Ductwork cleaning for kitchens and businesses in Radlett
Many ducts were installed with too few access doors. Where a section can’t be reached, TR19 expects it to be recorded on the report, and we can fit new access panels so it’s cleaned next time. It’s better to know than to assume. If you’re dealing with an insurer asking for TR19 evidence and a rancid smell from the extract duct, we can put it right, from vertical risers, multi-storey ducts and access panels onwards.
For a smaller kitchen near Radlett, 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.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Common problems we fix in Radlett
Grease filters that don’t seal let fat straight through. More grease reaches the ductwork than it should and it fills faster.
These are the problems we see most often:
- Sections of duct with no access panels
- A duct nobody has opened in years
- Fat dripping from the ductwork
- Heavy grease at the base of a riser
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Shenley Hospital is the nearest hospital to Radlett, about 1.4 miles north-east.

FAQs for Radlett
Is Radlett within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Radlett included. Photos of the system and directions to the site help us plan the visit.
Can you come to Radlett after we close?
Yes, out-of-hours work is a big part of what we do. The work in Radlett can fit around your hours. Just call 0345 646 2711 or email us with your opening times and we’ll plan around them.
How do you clean inside the ductwork?
We survey the route, test the grease, then open the access panels. We clean the runs and risers section by section, and test again when we’re done.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If photos aren’t enough, we’ll survey first.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Will I get a report after the ducts are cleaned?
Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Keep grease filters clean and fitted whenever you cook
- Book the next clean before the recommended date
- Leave a way through to the access panels
- Flag drips from the duct straight away
The report names every part of the duct that couldn’t be reached and why. We can fit access panels so those sections are cleaned next time.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. Testing will show whether any section has reached 500 microns.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Why it’s worth doing now in Radlett

Booking now means the visit to Radlett is planned around you, not forced by a breakdown.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What the work involves, part by part
Vertical risers
Cleaning a riser needs access along its height. Where it cannot be reached safely, the report says so.
Attenuators and discharge
Some systems have attenuators to reduce noise, and their linings can soak up grease. We clean what can be reached and note anything that cannot.
Ductwork cleaning in Radlett: the local picture
According to Food Standards Agency records, there are about 6 bars, pubs and nightclubs within roughly a mile and a half of the centre of Radlett. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Radlett is covered by Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Radlett get their food hygiene inspections from Hertsmere council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
If you cook for passing trade around Radlett station, the extract can be cleaned between your last and first customer. Bursars and site managers at schools such as St John's Church of England Infant and Nursery School tend to book extract cleaning for when the kitchen is empty.
