TR19 inspection in Twitton
Think of a TR19 inspection as the diagnosis before the treatment. We look at the system, take grease readings and photograph what we find, so the quote and the clean fit the real system. We are often asked to deal with systems that need surveying before cleaning and post-clean verification after another contractor’s clean, across post-clean checks, wet film thickness tests and insurer audits.
Work in a small place like Twitton starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:
- Fan breakdowns, which need a repair visit
- The responsible person’s own fire risk assessment
- Installation problems, which fall under design guidance such as DW172
If you’re not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer before you book.

What else we do in Twitton
What TR19 inspection looks like in Twitton
There are about 4 restaurants, cafés and canteens across Twitton and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Each kitchen extract among them can be measured for grease to set the right cleaning interval. It’s Sevenoaks council that sends environmental health officers to food businesses in Twitton. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Twitton is Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Volunteers running a hall kitchen near Twitton Mission Church, or anywhere in Twitton, may not know when the extract was last cleaned, and a grease test settles it. If you look after a school kitchen, at a school such as Otford Primary School or anywhere near Twitton, the holidays are the usual time for a TR19® clean. Lullingstone Castle, about 3.3 miles north, is one of the historic houses near Twitton; if you run event catering at a venue like that, cleans can be booked between functions.
Twitton is about 2 miles north of Sevenoaks, in Kent.

How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes around an hour or two per canopy and duct system. A quick note on how to find the site and where to park makes a visit to Twitton run smoothly.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Tell us where we can park and unload
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time

Related advice
Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Part by part
Schools, hospitals and care homes
School and college kitchens still need their extract checked. Testing shows whether the interval suits.
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, with testing showing whether more is needed.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Flag oily drips near the extract
- Mention new equipment or longer hours at the next test
- File every inspection report with your certificates
- Share inspection reports with your insurer or broker when asked
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Fit access panels where the survey finds sections can’t be reached, so grease is not left building in hidden parts.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
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 on a regular cycle.
How we price TR19 inspection
You’ll get a fixed price before work begins. It takes into account:
- How easy every part is to reach
- How many systems or sites are involved
- The condition we find in the survey
- Where the site is and how we reach it
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- Your last certificate, test record or report
- Where the site is and what kind of site it is
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.
Questions from Twitton
Do you work in villages like Twitton?
Yes, we work in villages as well as towns, and Twitton is covered. The journey is planned ahead, so a few details about the route help.
Can you clean school kitchen extracts in Twitton during the holidays?
Yes, out-of-term visits are normal for schools. With about 6 schools and colleges on the FSA’s register within roughly a mile and a half of Twitton, it pays to plan holiday dates ahead. You can call 0345 646 2711 or send us an email with the dates the site is empty.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
How often should grease be tested?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. The interval should come from a competent person’s risk assessment backed by grease measurement.
How much does TR19 inspection cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
