What we do, step by step
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. In Kingston upon Thames, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Have your last certificate or report to hand
- Arrange a key holder or contact on site

How we handle ductwork cleaning in Kingston upon Thames
Many ducts were installed with too few access doors. Where a section can’t be reached, TR19 expects it to be recorded on the report, and we can fit new access panels so it’s cleaned next time. An honest report beats a guess. If you have grease seeping out of the duct seams and hardened, baked-on grease in long horizontal runs, we can put it right, from vertical risers, horizontal duct runs and bends and junctions onwards.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Kingston upon Thames, that normally means a longer system to clean and more access panels to plan around.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Different parts, different methods
Multi-storey and shared buildings
In a building with several floors, the duct may pass other tenants’ spaces. We plan access with you and the building manager, so the clean is done safely and quietly.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
What affects the cost of ductwork cleaning
The diagnosis comes before the price. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
To speed up the quote, send us:
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Common problems we fix in Kingston upon Thames
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Most sites get in touch when they notice something like this:
- A duct nobody has opened in years
- Years of grease along the duct floor
- Thick deposits at the bottom of a vertical duct
- Gaps where access panels were never fitted
Commuter trade near Kingston station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
Before you book anyone
- Whether they recommend a next date
- Whether they’re fully insured
- Whether the work can be done while the site is closed

Other services in Kingston upon Thames
Kingston upon Thames questions
Which fire and rescue service is responsible for Kingston upon Thames?
That is London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Which council inspects kitchens in Kingston upon Thames?
That is Kingston-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in Kingston upon Thames. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you quote from pictures?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If pictures are not enough, we will survey first.
Do I get a certificate for ductwork cleaning?
A full system clean comes with a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What’s the cleaning interval for extract ductwork?
It follows the same interval as the whole extract, from every 3 months for heavy use to every 12 months for light use. Grease thickness testing shows whether that is often enough.
How long does ductwork cleaning take?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. We plan the work around your kitchen.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What happens if it’s left?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean right away. Putting off the clean only pushes readings higher. Choosing the date yourself beats having a fault choose it for you.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

What ductwork cleaning looks like in Kingston upon Thames
The FSA’s food hygiene register includes about 48 pubs and bars and about 7 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Kingston upon Thames. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Most London extract cleaning happens at night, after the last service. Environmental health officers from Kingston-Upon-Thames council inspect food businesses in Kingston upon Thames. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and 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.
