How we handle canopy cleaning in Greenhill
Canopy cleaning is part of every full TR19® Grease clean, but a canopy can also need cleaning on its own, between full system cleans. Where that is the case, we will be clear that the ducts and fan are not included, so your records stay accurate. The work covers island canopies, baffle filters and wall canopies, and the jobs we see most are overflowing grease troughs and gutters and drips from the canopy onto the range.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Greenhill, that usually means a longer system to clean and more access panels to plan around.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Signs you need canopy cleaning in Greenhill
Steam and condensation make canopy grease harder to deal with. As the canopy cools, condensation forms and runs with the grease. Drips onto the cooking line are a common result.
What we are most often called out for:
- Fat running down the front of the hood
- Filters that clog soon after cleaning
- Poor capture at the hood
- A filter housing caked in grease
Where a hall near Church of St John the Baptist, or anywhere in Greenhill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Tell us when the canopy starts to drip
- Check all filters are fitted before service
- Check filters aren’t leaving gaps
- Wash or exchange the filters on a regular cycle
We point out anything we noticed while the canopy was apart: bent or poorly fitting filters, a light cover that’s cracked, or troughs that fill too quickly. We keep it to what matters.
Keep the fan running throughout service and for a short while after. Turning the fan off early lets vapour settle on the hood.
Why act early in Greenhill
Baked-on grease gets harder to shift the longer it stays. Over months, the heat hardens it into a stubborn coating, which makes a later clean slower and harder. In Greenhill, a planned overnight visit is much easier than closing unexpectedly.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Expect the work in Greenhill to happen after your last customer leaves, not during trading.
- First the canopy is surveyed, by photos or in person.
- Equipment below is switched off and left to cool, then sheeted.
- We remove the grease filters and clean the plenum and filter housing.
- The canopy is cleaned inside and out, including troughs and seams.
- Filters go back, the area is cleaned down and pictures are taken.
Before we arrive
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
Get a fixed quote
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
What canopy cleaning looks like in Greenhill
The FSA’s data shows about 23 pubs, bars and clubs and about 3 hotels and B&Bs registered within about 1.5 miles of central Greenhill. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In Greenhill, food businesses are inspected by environmental health officers from Harrow council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Greenhill sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Commuter trade near Harrow-on-the-Hill station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. If you look after a school kitchen, at a school such as Saint Jerome Church of England Bilingual School or anywhere near Greenhill, the holidays are the usual time for a TR19® clean.

What affects the cost of canopy cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the system

- One-off work versus a regular cycle
- Parking and loading at the site
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
