A TR19 clean is proven with numbers, not a wipe-down.
TR19® Grease is built on measurement. Before cleaning, the engineer takes grease readings at set points from the plenum behind the filters to the discharge, using a wet film thickness test for soft grease or a deposit thickness test for hard, carbonised deposits.
A mean reading over 200 microns across the system means a complete clean is due, and any single reading over 500 microns needs cleaning straight away. After the clean, every reading has to come in under 50 microns. Those before and after numbers, with photos at each point, are what make the certificate worth something to an insurer.
Ductwork is reached through access panels, which TR19 expects at most every 2 metres and at each change of direction. If parts of your system can't be reached, the report says so and recommends where panels should go, so you know exactly what the certificate covers.

Send a photo for your priceTR19® Grease is the BESA specification for cleaning kitchen extract systems. After a clean to that specification the contractor issues a certificate and post-clean report showing what was cleaned, grease readings and photos, and when the next clean is due. It is the paperwork insurers, landlords and fire risk assessors ask to see.
TR19® Grease sets the interval by daily cooking hours: 2–6 hours a day, every 12 months; 6–12 hours a day, every 6 months; 12–16 hours a day, every 3 months. Heavy-grease cooking such as grills, woks, fryers and charcoal can need more often.
Typical London prices in September 2026 industry guides run £495–£1,200 for a small café, takeaway or pub, £1,200–£2,500 for a restaurant or busy pub, £3,000–£5,000+ for a hotel or multi-kitchen site, plus VAT. Duct length, access and grease levels move the price. Send a photo of your canopy and filters on WhatsApp for a ballpark price for your kitchen.
No. Cleans are booked overnight, after your last service, and finished before morning prep, so you open as normal. The exact start and finish are agreed when you book.
The canopy and plenum, the baffle filters, the ductwork and risers through access panels, the extract fan and the discharge, plus the certificate and before-and-after photo report. If a quote only covers the canopy, it is not a TR19 clean.
Nightshift arranges every clean with an independent, VHR-registered contractor working to the BESA TR19® Grease specification. You get one point of contact for the quote, the booking and your reminders; the certificate is issued by the contractor who did the work.
