How we handle canopy cleaning in Whetstone
The canopy is the part of the extract everyone in the kitchen sees. 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. Typical jobs include smoke hanging around the canopy during service and condensation running down the canopy, on wall canopies, island canopies and canopy light fittings.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Whetstone, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Insurers, fire officers and environmental health officers all look at records. That is 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.

How the job changes from site to site
Wall canopies
Long wall canopies often have several filter banks. We work along the canopy section by section, with pictures for each.
Pub and hotel kitchens
Few pubs and hotels can shut the kitchen for a day. We clean the canopy overnight or between services so the kitchen keeps trading.
What we do, step by step
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. In a London area like Whetstone, parking, loading and building access are planned before the day of the work.
- We start by checking the canopy and what’s behind its filters.
- 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.
- You get pictures of the result and a recommended date for the next clean.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Whetstone and across Greater London. Larger estates can be phased building by building to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Whetstone kitchens: local notes
The FSA’s food hygiene register shows about 139 restaurants, cafés and canteens and about 52 takeaways and sandwich shops within 1.5 miles or so of the middle of Whetstone. Where they cook under a hood, the plenum behind the filters is where grease hides. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. Kitchens in Whetstone get their food hygiene inspections from Barnet council. 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.
Commuter trade near Oakleigh Park station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Finchley Memorial Hospital is the nearest hospital to Whetstone, about 1.4 miles south.
Whetstone is about 7 miles north of St Pancras, in Greater London. Across the N12 area, we can carry out canopy cleaning at your premises. 764 places in Greater London are on our list, from busy centres to quieter spots. There’s also a page for London, roughly 9 miles from Whetstone.
We cover every part of the N12, N20 and N11 postcode area for canopy cleaning and the roads nearby. You will find streets such as High Road, Swan Lane and Dene Road, and we cover them all for canopy cleaning.

Leave it or put it right?
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. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.

Signs you need canopy cleaning in Whetstone
Grease that runs down the inside of a canopy gathers in its gutters and troughs. If they’re not emptied, they fill and overflow, so fat ends up running down the front of the hood.
Common reasons sites call us include:
- Heavy deposits behind the grease filters
- Smoke hanging around the canopy during service
- A sticky, discoloured canopy
- Wet, greasy drips from the hood
Where a hall near Church of St John, or anywhere in Whetstone, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What else we do in Whetstone
How we price canopy cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- Parking and loading at the site
- Site rules, permits and inductions
- The condition of the system
- How easy every part is to reach
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.
What we need to know
To speed up the quote, send us:
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
For a fixed quote, give us a ring on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
FAQs for Whetstone
What do you need to know about parking in Whetstone?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, typically makes it simpler.
Can school kitchens in Whetstone be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 47 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Whetstone. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Do you provide pictures of the cleaned canopy?
You get a photo report with before and after photos. Full system cleans also come with a TR19 certificate.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Do you clean inside the canopy as well as outside?
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.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
