Canopy cleaning in Downham, done properly
Canopy cleaning is part of every full TR19® Grease clean, but a canopy can also need cleaning on its own, between full system cleans. In that case, the report makes clear what was and wasn’t cleaned, so your records stay accurate. The work covers grease gutters, plenum chambers and baffle filters, and people most often call us about filters that never seem to stay clean and heavy deposits behind the grease filters.
Kitchens in Downham, 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.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What canopy cleaning can’t fix
We won’t sell you work that does not address the problem, so here are the limits:
- Weak extraction caused by a failing fan motor
- Faulty canopy lights or wiring (a job for an electrician)
- A hood that does not cover the cooking line
If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think before you book.
Parts of the system we cover
- Island canopies
- Wall canopies
- Canopy light fittings
- Plenum chambers
- Baffle filters
- Grease gutters
Between visits
Think of this as the after-treatment advice, short and simple:
- Clean the hood’s outer surfaces daily
- Report new drips or smells from the canopy
- Clean the baffle filters often
- Empty the grease troughs before they fill
We clear away the sheeting, waste grease and water before we leave. Filters are back in place and seated properly ready for the next service.
Wipe the canopy surfaces at the end of each day. It will not replace a professional clean, but it slows the build-up you can see.
Canopy cleaning around Downham
Food Standards Agency records include about 24 pubs, bars and clubs and about 3 hotels, B&Bs and guest houses across Downham and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. London jobs normally start after the last service, with loading and roof access agreed with the building first. It’s Lewisham council that sends environmental health officers to food businesses in Downham. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
Bursars and site managers at schools such as Rangefield Primary School tend to book extract cleaning for when the kitchen is empty. If you run a church or community hall kitchen, near St Barnabas or elsewhere in Downham, its extract still collects grease from every lunch and event.

Why act early in Downham
For a kitchen in Downham, a canopy that looks greasy can colour a whole inspection. A clean hood is a sign the kitchen is cared for, and it’s far easier to keep clean than to rescue. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Questions from Downham
How do you handle parking and loading in Downham?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Which fire and rescue service is responsible for Downham?
Fire safety enforcement in Downham is handled by London Fire Brigade. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you have insurance?
Yes. We carry full insurance, and we’ve been trading since 2009.
Do you clean canopies in all kinds of kitchens?
Single hoods, long wall canopies and island canopies alike. We work out the approach when we survey, from pictures or a visit.
Why is my canopy dripping grease?
Full gutters and a heavily coated plenum are the common causes. Grease has nowhere else to go, so it runs down and drips, and condensation can carry it too. Cleaning the canopy and plenum clears it.
Will we have to shut during the visit?
Not usually. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Common problems we fix in Downham
Air straight off the range hits the canopy first. Fat in that air settles on the inside of the hood, in its seams and on the filters, and the plenum behind them collects the rest.
Most sites get in touch when they notice something like this:
- An EHO comment about the canopy
- Grease dripping from the canopy edge
- Overflowing grease troughs and gutters
- Condensation running down the canopy
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Bromley Hospital is the nearest hospital to Downham, about 2.1 miles south.

Fixed quotes for canopy cleaning in Downham
Before we fix a price, we need to know a few things. We check:
- The condition we find in the survey
- Site rules, permits and inductions
- One-off work versus a regular cycle
- How big the system is
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or send us an email, and we’ll explain what it covers.
What we need to know
You do not need the technical terms. Just send:
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- The postcode and the type of business
- The times we could work without disrupting the site
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.
What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. In Downham, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- Diagnosis first: we look behind the filters as well as at the hood.
- We protect everything below once it has cooled.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after photos and a next clean date.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in
Getting a quote
For a fixed quote, give us a ring on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Advice
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
