Canopy cleaning for kitchens and businesses in Longfield
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. The work covers plenum chambers, grease gutters and canopy light fittings, and common reasons people get in touch are a plenum thick with grease behind the filters and fat running down the front of the hood.
Somewhere as small as Longfield, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How the job changes from site to site
Wall canopies
Wall canopies sit against a wall over a cooking line. Grease often collects where the canopy meets the wall, so we clean along it as well as the inner skin.
Island canopies
Island canopies hang over cooking in the middle of the kitchen, so every face can collect grease. We clean all of them, inside and out.
Longfield kitchens: local notes
There are about 6 cafés, restaurants and staff canteens and about 6 sandwich bars and takeaways within roughly a mile and a half of the centre of Longfield, according to the Food Standards Agency’s register. Wherever there’s a canopy over the cooking, its hood and plenum collect grease with every service. Kent Fire and Rescue Service covers Longfield. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Dartford council that sends environmental health officers to food businesses in Longfield. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Bursars and site managers at schools such as Longfield Academy tend to book extract cleaning for when the kitchen is empty. Where a hall near Church of Saint Mary Magdalene, or anywhere in Longfield, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Darent Valley Hospital is the nearest hospital to Longfield, about 3.3 miles north-west.

Longfield questions
Can you clean school kitchen extracts in Longfield during the holidays?
Yes, holiday work suits schools best. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Longfield. Just give us a ring on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Can you work in Longfield outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Longfield can fit around your hours. Your opening times are the first thing we ask for.
What happens to the waste?
We take it away when we go. During the work, it’s contained so the area stays clean.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or drop us a line.
What happens to the filters during the clean?
Filters are removed so we can clean the plenum and housing, then cleaned and refitted. We also offer a filter exchange service for between cleans.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep grease cups and drawers emptied
- Tell us when the canopy starts to drip
- Use non-abrasive cloths on the hood
- Make sure filters sit tight in the housing
Keep the photo report with your maintenance log, so it’s ready when an EHO, insurer or fire officer asks. Photos of a clean canopy and plenum make the record easy to follow.
Wipe the canopy surfaces at the end of each day. It won’t replace a professional clean, but it slows the build-up you can see.

The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. If the van will struggle with a lane or gateway near Longfield, let us know and we will plan around it.
- First the canopy is surveyed, by photos or in person.
- The range is turned off and allowed to cool before we cover it.
- We remove the grease filters and clean the plenum and filter housing.
- We degrease the canopy shell, its seams and the grease troughs.
- Filters go back, the area is cleaned down and pictures are taken.
Before we arrive
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need

Advice
Managing agents and facilities teams in Longfield
We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building to keep disruption down.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
What happens if it’s left?
Grease on the canopy is sitting just above the heat source. Flames from the range can ignite it and be pulled further into the system, where a fire is much harder to stop. Cleaning it removes that fuel. Systems in rural buildings are often out of sight and out of mind.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
