TR19 inspection in St Stephens
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you are on. Typical jobs include missing access panels found on survey and sites with gaps in their extract records, on deposit thickness tests, insurer audits and post-clean checks.
For a smaller kitchen near St Stephens, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a couple of hours for a typical kitchen extract system. In a place like St Stephens, we fit the visit around your hours.
- 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.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Before we arrive
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before we start.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Clean or swap grease filters as often as the kitchen needs
- Book the next test on the date in the report
- Flag changes in how much frying the kitchen does
- Store grease readings where your insurer can see them
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. Gaps around filters let grease get past them.
Different parts, different methods
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Readings show if the interval is right.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
St Stephens questions
Can you work in St Stephens outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in St Stephens keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Do you do school kitchen extract cleaning in St Stephens in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 10 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of St Stephens. Send us your term dates when you call 0345 646 2711 or drop us a line, and we will fit the work in.
How long does a TR19 inspection take?
As a guide, it takes around an hour or two per canopy and duct system. System size and access decide the rest.
What do you do with what you remove?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
How often should a kitchen extract be inspected?
That varies with the kitchen’s daily use. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.
Do you cover St Stephens?
Yes. St Stephens is part of the area we cover, within the South East and London area we cover.
What is a WFTT or DTT grease test?
We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.

Other services in St Stephens
Landlords, agents and facilities managers
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 are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What TR19 inspection looks like in St Stephens
The Food Standards Agency lists about 57 bars, pubs and nightclubs and about 4 hotels and B&Bs as registered food businesses across St Stephens and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Hertfordshire Fire and Rescue Service covers St Stephens. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In St Stephens, food businesses are inspected by environmental health officers from St Albans City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
For schools such as Marlborough Science Academy, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to St Stephens is St Albans City Hospital, about 1.3 miles north. For kitchens close to St Albans Abbey station, where the day often starts early and ends late, the extract can be cleaned overnight.
