Extractor fan repair in Ruislip
Repair and replacement of kitchen extract fans, fan motors and worn fan parts for businesses, landlords and public buildings in Ruislip. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- A humming noise from the fan motor
- A squealing belt on start-up
- A dead fan motor
Between visits
To keep the system working properly between visits:
- Keep the fan on a planned cleaning cycle
- Write down when the fan misbehaves
- Keep the grease filters clean and fitted
- Avoid lowering the speed to quieten a fault
Where parts need ordering, we explain what that means for the kitchen until we return. We then come back and fit them at a time that suits your service.
A fan that is starting to make noise is giving you a warning. Getting it checked now means a planned repair rather than an emergency during service.
How we handle extract fan repair in Ruislip
Think of it as a check-up for the fan: we hear the symptoms, find the cause and put it right. What you want back is a fan that runs smoothly and a plain account of what we found. If you’re dealing with poor airflow at the canopy and a whining or grinding extract motor, we can put it right.
Rooftop fans in London take the weather as well as the grease from below, and in time, bearings, belts and motors fail. A fan that’s noisy or vibrating is giving a warning.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Places near Ruislip
Also in Ruislip
Part by part
Belt-driven fans
Belt drives have more moving parts than direct-drive fans. That means more to check, but often a simpler repair.
Motors and bearings
Rumbling and grinding normally come from the bearings. We diagnose whether it’s the bearings or the motor itself and then recommend the fix.
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
How it 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 the area around the work is covered and protected. The work itself takes an hour or two to diagnose, then longer if parts or a new fan are needed. In Ruislip, 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.
- 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.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system

For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Ruislip and across Greater London. Larger estates can be phased building by building around the people who use them.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Why it’s worth doing now in Ruislip
A noisy fan rarely fixes itself. Worn bearings can seize without much warning and the fan may stop when you are busiest. A repair booked now is simpler than an emergency later. A booked night’s work in Ruislip costs you no trading time; an unplanned closure does.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Ruislip questions
Is there an emergency callout for extract fans in Ruislip?
We run a 24/7 emergency line for failed extract fans, and Ruislip is part of our area. Use 0345 646 2711, our emergency number, at any time. Details of the make and model help us plan the repair.
Do you work at weekends in Ruislip?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Ruislip needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Do you provide a certificate or report?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What makes a kitchen extract fan rattle or whine?
Grease on the blades throws the fan out of balance and that is one of the most common reasons. Worn bearings, belts and loose mounts are others.
How much time does a fan repair need?
A typical repair takes a few hours on site, depending on the fault and the access to the fan, including testing. We plan the work around your service wherever we can.
When something else is needed
Extract fan repair can’t fix everything, and we will tell you before work begins. It will not put right:
- Faults in the building’s electrical supply, which need an electrician
- Smells from the discharge that need odour control equipment
- Grease throughout the ductwork, which needs a full TR19 clean
Not sure which it is? You can call us on 0345 646 2711 or email us and we will tell you honestly before you book.

When a fan fails in Ruislip
The FSA’s food hygiene register shows about 138 restaurants, cafés and works canteens and about 70 sandwich bars and takeaways within roughly a mile and a half of the centre of Ruislip. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Food hygiene inspections in Ruislip are the job of Hillingdon council’s environmental health team. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That’s one more reason not to keep cooking with a broken fan. London extract fans are often at the end of long duct runs, on roofs or in basements.
For school kitchens, at schools like Warrender Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time. If you look after a church or hall kitchen near St Lawrence, or anywhere in Ruislip, test the extract fan before a big event rather than on the day.
