What TR19 inspection looks like in Derringstone
Look up Derringstone on the FSA’s food hygiene register and you’ll find about 3 restaurants, cafés and canteens within roughly a mile and a half of the centre of Derringstone. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Kent Fire and Rescue Service covers Derringstone. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Canterbury City council that sends environmental health officers to food businesses in Derringstone. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Healthcare kitchens, like those at hospitals such as Kent and Canterbury Hospital (about 5.3 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Barham Church of England Primary School, an extract clean fits neatly into a half-term or summer break. Where a hall near Church of St John the Baptist, or anywhere in Derringstone, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

TR19 inspection in Derringstone, done properly
Think of a TR19 inspection as the diagnosis before the treatment. Readings, pictures and notes on access are gathered from end to end, so the quote and the clean fit the real system. Typical jobs include sections of duct that can’t be reached and kitchen extract systems with no recent grease readings, on insurer audits, access surveys and post-clean checks.
Work in a small place like Derringstone 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.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Honest limits
We’d rather tell you now than book work that won’t help, so here are the limits:
- Heavy deposits found on test, which still need cleaning
- Sections with no access, until panels are fitted
- Ductwork that was designed or installed badly
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.
What the work covers
- Pre-clean surveys
- Post-clean checks
- Wet film thickness tests
- Deposit thickness tests
- Insurer audits
- Access surveys
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Diary the next grease test and clean
- Share inspection reports with your insurer or broker when asked
- Mention new equipment or longer hours at the next test
- Keep canopy edges and gutters wiped down
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
Why act early in Derringstone
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. With notice, the visit to Derringstone can be fitted around your bookings and events.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

Different parts, different methods
Vertical risers
Risers in multi-storey buildings can pass through other areas, so access is planned in advance.
Extract fan and discharge
A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.
The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. A few photos of the system help us make the most of a visit to a place like Derringstone.
- First we look at the system’s cleaning history, if there is one.
- 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.
- We report back with readings and a fixed quote.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

FAQs for Derringstone
Can a school canteen extract in Derringstone be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Derringstone. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Can you get to a site in Derringstone?
Yes, Derringstone is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Why survey before a clean?
We look at the system from canopy to discharge, take grease readings and check access. It lets us plan the clean and send you a fixed quote.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and TR19® is what insurers and fire officers look to.
How much time does an inspection need?
An inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Sites with several canopies take longer, and you can phone us on 0345 646 2711, or email photos to book it in.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Fixed quotes for TR19 inspection in Derringstone
Some jobs are bigger than they look, and some smaller. The main factors:
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- How many systems or sites are involved
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

To help us quote quickly, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
