Extract fan repair for kitchens and businesses in City of London
If an extract fan in City of London is struggling or has stopped, we diagnose the fault and send you a fixed quote for the repair or the replacement. For a fan that fails during service, there’s a 24/7 emergency callout. We are often asked to deal with a fan that whines, hums or grinds and a fan shaking on its mountings, on bearings, fan motors and fan housings.
For a London kitchen, a failed extract fan normally means the cooking stops, and a closed kitchen loses a night’s trade. In City of London, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.
The sign-off is always in writing: a dated report with photos of the work, 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.

What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
City of London: your questions answered
Does London parking affect a job in City of London?
Tell us where a van can stop near your site in City of London, and about any building rules on loading. Much of our London work is done overnight, which helps.
Who inspects food businesses in City of London?
The local authority for City of London is the City of London Corporation, and its environmental health team does the inspecting. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Is there help out of hours when the extract fails?
We run a 24/7 emergency callout for exactly this. We’ll talk it through with you and arrange to attend as quickly as possible.
Is repair an option before replacing the whole fan?
We look at repairing it first. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we will explain why.
What causes a noisy extract fan?
There are several possible causes, including bearings, belts, grease and mounts. It’s worth having it diagnosed before it leads to a breakdown.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Do you recommend a next date?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.

What affects the cost of extract fan repair
You’ll get a fixed price before we start. It’s based on:
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Helping us quote
We can often survey from pictures. Try to include:
- Any previous report or certificate
- When the site is open and when it’s quiet
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
What extract fan repair looks like in City of London
Look up City of London on the FSA’s food hygiene register and you’ll find about 3,230 restaurants, cafés and canteens and about 953 takeaways and sandwich shops within roughly a mile and a half of the centre of City of London. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange. Environmental health officers from the City of London Corporation inspect food businesses in City of London. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off.
For a takeaway near London Cannon Street station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7. Holidays are the time to replace a tired kitchen fan at schools such as Fashion Retail Academy, rather than mid-term.

What we’re called out for in City of London
Not every problem is mechanical. A failed speed controller or a wiring fault can stop a fan so we check the controls before blaming the motor.
Keep an eye out for any of the following:
- A fan rattling in its housing
- A humming noise from the fan motor
- An old fan that needs replacing
- A motor that trips out or overheats
A fan that rarely runs, like one in a hall kitchen near St Olave Old Jewry or elsewhere in City of London, can seize between uses.
Questions to ask before you book
- What happens if part of the system cannot be accessed
- Which accreditations they hold, and whether you can check them
- Whether a survey comes first
- What hours they’ll be on site
Why it’s worth doing now in City of London
A struggling motor runs hotter and works harder. Every hour of strain takes its toll, and when it finally fails, it may take other parts with it. Catching it early keeps the repair small. A booked night’s work in City of London costs you no trading time; an unplanned closure does.
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

Honest limits
We will not sell you work that doesn’t address the problem, so here are the limits:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Smells from the discharge that need odour control equipment
- Ductwork designed too small for the kitchen’s cooking
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.
What the work covers
- Bearings
- Fan housings
- Roof and wall fans
- Kitchen extract fans
- Fan motors
- Belts and pulleys
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Make sure the isolator and controls are easy to reach
- Never run the extract with filters missing
- Get a noisy fan checked rather than slowed down
- Clean or change filters on schedule
Once we’re done, the extract is back in service. We clear up after ourselves and talk you through what we found.
Small faults, like a worn belt, are quick to fix. Ignored, they can lead to bigger failures, so it’s worth acting early.
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a few hours for most repairs, longer for a full fan replacement. If your building in City of London has sign-in rules, permits or key holders, mention them when you book.
- 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.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
How to prepare
