Extract Fan Cleaning in Longfield Hill

- Grease escaping from the fan outlet
- A fan that has never been cleaned
- A fan motor running hot under a coat of grease
What happens if it’s left?
The fan is part of the fire path. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Out of sight is the usual reason a rural system goes too long without attention.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

Extract fan cleaning in Longfield Hill
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. The work covers discharge points, roof-mounted fans and in-line fans, and the jobs we see most are vibration from an unbalanced impeller and a fan left out of previous cleans.
In a small place like Longfield Hill, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We’re CHAS and SafeContractor accredited, we hold 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.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Book the fan into every full TR19 clean
- Don’t turn the fan off mid-service
- Keep each photo report with the maintenance log
- Keep the grease filters clean and in place
Where the fan needs repair rather than cleaning, the report says so. Fan repair and replacement are services we offer too, so you have one point of contact.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
What the work involves, part by part
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.
Fan housings and motors
Belt-driven fans have a drive belt and pulleys that can collect grease. We clean around them and note any wear for your records.
What we are called out for in Longfield Hill
A greasy fan in Longfield Hill is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
These are the problems we see most often:
- A fan that no longer moves enough air
- A motor area thick with grease
- Rough running from the extract fan
- Grease escaping from the fan outlet
If your kitchen is in a listed or historic building, like the houses around Longfield Hill (Cobham College is about 2.8 miles east), fitting access panels needs care.

Honest limits
To be straight with you, some problems need a different fix:
- Wiring faults to the fan
- Grease in the canopy and ductwork
- A failed motor or worn bearings (that needs a fan repair or replacement)

Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
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.
Questions from Longfield Hill
Do you cover smaller places like Longfield Hill?
Yes. Longfield Hill is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you work overnight in Longfield Hill?
Yes, out-of-hours work is a big part of what we do. It means the site in Longfield Hill keeps running as normal. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
What’s the cleaning interval for an extract fan?
Daily cooking hours set the minimum in BESA guidance. At the extremes, that is 3-monthly for heavy use and 12-monthly for light use, fan included.
Does a TR19 kitchen extract clean cover the fan?
Yes. The whole system is cleaned, from the canopy to the discharge, and the fan is a key part of it, so it’s cleaned too.
Will we have to shut during the visit?
Not normally. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Are you accredited?
We hold 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.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.

The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a couple of hours per fan, depending on its size and the build-up, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Longfield Hill.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it can’t start while we work.
- We remove the grease from the blades, impeller and casing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
- Let us know about parking and loading
