Kitchen extract cleaning in Chesham Bois
The canopy over the range is only the start of a kitchen extract system. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, and each part collects grease. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. If you’re dealing with stale cooking odours from the system and missing paperwork after a change of operator, we can put it right. Searching for commercial kitchen extraction cleaning in Chesham Bois? We’ve been cleaning kitchen extracts across the South East since 2009, with a certificate and photo report after every clean.
What can be cleaned depends on what can be reached. Sections without access panels are recorded on the report, and new panels can be fitted so they’re cleaned next time.
Size does not change the work: a kitchen in a place like Chesham Bois gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Good records are part of the job. Each visit is written up with photos, 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 to hand when an insurer or inspector asks.

Grease, kitchens and Chesham Bois
The FSA’s food hygiene register shows about 46 restaurants, cafés and canteens and about 14 takeaways across Chesham Bois and its immediate surroundings (about a mile and a half). Any of them cooking under a canopy is sending grease into its ductwork every service. In Chesham Bois, food businesses are inspected by environmental health officers from Buckinghamshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand. Chesham Bois sits within the area of 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.
Volunteers running a hall kitchen near Church of St Leonard, or anywhere in Chesham Bois, may not know when the extract was last cleaned, and a grease test settles it. If you run a café or takeaway near Amersham station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Chesham Bois is about 1 mile north of Amersham, in Buckinghamshire. Chesham Bois gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. We cover 263 places across Buckinghamshire, large and small. Our Reading page covers sites nearby, about 23 miles away.

Part by part
Extract fan and discharge
Grease that reaches the fan coats the blades and the housing. We isolate it, open it up and degrease it.
Canopy and plenum
The canopy catches the vapour, and the plenum behind the filters is where it first condenses. Both are scraped and degreased inside and out, with the filter housing cleaned too.
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Refit filters properly after cleaning
- Do not let the canopy gutters overflow
- Diarise the next clean as soon as you get the certificate
- Report grease drips, smells or fan noise right away
You get a photo report after every clean. Before and after pictures show each part of the system, and lists what was cleaned, any areas we couldn’t reach and the date the next clean is due.
Keep the outside of the canopy wiped and any grease cups emptied. It will not replace a TR19 clean, but it slows what reaches the duct.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Questions from Chesham Bois
Who is the fire and rescue service for Chesham Bois?
Buckinghamshire Fire and Rescue Service is the fire and rescue service for Chesham Bois. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you work in Chesham Bois outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Chesham Bois needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what kitchen extract cleaning will not do:
- Faulty fire dampers in the duct
- Blocked drains from a neglected grease trap (a separate service)
- Damaged duct sections that need replacing
If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think.
What we work on in Chesham Bois
- Plenums and filters
- Vertical risers
- Horizontal duct runs
- Discharge points
- Canopies and hoods
- Extract fans
How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. On site, it takes anything from a few hours to a full night, depending on the size of the system. Around Chesham Bois, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- First the diagnosis: a survey of the whole system and its access points.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
How to get a quote
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.

When to call us in Chesham Bois
A kitchen in Chesham Bois builds up grease in the same places as any other: long horizontal runs, bends, the base of risers and around the fan. The cooler the duct, the more grease drops out of the air.
Look out for these warning signs:
- Proof of cleaning requested by an insurer
- An extract that has never been cleaned to TR19
- Grease dripping from the canopy or filters
- An extract that no longer clears the smoke
If you look after a school kitchen, at a school such as Elangeni School or anywhere near Chesham Bois, the holidays are the usual time for a TR19® clean.
