How we handle TR19 inspection in Tonwell
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Without it, a claim can be refused or reduced. Our TR19 audits give sites in Tonwell and across Hertfordshire a clear record of the system’s condition. The work covers deposit thickness tests, access surveys and post-clean checks, and people most often call us about extracts that may be over the 200 micron mean and pre-clean surveys before a first TR19 clean.
In a small place like Tonwell, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How we price TR19 inspection
There’s no set price list, because sites vary so much. The quote depends on:
- How big the system is
- Parking and loading at the site
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.
What we need to know
To help us quote quickly, please include:
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
When it’s something else
Some problems need a different service or another trade:
- Design faults in the extract system
- Fire safety duties beyond the extract system
- A faulty or failing extract fan
If you’re not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Post-clean checks
- Access surveys
- Insurer audits
- Pre-clean surveys
- Deposit thickness tests
- Wet film thickness tests
Aftercare tips
Once we have finished, these simple steps help:
- Keep access panels clear and unpainted
- Keep to the recommended interval
- Flag changes in how much frying the kitchen does
- File every inspection report with your certificates
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
Keep certificates, reports and readings in one place so you can produce them quickly.
Why act early in Tonwell
If there’s a fire or a claim, your insurer may ask for TR19 records. Without them, a claim can be reduced or refused. Getting an inspection done now starts that paper trail. Equipment tucked in a roof space or outbuilding near Tonwell rarely gets looked at unless someone books it.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
Why book with us
- Photo reports with every job
- Survey first, then a fixed quote

What TR19 inspection looks like in Tonwell
Food Standards Agency data counts about 4 restaurants, cafés and works canteens in Tonwell and the streets around it, up to about 1.5 miles out. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Hertfordshire Fire and Rescue Service covers Tonwell. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from East Hertfordshire council inspect food businesses in Tonwell. 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.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 4.6 miles north-west), access may need planning. A hospital like Hertford County Hospital, about 3 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. For schools such as Tonwell St Mary's Church of England Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

FAQs for Tonwell
Do you work at weekends in Tonwell?
Yes, evening, overnight and weekend work is normal for us. That way a site in Tonwell doesn’t have to lose a day’s trading. Just phone us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Which fire and rescue service is responsible for Tonwell?
Tonwell is in the area of Hertfordshire Fire and Rescue Service. 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.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
Can you verify a clean after it’s been done?
It’s an inspection after cleaning, to show what state the system was left in, whoever did the clean.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do we have to follow TR19 by law?
No. TR19® isn’t law; it’s BESA’s specification. 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.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
How the visit works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a morning or less for one kitchen, more where there are several systems. If you can send photos, we can arrive in Tonwell knowing what to expect.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
How to prepare
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
