Outline for an odour management plan for a takeaway

An odour management plan for a takeaway is the document that keeps the extraction system working after the planning officer has stopped looking. It is not the extract design calculation, and it is not an odour assessment. It records what is cooked, what the abatement is, who maintains it, how often, and what happens when a neighbour complains. Councils increasingly condition one on hot food consents, and environmental health officers read the maintenance schedule first, because a correctly specified carbon filter that nobody has changed in three years is the most common cause of an odour complaint on a system that passed at the design stage.

Describing the cooking processes and risk level

Start with the cooking, in detail, because everything downstream follows from it. List the appliances, the fuel, the hours, and the processes: deep frying, chargrilling, tandoor, wok cooking, baking, griddling. Then the throughput in covers or portions, and the menu types that drive odour, particularly fish, strongly spiced dishes and chargrilled meat.

The recognised approach, in the Defra and EMAQ guidance on controlling odour and noise from commercial kitchen exhaust systems, scores the sensitivity of the surrounding receptors against the odour potential of the cooking, and produces a required level of abatement from that combination. A ground floor unit in a parade with flats above is a high sensitivity location. An isolated unit on an industrial estate is not.

State the risk category the plan is written against, and state which version of the guidance was used. Officers compare the plan to the assessment that supported the application, and a plan written against a lower risk category than the assessment assumed is the first thing they notice.

The extract system and abatement stages

Describe the system as installed, stage by stage, with the make and model of each component. A typical sequence for a high risk use runs: grease filtration at the canopy, then an electrostatic precipitator, then activated carbon, with the fan and attenuation after the abatement.

For each stage the plan should record what it removes, the airflow it was designed for, and the manufacturer's stated service interval. Bare mesh filters at the canopy with nothing downstream are not abatement, and a plan that lists only a canopy filter for a chargrill will be rejected.

Where the system differs from the approved details, say so and explain why. A Ventilation/Extraction Statement submitted with the application sets the baseline, and any departure from it needs to be reconciled before it turns into a condition compliance problem.

Discharge location and efflux velocity

Discharge is where most retrofits fail, because it is the hardest thing to change later. The guidance expects termination at roof level, discharging vertically upward, at least a metre above the ridge or the eaves of the building and of adjacent buildings, well away from any openable window, balcony or air intake.

Efflux velocity matters as much as height. A plume leaving at a high velocity, commonly specified in the range of 10 to 15 metres per second, disperses. A low velocity discharge at the same height rolls down the roof slope and collects.

Record the actual discharge height above the ridge, the terminal type, the design velocity and the distances to the nearest windows and intakes, with a dimensioned elevation. Then record the measured velocity at commissioning, because the two are often not the same.

Maintenance schedule and record keeping

This is the part the plan exists for. Give it a table with an interval against every component:

Two rules make the log credible. Every entry is dated and signed by the person who did the work, not by the manager afterwards. And carbon replacement is driven by cooking hours rather than by the calendar, with the running hours recorded, because a unit open 90 hours a week exhausts a filter far faster than one open 40.

Keep the records on the premises for inspection, and keep them for at least the period the condition specifies. Where no period is specified, three years is a reasonable default.

Staff responsibilities and training

Name the roles, not individuals, so the plan survives staff turnover. A responsible person with overall accountability, usually the manager or licensee. A named deputy. The contractor engaged for ductwork cleaning and for abatement servicing, with contact details held on site.

Training content should be short and specific: do not prop open the rear door during cooking, do not run the extract on a reduced setting to save energy, report any change in noise or smell from the plant, do not remove or bypass filters. Record the training with dates and the names of those trained.

Complaints procedure and response times

A complaints section that promises to "investigate promptly" is worthless. Commit to specific steps and specific hours.

1. Log the complaint on receipt, with date, time, weather, wind direction and what was being cooked.
2. Acknowledge to the complainant within one working day, giving a named contact.
3. Inspect the system within two working days, checking filters, carbon condition, fan operation and door discipline, and record the findings.
4. Carry out any remedial work and record it, with the date it was completed.
5. Report back to the complainant and to the environmental health officer where they raised it.
6. Review whether the maintenance interval that allowed the problem to arise needs shortening, and amend the schedule if it does.

Odour from trade premises is also a statutory nuisance category under Part III of the Environmental Protection Act 1990, so a council can act on it regardless of planning compliance. A documented complaints procedure that was followed is the strongest answer to an abatement notice.

Monitoring and review triggers

Set out when the plan itself gets revisited rather than leaving it to drift. Sensible triggers are a change of menu or cooking method, an increase in opening hours, any alteration to the extract or abatement, a change of operator, a substantiated complaint, and an annual review in any event.

Include the commissioning and annual airflow readings as an appendix, so a reviewer can see whether performance has drifted from the design.

Securing the plan through condition

Conditions on hot food consents usually come in a pair: one requiring the extraction and abatement to be installed in accordance with approved details before the use starts, and one requiring it to be maintained and operated in accordance with an approved odour management plan.

Read the wording before you submit. If the condition requires approval of the plan before the use starts, trading before approval is a breach. If the condition is drafted around a system you are no longer installing, the route is an application to vary it rather than a plan that quietly describes something else, and our note on what to submit with a section 73 application covers that submission.

PlanScope produces an Odour Assessment and a Ventilation/Extraction Statement among its 66 report types, and councils usually expect a suitably qualified author for odour work, so professional review is strongly advised. The management plan itself is a separate operational document, normally written with the installer and the servicing contractor rather than generated as a report. Browse the categories in all 66 report types to see which of the application documents apply, and the Odour Assessment page sets out what that assessment covers.

This is general guidance, not legal advice; check the position with your local planning authority or environmental health team before relying on it. For specialist technical reports, qualified professional input may be required. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission.
