About our extract fan repair in Hornsey
Working on a fan in Hornsey means switching the extract off first, so the job is fitted around the kitchen’s hours. Evenings, overnight and weekends are all possible and there’s a 24/7 emergency line if the fan fails while you’re cooking. The work covers kitchen extract fans, belts and pulleys and fan motors, and common reasons people get in touch are a fan that whines, hums or grinds and an extract fan that rattles or knocks.
For a London kitchen, a failed extract fan usually means the cooking stops, and a closed kitchen loses a night’s trade. In Hornsey, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Why it’s worth doing now in Hornsey
In kitchens with an interlocked gas supply, no extract can mean no cooking. Without extraction, the heat and fumes build up fast and fixing the fan early avoids a forced shutdown. In Hornsey, a planned overnight visit is much easier than closing unexpectedly.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Note when the fan trips or cuts out
- Keep the fan on a planned cleaning cycle
- Avoid lowering the speed to quieten a fault
- Tell us about a new rattle or whine right away
Once we are done, the extract is back in service. We clear up after ourselves and talk you through what we found.
The fan is part of every full TR19 clean. Keeping grease off the impeller is one of the simplest ways to protect it and that means less wear.
When to call us in Hornsey
Not every problem is mechanical. Speed controllers, isolators and wiring can all fail, and a fan that will not start isn’t always a dead motor.
The symptoms we are asked about most are:
- A fan rattling in its housing
- A fan that whines, hums or grinds
- Weak extraction and a smoky kitchen
- A squealing belt on start-up
For a takeaway near Hornsey station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.

Your questions about extract fan repair in Hornsey
Can you come out to a failed extract fan in Hornsey out of hours?
Extract fan emergencies in Hornsey are covered around the clock. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Tell us where the fan is and how to reach it.
Do you work overnight in Hornsey?
Yes, evening, overnight and weekend work is normal for us. That way a site in Hornsey does not have to lose a day’s trading. Your opening times are the first thing we ask for.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What will a fan repair or replacement cost?
Every fan job is priced once we know the fault. Repair, parts or a full replacement all cost differently, so phone us on 0345 646 2711 or email us and we will arrange a diagnosis.
Is it worth cleaning the extract while you are fixing the fan?
The ductwork is a separate job. We’ll point out grease where we find it and quote for a TR19 clean if it’s needed.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you provide a certificate or report?
Yes. You get a written report with photos after each visit, showing what was done, anything we couldn’t reach and when the next visit is due. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
What affects the quote in Hornsey
The diagnosis comes before the price. We look at:
- The size of the system
- The number of sites or systems
- A single visit or a regular plan
- Whether we need access equipment or extra panels
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. Ask for a fixed quote and we will go through it with you.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Problems your staff have spotted
- A few general shots of the system
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

What else we do in Hornsey
Extract fan repair around Hornsey
Look up Hornsey on the FSA’s food hygiene register and you’ll find about 434 restaurants, cafés and canteens and about 129 takeaways and sandwich shops in and around Hornsey, up to about a mile and a half out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange. Kitchens in Hornsey get their food hygiene inspections from Haringey council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan.
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 church or community hall kitchen, near Church of Holy Innocents or elsewhere in Hornsey, an extract fan that rarely runs can seize or fail when it’s needed.

Part by part
Impellers and housings
A damaged or corroded impeller can’t simply be cleaned. It may need replacing, or the fan may need replacing as a whole.
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Worn belts squeal and slow the fan down, so we check the pulleys and bearings as well.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes part of a day for most faults, with a return visit if parts have to be ordered. In Hornsey, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- A visit is booked, in the evening or overnight if that suits.
- The extract is switched off and the fan opened up.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
Getting a quote
We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or send us an email.
