Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Canopy cleaning for kitchens and businesses in Cockfosters
Grease troughs, seams and the inside edge of the canopy are the spots a daily wipe misses. Thick deposits are scraped off by hand, then the surfaces degreased to suit what’s there, using hot water or steam where it helps. Typical jobs include a plenum thick with grease behind the filters and an EHO comment about the canopy, across grease gutters, plenum chambers and canopy light fittings.
Kitchens in Cockfosters, like many across London, can share a building with flats or offices, with the duct running up through shared risers. 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.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What canopy cleaning can’t fix
Not every problem is solved by canopy cleaning, and we’d rather say so up front. It won’t put right:
- Bent or broken filters
- Poor airflow from a fan that needs repair
- Grease in the duct runs and risers behind the canopy
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think before you book.

Questions from Cockfosters
Do you do school kitchen extract cleaning in Cockfosters in the summer holidays?
Yes. The holidays are the usual time for school work. Around Cockfosters, the Food Standards Agency lists about 32 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you work in Cockfosters outside opening hours?
Yes, nights and weekends are routine for us. That way a site in Cockfosters doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What does canopy cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Why is my canopy dripping grease?
Usually because the troughs or gutters are full, or the plenum is overloaded. With nowhere to collect, the grease overflows, and condensation can carry it too. Cleaning the canopy and plenum clears it.
Can I just have the canopy cleaned instead of the whole system?
You can have the canopy cleaned on its own, but it won’t cover the ductwork or fan. TR19 Grease covers everything the grease travels through, at intervals set by BESA guidance.
Do we need to close while you work?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
Canopy cleaning around Cockfosters
The Food Standards Agency lists about 21 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses as registered food businesses across Cockfosters and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Cockfosters sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A kitchen near New Barnet station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you run catering at a healthcare site, such as a hospital like Chase Farm Hospital about 2.5 miles north-east, the extract may need cleaning more often than a part-time kitchen.
Cockfosters is about 1 mile east of Barnet, in Greater London. We provide canopy cleaning for commercial premises of every kind in Cockfosters and the rest of Greater London. Cockfosters is one of 764 places in Greater London where we work for commercial clients. For sites nearby, see our London page, about 11 miles away.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
How we price canopy cleaning
A fixed price needs a few facts first. We check:
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- One-off work versus a regular cycle
- Where the site is and how we reach it
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What to send for a quote
To speed up the quote, please include:
- Problems your staff have spotted
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. We fit London jobs around the building rather than the other way round, so a visit in Cockfosters is normally out of hours.
- First the canopy is surveyed, by photos or in person.
- Equipment below is switched off and left to cool, then sheeted.
- With the filters out, the plenum and housing are cleaned back.
- Inside and out, the canopy and its grease channels are degreased.
- Filters go back, the area is cleaned down and pictures are taken.
Preparing for the visit
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
Related advice
When to call us in Cockfosters
The plenum is hidden behind the filters, so nobody sees it build up. Daily cleaning reaches the canopy face but rarely gets further, so the plenum often carries months of grease.
It’s time to book a visit if you see:
- A filter housing caked in grease
- Condensation and grease dripping together
- A canopy flagged at an environmental health inspection
- Overflowing grease troughs and gutters
A hall kitchen that only cooks for events, whether near Christ Church or elsewhere in Cockfosters, still needs its extract cleaned, just less often.

Leave it or put it right?
A blocked plenum and clogged filters cut the airflow at the canopy. The kitchen gets hotter and smokier, and the fan works harder for less. Cleaning restores the path the air should take. Every month a London system goes without attention adds to what has to be done later.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
