About kitchen extract cleaning in SL9
A kitchen extract system is far more than the canopy you can see. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, and grease settles in every one of them. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. Common call-outs are for a smoky, hot kitchen with weak extraction and heavy grease build-up inside the duct runs, on canopies and hoods, plenums and filters and horizontal duct runs.
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes anything from a few hours to a full night, depending on the size of the system.
- We start with a survey, so we know every part of the system before we quote.
- We measure the grease at set points along the system, then give you a fixed price.
- On the day, cooking equipment is switched off and left to cool, and everything nearby 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.

Kitchen extracts across SL9
Kitchens across SL9 cook for very different hours, from all-day town-centre sites to part-time hall and school kitchens. The right interval comes from hours of use and grease readings.
In England, the Fire Safety Order puts the duty on the responsible person to assess and reduce fire risk, and each certificate and photo report is a record you can keep in your log book.
Chalfont St Peter: Term dates shape school work: for a school like Chalfont St Peter CofE Academy, an extract clean fits neatly into a half-term or summer break. Chenies Manor House, about 4.8 miles north, is one of the historic houses near Chalfont St Peter; if you run event catering at a venue like that, cleans can be booked between functions.
Part by part
Schools, hospitals and care homes
Some healthcare kitchens never fully close. We plan the clean around meal times and work in a contained, tidy way, so residents and patients are not disturbed.
Ductwork and risers
Long flat runs of duct are where grease collects. Each run is cleaned through its access panels, recording any that cannot be reached.
Fixed quotes for kitchen extract cleaning in SL9
Sites vary more than people expect. The main factors:
- How big the system is
- Whether several sites go on one quote
- What state the system is in
- Any permits to work or inductions
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
What happens if it’s left?
Putting it off simply moves the grease further down the duct. Over time, soft grease bakes into a harder, thicker crust, which is slower to clean. Regular cleans keep each visit shorter.
Comparing quotes
- Whether a written report and photos are included
- If the quote is a fixed price or an estimate
- Proof of insurance
- When they can work, and whether that is outside your opening hours
What we’re called out for in SL9
It’s common for parts of a duct to have been missed for years. Most of the time it’s because there were never enough access panels, so nobody could get to them. Grease in those sections keeps building out of sight.
These are the problems we see most often:
- Missing paperwork after a change of operator
- An extract that no longer clears the smoke
- Grease smells coming from the extract
- Years of baked-on grease in the ducts
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Keep to the recommended cleaning interval
- Flag any change in how the extract sounds or works
- Wipe the canopy down at the end of each day
- Keep the extract on whenever the range is lit
When the clean is finished, grease readings are taken again at the same points, so you can see the difference in numbers as well as pictures. A TR19 certificate follows, issued through the BESCA Vent Hygiene Elite portal.
Clean the grease filters often, not just on clean day. Clean, well-fitted filters catch more fat before it reaches the duct, which slows build-up further down the system.
Your questions about kitchen extract cleaning in SL9
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
How long does it take to clean a kitchen extract system?
That depends on the size of the system, the amount of grease and the number of access points. Most jobs take one visit for most kitchens, while large or complex systems may need more than one.
How much does kitchen extract cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711 or send us an email with the site type, opening hours and a few pictures.
Which parts of the extract do you clean?
The whole system: the canopy, the plenum behind the filters, the filters, horizontal ducts, vertical risers, the fan and the discharge, plus attenuators where fitted. Any part without access is noted.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
