When a fan fails in South Hampstead
There are about 625 restaurants, cafés and works canteens and about 265 sandwich bars and takeaways in and around South Hampstead, up to about a mile and a half out, according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. In South Hampstead, food businesses are inspected by environmental health officers from Camden 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.
For school kitchens, at schools like The UCL Academy for example, a planned fan repair in the holidays avoids losing lunches in term time. Occasional-use kitchens, such as a hall kitchen near Church of All Souls or elsewhere in South Hampstead, are where a stiff or seized fan can turn up. For a takeaway near South Hampstead station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.

How we handle extract fan repair in South Hampstead
Across South Hampstead, we deal with fan faults of every kind, 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 fit a replacement when it’s beyond repair. Typical jobs include an extract that vibrates through the ductwork and a worn or slipping fan belt, on bearings, roof and wall fans and fan motors.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. Noise and vibration are worth reporting before the fan stops.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What affects the cost of extract fan repair
You will get a fixed price before any work starts. It’s based on:
- Parking and loading at the site
- How many systems or sites are involved
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
Asking for a quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- A few general shots of the system
- Your last certificate, test record or report

What else we do in South Hampstead
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from an hour or two to a full visit, depending on the fault. In South Hampstead, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We ask what the fan is doing, from noise and vibration to a full stop.
- The fan is isolated and opened up so we can see inside.
- We check the motor, bearings, drive, impeller and mountings.
- We explain the fault and give you a fixed price for the fix.
- Once the work is done, we run the fan and check it’s steady and quiet.
How to prepare
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system
- Let us know about parking and loading

Honest limits
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Ductwork designed too small for the kitchen’s cooking
- Odour complaints that need filtration rather than a fan repair
- Grease build-up in the rest of the extract system
If you are not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer before you book.
Parts of the system we cover
- Fan housings
- Bearings
- Belts and pulleys
- Fan motors
- Roof and wall fans
- Kitchen extract fans
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Book regular TR19 cleaning, which includes the fan
- Do not turn the fan down to hide a noise
- Note when the fan trips or cuts out
- Make sure every filter is in place and clean
Clean filters help a repaired fan stay that way. The less grease that reaches the fan, the longer its parts last and fewer faults.
A fan that’s starting to make noise is giving you a warning. Getting it checked now means a planned repair instead of a breakdown at the worst moment.
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Different parts, different methods
Fan controls
Speed controllers and isolators sit between the supply and the fan. A control fault can leave the fan dead or stuck at one speed.
Belt-driven fans
Belt-driven fans have a motor that turns the impeller through belts and pulleys. Worn belts squeal and slow the fan down, and pulleys and bearings need checking too.
Why it’s worth doing now in South Hampstead
Left alone, vibration spreads its damage. Fixings work loose and joints in the ductwork can be strained, so a small repair can grow into a bigger one. It’s better booked as a planned job in South Hampstead than handled as an emergency.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

FAQs for South Hampstead
Can parking be tricky for a job in South Hampstead?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Do you work overnight in South Hampstead?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you ring 0345 646 2711 or use the quote form, mention when the site is quiet.
Does a fan repair include cleaning the ductwork?
Doing both together is often sensible. A full clean takes in the whole extract, including the fan, with a certificate and photo report.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Will we have to shut during the visit?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Is South Hampstead in your area?
Yes. Our technicians work in South Hampstead, as part of our area across London and the South East.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.
