For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in East Finchley and across Greater London. Work can be phased by floor, building or site around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
About our extract fan repair in East Finchley
Before anything is ordered, we diagnose. The motor, drive, impeller, bearings and mounts are all checked, along with the fan’s controls. Then you’re given a fixed quote for the repair or the replacement. If you have a failed fan that needs a replacement and a motor that trips out or overheats, we can put it right.
In London, a kitchen without working extraction cannot keep cooking safely. In East Finchley, as across London, fans often sit on a roof or deep in a plant space, so we ask about access first.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes an hour or two to diagnose, then longer if parts or a new fan are needed. In a London area like East Finchley, parking, loading and building access are planned before the day of the work.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- The fan is isolated and opened up so we can see inside.
- We check the motor, bearings, drive, impeller and mountings.
- You get our diagnosis and a fixed quote to repair or replace.
- We fix or replace the fan, then test it running before we leave.
How to prepare
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in

Fixed quotes for extract fan repair in East Finchley
We quote each job individually. This is what makes a difference:
- How big the system is
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
Helping us quote
You do not need the technical terms. Just send:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- Your last certificate, test record or report
For a fixed quote, ring 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Different parts, different methods
Motors and bearings
An overheating motor is a warning sign. The cause might be grease restricting the airflow, or the motor itself may be failing.
Fan controls
Controls are checked as well as the fan itself, because a fan that will not start is not always a failed motor.
Why act early in East Finchley
A fan that is running slowly is not clearing the kitchen properly. Staff work in hotter, steamier air and grease has more chance to settle on surfaces and in the duct. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

What else we do in East Finchley
Extract fans in East Finchley
Food Standards Agency data counts about 190 restaurants, cafés and canteens and about 46 takeaways within about 1.5 miles of central East Finchley. Those that cook under a canopy rely on a fan that runs every hour they’re open. In East Finchley, food businesses are inspected by environmental health officers from Barnet council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. A kitchen without a working fan has a problem to fix quickly. London extract fans are often at the end of long duct runs, on roofs or in basements.
Occasional-use kitchens, such as a hall kitchen near Church of the Holy Trinity or elsewhere in East Finchley, are where a stiff or seized fan can turn up. If you manage a school such as Holy Trinity CofE Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.

What extract fan repair cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Grease throughout the ductwork, which needs a full TR19 clean
- Ductwork designed too small for the kitchen’s cooking
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.

East Finchley: your questions answered
Does London parking affect a job in East Finchley?
A loading bay, a visitor permit or off-street space near the site in East Finchley makes the visit easier to plan. Much of our London work is done overnight, which helps.
Which council inspects kitchens in East Finchley?
That’s Barnet council, whose environmental health officers carry out food hygiene inspections in East Finchley. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Do we need to close the kitchen for fan work?
While we’re working on the fan, the extract is isolated. We can come when the kitchen is closed so service carries on as normal.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Can you repair a fan rather than replace it?
That depends on what we find. We diagnose first and tell you whether a repair is realistic and quote a fixed price for the option you choose.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How much time does a fan repair need?
As a guide, it takes anything from an hour or two to a full visit, depending on the fault. If parts have to be ordered, we’ll tell you how long that is likely to be.
