Greater London · TR19 inspections and grease testing
Victoria TR19 inspection
TR19 inspection in Victoria from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Ductwork where grease may be over the TR19 limits
- Uncertainty over how often to clean
- Post-clean verification after another contractor’s clean
How we handle TR19 inspection in Victoria
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Grease testing shows which side of those lines you are on. We’re often asked to deal with ductwork where grease may be over the TR19 limits and confirming a clean reached the whole system, on insurer audits, access surveys and pre-clean surveys.
London kitchens tend to trade late and open early, so work in Victoria is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

When it’s something else
TR19 inspection cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Hidden runs that need access panels first
- Installation problems, which fall under design guidance such as DW172
- Mechanical faults in the extract
If you are not sure, just call 0345 646 2711 or email us and we will give you a straight answer before you book.

Common questions in Victoria
Who inspects food businesses in Victoria?
The local authority for Victoria is Westminster council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can school kitchens in Victoria be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Around Victoria, the Food Standards Agency lists about 58 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711 or drop us a line, and we will fit the work in.
What happens on a pre-clean survey?
The survey covers the whole system, grease readings and access to each section. It lets us plan the clean and send you a fixed quote.
Do you check other contractors’ cleans?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It can follow our own cleans or another contractor’s.
What information do you need?
A short description and a few pictures plus the address and your hours. We will ask for anything else we need.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you work evenings and weekends?
Yes, and it’s often the best time. We book the visit for when the area is out of use, whether that is late evening, overnight or a weekend.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Different parts, different methods
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. They’re included in the readings and pictures.
Vertical risers
Risers in multi-storey buildings can pass through other areas, so access is planned in advance.
Kitchen extracts in Victoria
There are about 2,776 restaurants, cafés and works canteens and about 228 takeaways and sandwich shops within roughly a mile and a half of the centre of Victoria, according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Food hygiene inspections in Victoria are the job of Westminster council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Victoria sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run catering at a healthcare site, such as a hospital like Westminster Children's Hospital about less than half a mile south-east, the extract may need cleaning more often than a part-time kitchen. Church and community hall kitchens, near St. Michael's Church or anywhere around Victoria, are easy to forget, but their extracts collect grease like any other. Bursars and site managers at schools such as St Peter's Eaton Square CofE Primary School tend to book extract cleaning for when the kitchen is empty.

What else we do in Victoria
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a couple of hours for a typical kitchen extract system. Before any visit in Victoria, we agree where the van can stop and how equipment reaches the system.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
How to prepare
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
Ask for a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or email us.

Fixed quotes for TR19 inspection in Victoria
We quote each job individually. These are the things that affect it:
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- Travel, parking and unloading
- How many systems or sites are involved
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
What we need to know
When you call or email, it’s useful to have:
- How we’d reach plant on a roof or in a plant room

Want a quote for TR19 inspection? Please call us on 0345 646 2711 or send us an email with a few details about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Book the next test on the date in the report
- Send TR19 audit reports to your insurer on request
- Clean grease off the canopy between professional cleans
- Flag changes in how much frying the kitchen does
After the inspection, we send a report showing each reading, its location and pictures. Keep it with your fire safety and TR19 records.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
Why deal with it now?
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. An inspection now gives a site in Victoria a current picture. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.
