Why it’s worth doing now in Northwick Park
Leaving the canopy until the next full clean can mean months of build-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. Choosing the date yourself beats having a fault choose it for you.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

Canopy cleaning in Northwick Park, done properly
We clean canopies in Northwick Park when the kitchen isn’t cooking: after service, overnight or at the weekend. The equipment underneath is switched off, left to cool and sheeted so the kitchen is ready when we go. Typical jobs include canopy gutters full of old fat and condensation and grease dripping together, on plenum chambers, grease gutters and island canopies.
Kitchens in Northwick Park, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
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, and that’s where we come in.
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours for most canopies. A name and number for whoever controls access to the building in Northwick Park saves time on the night.
- Diagnosis first: we look behind the filters as well as at the hood.
- We protect everything below once it has cooled.
- Heavy deposits come off by hand, then the surfaces are degreased.
- We finish the plenum, troughs and canopy and check them over.
- The canopy is signed off with before and after pictures and a next clean date.
Preparing for the visit
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Part by part
Grease troughs and gutters
Some troughs drain to a cup or drawer, that’s emptied and cleaned too, and we will show staff where it is.
School and staff canteen kitchens
Canteen staff see the canopy, not the duct behind it. The canopy and plenum are both cleaned, so what’s out of sight is dealt with too.
Canopy cleaning around Northwick Park
The FSA’s data shows about 28 bars, pubs and nightclubs and about 3 hotels and guest houses registered across Northwick Park and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Environmental health officers from Harrow council inspect food businesses in Northwick Park. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Northwick Park sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run a church or community hall kitchen, near Saint Cuthberts Church or elsewhere in Northwick Park, its extract still collects grease from every lunch and event. Healthcare kitchens, like those at hospitals such as Northwick Park Hospital (about within half a mile north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

When it’s something else
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- A dirty extract fan further along the system
- Weak extraction caused by a failing fan motor
- Bent or broken filters
If you’re not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Wall canopies
- Baffle filters
- Canopy light fittings
- Plenum chambers
- Grease gutters
- Island canopies
Common problems we fix in Northwick Park
A canopy with gaps around its filters lets grease straight through. The plenum and housing behind them then take far more grease than they should, which shows up as heavy deposits when the filters come out.
Keep an eye out for any of the following:
- Greasy streaks across the canopy
- A canopy flagged at an environmental health inspection
- Grease channels that no longer drain
- Grease filters blocking between washes
Commuter trade near Kenton station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Common questions in Northwick Park
Who is the fire and rescue service for Northwick Park?
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.
Can you come to Northwick Park after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Northwick Park keeps running as normal. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Does a canopy clean meet TR19?
On its own, a canopy clean is a useful extra rather than a full TR19 clean. We will make clear on the report which parts were cleaned, so your records stay accurate.
How long does canopy cleaning take?
That depends on the size of the canopy and how much grease is on it. Typically it takes part of a shift for most kitchens, more where there are several canopies or heavy deposits.
Fixed quotes for canopy cleaning in Northwick Park
The survey tells us what the work involves. The main factors are:
- The scale of the work
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- The condition of the system
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
What to send for a quote
We can often survey from photos. Try to include:
- Any previous report or certificate
- When the site is open and when it’s quiet
- A few general shots of the system
- Problems your staff have spotted
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
