TR19 inspections in Bierton
TR19 inspection for Bierton, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.

When to call us in Bierton
When a site in Bierton changes owner or cleaning contractor, the records don’t always follow. With no history, the current state of the extract is a guess.
Keep an eye out for these warning signs:
- Insurance renewals needing proof of TR19 cleaning
- Kitchen extract systems with no recent grease readings
- Pre-clean surveys before a first TR19 clean
- Post-clean verification after another contractor’s clean
Healthcare kitchens, like those at hospitals such as Tindal Centre (about 1 mile south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

How we handle TR19 inspection in Bierton
A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. The work covers deposit thickness tests, post-clean checks and access surveys, and common reasons people get in touch are sections of duct that can’t be reached and kitchens whose menu or hours have changed.
Somewhere as small as Bierton, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and we clear up before we go. A quick note on how to find the site and where to park makes a visit to Bierton run smoothly.
- The visit is arranged for when the kitchen isn’t busy.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- You get a report with readings, pictures and recommendations.
Getting ready for the visit
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
Ask for a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, call 0345 646 2711 or drop us a line.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

TR19 inspection in Bierton: the local picture
The FSA’s food hygiene register includes about 22 pubs and bars within about 1.5 miles of central Bierton. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Bierton are the job of Buckinghamshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand. Bierton is covered by 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.
If you look after a school kitchen, at a school such as Bierton Church of England Combined School or anywhere near Bierton, the holidays are the usual time for a TR19® clean. Where a hall near Church of St James, or anywhere in Bierton, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Aftercare tips
After the visit, a few habits help the work last:
- Share inspection reports with your insurer or broker when asked
- Mention new equipment or longer hours at the next test
- Flag oily drips near the extract
- Clean grease off the canopy between professional cleans
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can quote to do it.
Fit access panels where the survey finds sections can’t be reached, so grease is not left building in hidden parts.
Why it’s worth doing now in Bierton
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. Equipment tucked in a roof space or outbuilding near Bierton rarely gets looked at unless someone books it.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Different parts, different methods
Extract fan and discharge
Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
Vertical risers
Vertical risers take the extract up through the floors. Grease can run down and collect at the base, so the base is a key test point.
Your questions about TR19 inspection in Bierton
Can you come to Bierton after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Bierton keeps running as normal. Let us know the hours you’re closed and we will book within them.
Do you do school kitchen extract cleaning in Bierton in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bierton. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
What is a WFTT or DTT grease test?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
How much does TR19 inspection cost in Bierton?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
Can you inspect our extract for our insurance company?
Yes. We inspect the system and produce a report with grease readings, pictures and any inaccessible areas. It’s set out for your insurer or broker.
How often should grease be tested?
Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
