A delivery-only kitchen in an industrial unit: the rules

A delivery-only kitchen in an industrial unit almost always needs planning permission, and the application is decided on three things: extraction and odour, rider movements at night, and whether the estate can absorb a use that peaks when everything around it is closed. Customer footfall, which drives most hot food applications, is irrelevant here.

The use class question comes first and has no settled national answer, so resolve it with the council before you fit out the unit.

Whether the use is industrial or sui generis

Since the 2020 amendments to the Use Classes Order, a hot food takeaway is sui generis and sits outside every class. A delivery-only kitchen shares the cooking but not the shopfront, and councils have gone both ways: some treat it as sui generis because the primary activity is preparing hot food for consumption off the premises, others accept it as light industrial or storage and distribution where there is no public access at all.

That split matters because it decides whether you need permission at all. A unit already in Class B2 or B8 use may accommodate a food production operation without a material change of use if the activity is industrial in character, is not open to the public and does not bring in a stream of private vehicles.

Do not guess. Two routes are safer than an assumption: ask for pre-application advice in writing, or apply for a lawful development certificate under section 192 of the Town and Country Planning Act 1990 for the use you intend. A certificate is the only formal way to confirm that a use is lawful, and it is a great deal less expensive than an enforcement notice after you have installed a kitchen.

Where the council says sui generis, apply for full planning permission and design the application around the impacts below.

Extraction, odour and stack height

Kitchen extraction is the single most common reason these applications fail. An industrial unit was not designed for a commercial kitchen, and a flue bolted to the elevation and terminating below the roofline will be refused wherever there is a sensitive receptor nearby.

The expected approach is risk-based. Assess the separation distance to the nearest receptor, the type of cooking and the quantity of food, then specify the odour control to suit: grease filtration as a minimum, with electrostatic precipitation, carbon filtration or ultraviolet treatment added as the risk rises. Discharge should be vertical, unimpeded, at high level and clear of the roofline and any opening windows or air intakes.

The Ventilation and Extraction Statement should set out the kitchen schedule, the extract rate, the filtration train, the duct route, the termination height and discharge velocity, and the maintenance regime with cleaning intervals. Where the receptor distance is short or the cooking is high odour, expect to need a separate Odour Assessment as well.

Maintenance is part of the case, not an afterthought. A carbon filter that is never changed performs like no filter at all, and councils increasingly condition a maintenance log.

Rider arrivals, waiting and queuing

Delivery riders behave unlike customers. They arrive in waves tied to order peaks, they wait, and on mopeds they idle. An estate road with no formal waiting area gets riders parked across yard entrances and grouped at the unit door.

Design the waiting arrangement into the application. That means a marked rider waiting area within the site, cycle and moped parking with the numbers stated, a defined collection point, and a management plan covering what staff do when riders arrive early. Put the expected order volume at peak and the resulting rider numbers in the Transport Statement rather than leaving the officer to imagine them.

The estate's own service arrangements matter too. Swept paths for existing occupiers' HGVs should be checked against your waiting area, because a rider parking area that blocks an articulated vehicle's turning circle is an objection from a neighbour rather than from the council.

Noise at night on an estate boundary

Two sources drive the noise case: the extract fan and the riders. Fan noise is assessed against the background sound level using the method in BS 4142, and the night-time reference period of 15 minutes is unforgiving for plant that runs continuously.

Rider noise is harder because it is intermittent and human. Moped engines, horns, conversation and radios at 11pm carry a long way across an empty estate, and they are not well captured by a plant noise calculation. Deal with them through layout and management: keep the waiting area away from the boundary nearest any housing, prohibit engine idling in writing, and offer hours limits you can actually keep.

A Noise Impact Assessment should cover both, with the background survey run at the hours you intend to operate rather than during the working day.

An illustrative fit-out sequence

Take a 180 m² end-of-terrace unit on a trading estate, with the nearest houses about 60 m away across an access road. This example is illustrative only. The sensible order is to confirm the lawful use, then commission a background sound survey covering the evening and night hours you intend to trade, then design the extract route and termination against that survey and the receptor distance, and only then fix the internal layout. Doing it in the reverse order, which is what happens when the kitchen fit-out is designed first, usually ends with a flue that cannot be routed where the acoustic answer requires.

Waste, grease and pest control

Food production on an industrial estate produces waste streams the estate was not set up for. Show the refuse and recycling storage with capacity for the volumes generated, the collection arrangement and its frequency, the food waste route, and a grease management system with a trap or separator and a documented emptying schedule.

Pest control follows from waste, and the estate landlord will have a view as well as the council. A bin store that cannot be closed, or waste presented on the estate road overnight, generates complaints that end up at the council as a request to review the permission.

Hours and vehicle movement limits

Councils will usually condition the hours of operation, sometimes separately for cooking, for deliveries in and for rider collections. Propose your own envelope in the application, with the reasoning, rather than accepting whatever the officer drafts.

Be realistic about the late end. A kitchen serving a midnight market will be applying to vary the condition within a year if it accepts an 11pm cut-off, and a section 73 application to vary hours is decided against your compliance record. Ask for what the operation needs, evidenced, and offer monitoring in exchange.

Two conditions worth offering yourself: a rider management plan approved before first use, and a post-installation noise verification test for the extract plant once it is running. Both answer the officer's real worry and both are easier to accept than a refusal.
