Grease, kitchens and Chesham Bois
According to Food Standards Agency records, there are about 17 pubs and bars within roughly a mile and a half of the centre of Chesham Bois. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Chesham Bois get their food hygiene inspections from Buckinghamshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Chesham Bois is covered by Buckinghamshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chesham Bois is Amersham Hospital, about 1.7 miles south-west. If you cook for passing trade around Amersham station, the extract can be cleaned between your last and first customer. 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.

For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes an hour or two for one fan, longer when it’s hard to reach. In a smaller place like Chesham Bois, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
How to prepare
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
- Name a contact who can let us in at the agreed time

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Your questions about extract fan cleaning in Chesham Bois
Do you work in villages like Chesham Bois?
Yes, Chesham Bois is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can you come to Chesham Bois after we close?
Yes, we can come after you close and finish before you open. That way a site in Chesham Bois does not have to lose a day’s trading. When you phone us on 0345 646 2711, or send details by email, mention when the site is quiet.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What information do you need?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
What makes a kitchen extract fan vibrate?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

Honest limits
Not every problem is solved by extract fan cleaning, and we’d rather say so up front. It doesn’t solve:
- An impeller that’s bent or split
- An undersized fan that can’t cope
- A dirty duct upstream of the fan
If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.
Parts of the system we cover
- Fan housings
- Centrifugal fans

- Axial fans
- Discharge points
- In-line fans
How the job changes from site to site
Impellers and blades
Coated blades move less air. We clean each blade back to its surface, so the fan can run as intended.
Inline duct fans
Inline fans can be in tight spaces, so we plan how to reach and clean them. Anything out of reach is recorded.
Aftercare tips
After the visit, a few habits help the work last:
- File the fan’s report with your other records
- Do not store items in front of the fan’s access point
- Notice when the fan starts to sound different
- Watch for grease marks around the outlet
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.
Make sure the fan is reachable. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
Why act early in Chesham Bois
A fan that fails mid-service can stop a kitchen cooking. Grease is often where fan trouble begins, so keeping it clean is part of keeping it running. We also offer a 24/7 emergency callout if the worst happens. A site near Chesham Bois that has to close at short notice is hard to cover for.
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 are not sure what’s needed, ring 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
