About our extract fan cleaning in Hounslow
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. If you’re dealing with a noisy fan that has got louder over time and a fan left out of previous cleans, we can help.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Hounslow, 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, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Grease, kitchens and Hounslow
The Food Standards Agency lists about 14 bars, pubs and nightclubs as registered food businesses in and around Hounslow, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. London Fire Brigade covers Hounslow. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Term dates shape school work: for a school like Meadhurst Primary School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near Church of St Dunstan, or anywhere in Hounslow, may not know when the extract was last cleaned, and a grease test settles it.
Hounslow is about 1 mile north of Sunbury-on-Thames, in Greater London. Whether your site is in the middle of Hounslow or further out, extract fan cleaning is available to all kinds of commercial premises, from a single unit to a large public building. 764 places in Greater London are on our list, from busy centres to quieter spots. We also work in Guildford, around 14 miles away.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Keep the grease filters clean and in place
- Keep records of every fan clean
- Tell us if the extract feels weaker
- Look for grease stains near the discharge
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Don’t run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
The process
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes a couple of hours per fan, depending on its size and the build-up. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Hounslow.
- We find the fan and check how it’s reached and how it’s isolated.
- Power to the fan is isolated before anyone touches it.
- We remove the grease from the blades, impeller and casing.
- We degrease the fan and housing, taking care around the motor.
- It’s closed up, run and checked, and photos go into your report.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

Hounslow questions
Do you clean school canteen extracts around Hounslow out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 28 schools, colleges and universities with registered kitchens within about a mile and a half of Hounslow. Just call 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Do you work at weekends in Hounslow?
Yes. We work evenings, overnight and at weekends. It means the site in Hounslow keeps running as normal. Let us know the hours you’re closed and we will book within them.
Should the extract fan be cleaned as part of TR19?
Yes. TR19® Grease covers the whole system, fan included. We clean it alongside the canopy, ductwork and discharge.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Can the fan be cleaned between full cleans?
Yes, a fan can be cleaned on its own. That helps when the fan needs attention before the next full clean, but it doesn’t replace a full TR19 clean.
How often should the extract fan be cleaned?
It’s cleaned with the whole extract at BESA’s minimum intervals for your cooking hours. Grease readings and the fan’s condition can show it needs more.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.

What we are called out for in Hounslow
Fans that are hard to reach are often the ones that get missed. A fan that has never been cleaned can be heavily coated, and the report will show it.
If you notice any of these, it’s worth a diagnosis:
- A heavily greased fan housing
- A fan that hums, whines or rumbles
- A fan that has never been cleaned
- Weak extraction at the canopy
A hospital like Ashford Hospital, about 1.9 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Why deal with it now?
Cleaning the fan in Hounslow now is a short job: it takes an hour or two for one fan, longer when it’s hard to reach. Waiting adds vibration, wear and a harder clean. Every month a London system goes without attention adds to what has to be done later.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
