In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
About our TR19 inspection in Fern
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Grease testing shows which side of those lines you’re on. The work covers pre-clean surveys, insurer audits and access surveys, and people most often call us about sites with gaps in their extract records and confirming a clean reached the whole system.
In a village or hamlet like Fern, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Buckinghamshire. Work can be phased by floor, building or site around the people who use them.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- File every inspection report with your certificates
- Clean or swap grease filters as often as the kitchen needs
- Diary the next grease test and clean
- Send TR19 audit reports to your insurer on request
After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
What a clean won’t put right
A few issues sit outside what this work can do:
- Parts of the duct nobody can reach yet
- Design faults in the extract system
- The grease itself, which needs a full or spot clean
If you are not sure, just phone us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes an hour or two for a single kitchen, longer for a large or complex system. If the van will struggle with a lane or gateway near Fern, let us know and we’ll plan around it.
- First we book a time that won’t disrupt cooking.
- Every part of the system is examined, end to end.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, pictures and next steps.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time

When to call us in Fern
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.
These are the problems we see most often:
- Pre-clean surveys before a first TR19 clean
- Cleaning intervals that may not suit the kitchen
- Missing TR19 certificates or history
- Missing access panels found on survey
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Marlow Community Hospital is the nearest hospital to Fern, about 2 miles south-west.
Questions to ask before you book

Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call 0345 646 2711 or email us.
What is a WFTT or DTT grease test?
We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.
Do you check other contractors’ cleans?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It can follow our own cleans or another contractor’s.
TR19 inspection in Fern: the local picture
Look up Fern on the FSA’s food hygiene register and you will find about 16 restaurants, cafés and canteens and about 5 takeaways and sandwich shops in and around Fern, up to about a mile and a half out. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. It’s Buckinghamshire council that sends environmental health officers to food businesses in Fern. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Fern 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.
Volunteers running a hall kitchen near Church of St John the Baptist, or anywhere in Fern, may not know when the extract was last cleaned, and a grease test settles it. Historic houses near Fern, such as Cliveden about 2.7 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
