Which council inspects kitchens in Cannon Hill?
Food hygiene inspections in Cannon Hill are carried out by Merton council. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
What will a fan repair or replacement cost?
The price depends on the diagnosis. Once we’ve looked at it, you get a fixed quote for the repair or the replacement.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
Who is the responsible person?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What paperwork should we keep on file?
Anything that proves the system is maintained: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.
About our extract fan repair in Cannon Hill
Think of it as a check-up for the fan: listen to it, diagnose the fault, then treat it. The aim is steady, quiet extraction and a plain account of what we found. If you’re dealing with an extract fan that has stopped working and poor airflow at the canopy, we can put it right, from fan motors, bearings and belts and pulleys onwards.
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.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Cannon Hill
A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly and the fan may stop when you are busiest. A repair booked now is simpler than an emergency later. In Cannon Hill, as across London, ductwork often passes through shared risers and other people’s space.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Note when the fan trips or cuts out
- Make sure every filter is in place and clean
- Don’t turn the fan down to hide a noise
- Keep the area around the fan controls clear
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 scheduled maintenance plan keeps the whole system on a regular cycle, so the fan is looked at as part of each visit and problems are spotted sooner.
Common problems we fix in Cannon Hill
Bearings wear out with heat and long hours. As they wear, you hear a whine or a rumble and a seized bearing stops the fan.
What we’re most often called out for:
- An overheating extract motor
- A whining or grinding extract motor
- A squealing belt on start-up
- Weak extraction and a smoky kitchen
Holidays are the time to replace a tired kitchen fan at schools such as Hillcross Primary School, rather than mid-term.

What else we do in Cannon Hill
When a fan fails in Cannon Hill
There are about 212 restaurants, cafés and canteens and about 52 sandwich bars and takeaways across Cannon Hill and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. For any of them with a canopy, the extract fan is what keeps the kitchen usable. A failed fan in a London kitchen typically means a closed kitchen, so access details help us plan the repair. Food hygiene inspections in Cannon Hill are the job of Merton council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly.
If you cook near South Merton station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. A fan that rarely runs, like one in a hall kitchen near St James Merton or elsewhere in Cannon Hill, can seize between uses.

What affects the cost of extract fan repair
You’ll get a fixed price before work begins. It’s based on:
- The number of sites or systems
- What state the system is in
- The times the site is available
- How big the system is
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What we need to know
You don’t need the technical terms. It helps if you can send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
How it works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the extract fan repair, tidy up and leave you the report. On site, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Expect the work in Cannon Hill to happen after your last customer leaves, not during trading.
- A visit is booked, in the evening or overnight if that suits.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
