The duct above a busy canopy coats itself in grease long before anyone sees it. Environmental health officers from East Hertfordshire council inspect food businesses in Thorley Street. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.

In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

About our ductwork cleaning in Thorley Street
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for grease leaking from duct joints and duct runs with no cleaning record, across horizontal duct runs, bends and junctions and attenuators.
In a small place like Thorley Street, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Common questions in Thorley Street
Do you work at weekends in Thorley Street?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Can school kitchens in Thorley Street be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of Thorley Street. Just call us on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can extra access doors be added to the duct?
Yes. We will point out where panels are needed, and we can fit them so those sections are cleaned in future.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do you cover Thorley Street?
Yes. Thorley Street is part of the area we cover, within the South East and London area we cover.
How the job changes from site to site
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, which is one of the points we test.
Attenuators and discharge
The last section of duct before the discharge is often the coolest, which can mean heavier deposits. We include it in the clean and the readings.
What we’re called out for in Thorley Street
Ducts in Thorley Street gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
If you notice any of these, it’s worth a diagnosis:
- Grease leaking from duct joints
- A grease test showing the duct is overdue
- Duct runs that cannot be reached
- Smells of old cooking grease from the ductwork
Bursars and site managers at schools such as Thorley Hill Primary School tend to book extract cleaning for when the kitchen is empty.

What else we do in Thorley Street
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a shift or more, depending on the length of the runs and the number of access points. We agree a date with you, plan the drive to Thorley Street and turn up when the site is quiet.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions

We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, give us a ring on 0345 646 2711 or use the quote form.
Related advice
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Report any grease dripping from duct joints
- Run the extract fan throughout service
- Keep your cleaning records together
- Never cook with a filter missing
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
What happens if it’s left?
A fire in a greasy duct is hard to reach and hard to stop. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. With notice, the visit to Thorley Street can be fitted around your bookings and events.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
