What a TR19 clean covers
The whole extraction system, cleaned as one, by Umair Hussain. Every clean is priced in writing after a free site survey, before any work starts.
Canopy and filters
Filters removed and degreased; canopy interior and underside cleaned back to metal.
Plenum
The void behind the filters, where grease collects out of sight, cleaned in full.
Ductwork
Every section we can reach through access panels, with any section we cannot reach named on the report.
Extract fan
Fan, impeller and housing degreased, so grease is not thrown back into the duct.
Readings and photos
Grease thickness measured before and after at the same points, with dated photographs.
Report and certificate
A post-clean verification report and a certificate with a number anyone can check online.

TR19 cleaning in Hertfordshire: questions
Which parts of Hertfordshire do you cover?
We cover the listed towns in Hertfordshire that fall within 70 miles of Peterborough, including Royston, Baldock, Letchworth, Hitchin, Stevenage, Bishop's Stortford. Places up to 45 miles away are in our core area and covered regularly; the rest are booked on request.
Who enforces fire safety for commercial kitchens in Hertfordshire?
Hertfordshire Fire and Rescue Service enforces the Regulatory Reform (Fire Safety) Order 2005 in Hertfordshire. The duty to manage fire risk, including grease in the extraction system, sits with the responsible person. TR19 Grease is BESA guidance, not law.
How often does a kitchen extract system in Hertfordshire need cleaning?
BESA TR19 sets the interval by how many hours a day the kitchen cooks: 12 to 16 hours, every 3 months; 6 to 12 hours, every 6 months; 2 to 6 hours, every 12 months. Your insurance policy may set its own condition, so check it alongside TR19.
How much does TR19 cleaning cost in Hertfordshire?
Every clean is priced in writing after a free site survey, before any work starts. The price depends on the number of canopies, the length and access of the ductwork and the fan, which is why we survey first. The survey is free and there is no obligation.
