Extract fan cleaning in Knockholt Pound
Not all extract fans are the same: fans on the roof, fans built into the duct run, and fans on an outside wall. Each is isolated and opened in its own way, and we plan that during the survey. We’re often asked to deal with a heavily greased fan housing and vibration from an unbalanced impeller, across axial fans, discharge points and in-line fans.
Somewhere as small as Knockholt Pound, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Signs you need extract fan cleaning in Knockholt Pound
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.
The symptoms we’re asked about most are:
- A smell of hot grease from the extract
- A noisy fan that has got louder over time
- A fan shaking on its mounts
- Grease stains around the discharge
If you look after a school kitchen, at a school such as Halstead Community Primary School or anywhere near Knockholt Pound, the holidays are the usual time for a TR19® clean.
Before booking anyone
- Whether the price is fixed
- Whether inaccessible sections are listed on the report
- Whether they’re fully insured
- When the next visit should be, and why
What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What the work involves, part by part
Impellers and blades
While the impeller is clean, we can see its condition: chips, distortion or wear. We note any concerns.
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
What affects the quote in Knockholt Pound
The quote reflects the site in front of us. We take into account:
- How easy every part is to reach
- One-off work versus a regular cycle
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Problems your staff have spotted
- A few general shots of the system
To get a fixed quote, call 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Keep records of every fan clean
- Keep the fan on whenever the range is lit
- Keep the grease filters clean and in place
- Note any drop in extraction at the canopy
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.
Keep the route to the fan clear. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
How it works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes an hour or two for most single fans. We agree a date with you, plan the drive to Knockholt Pound and turn up when the site is quiet.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it cannot run while we work.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
Before we arrive
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site

Knockholt Pound: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Knockholt Pound?
In Knockholt Pound, it’s Sevenoaks council that carries out food hygiene inspections. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you work at weekends in Knockholt Pound?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Knockholt Pound needn’t be disturbed. Your opening times are the first thing we ask for.
Do you need to turn the fan off to clean it?
The fan is isolated before we open it, so it cannot start while we work. With the extract off, the kitchen cannot cook, so we work out of hours.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
How much does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.
Is there a survey before the work?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.

Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. In Knockholt Pound, food businesses are inspected by environmental health officers from Sevenoaks council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
