Kitchen Extraction Cleaning

At Doctor Duct, we provide specialist kitchen extraction cleaning for restaurants, commercial kitchens, hotels, schools, and food production facilities. 

Maintaining a clean extraction system is essential for fire safety, regulatory compliance, and efficient kitchen ventilation.

Over time, grease, carbon deposits, and airborne contaminants accumulate inside canopy hoods, ductwork, fans, and filters. 

Without routine commercial kitchen extract cleaning, this build-up becomes a serious fire hazard and can compromise airflow performance.

Our trained technicians deliver thorough, compliant, and fully documented kitchen ventilation cleaning, ensuring your system operates safely and efficiently.

What Is Kitchen Extraction Cleaning?

Kitchen extraction cleaning involves the deep cleaning of the entire kitchen extract system, including canopies, grease filters, ductwork, and extraction fans.

The purpose is to remove accumulated fats, oils, grease (FOG), and carbon deposits that pose fire and hygiene risks.

Unlike surface-level cleaning, professional extract duct cleaning targets internal ductwork where grease accumulation is often hidden from view. 

Cleaning is carried out in accordance with TR19® guidelines, which outline recommended cleaning frequencies based on kitchen usage levels.

At Doctor Duct, we use specialist scraping tools, rotary brushing systems, and high-powered vacuum equipment to ensure thorough contamination removal.

Why Is Kitchen Extract Cleaning Important?

Failure to maintain regular kitchen extraction cleaning significantly increases the risk of kitchen fires. 

Grease deposits inside duct systems are highly flammable and can ignite if exposed to high temperatures or sparks.

In addition to fire risk, neglected extraction systems can result in poor airflow, excessive kitchen heat, lingering odours, and reduced air quality. 

Insurance providers often require evidence of compliant kitchen extract cleaning, and failure to maintain records can invalidate cover in the event of a fire.

Professional servicing ensures compliance with fire safety standards and protects both staff and customers.

How Much Does Kitchen Extraction Cleaning Cost?

The cost of kitchen extraction cleaning ranges from £400 to £1,500.

The cost depends on system size, duct length, access complexity, and grease accumulation levels.

Larger commercial systems or heavily contaminated ductwork in high-volume kitchens may exceed this range. 

At Duct Doctors, we provide detailed site assessments and transparent quotations before commencing any work.

How Often Should Kitchen Extraction Cleaning Be Carried Out?

The required frequency of commercial kitchen extraction cleaning depends on cooking intensity and operational hours. 

High-volume kitchens operating 12 to 16 hours per day may require cleaning every three months, while moderate-use kitchens may follow six-month intervals.

TR19® guidelines provide recommended cleaning schedules based on usage. 

Adhering to these standards ensures your kitchen ventilation cleaning remains compliant and safe.

We can establish a tailored maintenance schedule to suit your business operations.

What Is Included in Kitchen Extraction Cleaning?

Our kitchen extraction cleaning covers canopy hoods, grease filters, ductwork (horizontal and vertical runs), access panels, and extraction fans. 

We remove internal grease deposits using industry-approved equipment and ensure all accessible components are cleaned to compliant standards.

Upon completion, we provide photographic evidence and a detailed report confirming the condition of the system.

What Happens If I Don’t Schedule Kitchen Extraction Cleaning?

Failure to arrange routine kitchen extraction cleaning significantly increases fire risk within your commercial kitchen. 

Grease deposits inside ductwork and extraction fans are highly combustible. If a flare-up occurs on a cooking appliance, flames can travel rapidly through grease-lined ducts, spreading fire throughout the building.

Beyond fire risk, neglected systems can lead to reduced airflow, excessive heat in the kitchen, and strong lingering odours. 

Insurance providers often require evidence of compliant kitchen extract cleaning, and failure to maintain service records may invalidate your policy in the event of a claim.

Regular commercial kitchen extraction cleaning protects your premises, staff, and business continuity.

Is Kitchen Extraction Cleaning a Legal Requirement?

While legislation may not specify exact cleaning intervals, businesses operating commercial kitchens have a legal duty to manage fire risk under the Regulatory Reform (Fire Safety) Order 2005. 

Industry guidance such as TR19® sets recognised standards for kitchen ventilation cleaning.

Environmental health officers and fire safety inspectors may request evidence of regular extract duct cleaning. 

Failure to demonstrate compliance can result in enforcement action, fines, or even temporary closure.

Maintaining documented kitchen extraction cleaning ensures you meet both safety and insurance expectations.

How Do I Know If My Extraction System Needs Cleaning?

There are several indicators that your system may require kitchen extraction cleaning. 

Visible grease around canopy hoods, excessive smoke lingering during cooking, reduced airflow, or increased kitchen temperatures all suggest restricted ventilation.

Unusual noises from extraction fans or persistent odours may also indicate internal grease build-up. 

In many cases, contamination is not visible externally, which is why routine inspection and commercial extract cleaning are essential.

At Duct Doctors, we conduct thorough system assessments to determine contamination levels before recommending service.

How Long Does Kitchen Extraction Cleaning Take?

The duration of kitchen extraction cleaning depends on duct length, system complexity, and grease accumulation. 

Smaller systems may require several hours, while large commercial kitchens with extensive duct runs may require a full day or overnight service.

To minimise disruption, we schedule kitchen ventilation cleaning outside of trading hours whenever possible. 

Our team works efficiently while maintaining strict compliance and safety standards.

Does Kitchen Extraction Cleaning Improve Airflow?

Yes. Grease build-up restricts airflow within duct systems, forcing fans to work harder and reducing ventilation efficiency. 

Professional extract duct cleaning removes internal obstructions, restoring optimal airflow performance.

Improved airflow helps regulate kitchen temperature, reduce smoke accumulation, and maintain a safer working environment for staff. 

Efficient systems also place less strain on mechanical components, potentially extending system lifespan.

Will Kitchen Extraction Cleaning Reduce Energy Costs?

When grease restricts ductwork and fans, extraction systems consume more energy to maintain airflow. 

By carrying out routine kitchen extraction cleaning, system efficiency improves, and mechanical strain is reduced.

While energy savings vary depending on system size, improved ventilation performance often contributes to lower operational costs over time.

Do You Provide Certification After Kitchen Extraction Cleaning?

After completing commercial kitchen extraction cleaning, we provide a detailed report including before-and-after photographs and certification confirming the work completed.

This documentation supports insurance requirements, fire safety audits, and compliance inspections. 

Many businesses rely on this certification as part of their safety management system.

Can You Clean High-Level or Difficult-to-Access Ductwork?

Our technicians are trained and equipped to carry out high-level kitchen extract cleaning, including vertical duct runs and rooftop extraction systems.

We use specialist access equipment and controlled cleaning methods to ensure safe and thorough servicing of hard-to-reach areas. 

Every section of the system is inspected to ensure compliance with TR19® standards.

Do You Offer Scheduled Maintenance Plans for Kitchen Extraction Cleaning?

Doctor Duct offers tailored maintenance contracts for kitchen extraction cleaning. 

These plans ensure cleaning is carried out at recommended intervals based on kitchen usage levels.

Scheduled servicing reduces the risk of missed compliance deadlines and spreads maintenance costs predictably throughout the year. 

For busy commercial kitchens, a structured cleaning plan provides peace of mind and consistent safety.
