Part by part
Impellers and housings
Grease settles inside the fan housing as well as on the blades. Both are inspected, and cleaning can form part of the repair.
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Corrosion of housings and fixings is common.
Extract fan repair for kitchens and businesses in South Wimbledon
Across South Wimbledon, we deal with fan faults of every kind, from a squeal at start-up to a fan that will not run at all. We find the cause, give you a fixed price and fix it or fit a replacement when it’s beyond repair. The work covers roof and wall fans, kitchen extract fans and belts and pulleys, and people most often call us about a fan that whines, hums or grinds and a fan that won’t start at all.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. A fan that’s noisy or vibrating is giving a warning.

Managing agents and facilities teams in South Wimbledon
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
What extract fan repair looks like in South Wimbledon
The FSA’s food hygiene register shows about 370 cafés, restaurants and staff canteens and about 68 sandwich bars and takeaways within roughly a mile and a half of the centre of South Wimbledon. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. It’s Merton council that sends environmental health officers to food businesses in South Wimbledon. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That makes a fan repair urgent rather than something to put off. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.
For school kitchens, at schools like Holy Trinity CofE Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time. Occasional-use kitchens, such as a hall kitchen near Holy Trinity or elsewhere in South Wimbledon, are where a stiff or seized fan can turn up. For kitchens close to Wimbledon station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

Why act early in South Wimbledon
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Even without an interlock, cooking without extraction is not sensible, so a failing fan is worth dealing with early. A building in South Wimbledon may have flats or offices above and alongside, and a fault in the system can affect them too.
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.

The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a few hours on site, depending on the fault and the access to the fan. In a London area like South Wimbledon, parking, loading and building access are planned before the day of the work.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Before we arrive
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or send us an email.
Advice
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Never run the extract with filters missing
- Make sure the fan is cleaned with the rest of the system
- Keep access to the fan controls unobstructed
- Make sure every filter is in place and clean
Where parts need ordering, we explain what that means for the kitchen until we return. The fan is completed on a return visit outside your busiest hours.
The fan is part of every full TR19 clean. A clean impeller stays in balance, so planned cleaning helps the fan last.

Honest limits
Extract fan repair cannot fix everything, and we’ll tell you before we start. It will not put right:
- Problems with the gas supply or its interlock valve
- Grease build-up in the rest of the extract system
- Odour complaints that need filtration rather than a fan repair
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
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.
Questions from South Wimbledon
What if my kitchen extract fan stops in South Wimbledon at night?
We run a 24/7 emergency line for failed extract fans, and South Wimbledon is part of our area. Use 0345 646 2711, our emergency number, at any time. A photo of the fan’s rating plate helps.
Who would carry out a food hygiene inspection at a kitchen in South Wimbledon?
Kitchens in South Wimbledon are inspected by Merton council’s environmental health officers. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
Who has the legal duty for fire safety?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Does the law say we must follow TR19?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
Do we need to close while you work?
Usually not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
