Extract fan repair for kitchens and businesses in Knatts Valley
Every fan job begins with finding the fault. Noise can come from grease on the impeller, worn bearings or a slipping belt; a dead fan can point to the motor or its controls. We explain the problem, and what it will take, before any work starts. We are often asked to deal with an extract that vibrates through the ductwork and a fan that won’t start at all, on belts and pulleys, fan housings and roof and wall fans.
In a small place like Knatts Valley, fans are often on an outside wall or roof, open to wind and rain. Weather and grease together wear out motors and bearings.
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. It shows what was done and what, if anything, couldn’t be reached.

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes anything from an hour or two to a full visit, depending on the fault. In a small place like Knatts Valley, the journey is planned ahead and the visit arranged around the site’s hours.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.
Getting ready for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or send us an email.

How we price extract fan repair
A fixed price needs a few facts first. We check:
- How big the system is
- The number of sites or systems
- Working hours and out-of-hours timing
- Site rules, permits and inductions
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What to send for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- A few general shots of the system
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or drop us a line.
When something else is needed
To be straight with you, some problems need a different fix:
- An extract system that was undersized from the start
- Faults in the building’s electrical supply, which need an electrician
- Smells from the discharge that need odour control equipment
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer before booking.

Aftercare tips
After the visit, a few habits help the work last:
- Get a noisy fan checked rather than slowed down
- Keep the emergency number where staff can see it
- Clean or change filters on schedule
- Note when the fan trips or cuts out
Where parts need ordering, we explain what that means for the kitchen until we return. The fan is completed on a return visit at a time that suits your service.
When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something 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 will take a look and send you a fixed quote.
What extract fan repair looks like in Knatts Valley
Look up Knatts Valley on the FSA’s food hygiene register and you will find about 4 restaurants, cafés and canteens in Knatts Valley and the streets around it, up to about 1.5 miles out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. About 19 miles out from central London, Knatts Valley is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Food hygiene inspections in Knatts Valley are the job of Sevenoaks council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like West Kingsdown CofE VC Primary School, fix a failing fan before term starts. A fan that rarely runs, like one in a hall kitchen near Church of Saint Mary the Virgin or elsewhere in Knatts Valley, can seize between uses.

FAQs for Knatts Valley
Will you come out to Knatts Valley?
Yes, Knatts Valley is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can you work in Knatts Valley outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Knatts Valley can fit around your hours. When you call 0345 646 2711, or email photos, mention when the site is quiet.
Can you tell me the price of a fan repair?
We price each job after finding the cause. A belt and a new fan are very different jobs, so phone us on 0345 646 2711, or email photos and we will arrange a diagnosis.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Who has the legal duty for fire safety?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
How much time does a fan repair need?
As a guide, it takes a few hours on site, depending on the fault and the access to the fan. If parts have to be ordered, we’ll tell you how long that’s likely to be.

What else we do in Knatts Valley
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building to keep disruption down.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Leave it or put it right?
Vibration does damage beyond the fan. Fixings work loose and joints in the ductwork can be strained, so a small repair can grow into a bigger one. If the system at a site near Knatts Valley fails, there may be nowhere nearby to move to.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
