How we handle TR19 inspection in Cothill
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. Our TR19 audits give sites in Cothill and across Oxfordshire a clear record of the system’s condition. Typical jobs include extracts that have never been grease tested and sections of duct that can’t be reached, on deposit thickness tests, pre-clean surveys and insurer audits.
Somewhere as small as Cothill, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why act early in Cothill
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Somewhere as small as Cothill, losing a kitchen or building to a fault is felt by everyone who uses it.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

Managing agents and facilities teams in Cothill
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

What affects the quote in Cothill
The price is fixed before any work begins. It’s based on:
- The times the site is available
- The condition we find in the survey
- The number of sites or systems
- Where the site is and how we reach it
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. Ask for a fixed quote and we will go through it with you.
Helping us quote
You do not need the technical terms. It helps if you can send:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
Need a price for TR19 inspection? Please phone us on 0345 646 2711 or email us with a few details about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. 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. Seeing the system in pictures first means the trip to Cothill can be planned properly.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Advice
Signs you need TR19 inspection in Cothill
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
Most sites get in touch after spotting something like this:
- Insurance renewals needing proof of TR19 cleaning
- Confirming a clean reached the whole system
- Missing access panels found on survey
- Uncertainty over how often to clean
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Appleton Manor is about 1.8 miles north-west), access may need planning.

Staff cleaning versus specialist work
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. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What TR19 inspection can’t fix
It’s worth knowing the limits before booking:
- Fan breakdowns, which need a repair visit
- Heavy deposits found on test, which still need cleaning
- Installation problems, which fall under design guidance such as DW172
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think before you book.

Your questions about TR19 inspection in Cothill
Who enforces fire safety at workplaces in Cothill?
Oxfordshire Fire and Rescue Service is the fire and rescue service for Cothill. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can the work in Cothill be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Cothill can fit around your hours. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
How long does a TR19 inspection take?

What is post-clean verification?
A post-clean check records grease readings and photos after the work, for our cleans and other firms’ alike.

We take it away when we go. During the work, it’s contained so the area stays clean.

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Kitchen extracts in Cothill
According to Food Standards Agency records, there are about 3 bars, pubs and nightclubs within 1.5 miles or so of the middle of Cothill. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Cothill sits within the area of Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Vale of White Horse council that sends environmental health officers to food businesses in Cothill. 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.
School kitchens, at schools like Dry Sandford Primary School for example, are typically cleaned in the holidays so no lunches are lost. A hall kitchen that only cooks for events, whether near Church of St Helen or elsewhere in Cothill, still needs its extract cleaned, just less often.
