Canopy cleaning in North Cheam
We’ve been cleaning kitchen canopies since we started trading in 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001. The work covers grease gutters, wall canopies and plenum chambers, and people most often call us about condensation running down the canopy and canopy gutters full of old fat.
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. In North Cheam, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Fixed quotes for canopy cleaning in North Cheam
We do not publish a price list, because no two systems are the same. The quote depends on:
- Any permits to work or inductions
- The size of the system
- A single visit or a regular plan
- The condition of the system
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Helping us quote
We can often survey from pictures. Try to include:
- Problems your staff have spotted
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Questions from North Cheam
Do you do school kitchen extract cleaning in North Cheam in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around North Cheam, the Food Standards Agency lists about 28 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in North Cheam outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in North Cheam can fit around your hours. Just give us a ring on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you clean the grease filters as part of a canopy clean?
We take them out, clean them and put them back. We also offer a filter exchange service for between cleans.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711 or use the quote form.
Aftercare tips
How long the results last depends on use and care. We suggest:
- Report new drips or smells from the canopy
- Make sure filters sit tight in the housing
- Keep filters on a set cleaning routine
- Avoid harsh scourers that scratch the canopy
File the report alongside your fire risk assessment where an inspector can see it. Photos of a clean canopy and plenum make the record easy to follow.
Run the extract for as long as anything is cooking. Turning the fan off early lets vapour settle on the hood.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes a few hours for most canopies. In North Cheam, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- The canopy is checked from photos 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.
- Filters are refitted, the area cleaned down and the photo report put together.
Preparing for the visit
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
Getting a quote
To get a fixed quote, phone us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.

What else we do in North Cheam
North Cheam kitchens: local notes
Food Standards Agency records list about 200 cafés, restaurants and staff canteens and about 96 takeaways and sandwich shops in North Cheam and the streets around it, up to about 1.5 miles out. Every kitchen among them that cooks under a canopy has a hood, plenum and filters collecting grease. North Cheam 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. In North Cheam, food businesses are inspected by environmental health officers from Sutton council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
Commuter trade near West Sutton station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Healthcare kitchens, like those at hospitals such as St. Anthony's Hospital (about 0.6 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.
North Cheam is about 3 miles north-east of Epsom, in Greater London. Across the SM3 area, we can carry out canopy cleaning at your premises. Across Greater London, we cover 764 places, North Cheam among them. There’s also a page for London, roughly 10 miles from North Cheam.
Canopy cleaning in SM3, KT4 and SM1 follows the same survey, fixed quote and written report as everywhere else we cover.

What’s near North Cheam
In North Cheam, that means kitchens and buildings near The Nonsuch Inn, Sutton College of Learning for Adults and Nonsuch Park, among other places. For rail, the closest station is West Sutton station, about 0.8 miles south-east of the centre. Other landmarks nearby include Chessington Castle Hill (3.2 miles west) and St. Anthony's Hospital (0.6 miles north). The countryside around North Cheam includes Henman Hill and Derwent Floodwash.
What the work involves, part by part
School and staff canteen kitchens
Canteens and school kitchens tend to run to a timetable, so the canopy can be cleaned when the kitchen is closed. Holidays and weekends work well.
Island canopies
With filters on more than one side, an island canopy has more plenum to clean. We work round the canopy, cleaning each filter bank and plenum.
Why act early in North Cheam
A greasy canopy is fuel directly above the flame. A flare-up can catch it and be drawn into the plenum and duct, where a fire is much harder to stop. Cleaning it removes that fuel. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

What we’re called out for in North Cheam
However carefully a kitchen in North Cheam is run, the canopy still collects grease. It’s fuel, sitting directly over the burners, so a flare-up near a greasy hood can quickly become a fire.
If you notice any of these, it’s worth a diagnosis:
- Poor capture at the hood
- A greasy hood noticed by an inspector
- Condensation running down the canopy
- Grease filters blocking between washes
Term dates shape school work: for a school like Cheam Park Farm Primary Academy, an extract clean fits neatly into a half-term or summer break.
Questions to ask before booking
- Whether the whole system is included, or only the parts that are easy to reach
- Which accreditations they hold, and whether you can check them
- How they set the interval to the next visit
- When they can work, and whether that’s outside your opening hours
