Hot food takeaways: sui generis and the Class E boundary

The hot food takeaway use class is not a class at all. Article 3(6) of the Town and Country Planning (Use Classes) Order 1987, as amended in 2020, makes the use of premises as a hot food takeaway, where the food is mostly consumed off the premises, sui generis. Restaurants and cafes sit in Class E(b), where food and drink is sold principally to visiting members of the public and mostly consumed on the premises. So the boundary between the two is decided by where the eating happens, not by what is cooked.

That single test governs whether you need planning permission, and it is more slippery in practice than it looks on paper.

Why the distinction exists

Before September 2020, takeaways were Class A5 and restaurants were A3. The 2020 reorganisation swept restaurants into the broad Class E alongside shops, offices, gyms and clinics, and left takeaways outside it.

The reasoning is that takeaways generate a different set of effects: concentrated evening and late-night activity, frying odour, litter on nearby streets, and short-stay parking with engines running. Councils wanted to keep control of those, and sui generis status means every change into or out of the use needs an application.

The practical consequence for an occupier is that flexibility runs one way only. A restaurant can become a shop, an office or a gym with no application. A takeaway can become nothing without one.

Where a restaurant ends and a takeaway begins

The test is proportion. A restaurant with a collection counter and a delivery arrangement remains within Class E(b) provided consumption is mostly on the premises. When most of the food leaves the building, the character of the use has changed and it has become sui generis.

Nobody counts covers with a clipboard. What councils look at is the physical arrangement and the trading pattern: the number of seats against the size of the kitchen, whether there is a dedicated collection area, the presence of delivery riders waiting outside, opening hours running past the restaurant pattern, and the proportion of turnover taken through delivery platforms.

That last one has moved sharply in the past decade, and it is where enforcement cases now start. A restaurant that took ten per cent of its trade as collection in 2015 and takes seventy per cent as delivery today has probably undergone a material change of use, whatever the sign above the door says.

If you are buying or leasing, get the position confirmed. A certificate of lawfulness under section 191 or 192 of the Town and Country Planning Act 1990 is the only formal way to establish it, and it is a great deal less expensive than an enforcement notice.

Delivery-only kitchens

Kitchens serving only delivery, with no customer entering the premises, do not fit Class E(b), because that class describes sale principally to visiting members of the public. Councils have generally treated them as sui generis, and the position has been worked out through appeal decisions rather than settled by the Order itself.

The planning issues are different from a shopfront takeaway. Rider parking and waiting, movements late at night, and the effect on a residential area of an industrial unit generating a hundred motorcycle trips an evening. Where one is proposed on an industrial estate, the employment land policy and the highway effects will drive the decision as much as the use class point.

Extraction and odour

This is what actually decides most takeaway applications, and it is worth more attention than the use class analysis.

A Ventilation and Extraction Statement should give the kitchen layout and cooking equipment, the extract volume, the duct route and construction, the termination height and direction, the filtration and odour control specification, and the maintenance regime. Ducting that terminates at low level on a rear elevation, below the eaves of neighbouring flats, is the single most common reason for refusal.

Odour control is selected by risk. A high-risk operation, meaning heavy frying or charcoal grilling close to residential windows, needs more than grease filters: typically a multi-stage arrangement with pre-filtration, carbon or equivalent treatment, and a discharge at least a metre above the highest part of the adjoining roofline, pointing upwards without a cowl deflecting it back down. Where the risk is contested, an Odour Assessment that scores the risk and specifies the abatement to match it settles the argument better than a specification sheet alone.

Design the duct route before you sign the lease. Retrofitting a riser through three floors of flats above a shop unit is sometimes impossible, and it has killed more takeaway schemes than policy ever has.

Noise, hours and litter

Extract fans run all evening. A Noise Impact Assessment with a measured background level and a rating level for the fan and any refrigeration plant is what environmental health will want, together with attenuation details.

Expect conditions on opening hours, on the hours of deliveries and waste collection, on the extract system being installed and maintained as approved, and on litter. Litter conditions typically require a bin at the frontage and a periodic sweep of the surrounding streets, and they are enforceable.

Hours are the term worth negotiating hardest. A licence for late-night refreshment beyond 23:00 is a separate consent under the Licensing Act 2003, and a planning permission that closes at 23:00 makes the licence worthless.

Health policies near schools

National policy supports planning policies that promote healthy communities, and a number of authorities have adopted supplementary guidance restricting new hot food takeaways within a defined walking distance of schools, or in wards with high rates of childhood obesity.

Check the local document rather than assuming. The distances, the measurement method, whether it is measured from the school gate or the boundary, and any exceptions for units in designated centres all vary by authority, and the policy is often the reason an otherwise acceptable application is refused.

Where a health policy applies and the site is marginal, a Health Impact Assessment that engages with the local evidence base is the document that gives the officer something to weigh. It will not overturn a clear policy conflict.

Illustrative example. A vacant Class E unit on a parade, with two flats above in the same ownership, proposed as a fried chicken takeaway. The scheme that works has the duct run internally through a boxed riser in the rear corner of the unit and up the flank wall to terminate a metre above the ridge, three-stage odour treatment sized for the fryer bank, an attenuated fan set in an acoustic enclosure at roof level, closing at 23:00 with an application for a licence to match, and a litter bin fixed at the frontage. The scheme that gets refused is the same operation with a grille at first floor level on the rear elevation. Details here are illustrative.

Protecting a lawful takeaway use

Sui generis status makes an existing lawful takeaway a valuable consent, and there are three ways to lose it.

Abandonment, where the use ceases for a long period and the premises are altered or occupied differently. A condition on the original permission restricting the use or the hours in a way that later becomes commercially fatal. And a change of use to something else, which cannot be reversed without a new application.

Keep the paperwork: the decision notice, the conditions, evidence of continuous trading, and the extract system's approval and maintenance records. If the premises are going dark for a period, take advice before you strip out the kitchen.
