TR19 inspection in Offham, done properly
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. The work covers pre-clean surveys, deposit thickness tests and insurer audits, and the jobs we see most are heavy grease suspected in the plenum or ducts and kitchen extract systems with no recent grease readings.
For a kitchen in or near Offham, the visit is planned around opening hours and the journey, 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.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
What we’re called out for in Offham
Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.
Any of these means the system needs a check-up:
- Uncertainty over how often to clean
- Post-clean verification after another contractor’s clean
- Kitchens taken over with no cleaning records
- Missing access panels found on survey
Term dates shape school work: for a school like Offham Primary School, an extract clean fits neatly into a half-term or summer break.
Questions to ask before booking
- What paperwork you get at the end
- How VAT is shown on the quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether they’re fully insured
Between visits
Think of this as the after-treatment advice, in brief:
- Tell us if menus or opening hours change
- Keep to the recommended interval
- Send TR19 audit reports to your insurer on request
- Report grease dripping from the canopy
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
Questions from Offham
Who enforces fire safety at workplaces in Offham?
It’s Kent Fire and Rescue Service, which covers Offham. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you come to Offham after we close?
Yes, we can come after you close and finish before you open. It means the site in Offham keeps running as normal. Your opening times are the first thing we ask for.
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 accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Will you produce a report for our insurer?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
What does TR19 inspection cost?
It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711 or use the quote form with the site type, opening hours and a few photos.
What does a pre-clean survey involve?
We survey, measure and photograph the system first. The survey can be done from pictures and details or on site, as suits the job.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then phone us on 0345 646 2711 or email us.
What TR19 inspection looks like in Offham
According to Food Standards Agency records, there are about 15 pubs and bars within 1.5 miles or so of the middle of Offham. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Offham get their food hygiene inspections from Tonbridge and Malling council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Offham falls to Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Church and community hall kitchens, near Church of St Michael or anywhere around Offham, are easy to forget, but their extracts collect grease like any other. A hospital like Maidstone Hospital, about 4.8 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

How we price TR19 inspection
You’ll get a fixed price before any work starts. It’s based on:
- Where the site is and how we reach it
- How easy every part is to reach
- The times the site is available
- One-off work versus a regular cycle
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.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Part by part
Extract fan and discharge
The discharge at the end of the system is checked as well, since grease reaches the very end of the system.
Schools, hospitals and care homes
In healthcare and care settings, kitchens may run from early until late. Readings show if cleaning is frequent enough.
What happens on the day
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. The timing of a visit to Offham is set by you, and the travel is our side of the planning.
- Post-clean verification is booked once the clean is done.
- 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.
Before we arrive
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
