TR19 inspections and grease testing in Bexley, Greater London
Our technicians work in Bexley on TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Pre-clean surveys before a first TR19 clean
- Heavy grease suspected in the plenum or ducts
- Insurers asking for TR19 evidence
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
TR19 inspection in Bexley
After a clean, post-clean verification checks the result, with new readings and photos of the cleaned areas. It gives you evidence of how the system was actually left. If you’re dealing with parts of the system left out of past cleans and kitchens whose menu or hours have changed, we can help.
In a London area like Bexley, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a morning or less for one kitchen, more where there are several systems, and we clear up before we go. If your building in Bexley has sign-in rules, permits or key holders, mention them when you book.
- The visit is arranged for when the kitchen is not busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, pictures and next steps.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system

Common problems we fix in Bexley
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.
Keep an eye out for any of the following:
- Pre-clean surveys before a first TR19 clean
- Insurers asking for TR19 evidence
- Sections of duct that can’t be reached
- Kitchens taken over with no cleaning records
If you run a church or community hall kitchen, near Parish Church of St John the Evangelist or elsewhere in Bexley, its extract still collects grease from every lunch and event.

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the route to access panels clear
- Book the next test on the date in the report
- Send TR19 audit reports to your insurer on request
- Wipe the canopy surfaces regularly
The audit report is set out to pass straight to your insurer or broker, with readings, pictures and any areas not accessible.
Keep filters clean and in place. Missing or damaged filters let grease straight into the plenum.
TR19 inspection in Bexley: the local picture
Food Standards Agency data counts about 146 cafés, restaurants and staff canteens and about 48 takeaways in and around Bexley, up to about a mile and a half out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Most London extract cleaning happens at night, after the last service. In Bexley, food businesses are inspected by environmental health officers from Bexley council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
Term dates shape school work: for a school like Old Bexley Church of England School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens, like those at hospitals such as Bexley Hospital (about 1 mile north), often cook for long hours, which puts them in BESA’s heavier-use bands.

Do you clean school canteen extracts around Bexley out of term?

What’s TR19?
BESA’s ventilation hygiene 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.
How long does grease testing take?
As a guide, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The size of the system and the access make the difference.
Do you carry out TR19 audits for insurers?
Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. It’s set out for your insurer or broker.
Do you cover Bexley?
Yes. We cover Bexley and the rest of Greater London, within our South East and London area. To book, ring 0345 646 2711 or use the quote form.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Do we have to follow TR19 by law?
No, TR19® isn’t legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.
