Cleaning frequency calculator — questions

How does TR19 set frequency? +

By usage hours per day: heavy (12+ hr/day) = every 3 months; moderate (6-12 hr/day) = every 6 months; light (less than 6 hr/day) = every 12 months.

Does cuisine type affect frequency? +

Yes informally. High-grease cuisines (wok, tandoor, fryer-heavy) deposit grease faster. Our calculator adjusts for this where relevant.

What if my last clean was a long time ago? +

Book a TR19 inspection (£180-£450 standalone) — WFT readings will tell you whether the system is currently compliant.
