TR19 inspection in Blackthorn
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 clean can be planned properly. Common call-outs are for sites with gaps in their extract records and parts of the system left out of past cleans, across access surveys, insurer audits and pre-clean surveys.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
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 are happy to quote for all of it.
Part by part
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. That’s why we test behind them.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, with testing showing whether more is needed.

How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a couple of hours for a typical kitchen extract system. Seeing the system in pictures first means the trip to Blackthorn can be planned properly.
- We agree a time when the kitchen is closed or quiet.
- Every part of the system is examined, end to end.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, pictures and next steps.
Before we arrive
- Clear loose items from the work area
- Dig out any earlier paperwork for the system
- Name a contact who can let us in at the agreed time
Ask for a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Between visits
Once we have finished, these simple steps help:
- Share inspection reports with your insurer or broker when asked
- Wipe the canopy surfaces regularly
- Tell us if menus or opening hours change
- Keep TR19 certificates, readings and reports together
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
What happens if it’s left?
If a kitchen in Blackthorn has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Measured readings let a competent person set the interval. In a place like Blackthorn, ductwork and fans are easy to forget until something goes wrong.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

What a clean will not put right
In fairness, some problems need a different fix:

FAQs for Blackthorn
Can a school canteen extract in Blackthorn be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Blackthorn. Send us your term dates when you phone us on 0345 646 2711, or email photos, and we’ll fit the work in.
Do you cover smaller places like Blackthorn?
Yes. Villages and rural sites across the South East are part of our work, Blackthorn included. A survey first, from photos or a visit, means we arrive with the right kit.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How long does a TR19 inspection take?
It takes a couple of hours for a typical kitchen extract system. We fit it around when the kitchen is closed or quiet.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How much does TR19 inspection cost in Blackthorn?

What affects the quote in Blackthorn
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access, including roofs, risers and ceiling voids
- The condition of the system
- Site rules, permits and inductions
- When the work can happen, such as evenings, overnight or weekends
You will not 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.
What to send for a quote
When you contact us, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- Any previous report or certificate
To get a fixed quote, ring 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.
Grease, kitchens and Blackthorn
There are about 3 restaurants, cafés and works canteens within about 1.5 miles of central Blackthorn, according to the Food Standards Agency’s register. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Blackthorn 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. Kitchens in Blackthorn get their food hygiene inspections from Cherwell council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
A hall kitchen that only cooks for events, whether near Church of St Mary the Virgin or elsewhere in Blackthorn, still needs its extract cleaned, just less often. For schools such as Five Acres Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Boarstall Tower is about 3.3 miles south), access may need planning.
