Your questions about TR19 inspection in Furzedown
Do you work overnight in Furzedown?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
What do you need to know about parking in Furzedown?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
What is grease thickness testing?
WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.
What grease levels does TR19 allow?
Between cleans, the mean should stay at 200 microns or below, with 500 microns or more anywhere needing immediate spot cleaning.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Can you verify a clean after it’s been done?
After a clean, we take new readings and photos to show how the system was left. It can follow our own cleans or another contractor’s.
Why survey before a clean?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Missing access panels are noted ahead of the clean.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
About our TR19 inspection in Furzedown
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. Typical jobs include extracts that have never been grease tested and missing access panels found on survey, across wet film thickness tests, post-clean checks and insurer audits.
In a London area like Furzedown, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
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.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Share inspection reports with your insurer or broker when asked
- Store grease readings where your insurer can see them
- Flag oily drips near the extract
- Keep canopy edges and gutters wiped down
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can arrange it.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes around an hour or two per canopy and duct system. Most London sites cannot stop for the day, so work in Furzedown is normally done overnight, early in the morning or at weekends.
- First we book a time that will not disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one

Kitchen extracts in Furzedown
Food Standards Agency data counts about 447 restaurants, cafés and canteens and about 117 takeaways within about 1.5 miles of central Furzedown. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Most London extract cleaning happens at night, after the last service. Fire safety in Furzedown falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
School kitchens, at schools like Graveney School for example, are normally cleaned in the holidays so no lunches are lost. If you cook for passing trade around Tooting station, the extract can be cleaned between your last and first customer.

What affects the quote in Furzedown
We quote each job individually. These are the things that affect it:
- How big the system is
- What state the system is in
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or use the quote form.
Do you need TR19 inspection in Furzedown?
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
The symptoms we are asked about most include:
- Surveys needed before quoting a full clean
- Extracts that have never been grease tested
- Sections of duct that cannot be reached
- Extracts that may be over the 200 micron mean
If you run a church or community hall kitchen, near St Paul's Church or elsewhere in Furzedown, its extract still collects grease from every lunch and event.

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 Furzedown a current picture. Every month a London system goes without attention adds to what has to be done later.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
