Kitchen Extract Cleaning Frequency Regular cleaning of kitchen extract and HVAC (heating, ventilation, and air conditioning) systems is essential for fire safety, compliance, air quality, and system efficiency. The frequency of cleaning depends on usage, environment, and industry standards such as TR19®. Kitchen extract systems accumulate grease quickly, making them one of the highest-risk areas for fire. According to TR19® guidelines, cleaning frequency should be based on usage levels: Heavy Use (12–16 hours per day): Every 3 months Moderate Use (6–12 hours per day): Every 6 months Light Use (2–6 hours per day): Every 12 months Low Use (less than 2 hours per day): Every 12–24 months Regular cleaning removes grease build-up and reduces the risk of fire, ensuring compliance with fire safety and insurance requirements. HVAC System Cleaning Frequency HVAC systems do not accumulate grease like kitchen extracts, but they still collect dust, debris, and contaminants that affect performance and air quality. Typical cleaning and maintenance schedules include: Air filters: Every 1–3 months Kitchen Extract Ductwork cleaning: 3, 6 or 12 months depending on usage Full system inspection: Annually Businesses with high occupancy, dust levels, or sensitive environments (such as healthcare or food production) may require more frequent cleaning. Factors That Affect Cleaning Frequency Several factors determine how often systems should be cleaned: Type of business: Restaurants require more frequent cleaning than offices Usage levels: Higher usage leads to faster build-up Environment: Dust, grease, and humidity increase contamination Regulatory requirements: Compliance with TR19® and health and safety laws System performance: Reduced airflow or efficiency may indicate cleaning is needed Why Regular Cleaning Matters Failing to clean ventilation systems at the correct intervals can lead to: Increased fire risk from grease accumulation Poor indoor air quality affecting staff and customers Reduced system efficiency and higher energy costs Regulatory non-compliance and potential fines Insurance issues due to lack of maintenance records Routine cleaning helps maintain safe, efficient, and compliant systems. The Importance of Professional, Documented Cleaning Working with accredited contractors ensures that cleaning is carried out to recognised standards and properly documented. This provides: Evidence for compliance and inspections Support for insurance claims A clear audit trail of maintenance Professional services ensure systems are cleaned safely, thoroughly, and in line with industry best practices.
