Ductwork cleaning for kitchens and businesses in Hanworth
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. The work covers bends and junctions, horizontal duct runs and access panels, and people most often call us about duct runs that can’t be reached and a rancid smell from the extract duct.
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 Hanworth, that normally means a longer system to clean and more access panels to plan around.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

The process
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. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from a few hours to more than one visit, depending on duct length and access. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Hanworth.
- We map the duct route and check where the access panels are.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
How to prepare
- Clear loose items from the work area
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions

FAQs for Hanworth
Can you clean school kitchen extracts in Hanworth during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Hanworth. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.
Does London parking affect a job in Hanworth?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
What shows that the ducts need a clean?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. A WFTT or DTT reading gives a clear answer.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How do you clean inside the ductwork?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
What happens if there aren’t enough 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.
How we price ductwork cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Travel, parking and unloading
- Site requirements such as sign-in and permits
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
What we need to know
Photos let us diagnose from a distance. Try to include:
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
- When the site is open and when it’s quiet
- The site address and the type of premises
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, give us a ring on 0345 646 2711, or email photos.
Signs you need ductwork cleaning in Hanworth
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, so duct runs keep collecting grease long after the canopy.
The symptoms we’re asked about most are:
- High readings at a recent grease test
- An insurer asking for TR19 evidence
- Fat dripping from the ductwork
- Grease pooling at the foot of the riser
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Teddington Memorial Hospital is the nearest hospital to Hanworth, about 1.8 miles east.
What your quote should include

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
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 can diagnose it and quote.
Different parts, different methods
Access panels
After cleaning, every panel is closed and sealed, so grease and air stay inside the duct. A damaged panel is noted on the report.
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. Grease drops out of the slowing air along them, and we clean them section by section through access panels.
Kitchen extracts in Hanworth
Food Standards Agency data counts about 57 restaurants, cafés and works canteens and about 25 takeaways across Hanworth and its immediate surroundings (about a mile and a half). Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Hanworth is covered by London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
A hall kitchen that only cooks for events, whether near St Richard's Church or elsewhere in Hanworth, still needs its extract cleaned, just less often. School kitchens, at schools like Buckingham Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Do not switch the extract off early
- Never cook with a filter missing
- Ask us about extra access panels where sections cannot be reached
- Have the grease measured if cooking hours go up
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.
Why act early in Hanworth
Grease left in a duct in Hanworth hardens over time. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. It’s better booked as a planned job in Hanworth than handled as an emergency.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
