Extract fan repair around Swiss Cottage
Food Standards Agency records list about 625 restaurants, cafés and works canteens and about 265 takeaways within about 1.5 miles of central Swiss Cottage. Wherever they cook under a canopy, a failed extract fan stops the kitchen. London extract fans are often at the end of long duct runs, on roofs or in basements. Environmental health officers from Camden council inspect food businesses in Swiss Cottage. 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.
Hall kitchens near Church of All Souls, or anywhere around Swiss Cottage, often use their fans only now and then, and an idle fan can stick. If you run a school kitchen, at a school such as The UCL Academy or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term.

Extract fan repair in Swiss Cottage
Before anything is ordered, we diagnose. The motor, drive, impeller, bearings and mounts are all checked, along with the fan’s controls. Then you’re given a fixed quote for the repair or the replacement. The work covers roof and wall fans, kitchen extract fans and bearings, and the jobs we see most are weak extraction and a smoky kitchen and an extract that vibrates through the ductwork.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. Noise and vibration are worth reporting before the fan stops.
Nothing is signed off by word of mouth: 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.

Why act early in Swiss Cottage
An overloaded motor is under constant strain. That shortens its life, and when it finally fails, it may take other parts with it. Catching it early keeps the repair small. Leaving it on a busy London site only adds to the work.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.

Do you need extract fan repair in Swiss Cottage?
Blocked filters and greasy ducts make the fan work harder. An overworked motor overheats, trips out or eventually burns out.

- A motor that trips out or overheats
- A worn or slipping fan belt
- An extract that vibrates through the ductwork
- An extract fan that has stopped working
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.

Questions from Swiss Cottage
What do you need to know about parking in Swiss Cottage?
Tell us where a van can stop near your site in Swiss Cottage, and about any building rules on loading. Much of our London work is done overnight, which helps.
Do you work at weekends in Swiss Cottage?
Yes, evening, overnight and weekend work is normal for us. The work in Swiss Cottage can fit around your hours. Your opening times are the first thing we ask for.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
Do you cover Swiss Cottage?
Yes. We work in Swiss Cottage and across Greater London, as part of our work across South East England and London. To book, call 0345 646 2711, or email photos.
Who is responsible for fire safety on the premises?
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.
Will you tell us when the next visit is due?
Yes. The report recommends when the next visit should be, based on use and what we found.
Does a faulty extract fan always need replacing?
We look at repairing it first. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we’ll explain why.
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 it leads to a breakdown.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a few hours for most repairs, longer for a full fan replacement. Most London sites can’t stop for the day, so work in Swiss Cottage is typically done overnight, early in the morning or at weekends.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Before we arrive
- Name a contact who can let us in at the agreed time
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
For a fixed quote, phone us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.
Related advice
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Different parts, different methods
Impellers and housings
Where an impeller is bent or corroded, cleaning won’t help. It may need replacing, or the fan may need replacing as a whole.
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Corrosion of housings and fixings is common.
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Honest limits
A few issues sit outside what this work can do:
- Cooking smells reaching neighbours, which may need odour control
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- A system that needs redesigning rather than repairing
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before you book.
