When a fan fails in Sunbury-on-Thames
The FSA’s food hygiene register shows about 41 restaurants, cafés and works canteens and about 13 takeaways within roughly a mile and a half of the centre of Sunbury-on-Thames. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Spelthorne council inspect food businesses in Sunbury-on-Thames. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That makes a fan repair urgent rather than something to put off. Sunbury-on-Thames is about 15 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.
Occasional-use kitchens, such as a hall kitchen near St Saviour or elsewhere in Sunbury-on-Thames, are where a stiff or seized fan can turn up. Holidays are the time to replace a tired kitchen fan at schools such as St Ignatius RC Primary School, rather than mid-term.

Leave it or put it right?
In Sunbury-on-Thames, as elsewhere, an extract fan may well sit outside on a wall or roof, where a rattle or a whine can be heard beyond the kitchen. Fixing the cause quietens it down before neighbours notice. An inspector or insurer will want to see recent records, so it makes sense to have them ready.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

Questions from Sunbury-on-Thames
Which council inspects kitchens in Sunbury-on-Thames?
The local authority for Sunbury-on-Thames is Spelthorne council, 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.
Can the work in Sunbury-on-Thames be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Sunbury-on-Thames doesn’t have to lose a day’s trading. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What makes a kitchen extract fan rattle or whine?
There are several possible causes, from a worn bearing to a loose fixing. The safest step is a proper diagnosis before the fault gets worse.
Can you tell me the price of a fan repair?
The cost depends on what’s wrong and how easy the fan is to reach. After diagnosing, you get a fixed quote before any work starts.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Will we have to shut during the visit?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Do you provide a certificate or report?
Yes, on every job. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.

What else we do in Sunbury-on-Thames
What extract fan repair can’t fix
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- A greasy canopy and duct that a fan repair won’t touch
- Faults in the building’s electrical supply, which need an electrician
If you are not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
What the work covers
- Belts and pulleys
- Fan motors
- Roof and wall fans
- Kitchen extract fans
- Fan housings
- Bearings
Different parts, different methods
Impellers and housings
Grease settles inside the fan housing as well as on the blades. Both are inspected and cleaning may be part of the fix.
Direct-drive fans
An impeller coated in grease vibrates straight into the motor bearings. Sometimes a clean is all it needs as long as the bearings are still sound.
In-house cleaning or 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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Signs you need extract fan repair in Sunbury-on-Thames
Over the years, mountings loosen and rubber mounts break down. The fan’s movement then travels into the ductwork and structure, which is where knocking and rattling often come from.
Common reasons sites call us include:
- An old fan that needs replacing
- Poor airflow at the canopy
- A whining or grinding extract motor
- A squealing belt on start-up
If you run a café or takeaway near Sunbury station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Make sure the fan is cleaned with the rest of the system
- Do not turn the fan down to hide a noise
- Do not cook with gaps in the filter bank
- Keep the grease filters clean and fitted
Before we leave, the fan is run and checked. We explain the fault and the fix, and anything else we noticed is pointed out.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and problems are spotted sooner.
