Ductwork Extraction & Supply
Ductwork is the circulatory system of your building's ventilation — and like any system, it accumulates contamination over time. Grease, dust, mould and debris build up inside both extraction and supply ducts, creating fire risks, reducing airflow efficiency and compromising indoor air quality. Our specialist ductwork cleaning service covers all duct types and sizes, from light commercial extraction to large-scale industrial supply systems.
What We Do
- Cleaning of extraction ductwork including canopy and grease duct systems
- Supply ductwork cleaning to remove dust, debris and biological contamination
- Access panel installation where required for thorough cleaning and future inspection
- Grease deposit removal to TR19 standard
- Duct integrity inspection and reporting
- Post-clean airflow testing where required
- Full photographic documentation and compliance certification

Fire Risk Reduction
Grease accumulation in extraction ducts is a leading cause of commercial fires. Regular cleaning to TR19 standard is essential for fire safety compliance.
Improved Airflow
Blocked or contaminated ducts restrict airflow, forcing your system to work harder. Clean ductwork restores designed airflow rates and reduces energy costs.
Insurance Compliance
Most commercial property insurers require evidence of regular ductwork cleaning. Our TR19 certificates satisfy insurer requirements.
Better Air Quality
Contaminated supply ducts distribute dust, allergens and pathogens throughout occupied spaces. Clean ducts mean cleaner air for building occupants.
Regulatory Compliance
Building regulations and health & safety legislation require ventilation systems to be maintained in a clean, hygienic condition.
System Longevity
Contamination and grease build-up accelerates corrosion and wear on ductwork and associated components. Regular cleaning extends system life.

Frequently Asked Questions
How often does ductwork need cleaning?
TR19 recommends frequency based on usage. Extraction ducts in heavy-use commercial environments typically require cleaning every 3–6 months. Supply ductwork in office environments may only need cleaning every 2–3 years. We'll advise based on your specific system.
Do you clean both extraction and supply ductwork?
Yes — we clean both extraction and supply ductwork systems across all commercial and industrial building types.
What if my ductwork doesn't have access panels?
We can install access panels as part of the cleaning process. These are required under TR19 and make future cleaning and inspection significantly easier.
Will you provide documentation for our insurer?
Yes. We provide a full TR19-compliant compliance certificate and grease deposit thickness report that satisfies the requirements of most commercial property insurers.
