A clean and well-maintained kitchen exhaust system is essential for the safety, hygiene, and efficiency of any commercial kitchen. Grease, smoke, and particulates from cooking can accumulate over time, leading to a hazardous environment and increased risk of fires. To prevent such problems, it’s crucial to hire a reliable kitchen exhaust cleaning contractor. In this comprehensive guide, we’ll explore the factors to consider when choosing the right contractor for your needs, ensuring quality, safety, and compliance.

Australian Standards and Compliance

When selecting a kitchen exhaust cleaning contractor in Australia, make sure they comply with Australian Standards AS 1851 and AS 1668. These standards outline the requirements for routine servicing of fire protection systems and equipment, including kitchen exhaust systems. Hiring a contractor who adheres to these standards ensures that your kitchen exhaust system is properly cleaned and maintained according to Australian regulations.

Experience and Expertise

Consider the contractor’s experience and expertise in the Australian market. A well-established company with a proven track record in the industry is more likely to deliver quality work and customer satisfaction. Check for client testimonials, online reviews, and case studies to assess their reputation and expertise.

Insurance and Licensing

Confirm that the contractor has the necessary insurance coverage and licences. A reputable kitchen exhaust cleaning company should have public liability insurance, workers’ compensation, and the appropriate state or territory licences to operate. This protects both you and the contractor in the event of accidents or damages during the cleaning process.

Comprehensive Service Offerings

A reliable kitchen exhaust cleaning contractor should provide a range of services, including thorough cleaning of the entire exhaust system (hood, filters, ductwork, and fan), detailed inspection and reporting, and regular maintenance services. This protects both you and the contractor in case of accidents or damages during the cleaning process.

Customised Solutions

Every commercial kitchen has unique needs, so it’s essential to choose a contractor who can provide customised solutions tailored to your specific requirements. Discuss your expectations, schedule, and budget with potential contractors, and ensure they are willing to adapt their services to meet your needs.

Proper Documentation

A professional contractor should provide proper documentation after completing the cleaning, including before-and-after photos, detailed inspection reports, and proof of compliance with Australian Standards AS 1851 and AS 1668. This is crucial for demonstrating compliance to local authorities and insurance providers.

Clear Communication and Customer Support

Effective communication and customer support are essential when working with a contractor. Choose a company that is responsive, transparent, and easy to communicate with, from the initial consultation to the completion of the project. This helps ensure a smooth and satisfactory experience.


Selecting the right kitchen exhaust cleaning contractor is crucial for maintaining a safe, clean, and efficient commercial kitchen in Australia. By considering factors such as Australian Standards compliance, experience, insurance, service offerings, customisation, documentation, and communication, you can find a reliable and professional contractor to meet your needs.


The kitchen exhaust system is an essential component of your restaurant, responsible for removing grease, smoke, and odours from the cooking area. Keeping this system clean not only ensures a healthy and safe environment but also maintains its efficiency and prolongs its lifespan. In this article, we will discuss the importance of cleaning your kitchen exhaust system, how often it should be cleaned, and tips for maintaining it.

Factors Affecting Cleaning Frequency

Several factors influence the required cleaning frequency of a kitchen exhaust system, including:

  • Type of cuisine: Cooking methods and ingredients used in your kitchen significantly impact grease accumulation. For example, establishments that frequently use deep-frying or wok cooking may require more frequent cleaning.
  • Volume of cooking: The more you cook, the faster grease and particulates accumulate in the exhaust system. High-volume kitchens may need more frequent cleaning than those with lower cooking volumes.
  • Local regulations: Some areas have specific regulations regarding the cleaning frequency of commercial kitchen exhaust systems. Always check and adhere to local requirements.

Cleaning Frequency Guidelines

The Australian Standards AS 1851 and AS 1668 provide guidelines for the cleaning frequency of kitchen exhaust systems in commercial kitchens:

  • High-volume cooking operations (e.g., 24-hour restaurants, char grilling, or wok cooking): minimum every 3 months
  • Moderate-volume cooking operations (e.g., fast-food restaurants, cafeterias): minimum every 6 months
  • Low-volume cooking operations (e.g., churches, day camps, seasonal businesses): every 12 months

Remember that these are general guidelines, and your specific situation may necessitate more frequent cleaning.

Regular Inspections and Maintenance

In addition to following the recommended cleaning frequency, it’s crucial to perform regular inspections and maintenance on your kitchen exhaust system. This includes checking the hood, filters, ductwork, and fan for grease buildup, wear and tear, or damage. By addressing issues promptly, you can ensure that your exhaust system remains efficient and safe between cleanings.

Choosing a Professional Cleaning Contractor

Hiring a professional kitchen exhaust cleaning contractor is essential for thorough and effective cleaning. Look for contractors with industry certifications and experience in the Australian market. Additionally, consider their insurance coverage and service offerings to ensure you choose a reliable and knowledgeable contractor.  


Maintaining a clean kitchen exhaust system for commercial kitchens is crucial to ensuring a safe and healthy working environment. Regular cleaning not only helps prevent fire hazards and promote better air quality but also ensures compliance with local health and safety regulations. Depending on the volume and type of cooking, the cleaning frequency may vary from monthly to every six months. While some aspects of cleaning can be performed in-house, it is advisable to hire professional services for thorough cleaning, especially for the ductwork. By staying proactive and adhering to the recommended cleaning schedules, you can keep your kitchen exhaust system functioning efficiently and safeguard your establishment.
