Dirty air ducts are more than an inconvenience – they’re a health and safety risk and a legal liability.

Over time, dust, debris, and contaminants accumulate in your ventilation system. In commercial kitchens, grease deposits build up in extract ductwork. Left uncleaned, these create serious problems:

Fire Risk

Around 70% of commercial kitchen fires originate in extract ventilation systems due to grease build-up. Regular ductwork cleaning significantly reduces this risk.

Poor Indoor Air Quality

Contaminated ductwork circulates dust, allergens, and pollutants throughout your building. This affects staff health, productivity, and wellbeing. Clean air ducts mean better indoor air quality for everyone.

Legal Liability

Under the Health and Safety at Work Act, employers must provide a safe working environment – including clean air. Failing to maintain your ventilation system can expose you to legal action.

Insurance Issues

Many insurers require evidence of regular, compliant duct cleaning. Without it, you risk invalidating your cover. If a fire occurs and your ductwork hasn’t been properly maintained, your claim could be denied.

TR19 is the industry standard for ventilation hygiene, published by the Building Engineering Services Association (BESA). It specifies how ductwork must be regularly cleaned, inspected, and documented.

TR19 compliance isn’t just best practice – it’s how you demonstrate you’re meeting your obligations under the Health and Safety at Work Act and Regulatory Reform (Fire Safety) Order.

What TR19 Compliance Means

• Pre-clean inspection with photographic evidence
• Cleaning to BESA TR19 guidelines using specialist equipment
• Post-clean verification and documentation
• Certificate of compliance for your records
• Recommendations for future cleaning frequency

TR19 vs TR19 Grease

BESA TR19 covers general ventilation systems – offices, healthcare facilities, schools, and commercial buildings. TR19 Grease (the grease specification) applies specifically to commercial kitchen extraction systems where grease build-up poses a fire hazard.

We provide both TR19 and TR19 Grease compliant cleaning services.

We clean all types of commercial ventilation systems and ductwork, including:

HVAC Systems

Complete cleaning of heating, ventilation, and air conditioning ductwork. We clean supply and return air ducts, ensuring your HVAC system operates efficiently and circulates clean air throughout your building.

Air Handling Units

Cleaning of air handling units (AHUs), including filters, coils, and internal components. Regular cleaning maintains air quality and system efficiency.

Ventilation Ductwork

From office ventilation to industrial air supply systems, we clean ventilation ductwork of all sizes and configurations. Our teams have access to specialist equipment for complex installations.

Air Conditioning Systems

Ductwork cleaning for air conditioning systems, helping maintain cooling efficiency and indoor air quality.

Our duct cleaning services help extend the life of your HVAC equipment, reduce energy consumption, and maintain a healthy environment for building occupants.

Commercial kitchen extract systems require specialist attention. Grease accumulates rapidly in kitchen ductwork, creating a significant fire risk that demands regular professional cleaning.

What We Clean

• Kitchen extract ductwork and canopies
• Grease filters and baffle systems
• Extract fans and motors
• Kitchen ventilation systems
• Rooftop extract units

TR19 Grease Compliance

Commercial kitchens are subject to TR19 Grease specifications, which mandate more frequent cleaning than standard ventilation systems. Depending on usage:

• Heavy use kitchens (12+ hours/day): Every 3 months
• Moderate use (6-12 hours/day): Every 6 months
• Light use (2-6 hours/day): Every 12 months

We provide TR19 Grease compliant kitchen extraction cleaning with full documentation for your insurance and compliance records.

We follow a systematic process to ensure thorough, compliant duct cleaning:

1. Initial Survey

We assess your ductwork system, identify access points, and determine the scope of work. This includes a duct inspection using cameras where necessary.

2. Access for Cleaning

Where needed, we install access panels to reach all areas of your ductwork. These remain in place for future maintenance and inspection.

3. Deep Cleaning

Using specialist equipment including rotary brushes, HEPA-filtered vacuum systems, and compressed air tools, we remove all deposits from your ductwork. For kitchen extract systems, we use appropriate degreasing methods.

4. Verification

Post-clean inspection verifies the work meets TR19 standards. We photograph the cleaned ductwork and document our findings.

5. Certification

You receive a certificate of compliance, photographic evidence, and recommendations for your ongoing cleaning and maintenance schedule.

We provide duct and ventilation cleaning services to commercial and industrial clients throughout the South of England, from Birmingham southwards.

How often should ducts be cleaned?

It depends on your environment. Office ventilation typically needs cleaning every 1-2 years. Commercial kitchen extract systems need cleaning every 3-12 months depending on usage intensity. We’ll assess your system and recommend an appropriate schedule.

Why is duct cleaning important?

Regular duct cleaning protects indoor air quality, reduces fire risk (especially in kitchens), ensures compliance with health and safety regulations, and can extend the life of your HVAC equipment. It’s also often required by insurers.

What is TR19?

TR19 is the BESA (Building Engineering Services Association) specification for ventilation hygiene. It sets the industry standard for how ductwork must be regularly cleaned and maintained. TR19 compliance demonstrates you’re meeting your legal obligations.

How do I know if my ducts need cleaning?

Signs include visible dust or debris around vents, reduced airflow, unusual odours, or it’s simply been over 12 months since your last clean. We can conduct an inspection to assess your ductwork condition.

Do you provide certification?

Yes. All our duct cleaning work comes with documentation including photographic evidence and a certificate of compliance. This provides the audit trail you need for insurance and regulatory purposes.
