Ductwork cleaning for kitchens and businesses in Avery Hill
We have been trading since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. If you have readings above 200 microns from a grease thickness test and a duct clean needed for an insurer, we can put it right, from access panels, vertical risers and bends and junctions onwards.
In a London area like Avery Hill, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Common problems we fix in Avery Hill
A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Panels along the riser make proper cleaning possible.
Any of these means the system needs a check-up:
- Years of grease along the duct floor
- A rancid smell from the extract duct
- An insurer asking for TR19 evidence
- A duct nobody has opened in years
A hall kitchen that only cooks for events, whether near Church of Holy Trinity or elsewhere in Avery Hill, still needs its extract cleaned, just less often.

Grease, kitchens and Avery Hill
There are about 152 cafés, restaurants and staff canteens and about 96 sandwich bars and takeaways in Avery Hill and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. London Fire Brigade covers Avery Hill. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Avery Hill, food businesses are inspected by environmental health officers from Greenwich council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Term dates shape school work: for a school like Stationers' Crown Woods Academy, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Avery Hill is Eltham Community Hospital, about 1 mile west.
Avery Hill is about 1 mile north-east of Eltham, in Greater London. Anywhere in SE9, we cover ductwork cleaning for commercial sites. Our Greater London coverage runs to 764 places, and Avery Hill is one of them. For sites nearby, see our London page (8 miles or so).
Work in SE9, DA15 and DA16 follows the same survey, fixed quote and written report as everywhere else we cover.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Night and weekend working is normal for us in London, and a site in Avery Hill is no exception.
- We start by working out how the duct runs and where it can be opened.
- Grease readings are taken at set points along the duct.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Let us know about permits to work or site inductions
- Tell us where we can park and unload
- Make sure someone can let us in and lock up afterwards

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.
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. We test those as a separate job.
How we price ductwork cleaning
There’s no set price list, because sites vary so much. What we look at:
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- How many systems or sites are involved
- The size of the system
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
What we need to know
When you call or email, these details help:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
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.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Your questions about ductwork cleaning in Avery Hill
Can a school canteen extract in Avery Hill be done out of term time?
Yes, and it’s the easiest time to do it. Around Avery Hill, the Food Standards Agency lists about 48 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711 or drop us a line with the dates the site is empty.
What do you need to know about parking in Avery Hill?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, usually makes it simpler.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then call 0345 646 2711, or email photos.
How can I tell if my extract ducts are dirty?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
When is the ductwork cleaned?
When the kitchen is closed. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
Looking after it afterwards
Results last longer with the right care. We suggest:
- Flag drips from the duct right away
- Leave a way through to the access panels
- File each certificate and photo report in the maintenance log
- Consider fitting panels where the report shows gaps
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Grease and dirty water are contained and removed.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
