How we handle TR19 inspection in Force Green
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. The work covers insurer audits, deposit thickness tests and pre-clean surveys, and common reasons people get in touch are confirming a clean reached the whole system and an insurer’s request for a TR19 audit.
In a London area like Force Green, 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.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What we’re called out for in Force Green
You cannot judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
What we are most often called out for:
- Insurers asking for TR19 evidence
- Cleaning intervals that may not suit the kitchen
- Parts of the system left out of past cleans
- Post-clean verification after another contractor’s clean
Church and community hall kitchens, near Church of St Mary the Virgin or anywhere around Force Green, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- How they set the interval to the next visit
- Which accreditations they hold, and whether you can check them
- Whether inaccessible sections are listed on the report
- Whether VAT is included
TR19 inspection in Force Green: the local picture
There are about 19 restaurants, cafés and canteens and about 10 takeaways and sandwich shops in Force Green and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Force Green sits within the area of London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If your kitchen is in a listed or historic building, like the houses around Force Green (Quebec House is about 0.8 miles south), fitting access panels needs care. Healthcare kitchens, like those at hospitals such as Tandridge Priory (about 2.7 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Report grease dripping from the canopy
- Keep grease filters clean and fitted properly
- File every inspection report with your certificates
- Do not box in or cover duct access panels
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
How we price TR19 inspection
Your quote is based on your site. We take into account:
- How big the system is
- Travel, parking and unloading
- Whether several sites go on one quote
- Any permits to work or inductions
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Why it’s worth doing now in Force Green
Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. Every month a London system goes without attention adds to what has to be done later.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
Why choose Duct Doctor in Force Green
- Out-of-hours work and a 24/7 emergency line

FAQs for Force Green
Who enforces fire safety at workplaces in Force Green?
Fire safety enforcement in Force Green is handled by London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who carries out food hygiene inspections in Force Green?
The local authority for Force Green is Sevenoaks council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
What grease levels does TR19 allow?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can you work evenings and weekends?
Yes. Much of our work happens in the evening, overnight or at weekends, so the site does not lose a service.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Getting kit into a London building takes planning, so let us know where we can load and park in Force Green.
- First we book a time that will not disrupt cooking.
- The system is checked from canopy to 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, pictures and next steps.
How to prepare
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
