Overview.
Air Duct Cleaning
We provide expert air duct cleaning services for commercial premises across Chester, Shropshire, and surrounding areas. Clean ventilation and ductwork systems are essential for maintaining good indoor air quality, preventing odours, and ensuring compliance with HVAC hygiene regulations.
Poorly maintained air ducts can harbour dust, allergens, mould, bacteria and even pests — all of which impact air quality and occupant health. Our services are fully compliant with TR19 and BS EN 15780 guidelines.

Standards We Work To.
The Benchmarks This Service Is Completed To
- BS EN 15780:2011
The European standard for ventilation ductwork cleanliness. We classify your system, clean to the agreed class and verify it with measured deposit results.
- BESA TR19® Air
The UK specification for internal cleanliness of non-grease ventilation systems, covering inspection frequency, cleaning method and verification.
- HSE HSG 202 / Approved Document F
Ventilation must provide adequate, clean air. Our records evidence that ducted supply and extract systems are maintained accordingly.
- HTM 03-01 (healthcare)
For clinical and healthcare premises we work to the specialised ventilation guidance, including validation and permit-to-work requirements.
- Workplace (Health, Safety and Welfare) Regulations 1992
Regulation 6 requires effective and suitably maintained ventilation — the hygiene certificate is your proof of compliance.
The Risks of Leaving It.
What Happens If It's Not Cleaned.
Poor indoor air quality
Dust, allergens, mould and bacteria accumulating in ductwork recirculate into occupied spaces, triggering allergies, respiratory complaints and staff sickness.
Compliance with workplace law
The Workplace Regulations and Approved Document F require effective, maintained ventilation; without evidenced cleaning that duty goes undocumented.
HVAC inefficiency & cost
Fouled ducts and coils force fans to work harder, raising energy consumption and shortening plant life.
Mould & odour
Damp, dusty ducts are an ideal substrate for mould growth, producing persistent stale odours that reach every room the system serves.
Why Compliance & Insurance Demand This Clean.
Evidence That Protects Your Business.
- ✓Regulatory Reform (Fire Safety) Order 2005The Responsible Person must manage fire risk in extract systems and evidence it — our dated certificate and photographic record discharge that duty.
- ✓Insurer policy conditionsDocumented, dated TR19-compliant cleaning is routinely a condition of cover; missing maintenance records can give an insurer grounds to refuse a fire claim.
- ✓Evidence for auditorsPhotographic before/after, measured deposit readings and a dated certificate accepted by fire risk assessors, Environmental Health Officers and insurers.
- ✓Year-round continuityRecommended re-clean intervals set to your usage keep you compliant between visits, not just on the day of the clean.
