Extract Fan Repair in Whetstone
Repair and replacement of kitchen extract fans, fan motors and worn fan parts for commercial sites in Whetstone and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- A worn or slipping fan belt
- A whining or grinding extract motor
- Vibration spreading from the fan into the ducts
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Make sure the fan is cleaned with the rest of the system
- Keep the emergency number where staff can see it
- Tell us about a new rattle or whine right away
- Don’t cook with gaps in the filter bank
Your kitchen can get back to normal as soon as the fan is running. We leave the area tidy and talk you through what we found.
When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.
About our extract fan repair in Whetstone
Our engineers handle all sorts of fan faults in Whetstone, from rattling and humming to a fan that has stopped dead. We find the cause, give you a fixed price and fix it, or the fan is replaced if repair doesn’t make sense. If you are dealing with vibration spreading from the fan into the ducts and a humming noise from the fan motor, we can help, from fan motors, fan housings and bearings onwards.
For a London kitchen, a failed extract fan usually means the cooking stops. In Whetstone, as across London, fans often sit on a roof or deep in a plant space, so we ask about access first.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Direct-drive fans
Grease on the impeller unbalances a direct-drive fan quickly. Sometimes a clean is all it needs, if the bearings haven’t been damaged.
Impellers and housings
Where an impeller is bent or corroded, cleaning won’t help. It may need replacing, or the fan may need replacing as a whole.
Honest limits
Some problems need a different service or another trade:
- Faults in the building’s electrical supply, which need an electrician
- A greasy canopy and duct that a fan repair won’t touch
- Smells from the discharge that need odour control equipment
If you are not sure, just call 0345 646 2711, or email photos and we will give you a straight answer before booking.
Where we work
- Belts and pulleys
- Bearings
- Roof and wall fans
- Kitchen extract fans
- Fan housings

Your questions about extract fan repair in Whetstone
Which council inspects kitchens in Whetstone?
Food hygiene inspections in Whetstone are carried out by Barnet council. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Can the work in Whetstone be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Whetstone does not have to lose a day’s trading. Your opening times are the first thing we ask for.
How long does an extract fan repair take?
Typically, a fan repair takes a few hours for most repairs, longer for a full fan replacement. Where parts need ordering, we will explain the timescale.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Do you work in Whetstone?
Yes. Whetstone is part of the area we cover, as part of our area across London and the South East.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What affects the quote in Whetstone
We quote each job individually. These are the things that affect it:
- Working hours and out-of-hours timing
- A single visit or a regular plan
- The condition of the system
- Travel, parking and unloading
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
If you need extract fan repair in Whetstone, phone us on 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote normally follows within one working day.
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes anything from an hour or two to a full visit, depending on the fault. Security desks and permits-to-work are routine in London, so let us know what your building in Whetstone needs from us.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
- Tell us where we can park and unload
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Extract fans in Whetstone
The FSA’s food hygiene register shows about 139 restaurants, cafés and canteens and about 52 sandwich bars and takeaways within roughly a mile and a half of the centre of Whetstone. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Kitchens in Whetstone get their food hygiene inspections from Barnet council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That is one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
If you manage a school such as Queenswell Infant & Nursery School and the kitchen fan is getting louder, the next break is the time to deal with it. If you run a kitchen close to Oakleigh Park station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. Occasional-use kitchens, such as a hall kitchen near Church of St John or elsewhere in Whetstone, are where a stiff or seized fan can turn up.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
If your staff spot something 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 can diagnose it and quote.
