How we handle extract fan repair in New Barnet
A faulty fan doesn’t always mean a new one. Often a clean, a new belt or new bearings brings it back, and that is what we’ll recommend. When a fan is worn beyond sensible repair, a replacement suited to the system goes in. The work covers kitchen extract fans, belts and pulleys and fan housings, and people most often call us about an extract fan that rattles or knocks and a worn or slipping fan belt.
Replacing a fan in a London building often means working at height or in a tight plant space, with parking and lifting to arrange in New Barnet. Work can be done after service, so the kitchen loses as little time as possible.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Extract fan repair around New Barnet
The FSA’s food hygiene register shows about 116 restaurants, cafés and canteens and about 40 sandwich bars and takeaways within 1.5 miles or so of the middle of New Barnet. Those that cook under a canopy rely on a fan that runs every hour they’re open. Food hygiene inspections in New Barnet are the job of Barnet council’s environmental health team. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. A kitchen without a working fan has a problem to fix quickly. We ask about access first for a London fan job, because roofs and basements need planning.
For school kitchens, at schools like St Mary's CofE Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time. If you run a kitchen close to New Barnet station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

Questions from New Barnet
Can you come to New Barnet after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in New Barnet keeps running as normal. Tell us your opening hours when you ask for a quote.
Does London parking affect a job in New Barnet?
A loading bay, a visitor permit or off-street space near the site in New Barnet makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
Do you replace extract fans as well as repair them?
Yes, when repair does not make sense. The replacement has to suit the ductwork and the cooking before recommending a unit.
Should the fan be cleaned as well as repaired?
The ductwork is a separate job. We will point out grease where we find it, so you can decide whether to book a TR19 clean.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
When to call us in New Barnet
Fan bearings do not last for ever, especially in a hot, greasy airstream. Worn bearings whine, rumble or grind, and if they’re left they can seize.
The symptoms we are asked about most include:
- A knocking noise from the extract fan
- A fan that whines, hums or grinds
- A belt-driven fan that squeals
- A dead fan motor
Occasional-use kitchens, such as a hall kitchen near Holy Trinity Lyonsdown or elsewhere in New Barnet, are where a stiff or seized fan can turn up.

What else we do in New Barnet
What the work involves, part by part
Direct-drive fans
Direct-drive fans have the impeller mounted straight on the motor. There are no belts, so faults tend to be in the motor, bearings or impeller.
Motors and bearings
Motors and bearings take the most strain in a kitchen extract fan. Hot, greasy air and long days wear them down.
Managing agents and facilities teams in New Barnet
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a few hours for most repairs, longer for a full fan replacement. If your building in New Barnet has sign-in rules, permits or key holders, mention them when you book.
- We agree a time to attend, out of hours if needed.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
Getting ready for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Why it’s worth doing now in New Barnet
A noisy fan rarely fixes itself. Worn bearings can seize without much warning and the fan may stop when you’re busiest. A repair booked now is simpler than an emergency later. In New Barnet, as across London, ductwork often passes through shared risers and other people’s space.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or email us for straight advice and a fixed quote.
