How we handle extract fan repair in Hampstead
Across Hampstead, we deal with fan faults of every kind, from rattling and humming to a fan that has stopped dead. The fault is diagnosed, quoted at a fixed price and put right or fit a replacement when it’s beyond repair. If you’re dealing with a humming noise from the fan motor and a knocking noise from the extract fan, we can help.
In London, a kitchen without working extraction cannot keep cooking safely, and a closed kitchen loses a night’s trade. In Hampstead, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes anything from an hour or two to a full visit, depending on the fault. For a job in Hampstead, tell us about loading bays, permits, lifts and roof access when you book.

Common questions in Hampstead
Which environmental health team covers Hampstead?
Kitchens in Hampstead are inspected by Camden council’s environmental health officers. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
How do you handle parking and loading in Hampstead?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Will I get paperwork for my records?
Yes. It’s your proof that the work was done: a dated report with pictures, listing the work and any areas we couldn’t reach.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Does a faulty extract fan always need replacing?
That depends on what we find. We diagnose first and tell you whether a repair is realistic and quote a fixed price for the option you choose.
What paperwork should we keep on file?
Everything that shows the system is looked after: our reports and pictures, any certificates and your in-house logs. A single log for each site works best.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Does the report say when we need you again?
Yes. How often depends on use and condition and the report sets out why.
Fixed quotes for extract fan repair in Hampstead
A fixed price needs a few facts first. We look at:
- The times the site is available
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
To get a fixed quote, give us a ring on 0345 646 2711 or email us 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 normally have a quote within one working day.
Looking after it afterwards
Once we have finished, these simple steps help:
- Keep the fan on a planned cleaning cycle
- Report new noises from the fan early
- Write down when the fan misbehaves
- Keep all filters fitted while cooking
Keep an ear on the fan after the repair. A new noise or vibration is worth reporting early, so it can be looked at before it grows.
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 wear is caught earlier.
Different parts, different methods
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Corrosion of housings and fixings is common.
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. It may be straining against blocked filters or ducts or the motor may be near the end of its life.
When a fan fails in Hampstead
Look up Hampstead on the FSA’s food hygiene register and you’ll find about 478 restaurants, cafés and canteens and about 150 sandwich bars and takeaways in Hampstead and the streets around it, up to about 1.5 miles out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. In Hampstead, food businesses are inspected by environmental health officers from Camden council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.
If you run a café or takeaway near Finchley Road & Frognal station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for. A fan that rarely runs, like one in a hall kitchen near St John-at-Hampstead church or elsewhere in Hampstead, can seize between uses.

For landlords and multi-site operators

Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Do you need extract fan repair in Hampstead?
Fixings and anti-vibration mounts work loose or perish over time. Then every vibration is passed into the duct and the building, which is where knocking and rattling often come from.
If you notice any of these, it’s worth a diagnosis:
- Vibration spreading from the fan into the ducts
- Weak extraction and a smoky kitchen
- A motor that trips out or overheats
- A whining or grinding extract motor
If you manage a school such as Fitzjohn's Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.
