TR19 inspection for kitchens and businesses in Lessness Heath
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Lessness Heath and across Greater London a clear record of the system’s condition. Typical jobs include an insurer’s request for a TR19 audit and uncertainty over how often to clean, on post-clean checks, deposit thickness tests and access surveys.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Lessness Heath, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What TR19 inspection looks like in Lessness Heath
According to Food Standards Agency records, there are about 25 bars, pubs and nightclubs within 1.5 miles or so of the middle of Lessness Heath. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. London jobs usually start after the last service, with loading and roof access agreed with the building first. Kitchens in Lessness Heath get their food hygiene inspections from Bexley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you cook for passing trade around Belvedere station, the extract can be cleaned between your last and first customer. If you run catering at a healthcare site, such as a hospital like Erith and District Hospital about 0.9 miles south-east, the extract may need cleaning more often than a part-time kitchen.
Lessness Heath is about 3 miles east of Plumstead, in Greater London. From the centre of Lessness Heath to the outskirts, TR19 inspection is available to all kinds of commercial premises, from a single unit to a large public building.

When to call us in Lessness Heath
As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
Any of these means the system needs a check-up:
- Systems that need surveying before cleaning
- An insurer’s request for a TR19 audit
- Extracts that have never been grease tested
- Cleaning intervals that may not suit the kitchen
A hall kitchen that only cooks for events, whether near Parish Church of All Saints or elsewhere in Lessness Heath, still needs its extract cleaned, just less often.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Lessness Heath.
- 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.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Move anything stored near the system
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet

Advice
Different parts, different methods
Schools, hospitals and care homes
We fit testing around service times and school holidays to avoid disruption.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. We take readings there and photograph it as part of every survey.
Managing agents and facilities teams in Lessness Heath
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Diary the next grease test and clean
- Look out for grease drips round the canopy edge
- Keep grease filters clean and fitted properly
- Keep TR19 certificates, readings and reports together
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
When cooking hours or the menu change, check the interval still fits. Fresh readings show whether it needs to change.
Lessness Heath: your questions answered
Do you work overnight in Lessness Heath?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Lessness Heath needn’t be disturbed. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Can a school canteen extract in Lessness Heath be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 29 schools, colleges and universities with registered kitchens within about a mile and a half of Lessness Heath. Booking early in the term gives the best choice of holiday dates.
What grease levels does TR19 allow?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What if parts of the system can’t be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What’s 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 expects a risk-based approach.
Do you cover Lessness Heath?
Yes. Our technicians work in Lessness Heath, as part of our area across London and the South East.
How often should grease be tested?
It depends on how heavily the kitchen cooks. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.
What happens if it’s left?
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. A recent inspection report means you’re ready when asked. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
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.
