Canopy cleaning for kitchens and businesses in Greenwich
Has the canopy started to drip or look neglected? Send us a photo of the hood and filters when you ring 0345 646 2711, or send details by email, and we’ll send you a fixed quote for canopy cleaning, typically within one working day. If you are dealing with grease dripping from the canopy edge and greasy streaks across the canopy, we can put it right, from canopy light fittings, grease gutters and baffle filters onwards.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Greenwich, that usually means a longer system to clean and more access panels to plan around.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Why act early in Greenwich
Fresh grease comes off far more easily than old. Heat from the range bakes canopy grease into a hard, dark layer, which makes a later clean slower and harder. London sites work long hours, and the longer a job is left, the bigger it gets.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Check all filters are fitted before service
- Avoid harsh scourers that scratch the canopy
- Leave the extract running until cooking stops
- Tell us when the canopy starts to drip
A full system clean comes with a TR19 certificate from the BESCA Vent Hygiene Elite portal. If the job covers only the canopy, the paperwork reflects that.
Don’t let canopy gutters fill to the brim. Most canopy drips start with a full trough, so make emptying them part of the closing routine.
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes an hour or two for one small canopy, longer where there are several. A name and number for whoever controls access to the building in Greenwich saves time on the night.
- The canopy is checked from pictures or on a visit.
- Once the kitchen has closed, the cooking line is cooled and sheeted.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- We put the filters back, tidy up and photograph the finished canopy.
Preparing for the visit
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
- Clear loose items from the work area
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.
Related advice
Signs you need canopy cleaning in Greenwich
However carefully a kitchen in Greenwich is run, the canopy still collects grease. That grease is fuel sitting right above the heat, so a flare-up near a greasy hood can quickly become a fire.
Most sites get in touch after spotting something like this:
- An EHO comment about the canopy
- Poor capture at the hood
- Drips from the canopy onto the range
- Grease filters blocking between washes
Bursars and site managers at schools such as Meridian Primary School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- What records you will receive afterwards
- Whether the quote shows VAT
- Exactly which parts of the system are covered
- Whether a survey comes first
In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

What else we do in Greenwich
How the job changes from site to site
Pub and hotel kitchens
In pubs and hotels, the kitchen may be busy for much of the day. Long hours mean the canopy collects grease fast, and canopy cleans between full cleans can help.
Island canopies
With filters on more than one side, an island canopy has more plenum to clean. Both sides are taken apart and cleaned.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Greenwich questions
Is parking a problem for work in Greenwich?
A loading bay, a visitor permit or off-street space near the site in Greenwich makes the visit easier to plan. Much of our London work is done overnight, which helps.
Which environmental health team covers Greenwich?
The local authority for Greenwich is Greenwich council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How long is a canopy clean?
That depends on the size of the canopy and how much grease is on it. Typically it takes a few hours for most canopies.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Do we need to close the kitchen for a canopy clean?
Out-of-hours cleans are how we work, at night, early in the morning or at weekends. The kitchen is handed back ready to cook.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Why does grease run off the canopy edge?
Most drips come from overflowing troughs, damaged filters or a plenum thick with grease. We clean the canopy, plenum and troughs and tell you what we find.
Grease, kitchens and Greenwich
There are about 426 restaurants, cafés and canteens and about 166 sandwich bars and takeaways within 1.5 miles or so of the middle of Greenwich, 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. Fire safety in Greenwich falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Greenwich get their food hygiene inspections from Greenwich council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run a café or takeaway near Maze Hill station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Greenwich District Hospital is the nearest hospital to Greenwich, about 0.5 miles north-east.
