position.

Where a site is marginal, a temporary permission for a fixed period lets the council test the impact against the predictions. It is not ideal for funding, and it is often better than a refusal.

Waste storage and collection

Delivery kitchens generate a lot of packaging and food waste, and a bin store sized for the previous occupier will not do.

Show a store large enough for the containers your waste contractor will actually supply, ventilated, drained, with a wash-down point, sited away from residential windows and from the kitchen intake. State the collection frequency and the times, and keep collections outside the hours when neighbours are asleep. Food waste needs separate collection, and a written contract with a licensed carrier is worth submitting with the application.

The documents that make the case

A well evidenced application for a delivery only kitchen normally contains a Planning Statement that deals with the use class question directly rather than avoiding it, the extraction and odour evidence, the acoustic assessment, a delivery and servicing plan covering riders, a waste strategy, floor plans showing the internal rider waiting area, and elevations showing the flue and any external plant.

If you also intend customers to collect in person, the position changes again and the use may become a hot food takeaway, which brings its own policy tests. The same goes for adding seating: outdoor seating and the consents it needs is a separate question from the kitchen use itself. Food business registration with the council and any premises licence are separate regimes and do not substitute for planning permission.

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