Ductwork and Ventilation Services for Food Production Facilities

Food production facilities face air-quality, hygiene and fire-safety demands that few other buildings share. Clean Ducts provides full ductwork cleaning, kitchen-extract servicing, mechanical ventilation and fire-damper compliance built around the realities of production environments.

Clean Ducts works with food producers, manufacturers and their FM providers across London and the Home Counties. Good ventilation and duct cleaning are not optional extras. They are foundations for hygiene, safety and compliance, and where a facility has not been professionally cleaned and inspected in the past 12 to 18 months, both the business and its staff carry avoidable risk. Annual inspection is the minimum safe standard.

Why the food-production sector is different

Food production facilities combine heavy usage, high heat loads, abundant moisture and grease-laden air. Whether you run bakery lines in Slough, snack-packaging in Milton Keynes or meat-processing in Essex, that mix puts pressure on every part of your air-handling and extraction system.

Typical pressure points include:

• Kitchen and process extract canopies pull significant grease, vapour and heat. As deposits build up in the ductwork, airflow drops and fire risk rises
• Air handling units (AHUs) must deliver clean supply air and manage humidity, particularly across chilled and ambient zones
• Fire dampers in ductwork that crosses compartment walls must operate reliably, often in older buildings where access is limited

Clean Ducts has more than ten years of experience working with food-production clients across London, the Home Counties and neighbouring large towns. We know the typical pain points and how to resolve them without stopping your lines longer than necessary.

Our services for food production clients

1. Ductwork cleaning and maintenance

Commercial and industrial air-duct cleaning covers full systems, production-line ventilation and chilled and ambient storage zones, with ancillary office and staff areas handled where required. Cleaning is carried out to BESA TR19, the industry standard for ventilation hygiene, and includes:

• Camera inspections and smoke testing to verify duct integrity and cleanliness
• Condition scoring recorded for your compliance file
• Access panel installation where the system cannot otherwise be reached

A cleaned duct system improves airflow, reduces energy use and lowers fire risk.

2. Kitchen extract systems

High-output food production loads extract systems with grease far faster than a standard kitchen. Cleaning follows TR19 Grease, the standard for kitchen-extract fire-risk management, and covers:

• Full extract duct cleaning from canopy to discharge
• Canopy, fan and filter cleaning, including drive units and bearings
• Grease-trap servicing and post-clean verification against measured grease thickness

A poorly maintained extract system can fail airflow specification, breach hygiene standards and create insurance problems. Heavy production usually calls for cleaning every three to six months.

3. Mechanical air ventilation

Installation, repair and maintenance of ventilation systems, including AHUs, keeps supply and extract air balanced across the facility. Services include:

• Ventilation surveys and inspections covering air-change rates, pressure differential and humidity control
• Validation of supply, extract and balance, with remediation where needed
• Commissioning and balancing to meet design specification and hygiene demands

Balanced ventilation delivers consistent conditions for production, staff comfort and regulatory compliance.

4. Fire safety and compliance

Fire dampers in ductwork that passes through fire-compartment walls or ceilings must function on demand. Testing and inspection are carried out in line with BS 9999, alongside TR19-aligned duct-cleaning processes, and include:

• Fire-damper testing and inspection to BS 9999
• Documentation and certification for fire-risk assessment and insurance audit readiness
• Full photographic evidence for each tested damper

Where ductwork crosses fire compartments, dampers should be tested at least every 6 to 12 months.

5. Specialist clean-room services

Some facilities run production in clean-room or controlled-environment zones, for example allergen-controlled lines, pharmaceutical-food blends or speciality packaging. Services include:

• Commissioning and validation of clean-room ventilation
• Supply-air filtration and positive-pressure system checks
• Documentation to the higher control standards these zones demand

Controlled-environment zones require tighter filtration, monitoring and record-keeping than standard production areas.

Why food producers choose Clean Ducts

• More than ten years of service in food-production environments where downtime and hygiene risk are tightly constrained
• BESCA Vent Hygiene Associate membership, so ventilation-hygiene work is assessed against recognised standards
• Clear documentation suitable for hygiene audits, fire-risk assessments and insurance reviews
• Flexible scheduling that works around production windows to avoid disruption
• Maintenance plans tailored to your usage rather than a fixed template
• Regional coverage across London, the Home Counties and major centres including Reading, Slough, Watford, Harlow, Milton Keynes and Basildon

Legal and industry obligations for food production facilities

Your facility must meet several regulatory and industry standards. Key obligations include:

• Retained Regulation (EC) No 852/2004, Annex II, Chapter I, which requires food premises to have suitable and sufficient natural or mechanical ventilation, with systems that allow cleaning and filter access
• The Workplace (Health, Safety and Welfare) Regulations 1992, Regulation 6, which requires employers to ensure ventilation is adequate in enclosed workspaces
• Health and Safety Executive guidance on managing fumes and excess heat, so that air movement supports a safe working environment
• Fire-safety duties that depend on maintained ductwork, functioning fire dampers and current inspection records

Failure to comply can lead to hygiene audit failures, fire-risk issues, insurance claim problems, staff health concerns and enforcement action.

Quick-start checklist for your facility

• Inspect ductwork via camera and smoke test at least annually
• Schedule full kitchen-extract cleaning in line with usage, with heavy production typically every three to six months
• Test and certify fire dampers every 6 to 12 months where ductwork crosses fire compartments
• Review AHU filters monthly and act on any drop in airflow
• Commission and balance ventilation systems after any change to layout or output
• Record every inspection and clean in your maintenance system

Common questions

How often should a food production facility be cleaned? Ductwork should be inspected at least annually. High-output extract systems usually need cleaning every three to six months, depending on hours of operation.

Can work be scheduled around production? Yes. Work is planned around your production windows, including out-of-hours, to keep disruption to a minimum.

Are reports suitable for hygiene audits and insurance? Yes. Every job includes clear, photo-supported documentation aligned to the relevant standard.

Do you cover controlled-environment and clean-room zones? Yes. We commission and validate clean-room ventilation, filtration and positive-pressure systems where facilities require them.

Book a ventilation survey

A documented survey shows exactly where your ductwork, extract systems and fire dampers stand against current standards. Request a survey for your food production facility to get a clear, evidence-backed baseline for the building.
