Laundry extract ductwork plays a crucial role in maintaining hygienic and comfortable conditions in residential, commercial, and healthcare facilities. Over time, humidity, lint, dust, and other particulates can accumulate within the system, creating a fire hazard, promoting microbial growth, and reducing the efficiency of connected appliances. Ensuring that your laundry extract ductwork is clean and maintained not only protects your building and equipment but also safeguards the health and wellbeing of occupants and staff.
Regular cleaning and inspections of laundry extract systems are essential for compliance with UK health and safety regulations, including BESA TR19 Guidelines and the Workplace (Health, Safety and Welfare) Regulations 1992.
Professional maintenance from Marlowe Environmental Services prevents dangerous build-ups, ensures proper airflow, and minimises the risk of fire or system failure. With a robust cleaning schedule, building owners and managers can maintain safe, fully compliant ductwork while optimising HVAC performance and reducing long-term operational costs.
Laundry extract systems remove humidity and particulates generated during the drying process. This helps maintain hygienic, safe, and comfortable conditions for occupants or staff.
However, the combination of heat, moisture, and airborne debris can lead to significant buildup within the extract system. If not cleaned regularly, this accumulation can create several hazards:
Laundry extract cleaning removes many contaminants commonly found in these systems:
Particulates – Dust, dander, soot, pollen, and smoke particles
Microbes – Bacteria, viruses, fungi, spores, and mould
Gases & Odours – Volatile compounds released from cleaning chemicals, insulation, furniture, or carpets
Laundry extract systems accumulate contaminants faster than typical ventilation systems, meaning multiple cleanings per year are often necessary to maintain compliance and prevent fire hazards.
A blocked or contaminated system can also compromise safety devices, such as fire dampers, allowing fire to travel through the ductwork unhindered.
Marlowe Environmental Services carries out all cleaning in line with UK health and safety legislation and industry standards:
Management of Health & Safety at Work Regulations 1999 – Employers must assess risks to employees and others
Workplace (Health, Safety and Welfare) Regulations 1992 – Mechanical ventilation systems must be cleaned as appropriate and provide sufficient fresh air (Regulations 5 & 6)
ACOP 6 (52) – Ventilation systems should be regularly cleaned, tested, and maintained to prevent contamination
BS EN 15780 – Benchmarks for cleanliness in ventilation systems
BESA TR19 – Internal Cleanliness of Ventilation Systems guidelines
Compliance with these standards ensures your system operates efficiently, reduces fire risk, and maintains healthy indoor air quality.
