Canopy cleaning for kitchens and businesses in Old Chiswick
For canopies and hoods in Old Chiswick, the work follows the same careful routine: filters out, plenum scraped and degreased, then the canopy cleaned inside and out. Before and after pictures go into your report. If you are dealing with a sticky, discoloured canopy and grease channels that no longer drain, we can put it right, from canopy light fittings, baffle filters and wall canopies onwards.
In a London area like Old Chiswick, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
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 carry full insurance.

Grease, kitchens and Old Chiswick
Look up Old Chiswick on the FSA’s food hygiene register and you will find about 474 restaurants, cafés and works canteens and about 94 sandwich bars and takeaways within 1.5 miles or so of the middle of Old Chiswick. Where they cook under a hood, the plenum behind the filters is where grease hides. Old Chiswick 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. Most London extract cleaning happens at night, after the last service.
Volunteers running a hall kitchen near St. Nicholas Church, or anywhere in Old Chiswick, may not know when the extract was last cleaned, and a grease test settles it. If you run catering at a healthcare site, such as a hospital like West London Hospital about 1.3 miles east, the extract may need cleaning more often than a part-time kitchen.

Managing agents and facilities teams in Old Chiswick
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Before any visit in Old Chiswick, we agree where the van can stop and how equipment reaches the system.
- We start by checking the canopy and what’s behind its filters.
- Equipment is turned off and cooled, and the area under the canopy is protected.
- Heavy deposits come off by hand, then the surfaces are degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after pictures and a next clean date.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Let us know when the site is closed or quiet
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or email us.
Advice
What the work involves, part by part
Island canopies
The underside of an island canopy is in full view so a clean, even finish matters. We degrease it thoroughly and photograph the result.
Grease troughs and gutters
Where a trough drains into a grease cup, we empty and clean that as well, and we will show staff where it is.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What happens if it’s left?
A canopy clean in Old Chiswick now stops the grease spreading further. It takes an hour or two for one small canopy, longer where there are several, out of hours so service carries on. Put off, the grease simply moves further into the system. A busy site in Old Chiswick builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

FAQs for Old Chiswick
Do you work at weekends in Old Chiswick?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
Does London parking affect a job in Old Chiswick?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
What does TR19 mean?
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.
Is canopy cleaning enough for TR19?
A canopy-only clean is possible, but it isn’t a full TR19 clean. For TR19, the whole system needs cleaning, at intervals set by BESA guidance.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What affects the cost of canopy cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- The times the site is available
- How easy every part is to reach
- How many systems or sites are involved
- Parking and loading at the site
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
To speed up the quote, please include:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Problems your staff have spotted
- Any access panels or hatches you can see
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then call 0345 646 2711 or email us.
Common problems we fix in Old Chiswick
However carefully a kitchen in Old Chiswick is run, the canopy still collects grease. That grease is fuel sitting right above the heat, which is why a flare-up near a dirty canopy is so dangerous.
Any of these means the system needs a check-up:
- A sticky, discoloured canopy
- Overflowing grease troughs and gutters
- Poor capture at the hood
- Condensation running down the canopy
A kitchen near Chiswick station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
