Extract fan repair in Hounslow, done properly
Kitchens in Hounslow call us about extract fans and motors that are noisy, slow or dead, we find the cause and quote a fixed price to repair or replace it. For a fan that fails during service, there’s a 24/7 emergency callout. If you’re dealing with an old fan that needs replacing and a belt-driven fan that squeals, we can help.
In London, a kitchen without working extraction cannot keep cooking safely, and a closed kitchen loses a night’s trade. In Hounslow, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes anything from an hour or two to a full visit, depending on the fault. For a job in Hounslow, tell us about loading bays, permits, lifts and roof access when you book.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- Power to the fan is isolated before we open the housing.
- We check the motor, bearings, drive, impeller and mountings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- Once the work is done, we run the fan and check it’s steady and quiet.
Preparing for the visit
- Let us know about parking and loading
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
Ask for a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.

Questions from Hounslow
Do you cover Hounslow for emergency fan repairs?
We run a 24/7 emergency line for failed extract fans, and Hounslow is part of our area. The number to ring is 0345 646 2711. Tell us where the fan is and how to reach it.
Which council inspects kitchens in Hounslow?
The local authority for Hounslow is Hounslow council, and its environmental health team does the inspecting. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you replace extract fans as well as repair them?
We can. We fit replacement fans as well as repairing old ones and we will talk you through what’s involved.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Will we have to shut during the visit?
Usually not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Is it worth cleaning the extract while you’re fixing the fan?
A repair deals with the fan, not the grease in the rest of the system. If there’s grease on the fan, a full TR19® clean is worth booking, and we can arrange both.
What affects the cost of extract fan repair
We do not publish a price list, because no two systems are the same. The quote depends on:
- How easy every part is to reach
- Where the site is and how we reach it
- The size of the system
- Working hours and out-of-hours timing
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- Your last certificate, test record or report
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, call 0345 646 2711 or send us an email.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Why deal with it now?
A fan that’s running slowly is not clearing the kitchen properly. The kitchen becomes an uncomfortable place to work, and more grease settles where it shouldn’t. A booked night’s work in Hounslow costs you no trading time; an unplanned closure does.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
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.
Extract fan repair around Hounslow
Food Standards Agency records list about 313 restaurants, cafés and works canteens and about 111 sandwich bars and takeaways within 1.5 miles or so of the middle of Hounslow. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. In Hounslow, food businesses are inspected by environmental health officers from Hounslow council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan. London extract fans are often at the end of long duct runs, on roofs or in basements.
If you manage a school such as Chatsworth Primary School and the kitchen fan is getting louder, the next break is the time to deal with it. Occasional-use kitchens, such as a hall kitchen near Church of St Mary the Virgin or elsewhere in Hounslow, are where a stiff or seized fan can turn up.

Signs you need extract fan repair in Hounslow
Some faults are in the controls rather than the fan. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
The symptoms we are asked about most include:
- A fan that whines, hums or grinds
- Weak extraction and a smoky kitchen
- An extract fan that rattles or knocks
- A failed fan that needs a replacement
For a takeaway near Hounslow station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
What to look for in a quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What records you will receive afterwards
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Keep a record of any trips or stoppages
- Do not cook with gaps in the filter bank
- Keep the grease filters clean and fitted
- Do not turn the fan down to hide a noise
Keep an ear on the fan after the repair. A new noise or vibration is worth reporting early rather than waiting for it to fail.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, so the fan is looked at as part of each visit and problems are spotted sooner.
