About our TR19 inspection in Colliers Wood
Think of a TR19 inspection as the diagnosis before the treatment. Readings, pictures and notes on access are gathered from end to end, so the quote and the clean fit the real system. The work covers insurer audits, post-clean checks and wet film thickness tests, and common reasons people get in touch are insurance renewals needing proof of TR19 cleaning and ductwork where grease may be over the TR19 limits.
Kitchens in Colliers Wood, 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. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Questions from Colliers Wood
Is parking a problem for work in Colliers Wood?
Tell us where a van can stop near your site in Colliers Wood, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Can you work in Colliers Wood outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Colliers Wood needn’t be disturbed. Just give us a ring on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What do you do with what you remove?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
How do you measure grease in a kitchen extract?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
How often should grease be tested?
Often enough to know the mean stays under 200 microns between cleans. If readings rise, the interval should shorten.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Is Colliers Wood in your area?
Yes. Colliers Wood is part of the area we cover, within the South East and London area we cover.
When something else is needed
We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Hidden runs that need access panels first
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
What the work covers

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Between visits
Aftercare is simple, and it helps at the next visit:
- Diary the next grease test and clean
- Flag changes in how much frying the kitchen does
- Don’t box in or cover duct access panels
- File every inspection report with your certificates
For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.
When cooking hours or the menu change, check the interval still fits. Fresh readings show whether it needs to change.

What TR19 inspection looks like in Colliers Wood
The Food Standards Agency lists about 39 bars, pubs and nightclubs and about 6 hotels, B&Bs and guest houses as registered food businesses in and around Colliers Wood, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Colliers Wood falls to London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. It’s Wandsworth council that sends environmental health officers to food businesses in Colliers Wood. 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.
Bursars and site managers at schools such as Sellincourt Primary School tend to book extract cleaning for when the kitchen is empty. A kitchen near Tooting station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Grove Hospital is the nearest hospital to Colliers Wood, about 0.6 miles north.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes an hour or two for a single kitchen, longer for a large or complex system. Expect the work in Colliers Wood to happen after your last customer leaves, not during trading.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Move anything stored near the system
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, call 0345 646 2711 or drop us a line.
Advice
Leave it or put it right?
A check after cleaning shows whether the work reached every part it should have, before the next clean is due. It’s better booked as a planned job in Colliers Wood than handled as an emergency.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

Part by part
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and pictures are taken in the plenum on every inspection.
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.
