Our kitchen extract cleaning service in WD18
The part of the system nobody sees is often the dirtiest. We reach horizontal runs and vertical risers through access panels, scraping heavy deposits by hand before degreasing. Anything out of reach is noted in the report, and new panels can be fitted. The work covers plenums and filters, vertical risers and horizontal duct runs, and the jobs we see most are a system with no record of a TR19 clean and a new tenancy or takeover with no cleaning history.
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes one visit for most kitchens, while large or complex systems may need more than one.
- We survey the system first, from your pictures and details or on a site visit.
- We measure the grease at set points along the system, then give you a fixed price.
- With the kitchen closed and equipment off and cool, the area is sheeted.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.

Colney Butts: Commuter trade near Watford High Street station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Leave it or put it right?
Putting it off simply moves the grease further down the duct. Over time, soft grease bakes into a harder, thicker crust, and that takes more work to shift. Staying on a regular cycle keeps each clean manageable.

What kitchen extract cleaning can’t fix
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- A duct that’s holed or coming apart
- A fan motor that has burnt out
- A grease trap that needs emptying
Signs you need kitchen extract cleaning
Grease in the extract matters because it burns. Flames from a pan or grill can be pulled into the canopy by the fan, and once grease in the duct catches, fire can spread through the building’s ductwork. For a kitchen in WD18, keeping that fuel under control is part of the fire risk assessment.
Signs it’s time to call us include:
- Heavy grease build-up inside the duct runs
- An inspection that picked up a dirty extract
- An extract that has never been cleaned to TR19
- Grease drips onto cooking equipment
Between visits
Aftercare is simple, and it helps at the next visit:
- Clean the grease filters regularly between TR19 cleans
- Book the next clean before the date on the report
- File each certificate with the fire risk assessment
- Wipe the canopy down at the end of each day
The report gives a recommended date for the next clean, based on your cooking hours and the grease we measured. A 3, 6 or 12-monthly maintenance plan keeps it on track, so the date is not missed.
Keep the outside of the canopy wiped and any grease cups emptied. A daily wipe isn’t a deep clean, but it helps between visits.
WD18 questions
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How much does kitchen extract cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Is WD18 in your area?
Yes. Our technicians work in WD18, as part of our area across London and the South East.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Will the clean disrupt our service?
We clean while the kitchen is closed, so evenings, overnight, early mornings and weekends are all options. We need the equipment switched off and cooled first.
