At Commercial Extraction Cleaning, we provide professional cleaning services for kitchen extract and ventilation systems across the UK. 

In busy commercial kitchens, grease, oil, and dust build up quickly inside canopies, filters, fans, and ductwork. If not regularly cleaned, these deposits pose a serious fire hazard, reduce system performance, and compromise hygiene. 

Our services are fully TR19® compliant, ensuring fire safety, insurance validity, and healthier working environments.

Why Is Commercial Extraction Cleaning Important?

Kitchen extraction systems handle grease and smoke every time cooking equipment is used. Over time, this creates thick deposits inside ductwork, fans, and hoods. 

These deposits are highly flammable and can cause fires to spread rapidly through the building if ignited. 

Dirty systems also reduce airflow, increase odours, and put strain on fans and motors. 

Regular cleaning eliminates these risks and ensures kitchens operate safely and efficiently.

What Does Commercial Extraction Cleaning Involve?

The process starts with a full inspection of the kitchen canopy, filters, fans, and ductwork. 

Technicians then use scrapers, degreasing chemicals, steam cleaning, and rotary brushes to remove built-up grease and carbon. 

Access panels may be installed to reach hidden areas of ducting. Once the system is fully cleaned, we issue a TR19® compliant hygiene certificate, which is required by insurers and fire safety officers.

How Often Should Commercial Extraction Systems Be Cleaned?

The frequency depends on how many hours the kitchen operates each day. Heavy-use kitchens running 12–16 hours daily should be cleaned every 3 months. 

Moderate-use kitchens operating 6–12 hours daily require cleaning every 6 months. Light-use kitchens running just 2–6 hours per day should be cleaned at least once a year. 

These intervals follow TR19® guidelines, which are the recognised industry standard across the UK.

What Are the Benefits of Commercial Extraction Cleaning?

Extraction cleaning offers significant benefits for safety, efficiency, and compliance.

Key benefits include:

• Reduces the risk of kitchen fires caused by grease build-up.
• Ensures compliance with TR19® standards and UK fire safety law.
• Maintains insurance coverage by providing valid cleaning certificates.
• Improves airflow, reducing heat and odours in the kitchen.
• Extends the life of fans, filters, and ductwork.

How Much Does Commercial Extraction Cleaning Cost?

The cost of commercial extraction cleaning is from £250 to £500, while larger kitchens, hotels, or canteens may range from £1,000 to £2,000+. 

The cost varies depending on the size of the system, contamination levels, and access. 

We provide tailored quotes following a site survey, ensuring transparency and accuracy. Investing in regular extraction cleaning is far less costly than fire damage, fines, or invalidated insurance claims.

What Legal Standards Apply to Commercial Extraction Cleaning?

In the UK, the Regulatory Reform (Fire Safety) Order 2005 requires businesses to keep kitchen extract systems clean and safe. 

Insurers and fire officers also require compliance with TR19® standards, which specify cleaning methods and intervals. 

Failure to comply may lead to enforcement action, invalidated insurance, or even closure of premises. 

A valid TR19® certificate proves compliance and protects both your business and staff.

Is Commercial Extraction Cleaning Disruptive?

We plan extraction cleaning to minimise disruption to your business. Cleaning can be scheduled overnight, at weekends, or outside service hours. 

Our technicians use specialist cleaning tools to contain grease and prevent mess in food preparation areas. 

This ensures your kitchen is safe, clean, and ready to use immediately after the service.

Do You Provide Certificates After Cleaning?

After every commercial extraction cleaning service we issue a TR19® compliant hygiene certificate. 

This document details the areas cleaned, the methods used, and includes photographic evidence where necessary. 

Certificates are vital for insurance compliance, fire safety inspections, and environmental health checks. 

Without a valid certificate, many insurers may refuse to cover fire damage linked to dirty extraction systems. 

Having these records also demonstrates your duty of care to staff and customers.

Can Extraction Cleaning Help with Kitchen Odours?

Odours in commercial kitchens often come from grease, smoke, and bacteria trapped in extraction ducts. 

If left uncleaned, these odours can spread into customer areas and even neighbouring businesses. 

During cleaning, we remove grease deposits and apply sanitising treatments where necessary. 

This eliminates smells at their source, leaving the kitchen fresher and more pleasant to work in. Improved airflow also helps prevent future odour build-up.

What Happens If I Don’t Clean My Extraction System?

Failing to clean your kitchen extraction system poses serious risks. 

Grease deposits create a high fire hazard that can cause flames to spread rapidly through ductwork. 

Non-compliance with TR19® and fire safety law may also invalidate insurance cover, leaving your business exposed financially. 

In addition, environmental health officers or fire inspectors can issue fines, enforcement notices, or even close premises until compliance is achieved. Regular cleaning prevents these risks and protects your reputation.

How Long Does Commercial Extraction Cleaning Take?

The time required depends on the size and condition of the system. 

A small restaurant system may take 4–6 hours, while larger systems in hotels or hospitals may require a full day or more. I

f grease build-up is heavy, additional time may be needed to ensure a thorough clean. 

We provide clear timelines in advance and can schedule work overnight or outside trading hours to avoid disrupting your kitchen operations.

Do You Install Access Panels for Hard-to-Reach Ducts?

Access panels are often required to ensure full cleaning of hidden sections of ductwork. Without them, grease can build up in inaccessible areas, leaving fire hazards behind. 

As part of our service, we can install access doors that meet TR19® specifications, allowing for proper cleaning and future inspections. 

This ensures every part of your extraction system is maintained to a safe, compliant standard.
