Extract fan repair for kitchens and businesses in Barnet
Before anything is ordered, we diagnose. The motor, drive, impeller, bearings and mounts are all checked and the speed control too. After that, you get a fixed price for what’s needed. The work covers fan housings, fan motors and kitchen extract fans, and people most often call us about a squealing belt on start-up and a fan running too slowly to clear the kitchen.
In London, a kitchen without working extraction can’t keep cooking safely, and a closed kitchen loses a night’s trade. Fans in Barnet are often on a roof or in a basement at the end of a long duct run, so access is the first thing we ask about.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Different parts, different methods
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease on it throws it out of balance and cause vibration.
Fan controls
Supply faults are a job for an electrician. If that is the cause, we will say so so you know who to call.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Get a noisy fan checked rather than slowed down
- Make sure every filter is in place and clean
- Tell us about a new rattle or whine right away
- Keep all filters fitted while cooking
Clean filters help a repaired fan stay that way. Less grease on the impeller means less wear and fewer faults.
Regular TR19 cleaning includes the extract fan. A clean impeller stays in balance, so planned cleaning helps the fan last.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what extract fan repair won’t do:
- Problems with the electrical supply to the fan (an electrician’s job)
- Cooking smells reaching neighbours, which may need odour control
- A system that needs redesigning rather than repairing
If in doubt, ring 0345 646 2711 or drop us a line and we’ll say what we think before booking.
What the work covers
- Kitchen extract fans
- Belts and pulleys
- Bearings
- Roof and wall fans
- Fan motors
- Fan housings
When to call us in Barnet
Grease that gets past the filters ends up on the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and starts to vibrate and rattle.
Common reasons sites call us include:
- Poor airflow at the canopy
- A humming noise from the fan motor
- A failed fan that needs a replacement
- A fan shaking on its mountings
Hall kitchens near St John's United Reformed Church, or anywhere around Barnet, often use their fans only now and then, and an idle fan can stick.
Questions to ask before booking
- If they look at the system before pricing
- If the quote is a fixed price or an estimate
- What paperwork you get at the end
- Whether they recommend a next date
Barnet: your questions answered
Can you come out to a failed extract fan in Barnet out of hours?
Our emergency line runs 24/7, and Barnet is within the area we cover. Ring 0345 646 2711 at any hour and describe the fault. Details of the make and model help us plan the repair.
Can you work in Barnet outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Barnet doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
What should go in our maintenance log?
Anything that proves the system is maintained: our reports and photos, any certificates and your in-house logs. A single log for each site works best.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Can you supply and fit a replacement fan?
Yes, when repair doesn’t make sense. The replacement has to suit the ductwork and the cooking so we confirm that first.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
What’s TR19?
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, while TR19® Air covers other supply and extract ductwork.
Do we need to close while you work?
Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes anything from an hour or two to a full visit, depending on the fault, and we clear up before we go. In Barnet, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- 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.
- We check the motor, bearings, drive, impeller and mountings.
- We explain the fault and give you a fixed price for the fix.
- We fix or replace the fan, then test it running before we leave.
Preparing for the visit
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Let us know about parking and loading
Get a fixed 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.
Advice
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Extract fan repair around Barnet
Look up Barnet on the FSA’s food hygiene register and you’ll find about 109 restaurants, cafés and works canteens and about 43 takeaways and sandwich shops within 1.5 miles or so of the middle of Barnet. Wherever they cook under a canopy, a failed extract fan stops the kitchen. In Barnet, food businesses are inspected by environmental health officers from Barnet council. 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 a takeaway near New Barnet station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7. Holidays are the time to replace a tired kitchen fan at schools such as Grasvenor Avenue Infant School, rather than mid-term.
