Ductwork cleaning in Cobham, Surrey
We cover Cobham for 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 pictures as standard.
- Fat dripping from the ductwork
- A duct nobody has opened in years
- Thick deposits at the bottom of a vertical duct
How the job changes from site to site
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, which makes keeping it clean all the more important. The paperwork suits landlords and managing agents.
About our ductwork cleaning in Cobham
We’ve been trading since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers attenuators, access panels and horizontal duct runs, and people most often call us about thick deposits at the bottom of a vertical duct and gaps where access panels were never fitted.
Around a smaller place like Cobham, 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 paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Cobham: your questions answered
Can you get to a site in Cobham?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can school kitchens in Cobham be cleaned in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 8 schools and colleges with food registrations within roughly a mile and a half of Cobham. You can call 0345 646 2711, or send details by email with the dates the site is empty.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
What’s the cleaning interval for extract ductwork?
At least as often as BESA guidance sets for your cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Do I get a certificate for ductwork cleaning?
Readings, photos and, for a full clean, a TR19 certificate. The report says when the next clean is due.
How much does ductwork cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes from a few hours to more than one visit, depending on duct length and access. In a place like Cobham, we fit the visit around your hours.
- We trace the duct and find every way in.
- 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 pictures repeated, and unreachable sections recorded.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
- Tell us where we can park and unload
Ask for a quote
To get a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will usually have a quote within one working day.

Signs you need ductwork cleaning in Cobham
Wherever the kitchen is, in Cobham or elsewhere, the duct fills in the same way: daily cooking hours, the menu and the state of the filters. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Clients usually contact us when they notice something like this:
- Sections of duct with no access panels
- Fat dripping from the ductwork
- Thick deposits at the bottom of a vertical duct
- Hardened, baked-on grease in long horizontal runs
Church and community hall kitchens, near Church of St Andrew or anywhere around Cobham, are easy to forget, but their extracts collect grease like any other.

Ductwork cleaning around Cobham
Food Standards Agency records list about 21 restaurants, cafés and works canteens and about 6 takeaways in Cobham and the streets around it, up to about 1.5 miles out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Cobham sits within the area of Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Elmbridge council that sends environmental health officers to food businesses in Cobham. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand.
For schools such as St Andrew's CofE Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. A hospital like No. 2 New Zealand General Hospital, about 3.9 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Cobham is about 6 miles west of Epsom, in Surrey.

Why deal with it now?
Grease left in a duct in Cobham hardens over time. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Booking now means the visit to Cobham is planned around you, not forced by a breakdown.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Between visits
How long the results last depends on use and care. We suggest:
- Check readings when the menu changes
- Book the next clean before the recommended date
- Do not switch the extract off early
- Keep grease filters clean and fitted whenever you cook
The report names every part of the duct that couldn’t be reached and why. You can then decide whether to have access panels fitted.
Extra access panels mean more of the duct gets cleaned each time. It doesn’t stop grease forming, but it stops it building unseen.
