About our TR19 inspection in Carpenders Park
A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and record grease readings at set points. The work covers pre-clean surveys, deposit thickness tests and insurer audits, and the jobs we see most are extracts that have never been grease tested and heavy grease suspected in the plenum or ducts.
In London, few kitchens can spare a day to close, so work in Carpenders Park is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What a clean won’t put right
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Removing the grease, which is a separate clean
- Parts of the duct nobody can reach yet
- Mechanical faults in the extract
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think before booking.

TR19 inspection around Carpenders Park
There are about 48 cafés, restaurants and staff canteens and about 13 takeaways within 1.5 miles or so of the middle of Carpenders Park, according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. London Fire Brigade covers Carpenders Park. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Most London extract cleaning happens at night, after the last service.
If you run a café or takeaway near Carpenders Park station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Volunteers running a hall kitchen near Oxhey Chapel, or anywhere in Carpenders Park, may not know when the extract was last cleaned, and a grease test settles it.

The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes an hour or two for a single kitchen, longer for a large or complex system, and we clear up before we go. Loading bays, visitor permits and roof access are the first things we ask about for a site in Carpenders Park.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- You get a report and a fixed quote for the clean.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Move anything stored near the system
- Let us know about parking and loading
Getting a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.

Leave it or put it right?
Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. For a site in Carpenders Park, fitting the work in overnight now is far easier than closing at short notice later.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

Do you need TR19 inspection in Carpenders Park?
Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.
Any of these means the system needs a check-up:
- Missing TR19 certificates or history
- Systems that need surveying before cleaning
- Insurance renewals needing proof of TR19 cleaning
- Sections of duct that cannot be reached
For schools such as St Meryl School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
What to look for in a quote
- Whether the work can be done while the site is closed
- What insurance they carry
- Proof of accreditation you can verify
- If the quote is a fixed price or an estimate
What affects the quote in Carpenders Park
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles

What your team can do, and what needs us
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.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
FAQs for Carpenders Park
Do you work overnight in Carpenders Park?
Yes, we can come after you close and finish before you open. It means the site in Carpenders Park keeps running as normal. Your opening times are the first thing we ask for.
Which fire service covers Carpenders Park?
It’s London Fire Brigade, which covers Carpenders Park. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Is TR19 a legal requirement?
No. TR19® isn’t law; it’s BESA’s specification. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.
What is a WFTT or DTT grease test?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What does TR19 inspection cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, typically ready within one working day.
At what point does grease need cleaning?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
