TR19 inspection in Radlett, done properly
After a clean, post-clean verification checks the result, with new readings and pictures of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. If you have systems cleaned on a calendar with no measurements and systems that need surveying before cleaning, we can help, from deposit thickness tests, insurer audits and post-clean checks onwards.
Around a smaller place like Radlett, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Because the survey comes first, a visit to Radlett can normally be finished without a second trip.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Before we arrive
- Clear loose items from the work area
- Find the previous report, if there is one
- Let us know when the site is closed or quiet

Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Have the latest report ready for insurance renewals
- Diary the next grease test and clean
- Store grease readings where your insurer can see them
- Mention new equipment or longer hours at the next test
After the inspection, we send a report showing each reading, its location and photos. Keep it with your fire safety and TR19 records.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.

What else we do in Radlett
Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Common questions in Radlett
Who is the fire and rescue service for Radlett?
Radlett 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.
Do you do school kitchen extract cleaning in Radlett in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Radlett, it pays to plan holiday dates ahead. Just call 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Can you verify a clean after it’s been done?
After a clean, we take new readings and pictures to show how the system was left. It can follow our own cleans or another contractor’s.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Do you work out of hours?
Yes. Tell us your opening hours when you ask for a quote and we’ll book around them.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Why survey before a clean?
We survey, measure and photograph the system first. We can work from photos and details, or visit, as suits the job.
Leave it or put it right?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. Booking ahead lets us plan the trip to Radlett at a time that suits you.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Part by part
Canopy and plenum
We look over the canopy, inside and out, with readings where grease collects.
Vertical risers
Access to risers is often limited. The survey shows exactly what access there is.
What we’re called out for in Radlett
Grease is fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Measuring it is the first step to keeping it under control.
It’s time to book a visit if you see:
- Insurance renewals needing proof of TR19 cleaning
- Post-clean verification after another contractor’s clean
- Surveys needed before quoting a full clean
- Parts of the system left out of past cleans
A hospital like Shenley Hospital, about 1.4 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
