About our extract fan cleaning in St Johns
A fan never collects grease in a neat, even layer. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. Common call-outs are for fat spreading onto the roof or wall by the fan and hot, greasy smells near the fan, across fan housings, roof-mounted fans and discharge points.
In a London area like St Johns, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
We’ve 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 carry full insurance.

The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two for one fan, longer when it’s hard to reach. Loading bays, visitor permits and roof access are the first things we ask about for a site in St Johns.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and pictures go into your report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Arrange a key holder or contact on site

Related advice
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Your questions about extract fan cleaning in St Johns
Which council inspects kitchens in St Johns?
Food hygiene inspections in St Johns are carried out by Greenwich council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you come to St Johns after we close?
Yes, nights and weekends are routine for us. It means the site in St Johns keeps running as normal. Your opening times are the first thing we ask for.
Is the fan included in a TR19 clean?
Yes, the fan is cleaned as part of TR19. Anything that cannot be reached is recorded, so you always know what was cleaned.
Can the fan be cleaned between full cleans?
Yes, we do. The report will make clear that only the fan was cleaned, so your TR19 records stay accurate. The whole system still needs cleaning at the intervals in BESA guidance.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Why is my extract fan noisy?
Uneven grease on the impeller often causes it. After cleaning, we’ll tell you if wear or damage is also involved.
How long will it take to clean the fan?
Size, access and build-up all affect it. Typically it takes a couple of hours per fan, depending on its size and the build-up.
What does extract fan cleaning cost?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Between visits
Aftercare is simple, and it makes the next visit easier:
- Keep each photo report with the maintenance log
- Look for grease stains near the discharge
- Leave a clear route to the fan
- Keep the grease filters clean and in place
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Don’t run the kitchen with the extract off. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
What extract fan cleaning can’t fix
To be straight with you, some problems need a different fix:
- A fan that was never right for the kitchen
- A failed motor or worn bearings (that needs a fan repair or replacement)
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
If you are not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer.

Do you need extract fan cleaning in St Johns?
A fan on a roof or hidden in a ceiling void is easy to forget. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
It’s time to book a visit if you see:
- A smell of hot grease from the extract
- Grease stains around the discharge
- A motor area thick with grease
- Vibration from an unbalanced impeller
A hospital like Miller General Hospital, about under half a mile north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

St Johns kitchens: local notes
The FSA’s food hygiene register shows about 452 cafés, restaurants and staff canteens and about 224 takeaways and sandwich shops in St Johns and the streets around it, up to about 1.5 miles out. The fan at the end of each of those extracts collects grease that slows it and wears the motor. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. The fire and rescue service for St Johns is London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run a church or community hall kitchen, near Church of St John or elsewhere in St Johns, its extract still collects grease from every lunch and event. A kitchen near St Johns station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Different parts, different methods
Impellers and blades
The blades of the impeller do the work, and grease builds up on them unevenly. That is what unbalances the fan, so it’s cleaned carefully blade by blade.
Fan housings and motors
Some fans use a belt drive. We clean around them and note any wear for your records.
