What we are called out for in Cockfosters
Bearings wear out with heat and long hours. Worn bearings whine, rumble or grind and a seized bearing stops the fan.
Clients typically contact us after spotting something like this:
- A squealing belt on start-up
- A knocking noise from the extract fan
- A whining or grinding extract motor
- An extract fan that has stopped working
If you manage a school such as Trent CofE Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.
Before booking anyone

How we handle extract fan repair in Cockfosters
Grease and fans don’t mix. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. So when we repair extract fan, we look at the grease too, and a full TR19® clean can be booked alongside. If you have a belt-driven fan that squeals and a fan shaking on its mountings, we can put it right, from roof and wall fans, fan housings and bearings onwards.
Rooftop fans in London take the weather as well as the grease from below, and in time, bearings, belts and motors fail. A fan that is noisy or vibrating is giving a warning.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Do not cook with gaps in the filter bank
- Write down when the fan misbehaves
- Get a noisy fan checked rather than slowed down
- Keep the area around the fan controls clear
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.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and wear is caught earlier.
How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes an hour or two to diagnose, then longer if parts or a new fan are needed. Night and weekend working is normal for us in London, and a site in Cockfosters is no exception.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
Getting ready for the visit
- Arrange a key holder or contact on site
- Let us know about permits to work or site inductions
- Mention any locked doors, roof access or ceiling voids

Common questions in Cockfosters
What if my kitchen extract fan stops in Cockfosters at night?
Cockfosters is covered, and our emergency callout runs 24/7. Ring 0345 646 2711 at any hour and describe the fault. Details of the make and model help us plan the repair.
Is parking a problem for work in Cockfosters?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Will we have to shut during the visit?
Typically not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Why is our extract fan so noisy?
There are several possible causes, from a worn bearing to a loose fixing. It’s worth having it diagnosed before the fault gets worse.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
Why deal with it now?
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Even without an interlock, cooking without extraction isn’t sensible, so a failing fan is worth dealing with early. Leaving it on a busy London site only adds to the work.
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or email us, and we will explain what it covers.

What the work involves, part by part
Motors and bearings
Motors and bearings take the most strain in a kitchen extract fan. Heat, grease and long running hours all wear them.
Direct-drive fans
Direct-drive fans are compact and common in kitchen extracts. If the motor has gone, a replacement unit is often the sensible option and we will talk you through it.
When a fan fails in Cockfosters
Food Standards Agency data counts about 71 cafés, restaurants and staff canteens and about 29 takeaways within roughly a mile and a half of the centre of Cockfosters. Wherever they cook under a canopy, a failed extract fan stops the kitchen. London extract fans are often at the end of long duct runs, on roofs or in basements. In Cockfosters, food businesses are inspected by environmental health officers from Enfield council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. A kitchen without a working fan has a problem to fix quickly.
If you cook near New Barnet station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. Occasional-use kitchens, such as a hall kitchen near Christ Church or elsewhere in Cockfosters, are where a stiff or seized fan can turn up.
