Hertfordshire · TR19 inspections and grease testing
Stevenage TR19 inspection
Looking for TR19 inspection in Stevenage? We survey first, give you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Extracts that have never been grease tested
- Ductwork where grease may be over the TR19 limits
- Missing TR19 certificates or history
Different parts, different methods
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Regular testing shows whether the cleaning interval keeps up.
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
About our TR19 inspection in Stevenage
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. Typical jobs include kitchen extract systems with no recent grease readings and uncertainty over how often to clean, across deposit thickness tests, insurer audits and post-clean checks.
In the busier parts of Stevenage, kitchens are often on the ground floor with flats or offices above, and the extract can climb several storeys before it discharges. Vertical risers like that need access panels in the right places, and anything we cannot reach goes on the report.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
What a clean won’t put right
TR19 inspection can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- The legal duty, which stays with the responsible person
- Removing the grease, which is a separate clean
- Hidden runs that need access panels first
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think.

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Managed buildings in a place the size of Stevenage often have sign-in, permits-to-work and key holders, and the visit is planned around them.
- The visit is arranged for when the kitchen isn’t busy.
- 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.
- You get a report with readings, pictures and recommendations.
Preparing for the visit
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions

Advice
Grease, kitchens and Stevenage
Food Standards Agency records list about 105 cafés, restaurants and staff canteens and about 71 takeaways and sandwich shops within roughly a mile and a half of the centre of Stevenage. For any of them with a canopy, measuring grease is better than guessing when to clean. Kitchens in Stevenage get their food hygiene inspections from Stevenage 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. The fire and rescue service for Stevenage is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run catering at a healthcare site, such as a hospital like Lister Hospital about 1.7 miles north-west, the extract may need cleaning more often than a part-time kitchen. School kitchens, at schools like Saint Vincent de Paul Catholic Primary School for example, are typically cleaned in the holidays so no lunches are lost. Aston Bury, about 2.5 miles south-east, is one of the historic houses near Stevenage; if you run event catering at a venue like that, cleans can be booked between functions.

How we price TR19 inspection
Your quote is based on your site. We consider:
- The condition of the system
- Where the site is and how we reach it
- Whether several sites go on one quote
- A single visit or a regular plan
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
Helping us quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To get a fixed quote, call us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Clean or swap grease filters as often as the kitchen needs
- Diary the next grease test and clean
- Report grease dripping from the canopy
- Have the latest report ready for insurance renewals
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.

What else we do in Stevenage
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Questions from Stevenage
Which fire and rescue service is responsible for Stevenage?
Stevenage is in the area of Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can a school canteen extract in Stevenage be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 39 schools, colleges and universities with registered kitchens within about a mile and a half of Stevenage. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we’ll fit the work in.
Can you work evenings and weekends?
Yes. Tell us your opening hours when you ask for a quote and we will book around them.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
