How the job changes from site to site
Belt-driven fans
Belt-driven fans have a motor that turns the impeller through belts and pulleys. Belts wear, stretch and slip, so we check the pulleys and bearings as well.
Impellers and housings
A damaged or corroded impeller can’t simply be cleaned. It may be replaced on its own, or with the whole fan.
Extract fan repair in Leamouth
Our engineers handle all sorts of fan faults in Leamouth, from a squeal at start-up to a fan that won’t run at all. The fault is diagnosed, quoted at a fixed price and put right, or the fan is replaced if repair does not make sense. The work covers roof and wall fans, kitchen extract fans and belts and pulleys, and the jobs we see most are a belt-driven fan that squeals and an extract fan that rattles or knocks.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. A fan that’s noisy or vibrating is giving a warning.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Questions from Leamouth
Can you come out to a failed extract fan in Leamouth out of hours?
We run a 24/7 emergency line for failed extract fans, and Leamouth is part of our area. Ring 0345 646 2711 at any hour and describe the fault. If you can, stop cooking until the fan is checked.
Does London parking affect a job in Leamouth?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What if parts of the system can’t be reached?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What will a fan repair or replacement cost?
Every fan job is priced once we know the fault. Repair, parts or a full replacement all cost differently, so call 0345 646 2711, or email photos and we will arrange a diagnosis.
Will you fit a new fan if ours cannot be repaired?
Yes. If repair isn’t sensible, we replace the fan. We check the duct size and the extract the kitchen needs before recommending a unit.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
Common problems we fix in Leamouth
Any kitchen that cooks for long hours works its fan hard, in Leamouth or anywhere else. Belts on a belt-driven fan stretch and wear, so the fan squeals or turns more slowly.
Clients usually contact us when they notice something like this:
- A fan that whines, hums or grinds
- A fan that won’t start at all
- A failed fan that needs a replacement
- Weak extraction and a smoky kitchen
For kitchens close to Custom House station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.
Before booking anyone
- What paperwork you get at the end
- Whether they recommend a next date
- If they look at the system before pricing
- What happens if part of the system cannot be accessed
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Book regular TR19 cleaning, which includes the fan
- Keep all filters fitted while cooking
- Keep access to the fan controls unobstructed
- Write down when the fan misbehaves
We run the fan and check it’s steady before we go. You will hear what we found and what we did, and anything else we noticed is pointed out.
Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes an hour or two to diagnose, then longer if parts or a new fan are needed, and we clear up before we go. Loading bays, visitor permits and roof access are the first things we ask about for a site in Leamouth.
- We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
- The fan is isolated and opened up so we can see inside.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- The repair or replacement is carried out and the fan is run and checked.
How to prepare
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one
Get a fixed quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or email us.
Advice
What extract fan repair can’t fix
It’s worth knowing the limits before booking:
- Odour complaints that need filtration rather than a fan repair
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Grease build-up in the rest of the extract system
If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think before booking.

Extract fan repair around Leamouth
Food Standards Agency records list about 465 restaurants, cafés and canteens and about 172 sandwich bars and takeaways within roughly a mile and a half of the centre of Leamouth. Those that cook under a canopy rely on a fan that runs every hour they’re open. It’s Tower Hamlets council that sends environmental health officers to food businesses in Leamouth. 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. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like St Luke's Primary School, fix a failing fan before term starts. A fan that rarely runs, like one in a hall kitchen near Church of St Luke or elsewhere in Leamouth, can seize between uses.

Why act early in Leamouth
Wherever the kitchen is, Leamouth included, the fan often sits on an outside wall or roof, so its noise does not stay in the kitchen. Dealing with the fault brings the noise back down before it becomes a nuisance. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
