The Risks of Leaving It.

What Happens If It's Not Cleaned.

  • Airborne bacteria & mould

    Biological growth on coils, trays and duct linings is distributed through the building, risking infection control in healthcare and education settings.

  • Legionella risk

    Stagnant water in humidifiers, drip trays and dead legs makes ventilation plant a control point under ACOP L8 — it must be maintained and evidenced.

  • Occupant sickness & absenteeism

    Fouled supply air is a documented contributor to Sick Building Syndrome and lost productivity.

  • Failed compliance audit

    TR19 Air, BS EN 15780 and HTM 03-01 all require measured, evidenced cleanliness; without records, audits and approvals stall.

  • ✓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.
