Greater London · Extract fan repair and replacement
Finchley extract fan repair
Professional extract fan repair in and around Finchley, booked around your opening hours and finished with a written report and pictures.
- An extract fan that rattles or knocks
- A fan that won’t start at all
- A whining or grinding extract motor
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep a record of any trips or stoppages
- Keep the fan on a planned cleaning cycle
- Clean or change filters on schedule
- Keep the emergency number where staff can see it
Your kitchen can get back to normal as soon as the fan is running. We clear up after ourselves and explain anything you need to know.
Noise is normally the first sign of a fan problem. Getting it checked now means a planned repair instead of a breakdown at the worst moment.
About our extract fan repair in Finchley
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. You hear what we’ve found before any work goes ahead. We are often asked to deal with an extract fan that rattles or knocks and a fan shaking on its mountings, on belts and pulleys, fan motors and roof and wall fans.
In London, getting a new fan to the roof or plant room can take planning, with parking and lifting to arrange in Finchley. Work can be done after service, so the kitchen loses as little time as possible.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Different parts, different methods
Direct-drive fans
Direct-drive fans have the impeller mounted straight on the motor. With no belts to wear, we look at the motor, bearings and impeller.
Fan controls
We check the controls as part of every diagnosis since the motor is not always to blame.
How the visit works
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 photos. The middle part takes longest, and that takes part of a day for most faults, with a return visit if parts have to be ordered. A name and number for whoever controls access to the building in Finchley saves time on the night.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- The fan is repaired or replaced, then checked running.
Preparing for the visit
- Move anything stored near the system
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what extract fan repair will not do:
- A system that needs redesigning rather than repairing
- Faults in the building’s electrical supply, which need an electrician
- Cooking smells reaching neighbours, which may need odour control
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think.
What the work covers
- Belts and pulleys
- Kitchen extract fans
- Fan housings
- Fan motors
- Bearings

Signs you need extract fan repair in Finchley
Blocked filters and greasy ducts make the fan work harder. A motor that strains runs hot, trips out or eventually burns out.
Most sites get in touch after spotting one of these:
- An old fan that needs replacing
- Vibration spreading from the fan into the ducts
- A squealing belt on start-up
- A fan that whines, hums or grinds
If you manage a school such as Manorside Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.
What your quote should include
- When the next visit should be, and why
- Whether VAT is included
- Exactly which parts of the system are covered
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Finchley: your questions answered
Can you work in Finchley outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Finchley keeps running as normal. Your opening times are the first thing we ask for.
Can you come out to a failed extract fan in Finchley out of hours?
Day or night, a failed fan in Finchley can be reported on our emergency line. Ring 0345 646 2711 at any hour and describe the fault. A photo of the fan’s rating plate helps.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Can you supply and fit a replacement fan?
Yes, when repair does not make sense. We check the duct size and the extract the kitchen needs so we confirm that first.
What causes a noisy extract fan?
An unbalanced, greasy impeller vibrates and that is one of the most common reasons. Worn bearings, belts and loose mounts are others.
What paperwork should we keep on file?
Anything that proves the system is maintained: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How long will the fan be out of action?
It depends on the fault, but as a guide it takes anything from an hour or two to a full visit, depending on the fault. We’ll give you a better idea once we have diagnosed it.
When a fan fails in Finchley
There are about 180 restaurants, cafés and works canteens and about 55 takeaways and sandwich shops within about 1.5 miles of central Finchley, according to the Food Standards Agency’s register. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Kitchens in Finchley get their food hygiene inspections from Barnet council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That makes a fan repair urgent rather than something to put off. London extract fans are often at the end of long duct runs, on roofs or in basements.
If you look after a church or hall kitchen near St Paul's Finchley, or anywhere in Finchley, test the extract fan before a big event rather than on the day.

Managing agents and facilities teams in Finchley
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Why deal with it now?
An overloaded motor is under constant strain. That shortens its life, and when it finally fails, it may take other parts with it. Early attention keeps the cost and disruption down. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
