Extract fan repair for kitchens and businesses in Hook
Working on a fan in Hook means switching the extract off first, so we plan it around your service. We can work in the evening, overnight or at the weekend and there’s a 24/7 emergency line if the fan fails while you are cooking. The work covers belts and pulleys, fan motors and kitchen extract fans, and common reasons people get in touch are an extract that vibrates through the ductwork and a fan that keeps cutting out.
Replacing a fan in a London building often means working at height or in a tight plant space, with parking and lifting to arrange in Hook. Work can be done after service, so the kitchen loses as little time as possible.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes an hour or two to diagnose, then longer if parts or a new fan are needed. In a London area like Hook, parking, loading and building access are planned before the day of the work.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t 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.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Why deal with it now?
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Even without an interlock, cooking without extraction isn’t sensible, so a failing fan is worth dealing with early. A booked night’s work in Hook costs you no trading time; an unplanned closure does.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

When it’s something else
In fairness, some problems need a different fix:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Odour complaints that need filtration rather than a fan repair
- A system that needs redesigning rather than repairing
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 before booking.
Parts of the system we cover

How we price extract fan repair
The diagnosis comes before the price. The main factors are:
- Where the site is and how we reach it
- How big the system is
- The times the site is available
- Site requirements such as sign-in and permits
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or email us, and we’ll explain what it covers.
Helping us quote
You do not need the technical terms. Just send:
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711, or send details by email.
Extract fan repair around Hook
Food Standards Agency data counts about 83 cafés, restaurants and staff canteens and about 36 takeaways within about 1.5 miles of central Hook. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Kitchens in Hook get their food hygiene inspections from Kingston-Upon-Thames council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That makes a fan repair urgent rather than something to put off. London extract fans are often at the end of long duct runs, on roofs or in basements.
Holidays are the time to replace a tired kitchen fan at schools such as St Paul's CofE Primary School, rather than mid-term. Occasional-use kitchens, such as a hall kitchen near St Paul's or elsewhere in Hook, are where a stiff or seized fan can turn up.

Signs you need extract fan repair in Hook
Over the years, mountings loosen and rubber mounts break down. Then every vibration is passed into the duct and the building and that is a common source of rattles.
Signs it’s time to call us include:
- A belt-driven fan that squeals
- A fan that keeps cutting out
- A knocking noise from the extract fan
- An extract fan that has stopped working
If you run a kitchen close to Chessington North station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

Questions from Hook
Do you work overnight in Hook?
Yes, nights and weekends are routine for us. It means the site in Hook keeps running as normal. Let us know the hours you are closed and we will book within them.
Which environmental health team covers Hook?
Food hygiene inspections in Hook are carried out by Kingston-Upon-Thames council. Keeping the fan serviced is easier than explaining a broken one on inspection day.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
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.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
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.
How long does an extract fan repair take?
It depends on the fault, but most jobs take a few hours on site, depending on the fault and the access to the fan. You’ll know more once we have found the fault.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Write down when the fan misbehaves
- Book regular TR19 cleaning, which includes the fan
- Report new noises from the fan early
- Make sure every filter is in place and clean
Your kitchen can get back to normal as soon as the fan is running. We clear up after ourselves and talk you through what we found.
Clogged filters make the fan strain. Changing or cleaning them on time takes load off the motor and protects the motor.
