Extract Fan Cleaning in Throcking
Extract fan cleaning for commercial sites in Throcking and across Hertfordshire. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Burning smells from the fan area
- Less air being pulled from the kitchen
- A motor area thick with grease
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
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.
Extract fan cleaning for kitchens and businesses in Throcking
In Throcking, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. Your report shows the impeller as we found it and as we left it. The work covers centrifugal fans, roof-mounted fans and discharge points, and people most often call us about grease stains around the discharge and a fan coated in grease inside its housing.
Somewhere as small as Throcking, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Your questions about extract fan cleaning in Throcking
Can a school canteen extract in Throcking be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Throcking. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is Throcking within the area you cover?
Yes. Throcking is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What paperwork do I get after a fan clean?
Before and after photos go into a report, with anything we noticed. For a full TR19 clean, you also get a certificate through the BESCA Vent Hygiene Elite portal.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do we need to close while you work?
Not normally. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How often does the fan need cleaning?
It depends on how many hours the kitchen cooks, under BESA guidance. At the extremes, that is 3-monthly for heavy use and 12-monthly for light use, fan included.
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.
What extract fan cleaning can’t fix
Before booking, it helps to know what’s not included:
- An impeller that’s bent or split
- A fan that was never right for the kitchen
- A motor that has burnt out
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we’ll tell you honestly.
Where we work
- Roof-mounted fans
- Axial fans
- Discharge points
- In-line fans
- Centrifugal fans
- Fan housings
When to call us in Throcking
By the time air reaches the fan, it has passed the canopy, filters and duct. The grease that’s left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
If you notice any of these, it’s worth a diagnosis:
- A heavily greased fan housing
- Burning smells from the fan area
- A noisy fan that has got louder over time
- A fan that no longer moves enough air
Bursars and site managers at schools such as Freman College tend to book extract cleaning for when the kitchen is empty.

What else we do in Throcking
Leave it or put it right?
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Planning a trip to Throcking ahead is easier for everyone than a rushed one.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Part by part
Inline duct fans
Inline fans can be in tight spaces, so the method is planned in advance. If it cannot be reached fully, the report says so.
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, which means grease and wear add up quickly. Regular cleans help it keep going.
