TR19 inspection for kitchens and businesses in Bow
TR19® Grease says grease should not exceed a mean of 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. If you have ductwork where grease may be over the TR19 limits and parts of the system left out of past cleans, we can put it right, from insurer audits, wet film thickness tests and pre-clean surveys onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Signs you need TR19 inspection in Bow
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Common reasons sites call us are:
- Pre-clean surveys before a first TR19 clean
- Sections of duct that can’t be reached
- Kitchens whose menu or hours have changed
- Extracts that may be over the 200 micron mean
School kitchens, at schools like Stanford in the Vale Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost.
Questions to ask before you book
- Whether the quote shows VAT
- What’s included in the scope, part by part
- What hours they’ll be on site
- Whether the quote is based on a survey or pictures
What affects the cost of TR19 inspection
We do not publish a price list, because sites vary so much. What we look at:
- Parking and loading at the site
- The number of sites or systems
- Site requirements such as sign-in and permits
- The times the site is available
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.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or use the quote form.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
What TR19 inspection can’t fix
It’s worth knowing the limits before booking:
- Parts of the duct nobody can reach yet
- Removing the grease, which is a separate clean
- The responsible person’s own fire risk assessment
If you are not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Bow kitchens: local notes
In Bow, food businesses are inspected by environmental health officers from Vale of White Horse council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Bow falls to Oxfordshire 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.
If your kitchen is in a listed or historic building, like the houses around Bow (Longworth House is about 4.3 miles north-east), fitting access panels needs care. Volunteers running a hall kitchen near Church of St Denys, or anywhere in Bow, may not know when the extract was last cleaned, and a grease test settles it.
Bow is about 4 miles east of Faringdon, in Oxfordshire. Sites in Bow get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Our Oxfordshire coverage runs to 443 places, Bow among them. You can also see our page for Oxford, about 14 miles away.

Part by part
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Readings show if the interval is right.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. For a village or hamlet like Bow, tell us about narrow lanes, gates and parking when you book.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, photos and recommendations.
Getting ready for the visit
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

Common questions in Bow
Can the work in Bow be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Bow needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Can you get to a site in Bow?
Yes. Bow is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
Do you carry out TR19 audits for insurers?
Yes, anywhere in the area we cover. Tell us what your insurer has asked for and we’ll set the report out to match.
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 do you measure grease in a kitchen extract?
We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.
How much does TR19 inspection cost in Bow?
We don’t publish prices, because the cost 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.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What else we do in Bow
For landlords and multi-site operators
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
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.
