How we handle extract fan cleaning in Chalfont St Peter
The fan is cleaned as part of every full TR19® Grease clean, but some fans need cleaning between full cleans, especially when it has started to vibrate or sound rough. Where only the fan is cleaned, the report says so. The work covers axial fans, centrifugal fans and roof-mounted fans, and people most often call us about a fan that no longer moves enough air and vibration from an unbalanced impeller.
Around a smaller place like Chalfont St Peter, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Part by part
Impellers and blades
The impeller is the spinning part that moves the air, and it collects grease unevenly. That is what unbalances the fan, so it’s cleaned carefully blade by blade.
Fan housings and motors
The housing around the impeller catches grease flung off the blades. It’s scraped and degreased with the impeller.
Keeping the system healthy
So the system stays in good health:
- Keep access to the fan clear
- Keep each photo report with the maintenance log
- Look for grease stains near the discharge
- Tell us if the extract feels weaker
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Do not run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Leave it or put it right?
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. It’s better to plan the work at a site near Chalfont St Peter than wait for a failure.
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 we start.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: 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.
What extract fan cleaning looks like in Chalfont St Peter
The FSA’s food hygiene register shows about 41 restaurants, cafés and canteens and about 13 sandwich bars and takeaways within about 1.5 miles of central Chalfont St Peter. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. In Chalfont St Peter, food businesses are inspected by environmental health officers from Buckinghamshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Chalfont St Peter is covered by Buckinghamshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chalfont St Peter is Chalfonts and Gerrards Cross Hospital, about less than half a mile west.

How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes an hour or two for most single fans. Tell us about any gates, ladders or locked plant areas at your site near Chalfont St Peter when you book.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- We remove the grease from the blades, impeller and casing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
What a clean will not put right
To be straight with you, some problems need a different fix:
- A fan that was never right for the kitchen
- Wiring faults to the fan
- A failed motor or worn bearings (that needs a fan repair or replacement)
If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think.
What the work covers
- Roof-mounted fans
- Axial fans
- In-line fans
- Centrifugal fans
- Fan housings
- Discharge points
