TR19 inspection in Astwick, done properly
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. The work covers post-clean checks, deposit thickness tests and wet film thickness tests, and the jobs we see most are systems cleaned on a calendar with no measurements and an insurer’s request for a TR19 audit.
In a village or hamlet like Astwick, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
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. It shows what was done and what, if anything, couldn’t be reached.

Staff cleaning versus specialist work
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, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What TR19 inspection cannot fix
It’s worth knowing the limits before booking:
- Sections with no access, until panels are fitted
- The grease itself, which needs a full or spot clean
- Installation problems, which fall under design guidance such as DW172
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.

FAQs for Astwick
Can a school canteen extract in Astwick be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Astwick, it pays to plan holiday dates ahead. Just call us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Do you work overnight in Astwick?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Why survey before a clean?
It’s a look at the whole extract before it’s cleaned, with readings and photos. We can work from photos and details, or visit, as suits the job.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
How often should grease be tested?
Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What do the grease readings need to be?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.

What TR19 inspection looks like in Astwick
The FSA’s food hygiene register shows about 4 restaurants, cafés and canteens and about 4 takeaways and sandwich shops across Astwick and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Astwick is covered by Hertfordshire 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. Kitchens in Astwick get their food hygiene inspections from Central Bedfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
If your kitchen is in a listed or historic building, like the houses around Astwick (Hinxworth Place is about 1.7 miles east), fitting access panels needs care. School kitchens, at schools like St Mary's CofE Academy Stotfold for example, are normally cleaned in the holidays so no lunches are lost.

How the job changes from site to site
Horizontal duct runs
If a run has no access panel, we note it so it can be fixed before the clean.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.
What happens on the day
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Visits to a village like Astwick are booked in advance, at a time that suits whoever runs the site.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.

- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Signs you need TR19 inspection in Astwick
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Signs it’s time to call us include:
- Parts of the system left out of past cleans
- Kitchens taken over with no cleaning records
- Ductwork where grease may be over the TR19 limits
- Systems that need surveying before cleaning
Church and community hall kitchens, near Church of Saint Guthlac or anywhere around Astwick, are easy to forget, but their extracts collect grease like any other.
Questions to ask before you book
- Whether the price is fixed
- Proof of accreditation you can verify
- Whether they recommend a next date
- Whether a written report and photos are included
Looking after it afterwards
To keep the system working properly between visits:
- Keep the route to access panels clear
- Tell us if menus or opening hours change
- Report grease dripping from the canopy
- Wipe the canopy surfaces regularly
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
What happens if it’s left?
Without readings, you are guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. Planning a trip to Astwick ahead is easier for everyone than a rushed one.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
