For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

How we handle ductwork cleaning in Honor Oak
Duct Doctor has cleaned kitchen extract ductwork 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, with each certificate issued through the BESCA portal. The work covers multi-storey ducts, access panels and attenuators, and people most often call us about sections of duct with no access panels and smells of old cooking grease from the ductwork.
In a London area like Honor Oak, 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, so a regular TR19® clean protects everyone in it.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
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. The visit takes from a few hours to more than one visit, depending on duct length and access. If your building in Honor Oak has sign-in rules, permits or key holders, mention them when you book.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need

Behind every canopy among them is a run of ductwork that collects grease out of sight. Food hygiene inspections in Honor Oak are the job of Lewisham council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.

Signs you need ductwork cleaning in Honor Oak
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Clients usually contact us when they notice something like this:
- Smells of old cooking grease from the ductwork
- A duct nobody has opened in years
- Heavy grease at the base of a riser
- Readings above 200 microns from a grease thickness test
If you look after a school kitchen, at a school such as St Francesca Cabrini Primary School or anywhere near Honor Oak, the holidays are the usual time for a TR19® clean.
What your quote should include
- Proof of insurance
- When the next visit should be, and why
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
Different parts, different methods
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. Access is planned with the building’s managers, so the clean is done safely and quietly.
When something else is needed
To be straight with you, some problems need a different fix:
- Fire dampers that don’t close (they need testing and remedials)
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- A duct that is too small or badly routed for the kitchen (a design issue)
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- Attenuators
- Access panels
- Horizontal duct runs

Aftercare tips
After the visit, a few habits help the work last:
- Run the extract fan throughout service
- Leave a way through to the access panels
- Report any grease dripping from duct joints
- Book the next clean before the recommended date
The report names every part of the duct that couldn’t be reached, with the reason. We can fit access panels so those sections are cleaned next time.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. Testing will show whether any section has reached 500 microns.
Your questions about ductwork cleaning in Honor Oak
Which environmental health team covers Honor Oak?
The local authority for Honor Oak is Lewisham council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can a school canteen extract in Honor Oak be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 71 schools and colleges with food registrations within roughly a mile and a half of Honor Oak. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What happens if there aren’t enough access panels?
Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.
How often does extract ductwork need cleaning?
At least as often as BESA guidance sets for your cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
Will I get a report after the ducts are cleaned?
A photo report, with readings and before and after photos, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
How is kitchen extract ductwork cleaned?
Through access panels along the duct. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
How long will the duct clean take?
Allow a few hours for a short run, longer for long runs and tall risers. We will confirm the time when we quote.
