Kitchen Ductwork Cleaning in Hertfordshire
The hidden ductwork is where extract fires take hold. We arrange full duct-run cleans for Hertfordshire kitchens, right out to the discharge point.
Grease that gets past the filters does not disappear. It cools and settles along the ductwork — in the horizontal runs, at every bend and up the risers — and that layer is the fuel an extract fire needs to travel through a building. It is also the part of the system nobody sees, which is why it is so often missed.
We arrange complete ductwork cleaning quotes for kitchens across Hertfordshire, North London, Luton, Bedford and Harlow, through a specialist provider who cleans the full run to the discharge and records the result.
Why it matters in older buildings
Plenty of Hertfordshire and North London kitchens sit in period high-street buildings and parades with flats above, where the duct can climb several floors or run through ceiling voids above other businesses and homes. In January 2025 a restaurant fire on Tottenham High Road damaged the ducting from the ground floor to the roof, and London Fire Brigade said it was caused by deep fat frying with old oil, which spread to contaminated ducting. Long, hidden runs are exactly where a canopy-only clean falls short.
What is involved
The provider surveys the route, opens up the access points and fits new panels where sections cannot otherwise be reached, then cleans each section mechanically — scraping, wiping and vacuuming, with food-safe chemicals for heavy deposits. Readings and photographs at each access point go into the report and certificate.
Access panels
If your ductwork has never had access panels, the first clean may include fitting them. It is a one-off cost that makes every later clean faster and makes the whole run inspectable. The quote will show it separately.

Frequently Asked Questions
Is the whole duct run cleaned?
Yes, from the canopy to the external discharge. Where a section cannot be reached, access panels are fitted so it can be.
Do you need to go into neighbouring units?
Sometimes, where the duct passes through another tenancy or a shared riser. The provider will flag this at survey so access can be arranged in advance.
How is the clean proven?
Grease readings and photographs are taken before and after at the access points and included in the post-clean report and certificate.
