About our ductwork cleaning in Nash
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we cannot is written down, so you know exactly where you stand. The work covers access panels, attenuators and multi-storey ducts, and people most often call us about heavy grease at the base of a riser and fat dripping from the ductwork.
In a London area like Nash, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a few hours for a short run, longer for long runs and tall risers. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Nash.
- We map the duct route and check where the access panels are.
- Set points along the runs are tested for grease.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Arrange a key holder or contact on site
- Move anything stored near the system
- Let us know when the site is closed or quiet
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Before you book, it helps to know what’s not included:
- A damper stuck open in the duct

- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.

How the job changes from site to site
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, so the base is one of our test points.
Attenuators and discharge
Some systems have attenuators to reduce noise, and their linings can soak up grease. They’re cleaned where possible and recorded if not.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Get panels fitted where the duct couldn’t be cleaned
- Keep the fan on while anything is cooking
- Tell us if grease leaks from the ductwork
- Don’t block access panels with shelving or stock
The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
Nash: your questions answered
Which fire and rescue service is responsible for Nash?
That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Does London parking affect a job in Nash?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
How long does ductwork cleaning take?
It takes anything from a few hours to several visits, depending on the length of duct. We will confirm the time when we quote.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
What accreditations do you have?
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 have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
What ductwork cleaning looks like in Nash
There are about 12 restaurants, cafés and canteens and about 13 takeaways and sandwich shops within roughly a mile and a half of the centre of Nash, according to the Food Standards Agency’s register. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Nash is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Nash are the job of Bromley council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a healthcare site, such as a hospital like Princess Royal University Hospital about 1.8 miles east, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near Keston Parish Church, or anywhere in Nash, may not know when the extract was last cleaned, and a grease test settles it.

Around Nash
Typical jobs here are in premises near The Greyhound pub, All Saints Catholic School and Coney Hall Recreation Ground and the streets around them. The closest station to Nash is Hayes (Kent) station, roughly 1.4 miles north of the centre. A little further out are The Mall (3.2 miles north) and Bethlem Museum of the Mind (1.8 miles north). Open spaces near Nash include Hutchinson's Bank and Summer Hill.
Why deal with it now?
TR19® is not law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and grease in the duct is part of that. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.

When to call us in Nash
A greasy duct is a fire path, in Nash 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.
Clients typically contact us after spotting something like this:
- Years of grease along the duct floor
- Duct runs that cannot be reached
- A duct clean needed for an insurer
- Fat dripping from the ductwork
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Down House is about 2.4 miles south-east), access may need planning.
