Kitchen duct cleaning in London, done overnight.
The ductwork is where kitchen fires spread, and the part a canopy wipe never reaches. We clean the full run, horizontal sections and risers, through access panels, overnight, with grease readings before and after.

If the duct can't be reached, it can't be certified.
Most London kitchens were fitted with too few access panels, especially in older buildings and converted units. TR19® Grease expects openings at a maximum of 2 metres apart and at each change of direction, so an engineer can reach every internal surface.
On the first visit the engineer maps your ductwork, cleans everything that can be reached and lists anything that can't, with a recommendation for where new panels should go. Fitting panels is usually quick and makes every later clean cheaper and fully certifiable.
Ask for this before you book anywhere: a certificate that quietly leaves out half the duct is the one an insurer looks hardest at after a fire.

Then parts of it cannot be cleaned or certified. The engineer cleans what can be reached, records what can't and recommends where panels should be fitted. TR19 expects openings at most 2 metres apart and at every change of direction.
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.
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.
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.
