Extract fan repair and replacement in Totteridge, Greater London
Extract fan repair for Totteridge, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- An old fan that needs replacing
- A dead fan motor
- A knocking noise from the extract fan
What your team can do, and what needs us
Some jobs should never be done in-house: 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.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
How we handle extract fan repair in Totteridge
A faulty fan doesn’t always mean a new one. Sometimes cleaning the impeller or renewing worn parts is enough and we will say so. Where the motor has burnt out or the unit is past saving, a replacement suited to the system goes in. We’re often asked to deal with a knocking noise from the extract fan and a fan that whines, hums or grinds, across belts and pulleys, fan housings and roof and wall fans.
For a London kitchen, a failed extract fan typically means the cooking stops. Fans in Totteridge are often on a roof or in a basement at the end of a long duct run, 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 if it’s left?
A struggling motor runs hotter and works harder. Every hour of strain takes its toll and a burnt-out motor is a bigger job than a worn belt. Catching it early keeps the repair small. In Totteridge, as across London, ductwork often passes through shared risers and other people’s space.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Between visits
Good habits slow the build-up between visits. A few tips:
- Make sure every filter is in place and clean
- Get a noisy fan checked rather than slowed down
- Don’t wait for a noisy fan to stop
- Keep the emergency number where staff can see it
Once the fan is running smoothly, keep the filters clean. The less grease that reaches the fan, the longer its parts last and fewer faults.
Clogged filters make the fan strain. Keeping filters clean eases the strain and helps prevent overheating.
Extract fans in Totteridge
The FSA’s food hygiene register shows about 93 cafés, restaurants and staff canteens and about 35 sandwich bars and takeaways across Totteridge and its immediate surroundings (about a mile and a half). A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange. Food hygiene inspections in Totteridge are the job of Barnet council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority.
If you run a church or community hall kitchen, near St Andrew's Church or elsewhere in Totteridge, an extract fan that rarely runs can seize or fail when it’s needed. Holidays are the time to replace a tired kitchen fan at schools such as The Totteridge Academy, rather than mid-term.

What else we do in Totteridge
Different parts, different methods
Fan controls
Every fan has controls, from a speed controller to an isolator. A control fault can leave the fan dead or stuck at one speed.
Roof and wall-mounted fans
Fans are often mounted on roofs or external walls. Access affects how long a repair takes, so we ask about it early.
Totteridge questions
How do you handle parking and loading in Totteridge?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Can you come to Totteridge after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
How long does an extract fan repair take?
As a guide, it takes a few hours for most repairs, longer for a full fan replacement. Where parts need ordering, we’ll explain the timescale.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Do you provide a certificate or report?
Yes. It’s the record insurers and inspectors ask to see: a dated report with pictures, listing the work and any areas we couldn’t reach.
What paperwork should we keep on file?
Each report and certificate we give you, filed in the maintenance log with your in-house cleaning records. BESA advises that certificates record the date, location and technician.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes an hour or two to diagnose, then longer if parts or a new fan are needed. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Totteridge.
- We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
- With the fan safely isolated, we open it up for a proper look.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- We fix or replace the fan, then test it running before we leave.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
Ask for a quote
For a fixed quote, give us a ring on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will typically have a quote within one working day.

- A greasy canopy and duct that a fan repair will not touch

- Ductwork designed too small for the kitchen’s cooking
If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think.
