Extractor fan repair in South Harrow
Repair and replacement of kitchen extract fans, fan motors and worn fan parts for commercial sites in South Harrow and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- An extract that vibrates through the ductwork
- A worn or slipping fan belt
- An extract fan that has stopped working
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
About our extract fan repair in South Harrow
Not every failed fan needs replacing. Often a clean, a new belt or new bearings brings it back, and that is what we will recommend. When a fan is worn beyond sensible repair, a replacement suited to the system goes in. The work covers belts and pulleys, bearings and kitchen extract fans, and people most often call us about a knocking noise from the extract fan and an old fan that needs replacing.
In London, getting a new fan to the roof or plant room can take planning, and in South Harrow, parking and lifting are part of that. Work can be done after service, so the kitchen loses as little time as possible.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Security desks and permits-to-work are routine in London, so let us know what your building in South Harrow needs from us.
- 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.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
Getting 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. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
How the job changes from site to site
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.
Impellers and housings
The fan housing collects grease too. We check both, and cleaning can form part of the repair.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

How we price extract fan repair
The price is fixed before any work begins. It takes into account:
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- A single visit or a regular plan
- The size of the system
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.
Asking for a quote
There’s no need for technical detail. Just send:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Problems your staff have spotted
To get a fixed quote, phone us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Keeping the system healthy
To keep the system working properly between visits:
- Don’t turn the fan down to hide a noise
- Make sure the fan is cleaned with the rest of the system
- Report new noises from the fan early
- Keep all filters fitted while cooking
Your kitchen can get back to normal as soon as the fan is running. We leave the area tidy and explain anything you need to know.
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.
Extract fans in South Harrow
Food Standards Agency data counts about 270 cafés, restaurants and staff canteens and about 115 takeaways within 1.5 miles or so of the middle of South Harrow. Those that cook under a canopy rely on a fan that runs every hour they’re open. London extract fans are often at the end of long duct runs, on roofs or in basements. It’s Harrow council that sends environmental health officers to food businesses in South Harrow. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan.
Occasional-use kitchens, such as a hall kitchen near Parish Church of St Paul or elsewhere in South Harrow, are where a stiff or seized fan can turn up. Holidays are the time to replace a tired kitchen fan at schools such as The Welldon Park Academy, rather than mid-term.

When to call us in South Harrow
Kitchen extract fans in South Harrow face the same conditions as anywhere else: hot, greasy, damp air for hours on end. Moisture can rust housings and fixings, and age catches up with every fan in the end.
If you notice any of these, it’s worth a diagnosis:
- A fan that keeps cutting out
- A fan that won’t start at all
- A fan worn beyond sensible repair
- A humming noise from the fan motor
For a takeaway near Northolt Park station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
