Ductwork Cleaning in North Cheam
Our technicians work in North Cheam on cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Grease leaking from duct joints
- Ductwork that has never been cleaned
- A duct clean needed for an insurer
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Ductwork cleaning in North Cheam, done properly
Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and we can fit new access panels so it’s cleaned next time. An honest report beats a guess. We are often asked to deal with a duct nobody has opened in years and years of grease along the duct floor, on multi-storey ducts, vertical risers and bends and junctions.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in North Cheam, that typically means a longer system to clean and more access panels to plan around.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

When to call us in North Cheam
A greasy duct is a fire path, in North Cheam as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Look out for these warning signs:
- A duct clean needed for an insurer
- Smells of old cooking grease from the ductwork
- Thick crusts of old grease along the duct
- Grease leaking from duct joints
For kitchens close to West Sutton station, where the day often starts early and ends late, the extract can be cleaned overnight.

FAQs for North Cheam
Who carries out food hygiene inspections in North Cheam?
The local authority for North Cheam is Sutton council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you come to North Cheam after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
How much does ductwork cleaning cost in North Cheam?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
How long does ductwork cleaning take?
Allow a few hours for a short run, longer for long runs and tall risers. The survey tells us how long your duct needs.
Is TR19 a legal requirement?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Ductwork cleaning in North Cheam: the local picture
Food Standards Agency records list about 200 restaurants, cafés and works canteens and about 96 sandwich bars and takeaways in North Cheam and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. Kitchens in North Cheam get their food hygiene inspections from Sutton council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Healthcare kitchens, like those at hospitals such as St. Anthony's Hospital (about 0.6 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. School kitchens, at schools like Cheam Park Farm Primary Academy for example, are normally cleaned in the holidays so no lunches are lost.

Different parts, different methods
Access panels
Access panels are the doors that let us into the duct. Where there are none, those sections can’t be cleaned and the report has to say so.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. It’s scraped out and degreased, and readings are taken there before and after.
When it’s something else
In fairness, there are a few things this work won’t fix:
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that don’t close (they need testing and remedials)
- Duct sealed behind fixed ceilings or walls
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly.
Where we work
- Access panels
- Vertical risers
- Attenuators
- Horizontal duct runs
- Multi-storey ducts
- Bends and junctions
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a few hours for a short run, longer for long runs and tall risers. Night and weekend working is normal for us in London, and a site in North Cheam is no exception.
- We trace the duct and find every way in.
- We take grease readings along the route.
- 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.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or send us an email.
Related advice
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Run the extract fan throughout service
- Never cook with a filter missing
- Report any grease dripping from duct joints
- Leave a way through to the access panels
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.
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.
