TR19 inspections and grease testing in Stone, Buckinghamshire

How the job changes from site to site
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
About our TR19 inspection in Stone
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. If you are dealing with extracts that may be over the 200 micron mean and systems cleaned on a calendar with no measurements, we can put it right.
Work in a small place like Stone starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What else we do in Stone
Why it’s worth doing now in Stone
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. Systems in rural buildings are often out of sight and out of mind.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why book with us
- Out-of-hours work and a 24/7 emergency line
- One number for every site across the South East and London
- We’re fully insured
- CHAS, SafeContractor and ISO 9001
See our cost guide or our accreditations.
What affects the cost of TR19 inspection
There’s no set price list, because no two systems are the same. The quote depends on:
- Working hours and out-of-hours timing
- Travel, parking and unloading
- The scale of the work
- The condition of the system
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
Helping us quote
To help us quote quickly, send us:
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
TR19 inspection in Stone: the local picture
Food Standards Agency records list about 3 restaurants, cafés and works canteens across Stone and its immediate surroundings (about a mile and a half). Each kitchen extract among them can be measured for grease to set the right cleaning interval. Kitchens in Stone get their food hygiene inspections from Buckinghamshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Stone falls to Buckinghamshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St John's Hospital is the nearest hospital to Stone, about 0.5 miles west. Where a hall near Church of St John the Baptist, or anywhere in Stone, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Stone is about 2 miles south-west of Aylesbury, in Buckinghamshire. Stone 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.

Common questions in Stone
Can you come to Stone after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Stone needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Which environmental health team covers Stone?
Kitchens in Stone are inspected by Buckinghamshire council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Can you quote from photos?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then phone us on 0345 646 2711, or email photos.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.
How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, 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. A few photos of the system help us make the most of a visit to a place like Stone.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Before we arrive
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one

When to call us in Stone
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
These are the problems we see most often:
- Systems cleaned on a calendar with no measurements
- Extracts that may be over the 200 micron mean
- Pre-clean surveys before a first TR19 clean
- Missing access panels found on survey
Term dates shape school work: for a school like Stone Church of England Combined School, an extract clean fits neatly into a half-term or summer break.
What to look for in a quote
- What hours they’ll be on site
- When the next visit should be, and why
- Whether a written report and pictures are included
- Whether a survey comes first
When something else is needed
Some problems need a different service or another trade:
- Ductwork that was designed or installed badly
- The legal duty, which stays with the responsible person
- Mechanical faults in the extract
If you are not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.
