Extract fan cleaning in Cannon Hill, done properly
A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Common call-outs are for a smell of hot grease from the extract and a heavily greased fan housing, on discharge points, axial fans and centrifugal fans.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Cannon Hill, that typically means a longer system to clean and more access panels to plan around.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Common problems we fix in Cannon Hill
A greasy fan in Cannon Hill is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
Any of these means the system needs a check-up:
- A fan shaking on its mounts
- A fan that has never been cleaned
- Rough running from the extract fan
- Less air being pulled from the kitchen
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St. Anthony's Hospital is the nearest hospital to Cannon Hill, about 1.5 miles south.
What to look for in a quote
- Whether the quote is based on a survey or photos
- Whether the quote shows VAT
- When they can work, and whether that is outside your opening hours
- Whether the figure could change on the day
What happens on the day
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the extract fan cleaning, clear away and hand over the paperwork. The visit itself takes a few hours where there are several fans or heavy deposits. Security desks and permits-to-work are routine in London, so let us know what your building in Cannon Hill needs from us.
- We start by checking where the fan sits and how to isolate it.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
Getting ready for the visit
- Clear loose items from the work area
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need

FAQs for Cannon Hill
Who inspects food businesses in Cannon Hill?
In Cannon Hill, it’s Merton council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can a school canteen extract in Cannon Hill be done out of term time?
Yes. The holidays are the usual time for school work. There are about 34 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Cannon Hill. Booking early in the term gives the best choice of holiday dates.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
What if the fan needs more than a clean?
Fan repair and replacement is part of what we do. If cleaning shows a worn motor, bearings or impeller, we will tell you and quote for the repair.
Is there a survey before the work?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Why act early in Cannon Hill
A greasy fan has to work harder to move the same air. Airflow at the canopy drops and the kitchen gets hotter and smokier, while the motor runs under more strain. In Cannon Hill, a planned overnight visit is much easier than closing unexpectedly.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.

- One number for every site across the South East and London

Part by part
Roof-mounted fans
Roof fans sit at the top of the riser. We clean them where they can be safely reached, and anything we can’t reach is recorded.
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Leave a clear route to the fan
- Keep records of every fan clean
- Flag smoke lingering at the canopy
- Make sure the fan is included each time
If the fan needs more than a clean, we will say so plainly. We also repair and replace extract fans, so you have one point of contact.
Keep the route to the fan clear. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
Extract fan cleaning in Cannon Hill: the local picture
Food Standards Agency records list about 212 restaurants, cafés and works canteens and about 52 takeaways and sandwich shops across Cannon Hill and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Kitchens in Cannon Hill get their food hygiene inspections from Merton council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Cannon Hill falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
For kitchens close to South Merton station, where the day often starts early and ends late, the extract can be cleaned overnight. Volunteers running a hall kitchen near St James Merton, or anywhere in Cannon Hill, may not know when the extract was last cleaned, and a grease test settles it.
