Specialist cleaning for the system behind your kitchen
Duct Clean London provides specialist duct, canopy, extraction fan and kitchen air-system cleaning across North West, West and Central London. We work with restaurants, takeaways, hotels and school kitchens, and assess residential and laundry ventilation enquiries to match the service to the system.
Every visit starts with your premises: the equipment installed, operating hours, grease or dust build-up and the access available. We explain what the quote includes, plan the cleaning window and identify concealed or difficult-to-reach sections before work begins.
From a focused canopy clean to a coordinated extraction-system clean, our aim is practical maintenance with a clear record. Send your postcode and photographs of the canopy, ductwork and fan so we can discuss the right next step.
The whole extraction route
We look beyond the visible canopy, considering filters, accessible duct runs and the extraction fan as part of the agreed scope.

Duct cleaning questions, answered
Cleaning frequency depends on cooking hours, processes, grease accumulation and system condition. Tell us about your operation and previous cleaning records so the next visit can be planned appropriately. A certificate records completed work; it does not mean a system will remain clean for a fixed period. Read our full guide on how often kitchen extraction should be cleaned.
The quote reflects canopy size, duct length, fan position, contamination and access. Out-of-hours work or specialist access equipment may affect the price. We agree the work to be carried out before booking rather than applying one price to every system.
A canopy clean covers the surfaces and components listed in your quote. Duct runs, extraction fans and difficult-to-access sections need to be included explicitly. Ask for the full extraction route to be reviewed if you need a connected system clean.
Yes, evening and after-hours visits can be arranged. Confirm closing times, safe access, isolation arrangements and when equipment will be cool. Please tell us about parking, noise or building-management restrictions.
Send your property type, full site address, and contact details through the booking form. Photographs and previous reports help us assess access. We will contact you to discuss scope and availability before an appointment is confirmed.
We focus on North West, West and Central London, including enquiries within Zones 1–4. Send your full postcode so we can confirm availability, parking and access.
Yes, we assess residential and laundry enquiries. Tell us what the system serves and send photographs so we can check its materials, access and cleaning requirements.
Send clear photographs of the canopy, filters, accessible ductwork and extraction fan or motor. A wider photograph showing access is useful too. Only take photographs from a safe, accessible position.
Cleaning removes accessible deposits. Electrical faults, damaged bearings, poor installation or an undersized system may need a separate assessment or repair.
We review your site details and contact you to discuss access, scope and availability. Sending the form is an enquiry; your visit is confirmed after arrangements are agreed.

What makes a duct cleaning service effective?
An effective clean is one you can prove. Grease inside the duct should be measured before and after the clean, every reachable section from canopy to roof fan should be photographed, and anything that couldn't be reached should be named in writing. A shiny canopy proves nothing: the fire risk sits inside the ductwork and the fan.
Five signs a clean was done properly
- Grease was measured, not just looked at. Under BESA's TR19 Grease standard, the average grease deposit in the duct must stay below 200 microns between cleans, and any spot at 500 microns or more needs cleaning straight away. Your report should show the readings before and after.
- The whole route was cleaned. Canopy, filters, plenum, ductwork, fan and discharge, not just the parts you can see from the kitchen.
- There are photos of every section. Before and after shots of the inside of the duct and the fan, not only the canopy.
- Gaps are written down. In older London buildings, risers often have no access panels. A reliable contractor tells you which sections they couldn't reach and recommends fitting panels there, rather than certifying the full system anyway.
- You get a TR19 report and certificate you can show your insurer. Insurers increasingly expect documented TR19 Grease cleaning, and a missing record can put a fire claim at risk.
How often does your kitchen need cleaning?
TR19 Grease bases the interval on measured grease levels, but kitchen type and daily cooking hours give a starting point:
| Grease level | Typical kitchen | Up to 6 hrs/day | 6–12 hrs | 12–16 hrs | 16+ hrs |
|---|---|---|---|---|---|
| Low | Cafés, light cooking | 12 months | 12 months | 6 months | 6 months |
| Medium | Most restaurants | 12 months | 6 months | 4 months | 3 months |
| High | Grills, fryers, woks, takeaways | 6 months | 3 months | 3 months | 2 months |
Charcoal grills, woks and deep fryers put far more grease into the ductwork than a café does. Many of the Middle Eastern and Japanese restaurants we clean for sit in the high row.
Questions to ask any duct cleaning company in London
- Will you measure grease thickness before and after, and include the readings in the report?
- Does the quote cover the ductwork and fan, or only the canopy?
- What happens to sections you can't reach?
- Who signs off the certificate, and what qualification do they hold?
- Can you work after closing time? (We do: evenings and overnight.)
What does it cost?
Price depends on canopy size, duct length, fan position, grease level and access, so we don't use a fixed price list. Send photos of your canopy, filters, ductwork and fan and we'll give you a free written quote, usually without a site visit.
