Walkthrough: shop to hot food takeaway change of use

A takeaway change of use walkthrough starts with one fact that decides everything else: a hot food takeaway is sui generis under the Use Classes Order, so moving a shop or a cafe into that use is a material change of use needing planning permission. There is no permitted development right that gets you there, and Class E flexibility does not extend to it.

What follows is illustrative. The unit, the consultee responses and the conditions are invented to show the sequence and the evidence. A real application will differ.

The unit and its existing use class

A ground floor unit of about 78 m² in a parade of eight shops on a secondary high street, with two flats above in separate ownership, a small rear yard reached through a shared service lane, and unrestricted on-street parking with a two hour limit during the day.

The last lawful use was a greetings card shop, which is Class E. Establishing that mattered: the applicant checked the planning history, the business rates description and the previous tenant's lease before assuming it. Where the lawful use is unclear, a certificate of lawfulness for the existing use resolves it before money is spent on anything else.

Two flats directly above a proposed hot food use is the single biggest constraint on this kind of application, and the applicant knew it from the start.

Why the move is out of Class E

Class E, introduced by the 2020 amendment to the Use Classes Order, is broad. It takes in shops, financial and professional services, cafes and restaurants where food is consumed mainly on the premises, indoor sport, medical uses, creches, offices, research and light industry. Movement between those is not development.

Hot food takeaway for consumption off the premises sits outside it, as a sui generis use. So does a drinking establishment, and so does a drinking establishment with expanded food provision.

The line between a cafe and a takeaway is about the primary use rather than the menu. A cafe with tables that also sells food to take away remains within Class E where consumption on the premises is the main activity. A unit with a counter, a warming display and two chairs is a takeaway whatever it is called. Officers look at the layout, the seating capacity, the opening hours and the delivery arrangements, and they are rarely persuaded by a floor plan showing four seats in a corner.

The applicant here made no attempt to argue otherwise and applied for a change of use to sui generis hot food takeaway. That decision saved several months.

Extraction, odour and the flue route

Kitchen odour is the issue that refuses more takeaway applications than any other, and with residential accommodation directly above it was the centre of the case.

The proposed system ran a stainless steel duct from a canopy over the cooking line, through the rear of the unit, and up the rear elevation to terminate above the ridge of the building. Odour control was a three stage arrangement of grease filters, an electrostatic precipitator and a carbon filter, sized for the cooking line and the hours proposed.

The Ventilation and Extraction Statement set out the cooking processes, the extract volume, the duct route and dimensions, the discharge velocity and height, the odour control specification, and the maintenance regime. It also included a risk assessment of the odour level against the sensitivity of the receptors, which in this case were the flat windows a few metres from the duct.

Three things made it work. The duct terminated above the ridge rather than at eaves level. The discharge was vertical and unimpeded rather than through a cowl that would have deflected it back down the roof slope. And the applicant offered a condition requiring filter replacement at stated intervals with records kept on site. Where cooking processes are high odour, a separate Odour Assessment may be expected, and environmental health will say so at pre-application if asked.

The duct on the rear elevation also needed its own consideration as an external alteration, with the visual effect addressed in the planning statement.

Noise from plant and from customers

Two different noise sources, assessed differently.

Plant noise, meaning the extract fan and any refrigeration or air conditioning, was assessed against background sound levels using the BS 4142 method, with measurements taken at the nearest residential facade over a period covering the proposed operating hours. The Noise Impact Assessment recommended an attenuator on the duct and anti-vibration mounts for the fan, with a rated level below background.

Customer and delivery noise is not a BS 4142 matter and was handled through the planning statement and the conditions offered: a limit on opening hours, a restriction on delivery rider waiting inside rather than on the footway, and a litter management arrangement.

Councils take late night noise from takeaway customers seriously where flats sit above, and the honest position is that this is managed by hours rather than by engineering.

Parking and servicing evidence

The highway authority's concern was short stay parking for collections and the effect of delivery mopeds on the parade.

The submission included a survey of existing on-street parking occupancy across the proposed operating hours, a note on the servicing arrangement through the rear lane with a delivery schedule outside peak times, and a proposed cycle and moped parking area in the rear yard. A full Transport Assessment was not needed at this scale, and the highway officer confirmed that at pre-application.

The parade already contained a fish and chip shop, so the authority also considered the cumulative effect of a second hot food use on parking, litter and late night activity. Cumulative impact policies exist in many local plans and are easy to overlook.

Hours and the conditions offered

Offering conditions rather than waiting to have them imposed is the tactic that most improves a takeaway application.

The applicant proposed opening from 11:00 to 22:30 Sunday to Thursday and to 23:00 on Friday and Saturday, extraction plant to be installed and maintained in accordance with the approved specification, filter servicing records to be retained, no amplified music, refuse storage within the rear yard with a stated collection frequency, and no deliveries to the premises before 08:00.

The approval came with those, plus a restriction preventing the premises operating as a drinking establishment, and a condition limiting the use to the specific sui generis hot food takeaway use rather than any sui generis use. That last condition is normal and worth expecting.

Where an existing business is seeking to extend its hours after complaints rather than open new, the evidence runs differently, as a cafe extending its hours shows.

The submitted documents

The pack, as validated:

• Application forms and ownership certificates.
• Site location plan and block plan showing the flue route.
• Existing and proposed floor plans and rear elevation showing the duct.
• A planning statement covering the use class position, local plan policy including any hot food takeaway and town centre frontage policies, and the cumulative impact point.
• The ventilation and extraction statement with the odour control specification.
• The noise impact assessment.
• A parking and servicing note with the occupancy survey.
• A refuse and litter management statement.

Validation took eight days. Environmental health asked one question about filter maintenance, which the offered condition answered. For a different route out of a retail unit, a residential conversion under Class MA follows a different procedure entirely, set out in shop to residential conversion under Class MA.
