About our canopy cleaning in Broadwater Farm
Of the whole extract system, the canopy is the bit on show. It’s also the first place cooking vapour meets, so grease gathers on its inner skin, seams and gutters. Our canopy clean covers the shell inside and out, plus the plenum and the filter housing. The work covers island canopies, grease gutters and canopy light fittings, and the jobs we see most are a plenum thick with grease behind the filters and condensation and grease dripping together.
In London, few kitchens can spare a day to close, so work in Broadwater Farm is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: 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.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Broadwater Farm.
- First the canopy is surveyed, by pictures or in person.
- Equipment below is switched off and left to cool, then sheeted.
- Filters come out and the plenum behind them is scraped and degreased.
- Inside and out, the canopy and its grease channels are degreased.
- Clean filters are refitted and before and after pictures go into your report.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand

How the job changes from site to site
Plenums and filter housings
Behind the grease filters is the plenum. It catches whatever gets past the filters, and it’s cleaned every time we clean the canopy.
Pub and hotel kitchens
A hotel or pub kitchen can rarely close for long. We clean the canopy overnight or between services so the kitchen keeps trading.
Aftercare tips
Once we have finished, these simple steps help:
- Give the canopy a wipe after service
- Run the extract the whole time you’re cooking
- Never run the range with a filter out
- Avoid harsh scourers that scratch the canopy
Anything worth knowing goes into the report: damaged filters, gaps around the housing or troughs that need emptying more often. We keep it to what matters.
Tell us if the canopy starts dripping or the filters clog sooner than usual. More drips or quicker clogging often mean the cleaning interval needs looking at, which a grease thickness test can confirm.
When it’s something else
Some problems need a different service or another trade:
- Weak extraction caused by a failing fan motor
- A hood that doesn’t cover the cooking line
- Grease filters too damaged to refit (they need replacing)
If in doubt, call 0345 646 2711 or use the quote form and we’ll say what we think before booking.
Parts of the system we cover
- Baffle filters
- Grease gutters
- Wall canopies
- Island canopies
- Canopy light fittings
- Plenum chambers
Common problems we fix in Broadwater Farm
Moisture in the air mixes with the grease on the canopy. As the canopy cools, condensation forms, carrying grease with it. The result is sticky streaks and drips onto the range.
These are the problems we see most often:
- A plenum thick with grease behind the filters
- Wet, greasy drips from the hood
- Grease dripping from the canopy edge
- A sticky, discoloured canopy
If you run catering at a healthcare site, such as a hospital like North Middlesex University Hospital about 1.3 miles north, the extract may need cleaning more often than a part-time kitchen.

Commuter trade near Bruce Grove station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Volunteers running a hall kitchen near St Philip the Apostle, or anywhere in Broadwater Farm, may not know when the extract was last cleaned, and a grease test settles it.

Why act early in Broadwater Farm
If the canopy waits for the next full clean, grease keeps adding up. In a busy kitchen, the canopy and plenum can need attention between TR19 cleans, and readings or a look behind the filters will show it. Every month a London system goes without attention adds to what has to be done later.

Broadwater Farm: your questions answered
Can school kitchens in Broadwater Farm be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Around Broadwater Farm, the Food Standards Agency lists about 45 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Is parking a problem for work in Broadwater Farm?
A loading bay, a visitor permit or off-street space near the site in Broadwater Farm makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
How much does canopy cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
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.
What information do you need?
A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Is the inside of the hood cleaned?
All of it: the outer surfaces, the inner skin, the seams and the troughs. The plenum behind the filters is included, since that’s where grease hides.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
