Your questions about TR19 inspection in Lee Gate
Which environmental health team covers Lee Gate?
Kitchens in Lee Gate 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.
Who enforces fire safety at workplaces in Lee Gate?
Buckinghamshire Fire and Rescue Service is the fire and rescue service for Lee Gate. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you check other contractors’ cleans?
A post-clean check records grease readings and photos after the work, whoever did the clean.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
At what point does grease need cleaning?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
Do you work out of hours?
Yes. Give us your opening hours with your enquiry and we’ll plan the visit around them.
What is grease thickness testing?
We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.
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 it takes a risk-based approach.
TR19 inspection in Lee Gate
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. We’re often asked to deal with sections of duct that can’t be reached and confirming a clean reached the whole system, on access surveys, insurer audits and pre-clean surveys.
In a small place like Lee Gate, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Lee Gate is 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.

A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Don’t box in or cover duct access panels
- Store grease readings where your insurer can see them
- Keep grease filters clean and fitted properly
- Share inspection reports with your insurer or broker when asked
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Fit access panels where the survey finds sections can’t be reached, so grease isn’t left building in hidden parts.
Do you need TR19 inspection in Lee Gate?
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Most sites get in touch after spotting one of these:
- Missing access panels found on survey
- Checking the result of a recent clean
- Heavy grease suspected in the plenum or ducts
- Pre-clean surveys before a first TR19 clean
A hospital like Chiltern Hospital, about 3.5 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.
Horizontal duct runs
Grease can gather thickly at bends and along long runs, out of sight of the kitchen.
Why it’s worth doing now in Lee Gate
Sites in Lee Gate that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. Planning a trip to Lee Gate ahead is easier for everyone than a rushed one.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.
