TR19 inspection for kitchens and businesses in Clerkenwell
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you’re on. We are often asked to deal with post-clean verification after another contractor’s clean and sites with gaps in their extract records, across pre-clean surveys, post-clean checks and wet film thickness tests.
Kitchens in Clerkenwell, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Between visits
Simple habits between visits make a real difference. We recommend:
- Flag oily drips near the extract
- Share inspection reports with your insurer or broker when asked
- Diary the next grease test and clean
- Keep canopy edges and gutters wiped down
The audit report is set out to pass straight to your insurer or broker, including readings, photos and any inaccessible sections.
Fit access panels where the survey finds sections can’t be reached, so grease is not left building in hidden parts.
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes around an hour or two per canopy and duct system. Night and weekend working is normal for us in London, and a site in Clerkenwell is no exception.
- 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.
- We report the findings and flag any areas that need more work.
Getting ready for the visit
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in

Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
Advice
Grease, kitchens and Clerkenwell
The Food Standards Agency lists about 519 pubs and bars and about 165 hotels and B&Bs as registered food businesses in and around Clerkenwell, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. Clerkenwell 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.
Where a hall near St James's Church, or anywhere in Clerkenwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does. A kitchen near Farringdon station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
Clerkenwell is about 2 miles north of London, in Greater London. Sites in Clerkenwell get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Clerkenwell is one of 764 towns, villages and districts in Greater London where we work for TR19 inspection.
Here we cover the N1, EC1V and WC1X postcode area for TR19 inspection. If you need TR19 inspection at premises on Long Lane, City Road and Noel Road or a nearby road, our technicians can take on the work.

In Clerkenwell, that means kitchens and buildings near Barts Health Archives, The Sekforde pub and Elizabeth Garrett Anderson School. Nearby too are Tech City College (within half a mile north-east) and King Square Gardens (under half a mile north-east). Clerkenwell has its own railway station: Farringdon station.

What we are called out for in Clerkenwell
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
Any of these means the system needs a check-up:
- Parts of the system left out of past cleans
- Post-clean verification after another contractor’s clean
- Heavy grease suspected in the plenum or ducts
- Uncertainty over how often to clean
For schools such as St Peter and St Paul RC Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

FAQs for Clerkenwell
Do you work at weekends in Clerkenwell?
Yes, evening, overnight and weekend work is normal for us. That way a site in Clerkenwell doesn’t have to lose a day’s trading. Just ring 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Who is the fire and rescue service for Clerkenwell?
Clerkenwell is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What is post-clean verification?
After a clean, we take new readings and pictures to show how the system was left. It works whoever carried out the clean.
How do you measure grease in a kitchen extract?
We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.
How much does TR19 inspection cost in Clerkenwell?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
How long does grease testing take?
An inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Large or multiple systems take longer, and you can call 0345 646 2711 or email us to book it in.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What the work involves, part by part
Canopy and plenum
Clean-looking filters don’t mean a clean plenum. So we measure behind the filters, not just in front.
Vertical risers
Risers in multi-storey buildings can pass through other areas, so access is planned in advance.
When something else is needed
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Sections with no access, until panels are fitted
- The legal duty, which stays with the responsible person
- A faulty or failing extract fan
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before booking.
