How we handle extract fan repair in Mayfair
Everything a kitchen extract does depends on the fan. Once it turns noisy, sluggish or stops altogether, the cooking area soon fills with heat and fumes. We find out why and put it right with a repair or a replacement. Common call-outs are for an extract fan that rattles or knocks and a belt-driven fan that squeals, across bearings, fan motors and belts and pulleys.
In London, getting a new fan to the roof or plant room can take planning, and in Mayfair, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
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. Leave those to us.
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.
When to call us in Mayfair
Blocked filters and greasy ducts make the fan work harder. An overworked motor overheats, trips out or eventually burns out.
These are the problems we see most often:
- A fan running too slowly to clear the kitchen
- A knocking noise from the extract fan
- An extract that vibrates through the ductwork
- A fan that keeps cutting out
If you manage a school such as LITE Regal International School and the kitchen fan is getting louder, the next break is the time to deal with it.
Questions to ask before booking
- Whether the quote is based on a survey or pictures
- When they can work, and whether that is outside your opening hours
- What insurance they carry
- What’s included in the scope, part by part
What the work involves, part by part
Fan controls
Controls are checked as well as the fan itself, because a fan that won’t start is not always a failed motor.
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. The cause might be grease restricting the airflow, or the motor itself may be failing.
Extract fan repair in Mayfair: local notes
Look up Mayfair on the FSA’s food hygiene register and you will find about 3,882 cafés, restaurants and staff canteens and about 380 sandwich bars and takeaways within about 1.5 miles of central Mayfair. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Environmental health officers from Westminster council inspect food businesses in Mayfair. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That’s one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen typically means a closed kitchen, so access details help us plan the repair.
If you cook near Bond Street station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. A fan that rarely runs, like one in a hall kitchen near Grosvenor Chapel or elsewhere in Mayfair, can seize between uses.
Mayfair is about 1 mile south-east of City of Westminster, in Greater London. Mayfair gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. Mayfair is one of 764 towns, villages and districts in Greater London where we work for extract fan repair.
Here we cover the W1K, W1F and W1U postcode area for extract fan repair. Local streets include Park Lane, Bruton Lane and Market Mews, all of which we cover for extract fan repair.

Also close by are Green Park (0.5 miles south) and The St Marylebone CofE School (0.8 miles north). There’s a railway station in Mayfair itself: Bond Street station.

The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Most London sites can’t stop for the day, so work in Mayfair is usually done overnight, early in the morning or at weekends.
- We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
- With the fan safely isolated, we open it up for a proper look.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- We explain the fault and give you a fixed price for the fix.
- Once the work is done, we run the fan and check it’s steady and quiet.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Name a contact who can let us in at the agreed time
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.
Advice
What extract fan repair cannot fix
It’s worth knowing the limits before booking:
- Wiring and supply faults beyond the fan itself
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- An extract system that was undersized from the start
If you are not sure, just call us on 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Why it’s worth doing now in Mayfair
Some kitchens run a noisy fan on a lower speed to cut the noise. That reduces extraction without fixing anything, and the fault carries on developing. Diagnosing the fault properly is the lasting answer. It’s better booked as a planned job in Mayfair than handled as an emergency.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

Your questions about extract fan repair in Mayfair
Can parking be tricky for a job in Mayfair?
A loading bay, a visitor permit or off-street space near the site in Mayfair makes the visit easier to plan. Working overnight, as we often do in London, typically makes it simpler.
Do you cover Mayfair for emergency fan repairs?
We run a 24/7 emergency line for failed extract fans, and Mayfair is part of our area. Use 0345 646 2711, our emergency number, at any time. Let us know whether the fan is silent, noisy or tripping the power.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you replace extract fans as well as repair them?
We can. We fit replacement fans as well as repairing old ones, and we’ll explain the options.
What will a fan repair or replacement cost?
We can’t price it without knowing the fault. After we have checked the fan, we give you a fixed price for whichever option you choose.
What do you do with what you remove?
We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Is it worth cleaning the extract while you’re fixing the fan?
A fan repair on its own doesn’t include the ductwork. We will tell you what we see, so you can decide whether to book a TR19 clean.
Between visits
Here’s the after-treatment advice, in brief:
- Keep the grease filters clean and fitted
- Note when the fan trips or cuts out
- Get a noisy fan checked rather than slowed down
- Save our number for the 24/7 emergency line
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. We then come back and fit them outside your busiest hours.
When filters block, the fan works harder. Changing or cleaning them on time takes load off the motor and protects the motor.
