Ductwork cleaning in Cowley, Oxfordshire
Ductwork cleaning in Cowley from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.

- Grease pooling at the foot of the riser
Ductwork cleaning in Cowley, done properly
Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. Common call-outs are for duct runs that can’t be reached and hardened, baked-on grease in long horizontal runs, across bends and junctions, vertical risers and horizontal duct runs.
For a smaller kitchen near Cowley, 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. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Signs you need ductwork cleaning in Cowley
A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom, where it can pool. Access along its height is needed to clean it properly.
The symptoms we’re asked about most are:
- Fat dripping from the ductwork
- Gaps where access panels were never fitted
- Readings above 200 microns from a grease thickness test
- Stale grease odours from the duct
Volunteers running a hall kitchen near Church of St Luke, or anywhere in Cowley, may not know when the extract was last cleaned, and a grease test settles it.

Fixed quotes for ductwork cleaning in Cowley
There’s no set price list, because no two systems are the same. What we look at:
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- The size of the system
- Site rules, permits and inductions
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
Asking for a quote
To speed up the quote, send us:
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Keeping the system healthy
To keep the system working properly between visits:
- Report any grease dripping from duct joints
- File each certificate and photo report in the maintenance log
- Run the extract fan throughout service
- Make sure filters are seated properly
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
What ductwork cleaning looks like in Cowley
Food Standards Agency records list about 98 restaurants, cafés and canteens and about 32 takeaways within 1.5 miles or so of the middle of Cowley. The duct above a busy canopy coats itself in grease long before anyone sees it. Cowley sits within the area of Oxfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Oxford City council that sends environmental health officers to food businesses in Cowley. 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.

Why deal with it now?
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. Systems on quieter sites still build up dirt and wear, just more slowly.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

Part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, which is one of the points we test.
Attenuators and discharge
Some systems have attenuators to reduce noise, but they can hold grease in their linings. We clean what can be reached and note anything that can’t.
Your questions about ductwork cleaning in Cowley
Can you get to a site in Cowley?
Yes, we work in villages as well as towns, and Cowley is covered. Photos of the system and directions to the site help us plan the visit.
Can school kitchens in Cowley be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Cowley. Booking early in the term gives the best choice of holiday dates.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
Can you clean ductwork with no access panels?
Without a way in, a section can’t be cleaned properly. We record those sections on the report and can fit access panels.
What’s the cleaning interval for extract ductwork?
It depends mostly on daily cooking hours. Heavy use of 12 to 16 hours a day means at least every 3 months, while lighter use can go longer.
How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a shift or more, depending on the length of the runs and the number of access points, and the area is cleaned down before we leave. In a smaller place like Cowley, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Let us know about parking and loading
- Arrange a key holder or contact on site
- Move anything stored near the system

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
