Which reports a shop to hot food takeaway change needs

A hot food takeaway is sui generis, so there is no permitted development route from a shop. The takeaway change of use documents that decide these applications are the extraction drawing, the odour assessment and the noise report on the plant, and an application without all three is usually invalid before anyone reaches the merits.

Shops sit in Class E(a). Restaurants and cafes sit in Class E(b), and movement within Class E needs no permission. The sale of hot food principally for consumption off the premises was taken out of the classes altogether when the order was amended in 2020, which is why the takeaway sits outside the system and needs a full application.

Why a takeaway is sui generis and what that means

Sui generis means the use is in a class of its own. A change to it is a material change of use requiring planning permission, and a change from it is equally controlled, which matters when a takeaway operator later wants to flip to a restaurant.

The practical consequences are three. There is no prior approval route and no permitted development fallback. The application is a full application with a fee based on the floorspace. And the council can impose conditions on hours, extraction, deliveries and refuse that it could never impose on a movement within Class E.

Mixed operations muddy this. A cafe that also does takeaway trade is judged on the primary use, and where the takeaway element becomes the dominant activity the use has changed. Applicants who describe the proposal loosely end up with a permission that does not cover what they actually do. The gym in a Class E industrial unit piece deals with the mirror image of this problem, where a use that looks like it fits Class E does not.

Extraction and odour evidence the council expects

This is the document that sinks most applications.

The council wants a scheme drawing showing the full extraction system: the canopy over the cooking line, grease filters, the duct route through the building, the fan, any odour abatement, the attenuator and the discharge point. The discharge point matters more than anything else. A duct terminating at first floor level next to a residential window will be refused however good the filtration is.

The recognised approach is an odour risk assessment that scores the sensitivity of the receptors around the site against the type of cooking proposed, and then specifies an abatement level to match. Deep frying and chargrilling sit at the high end. A sandwich bar with a panini press does not.

Abatement options run from basic grease filtration up to electrostatic precipitators, carbon filtration and ultraviolet systems, and the specification has to be matched to the risk score rather than chosen by price. A Ventilation and Extraction Statement sets out the system, and an Odour Assessment does the risk scoring where the receptors are close or the cooking is aggressive.

Where the building has flats above, the duct route becomes a landlord and lease problem as well as a planning one, and the point at which to find that out is before the application. The guide to reports for flats above shops in a mixed use scheme covers the residential side of the same building.

Noise from plant and from customers

Two different noise sources, assessed differently.

Plant noise, meaning the extract fan, any refrigeration and air conditioning, is assessed against the British Standard method for rating industrial and commercial sound affecting residential receptors. That gives a rating level compared with the background sound level, with corrections for tonal, impulsive or intermittent character. The assessment needs a background survey at the times the plant will run, which for a takeaway means late evening rather than the middle of the afternoon.

Customer noise is not covered by that standard and is assessed qualitatively: door opening and closing, conversation on the pavement, car doors, engines idling while people wait. Councils deal with it through hours conditions and, occasionally, through a management plan.

A Noise Impact Assessment covering both, with the survey times stated and the plant specification appended, is what an environmental health officer wants to see. Getting the survey done at the wrong time of day is the most common reason for a request for further information.

Parking, servicing and refuse storage

Takeaways generate short duration parking demand concentrated in the evening peak, and delivery riders concentrate it further.

Set out where customers will stop, whether there are loading restrictions, and where delivery riders will wait. A rank of mopeds on a residential street is a live objection topic and it is better answered in the application than at committee.

Servicing needs a stated delivery window and a vehicle type. Refuse needs a store sized for the waste stream, which for a takeaway includes a lot of packaging and used cooking oil, with a collection contract. A Waste Management Strategy covering storage volumes, collection frequency and the route from store to kerb answers the question properly.

Opening hours and how they are conditioned

Hours are the most heavily negotiated condition on any takeaway permission.

Expect a condition limiting opening to stated times, often with earlier closing on Sundays, and sometimes a separate restriction on deliveries and on the operation of the extraction plant. Where the premises also needs a licence for late night refreshment, the licensing and planning hours can differ, and the more restrictive one governs.

If the business case depends on trading past midnight, say so at the outset and evidence it. Applying for shorter hours to get a permission and then applying to vary it later is a recognised tactic and officers recognise it too.

Health policy restrictions near schools

Many local plans carry a policy restricting new hot food takeaways within a stated distance of a school, or in wards with high levels of childhood obesity, and some set a cap on the proportion of takeaway units in a parade.

These policies are local and the distances and criteria vary, so read the adopted plan before you buy the lease. Where such a policy applies, the application needs to address it directly with catchment mapping and, if the case is arguable, evidence on the existing mix of uses.

The arguments that sometimes succeed are that the unit is outside the stated catchment when measured by walking route rather than as the crow flies, that the parade already has a mix which the proposal does not tip, or that the operating hours exclude the period when children travel to and from school. Each of those is an evidence exercise rather than an assertion, and each needs a drawing.

What does not work is arguing that the policy is unreasonable. It is in the adopted plan, and the decision has to be made in accordance with it unless material considerations indicate otherwise.

The document pack for a small unit

For a single unit change of use from a shop to a takeaway, expect to submit:

• Application form and fee, with the correct description of development naming the sui generis use
• Location plan and existing and proposed floor plans and elevations
• A Planning Statement addressing the use class position, the local plan policies and the health policy where it applies
• A ventilation and extraction scheme drawing with a duct route and termination detail
• An odour risk assessment where receptors are close or the cooking is high risk
• A noise assessment of the proposed plant with a background survey
• A refuse and servicing statement
• A shopfront drawing where the frontage changes, and a separate advertisement consent application for the signage

Commission the extraction design before anything else. Every other document depends on where that duct can go, and on many terraced high street units the honest answer is that it cannot go anywhere acceptable.
