About our TR19 inspection in Spring Grove
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’re dealing with extracts that have never been grease tested and insurance renewals needing proof of TR19 cleaning, we can put it right.
In a London area like Spring Grove, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Between visits
Once we’ve finished, these simple steps help:
- Tell us if menus or opening hours change
- Keep canopy edges and gutters wiped down
- Keep the route to access panels clear
- Keep grease filters clean and fitted properly
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
When cooking hours or the menu change, check the interval still fits. Fresh readings show whether it needs to change.
The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Night and weekend working is normal for us in London, and a site in Spring Grove is no exception.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
- Move anything stored near the system

What TR19 inspection can’t fix
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Mechanical faults in the extract
- The legal duty, which stays with the responsible person
- Hidden runs that need access panels first
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Do you need TR19 inspection in Spring Grove?
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Any of these means the system needs a check-up:
- Pre-clean surveys before a first TR19 clean
- Sections of duct that cannot be reached
- Sites with gaps in their extract records
- Confirming a clean reached the whole system
Church and community hall kitchens, near St Mary's Church or anywhere around Spring Grove, are easy to forget, but their extracts collect grease like any other.

Spring Grove questions
Can parking be tricky for a job in Spring Grove?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we will book into it.
Who inspects food businesses in Spring Grove?
In Spring Grove, it’s Hounslow council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do we have to follow TR19 by law?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and insurers, fire officers and EHOs look to TR19® as the benchmark.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What do the grease readings need to be?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
How often should grease be tested?
Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What TR19 inspection looks like in Spring Grove
Look up Spring Grove on the FSA’s food hygiene register and you’ll find about 249 restaurants, cafés and works canteens and about 104 takeaways and sandwich shops within roughly a mile and a half of the centre of Spring Grove. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. It’s Hounslow council that sends environmental health officers to food businesses in Spring Grove. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. London jobs usually start after the last service, with loading and roof access agreed with the building first.
For schools such as Isleworth and Syon School for Boys, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. For kitchens close to Isleworth station, where the day often starts early and ends late, the extract can be cleaned overnight.

What else we do in Spring Grove
Leave it or put it right?
If a kitchen in Spring Grove has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Testing gives you the evidence to set it properly. It’s better booked as a planned job in Spring Grove than handled as an emergency.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
