About our ductwork cleaning in City of Westminster
We have been trading since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers vertical risers, attenuators and access panels, and the jobs we see most are thick deposits at the bottom of a vertical duct and smells of old cooking grease from the ductwork.
In London, few kitchens can spare a day to close, so work in City of Westminster is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Ductwork cleaning in City of Westminster: the local picture
The FSA’s food hygiene register includes about 229 bars, pubs and nightclubs and about 280 hotels, B&Bs and guest houses in and around City of Westminster, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. City of Westminster is covered by London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Most London extract cleaning happens at night, after the last service.
A hospital like Fortius Clinic, about within half a mile north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you cook for passing trade around Bond Street station, the extract can be cleaned between your last and first customer.

Why act early in City of Westminster
Dealing with the ductwork in City of Westminster now beats dealing with it after a problem. The work takes a few hours for a short run, longer for long runs and tall risers, and we work evenings, overnight and weekends. Every month a London system goes without attention adds to what has to be done later.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Common problems we fix in City of Westminster
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Clients normally contact us when they notice something like this:
- A grease test showing the duct is overdue
- Thick deposits at the bottom of a vertical duct
- Years of grease along the duct floor
- Fat dripping from the ductwork
If you run a church or community hall kitchen, near St Mark's or elsewhere in City of Westminster, its extract still collects grease from every lunch and event.

Different parts, different methods
Horizontal duct runs
A long flat run can’t be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
Vertical risers
Risers often pass through floors and walls, so fire dampers may be fitted where it crosses them. Damper testing is a separate service.

FAQs for City of Westminster
Can school kitchens in City of Westminster be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 78 schools and colleges with food registrations within roughly a mile and a half of City of Westminster. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
Who would carry out a food hygiene inspection at a kitchen in City of Westminster?
Kitchens in City of Westminster are inspected by Westminster council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can extra access doors be added to the duct?
Yes, as part of our fits and repairs work. We place them where they help most, and we will recommend where.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
How can I tell if my extract ducts are dirty?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Can you clean ductwork with no access panels?
Sections out of reach are written down on the report, as TR19 expects. New panels can be fitted to reach them in future.
Can you quote from photos?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
The process
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours to more than one visit, depending on duct length and access. Loading bays, visitor permits and roof access are the first things we ask about for a site in City of Westminster.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and photos go into the report, with any unreachable section listed.
Before we arrive
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
