TR19 inspections and grease testing in Brookmans Park, Hertfordshire
TR19 inspection across Brookmans Park and nearby, timed so the site keeps working and finished with a written report and pictures.
- Kitchen extract systems with no recent grease readings
- Parts of the system left out of past cleans
- Uncertainty over how often to clean
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
How we handle TR19 inspection in Brookmans Park
If you’ve taken over a kitchen in Brookmans Park and do not know when the extract was last cleaned, an inspection is the place to start. You get readings, photos and a clear view of what’s needed, before any cleaning is booked. The work covers access surveys, post-clean checks and pre-clean surveys, and the jobs we see most are kitchen extract systems with no recent grease readings and cleaning intervals that may not suit the kitchen.
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. Access, parking and timings are agreed before the day.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

FAQs for Brookmans Park
Who inspects food businesses in Brookmans Park?
Food hygiene inspections in Brookmans Park are carried out by Welwyn Hatfield council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you work overnight in Brookmans Park?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Brookmans Park needn’t be disturbed. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
How often should a kitchen extract be inspected?
It depends on how heavily the kitchen cooks. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
TR19 inspection in Brookmans Park: the local picture
There are about 12 cafés, restaurants and staff canteens within about 1.5 miles of central Brookmans Park, 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. Brookmans Park sits within the area of Hertfordshire 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. Environmental health officers from Welwyn Hatfield council inspect food businesses in Brookmans Park. 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.
School kitchens, at schools like Chancellor's School for example, are usually cleaned in the holidays so no lunches are lost. If you run catering at a healthcare site, such as a hospital like Queen Elizabeth II Hospital about 4.2 miles north, the extract may need cleaning more often than a part-time kitchen.

Aftercare tips
Here’s the after-treatment advice, in brief:
- File every inspection report with your certificates
- Keep to the recommended interval
- Never cook with filters missing
- Keep the route to access panels clear
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can arrange it.
Keep all TR19 records together so the history is easy to show.
How the job changes from site to site
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
Canopy and plenum
Clean-looking filters don’t mean a clean plenum. So we measure behind the filters, not just in front.
How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes around an hour or two per canopy and duct system. Pictures of the system and its access let us plan the work in Brookmans Park before we set off.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions

Why act early in Brookmans Park

Common problems we fix in Brookmans Park
Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
The symptoms we’re asked about most include:
- Ductwork where grease may be over the TR19 limits
- Pre-clean surveys before a first TR19 clean
- Checking the result of a recent clean
- An insurer’s request for a TR19 audit
Volunteers running a hall kitchen near United Reformed Church Brookmans Park, or anywhere in Brookmans Park, may not know when the extract was last cleaned, and a grease test settles it.
