TR19 inspection for kitchens and businesses in Bentley
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Without it, a claim can be refused or reduced. Our TR19 audits give sites in Bentley and across Surrey a clear record of the system’s condition. The work covers wet film thickness tests, insurer audits and post-clean checks, and common reasons people get in touch are insurers asking for TR19 evidence and pre-clean surveys before a first TR19 clean.
For a kitchen in or near Bentley, the visit is planned around opening hours and the journey, 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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
TR19 inspection around Bentley
At about 40 miles from central London, Bentley sits well inside the area we cover. The visit is fixed around your opening hours, not ours. It’s East Hampshire council that sends environmental health officers to food businesses in Bentley. 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.
A kitchen near Bentley (Hampshire) station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you look after a school kitchen, at a school such as Bentley Church of England Primary School or anywhere near Bentley, the holidays are the usual time for a TR19® clean.

What happens if it’s left?
Without readings, you’re guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you will not know without measuring. Our emergency line runs 24/7, but a planned visit to Bentley is calmer for everyone.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.

What affects the quote in Bentley
Your quote is based on your site. We take into account:
- The condition we find in the survey
- Travel, parking and unloading
- A single visit or a regular plan
- The size of the system
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Photos showing the whole system and its surroundings
If you need TR19 inspection in Bentley, give us a ring on 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote typically follows within one working day.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes a morning or less for one kitchen, more where there are several systems. A quick note on how to find the site and where to park makes a visit to Bentley run smoothly.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload

What else we do in Bentley
Common questions in Bentley
Do you work in villages like Bentley?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Who is the fire and rescue service for Bentley?
Fire safety enforcement in Bentley is handled by Surrey Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
At what point does grease need cleaning?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning straight away.
What is post-clean verification?
Verification means repeat readings and pictures once the clean is done. Any areas that weren’t cleaned properly are flagged.
How often should grease be tested?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Missing access panels are noted ahead of the clean.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and insurers, fire officers and EHOs look to TR19® as the benchmark.
How the job changes from site to site
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.
Signs you need TR19 inspection in Bentley
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.
What we’re most often called out for:
- Pre-clean surveys before a first TR19 clean
- Kitchen extract systems with no recent grease readings
- Ductwork where grease may be over the TR19 limits
- Post-clean verification after another contractor’s clean
A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in Bentley, still needs its extract cleaned, just less often.
Questions to ask before you book
- How VAT is shown on the quote
- When the next visit should be, and why
- Proof of insurance
- Whether the figure could change on the day
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Diary the next grease test and clean
- Keep the route to access panels clear
- Send TR19 audit reports to your insurer on request
- Clean grease off the canopy between professional cleans
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Test grease regularly instead of relying on the calendar. It spots changes in how fast grease builds.
