TR19 inspections in Lisson Grove
TR19 inspection for Lisson Grove, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Parts of the system left out of past cleans
- Missing TR19 certificates or history
- Extracts that may be over the 200 micron mean
How we handle TR19 inspection in Lisson Grove
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. The work covers access surveys, post-clean checks and insurer audits, and the jobs we see most are missing TR19 certificates or history and kitchens whose menu or hours have changed.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Lisson Grove, that usually means a longer system to clean and more access panels to plan around.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. In a London area like Lisson Grove, parking, loading and building access are planned before the day of the work.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- 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.
Before we arrive
- Clear the space around the work
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload

Grease, kitchens and Lisson Grove
There are about 1,570 restaurants, cafés and works canteens and about 288 sandwich bars and takeaways across Lisson Grove and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. The fire and rescue service for Lisson Grove is London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
If you run a café or takeaway near London Marylebone station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. If you run a church or community hall kitchen, near St Paul's Community Church or elsewhere in Lisson Grove, its extract still collects grease from every lunch and event.

Fixed quotes for TR19 inspection in Lisson Grove
A fixed price needs a few facts first. We look at:
- The size of the system
- Travel, parking and unloading
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
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 the price is fixed before we start.
What we need to know
When you contact us, these details help:
- Any previous report or certificate
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- Wide pictures of the system and the area around it
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Common problems we fix in Lisson Grove
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Most sites get in touch when they notice something like this:
- Extracts that may be over the 200 micron mean
- Post-clean verification after another contractor’s clean
- Insurers asking for TR19 evidence
- Systems that need surveying before cleaning
If you run catering at a healthcare site, such as a hospital like Maida Vale Hospital for Nervous Diseases about 0.5 miles west, the extract may need cleaning more often than a part-time kitchen.
Comparing quotes

Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Questions from Lisson Grove
Who would carry out a food hygiene inspection at a kitchen in Lisson Grove?
Food hygiene inspections in Lisson Grove are carried out by Westminster council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you work overnight in Lisson Grove?
Yes, out-of-hours work is a big part of what we do. The work in Lisson Grove can fit around your hours. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
What does TR19 inspection cost?
It depends on the site, so we quote each one individually. To get one, call us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
What happens on a pre-clean survey?
We check the layout, the grease levels and the access, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
Can you inspect our extract for our insurance company?
Yes, anywhere in the area we cover. Share the insurer’s request so the report addresses it.
When should we have our next grease test?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
What is a WFTT or DTT grease test?
Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.
Honest limits
TR19 inspection can’t fix everything, and we will tell you before work begins. It doesn’t solve:
- Installation problems, which fall under design guidance such as DW172
- A faulty or failing extract fan
- The grease itself, which needs a full or spot clean
If you’re not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer.
Where we work
- Deposit thickness tests
- Wet film thickness tests
- Insurer audits
- Access surveys
- Pre-clean surveys
- Post-clean checks
Leave it or put it right?
Sites in Lisson Grove that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. In Lisson Grove, a planned overnight visit is much easier than closing unexpectedly.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
