TR19 inspection for kitchens and businesses in Sheet Hill
Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, and only measurement shows it. Our readings give your risk assessment real numbers to work from. Typical jobs include surveys needed before quoting a full clean and heavy grease suspected in the plenum or ducts, on insurer audits, post-clean checks and wet film thickness tests.
Somewhere as small as Sheet Hill, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What a clean will not put right
To be straight with you, some problems need a different fix:
- Sections with no access, until panels are fitted
- A faulty or failing extract fan
- Removing the grease, which is a separate clean
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before booking.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
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.
Grease, kitchens and Sheet Hill
The FSA’s food hygiene register includes about 8 bars, pubs and nightclubs across Sheet Hill and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from Tonbridge and Malling council inspect food businesses in Sheet Hill. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Sheet Hill falls to Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Volunteers running a hall kitchen near Plaxtol Church, or anywhere in Sheet Hill, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Sheet Hill is Sevenoaks Hospital, about 4.4 miles west. Old Soar Manor, about 1.3 miles east, is one of the historic houses near Sheet Hill; if you run event catering at a venue like that, cleans can be booked between functions.

Fixed quotes for TR19 inspection in Sheet Hill
The survey tells us what the work involves. We look at:
- One-off work versus a regular cycle
- How many systems or sites are involved
- What state the system is in
- The size of the system
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
What to send for a quote
To speed up the quote, please include:
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
FAQs for Sheet Hill
Who carries out food hygiene inspections in Sheet Hill?
The local authority for Sheet Hill is Tonbridge and Malling council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Is Sheet Hill within the area you cover?
Yes, we work in villages as well as towns, and Sheet Hill is covered. The journey is planned ahead, so a few details about the route help.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
What grease levels does TR19 allow?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What is a WFTT or DTT grease test?
We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Aftercare tips
After the visit, a few habits help the work last:
- Book the next test on the date in the report
- Store grease readings where your insurer can see them
- Tell us if menus or opening hours change
- Clean or swap grease filters as often as the kitchen needs
You get a report with the grease readings, where they were taken and photos of each point. Keep it with your fire safety and TR19 records.
Keep filters clean and in place. Gaps around filters let grease get past them.
What happens if it’s left?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Our emergency line runs 24/7, but a planned visit to Sheet Hill is calmer for everyone.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

Places near Sheet Hill
What else we do in Sheet Hill
Part by part
Canopy and plenum
The canopy itself is checked inside and out, with readings where grease collects.
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. We agree a date with you, plan the drive to Sheet Hill and turn up when the site is quiet.
- The visit is arranged for when the kitchen is not busy.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, pictures and a recommended next clean.
Getting ready for the visit
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
