The Problem

Kitchen odour can quickly become a planning, compliance and neighbour issue

Commercial kitchen odour is one of the most common reasons restaurants, takeaways, dark kitchens and food premises face objections, complaints or requests for additional information from Environmental Health or local planning authorities.

Grease, smoke, cooking vapours and odour compounds can travel through the extract duct and discharge close to nearby homes, offices or public areas. The right kitchen extract odour control system should be selected based on the cooking type, airflow rate, duct layout, discharge position and proximity of sensitive receptors.

Ozcon supports commercial kitchens where odour mitigation is required for a new planning application, an extract upgrade, a restaurant refurbishment or an existing nuisance complaint.

Commercial kitchen extract and ventilation maintenance

Extract system conditions matter Odour performance depends on airflow, grease control, duct layout and correct maintenance.

When You Need Help

Help with kitchen odour complaints, planning comments and restaurant extract upgrades

Most enquiries start with a practical problem rather than a product name. We help contractors, operators and consultants select a suitable odour control approach for the actual kitchen extract arrangement.

Environmental Health odour complaint

If Environmental Health has raised a concern about restaurant, takeaway or commercial kitchen smells, we can review the extract system details and advise on suitable odour control equipment.

Planning application odour control

For new food premises, change-of-use applications or kitchen refurbishments, odour mitigation may need to be considered alongside airflow, discharge height and nearby sensitive receptors.

Existing kitchen extract upgrade

Existing kitchen ventilation systems can often be upgraded with UV ozone or controlled ozone treatment where space, duct layout and maintenance access allow.

Smoke, Grease and Odour

Odour control works best when the extract system is properly filtered first

UV ozone and controlled ozone systems are designed to target residual cooking odours in the extract duct. However, heavy grease, smoke and fine particulate can reduce performance if they are not controlled before the odour control stage.

For smoke-heavy cooking, solid-fuel cooking or visible discharge problems, an electrostatic precipitator may be required before the odour control system.

Grease filtration at canopy or extract level
ESP filtration for smoke, grease aerosol and fine particulate where required
UV ozone or controlled ozone treatment for residual odour
Correct residence time, duct layout and safe discharge arrangement
Planned cleaning, lamp replacement and maintenance access

Controlled Ozone Option

Controlled ozone odour control for larger kitchen extract systems

For larger, variable or more demanding commercial kitchen extract systems, a controlled ozone injection system may be more suitable than a compact UV/ozone unit. The CVS system is designed for higher airflow ranges, stronger odour loads and applications requiring more flexible ozone control.

Controlled Ozone System

CVS Controlled Ozone System

Typical extract airflow range Approx. 0.9 to 7.2 m³/s

The CVS system can be considered where higher airflow, stronger odour loading or more flexible control is required. It is suitable for commercial kitchen extract systems where the odour risk, discharge location or local authority requirements call for a more controlled approach.

We can advise whether the CVS system or the Xtract range is more appropriate once the extract airflow, duct layout and cooking process are known.

Xtract Range

UV ozone odour control for restaurants, takeaways and commercial kitchens

The Xtract range provides practical UV/ozone odour control options for restaurants, takeaways, dark kitchens and smaller to medium commercial kitchen extract systems. The correct model depends on extract airflow, cooking intensity, duct layout, grease filtration and odour risk.

Compact Retrofit

Xtract 2100

Recommended extract airflow Up to 1.5 m³/s

A compact UV/ozone odour control option for restaurants, takeaways and smaller commercial kitchen extract systems where space is limited and a practical retrofit solution is required.

Increased Capacity

Xtract 2100 Plus

Recommended extract airflow Up to 2.0 m³/s

A higher-output version of the Xtract 2100, suitable for medium-sized commercial kitchen extract systems requiring additional odour treatment capacity while keeping the system compact.

Higher Capacity

Xtract 4200

Recommended extract airflow Up to 3.0 m³/s

A higher-capacity UV/ozone odour control system for larger kitchens, stronger odour loads or extract systems requiring greater treatment capacity.

Site Dependent

Every kitchen extract system is different

Correct selection depends on airflow, cooking load, duct layout, discharge location and available access for maintenance.

Applications

Suitable for restaurants, takeaways, dark kitchens and commercial food premises

Our commercial kitchen odour control systems can be considered for both new extract projects and retrofit upgrades where odour reduction is required. Applications include restaurant extraction, takeaway ventilation, hotel kitchens, food courts, bakeries and commercial catering sites.

Supporting planning and Environmental Health requirements

Local authorities may request evidence that a commercial kitchen extract system has suitable odour control, especially where the discharge is close to residential receptors, offices, flats, public spaces or other sensitive locations.

While each site must be assessed individually, odour control selection is often considered alongside recognised industry guidance such as DW/172, EMAQ guidance and historical DEFRA kitchen extract guidance.

We can help you prepare clear product information and practical system guidance for contractors, consultants, landlords, planning officers or Environmental Health teams.

Kitchen extract odour control maintenance and service access

Maintenance keeps performance consistent Correct cleaning, access and servicing are essential for long-term odour control.

Aftercare

Maintenance matters for long-term odour control performance

Commercial kitchen odour control systems must be kept clean and serviced correctly to remain effective. UV lamps, filters and internal components may require periodic replacement depending on operating hours, grease loading and site conditions.

Ozcon can provide equipment guidance, spare parts and maintenance advice. Where required, servicing can be coordinated with suitable specialist contractors.

Important: Odour control performance depends on correct system selection, suitable installation, sufficient contact time, proper grease filtration and ongoing maintenance.

FAQ

Commercial kitchen odour control questions

Common questions from restaurant operators, takeaway owners, ventilation contractors and consultants.

Do commercial kitchens need odour control?

Not every kitchen needs a dedicated odour control system, but it is commonly required where cooking odours may affect nearby residents, offices or public areas, or where Environmental Health or planning officers request odour mitigation details.

What is the best odour control system for a restaurant kitchen?

The best system depends on the cooking type, extract airflow, grease and smoke load, duct layout, discharge position and proximity of sensitive receptors. Smaller systems may suit compact UV ozone units, while larger or more demanding systems may need controlled ozone injection.

Can ozone be used for kitchen extract odour control?

Yes, ozone can be used to oxidise residual odour compounds in suitable kitchen extract ductwork. It must be correctly selected, installed and maintained, with enough duct contact time and appropriate safety consideration.

Is UV ozone suitable for takeaway extract systems?

UV ozone systems can be suitable for many takeaway and restaurant extract applications, depending on airflow, cooking intensity, duct access and odour risk. High-grease or smoke-heavy applications may also require improved filtration before the odour control stage.

Do I need ESP filtration as well as odour control?

ESP filtration may be required where there is visible smoke, grease aerosol or fine particulate in the extract air. In those cases, ESP filtration can reduce the load before UV ozone or controlled ozone odour treatment.

What information is needed to size a kitchen odour control system?

Useful information includes the cooking process, extract airflow rate, duct dimensions, fan location, discharge position, nearby receptors, photos of the ductwork and any comments from Environmental Health or planning.
