Ductwork cleaning in Westminster
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. If you have gaps where access panels were never fitted and high readings at a recent grease test, we can put it right, from access panels, bends and junctions and attenuators onwards.
In London, few kitchens can spare a day to close, so work in Westminster is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What we are called out for in Westminster
Risers carry the extract up through the building. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Panels along the riser make proper cleaning possible.
These are the problems we see most often:
- Sections of duct with no access panels
- An insurer asking for TR19 evidence
- A duct nobody has opened in years
- Grease pooling at the foot of the riser
If you cook for passing trade around London Victoria station, the extract can be cleaned between your last and first customer.
Questions to ask before you book
- Whether they recommend a next date
- How areas they cannot reach will be recorded
- What’s included in the scope, part by part
- Whether the work can be done while the site is closed
Why act early in Westminster
TR19® isn’t 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. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

Managing agents and facilities teams in Westminster
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

What we do, step by step
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes from a few hours to more than one visit, depending on duct length and access. In a London area like Westminster, parking, loading and building access are planned before the day of the work.
- 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.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.
Advice
Grease, kitchens and Westminster
Look up Westminster on the FSA’s food hygiene register and you will find about 3,298 cafés, restaurants and staff canteens and about 440 takeaways and sandwich shops within roughly a mile and a half of the centre of Westminster. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. The fire and rescue service for Westminster is London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
School kitchens, at schools like Harris Westminster Sixth Form for example, are usually cleaned in the holidays so no lunches are lost. Volunteers running a hall kitchen near Christ Church, or anywhere in Westminster, may not know when the extract was last cleaned, and a grease test settles it.
Westminster is about 1 mile south-east of City of Westminster, in Greater London. Across the SW1P area, we can carry out ductwork cleaning at your premises. 764 places in Greater London are on our list, from busy centres to quieter spots.
Work in SW1P, W1J and SW1V is surveyed, quoted and booked the same way as anywhere else. We cover sites on Eaton Lane, Wilton Road and Castle Lane and the roads around them.

Westminster: your questions answered
Can you clean school kitchen extracts in Westminster during the holidays?
Yes, and it’s the easiest time to do it. There are about 85 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Westminster. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Can parking be tricky for a job in Westminster?
A loading bay, a visitor permit or off-street space near the site in Westminster makes the visit easier to plan. Much of our London work is done overnight, which helps.
What if part of the duct cannot be reached?
Sections out of reach are written down on the report, as TR19 expects. New panels can be fitted to reach them in future.
Is Westminster in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Westminster.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
What paperwork do you give after a duct clean?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.
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. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When it’s something else
Some problems need a different service or another trade:
- Fire dampers that do not close (they need testing and remedials)
- Parts of the duct with no way in
- A failed fan motor at the end of the duct (a fan repair job)
If you are not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
Where we work
- Bends and junctions
- Attenuators
- Horizontal duct runs
- Multi-storey ducts
- Access panels
- Vertical risers
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Keep your cleaning records together
- Report any grease dripping from duct joints
- Keep the fan on while anything is cooking
- Ask us about extra access panels where sections can’t be reached
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
