How we handle extract fan cleaning in South Ruislip
Every TR19® Grease clean includes the extract fan, but a fan can also need attention on its own, especially when it has started to vibrate or sound rough. Where only the fan is cleaned, the report says so. Typical jobs include grease escaping from the fan outlet and a fan coated in grease inside its housing, on axial fans, roof-mounted fans and in-line fans.
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 South Ruislip, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common problems we fix in South Ruislip
A fan collects more grease when the filters let more through. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
Most sites get in touch after spotting something like this:
- An extract fan that vibrates or rattles
- A motor area thick with grease
- Less air being pulled from the kitchen
- A noisy fan that has got louder over time
Where a hall near Church of St Mary, or anywhere in South Ruislip, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before you book anyone
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or pictures
- If the quote is a fixed price or an estimate
- Whether the whole system is included, or only the parts that are easy to reach
How we price extract fan cleaning
Before we fix a price, we need to know a few things. We look at:
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Wide photos of the system and the area around it
- Problems your staff have spotted
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. Add the site type and your opening hours, and many jobs can be priced from that alone.
Multi-site and managed buildings
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 can quote for the whole system.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a few hours where there are several fans or heavy deposits. Night and weekend working is normal for us in London, and a site in South Ruislip is no exception.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Tell us where we can park and unload
- Move anything stored near the system
- Arrange a key holder or contact on site

What a clean won’t put right
Some problems need a different service or another trade:
- A failed motor or worn bearings (that needs a fan repair or replacement)
- An undersized fan that cannot cope
- A faulty speed controller or isolator
Not sure which it is? You can call us on 0345 646 2711, or email photos and we’ll tell you honestly.

Grease, kitchens and South Ruislip
Food Standards Agency records include about 18 bars, pubs and nightclubs across South Ruislip 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. Kitchens in South Ruislip get their food hygiene inspections from Hillingdon council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Most London extract cleaning happens at night, after the last service.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to South Ruislip is Clementine Churchill Hospital, about 2.7 miles east. A kitchen near South Ruislip station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

How the job changes from site to site
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. The survey makes sure it’s part of the clean.
Wall fans
With little duct before them, wall fans collect grease fast. They can need regular attention, which grease readings will show.
South Ruislip: your questions answered
Do you work overnight in South Ruislip?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
Who enforces fire safety at workplaces in South Ruislip?
London Fire Brigade is the fire and rescue service for South Ruislip. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Is it safe to clean the fan while the kitchen is open?
The fan must be isolated, for safety. Cleans are done when the kitchen is closed, so cooking is not affected.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Are you accredited?
Duct Doctor is 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.
What makes a kitchen extract fan vibrate?
An unbalanced impeller, normally from uneven grease, is a common cause. We clean the fan and tell you if anything else, like worn bearings, is to blame.
How long is a fan clean?
That depends on the fan’s size, its position and how much grease there is. Typically it takes an hour or two for one fan, longer when it’s hard to reach.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

Why it’s worth doing now in South Ruislip
Cleaning the fan in South Ruislip now is a short job: it takes a couple of hours per fan, depending on its size and the build-up. Waiting adds vibration, wear and a harder clean. A building in South Ruislip may have flats or offices above and alongside, and a fault in the system can affect them too.
