About our ductwork cleaning in Clapham
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. If you’re dealing with sections of duct with no access panels and high readings at a recent grease test, we can put it right, from horizontal duct runs, multi-storey ducts and attenuators onwards.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Clapham, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When it’s something else
In fairness, there are a few things this work won’t fix:
- An extract fan that has stopped working
- Leaking duct joints that need repair
- A duct that is too small or badly routed for the kitchen (a design issue)
Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly before you book.
What the work covers

Clapham: your questions answered
Do you work at weekends in Clapham?
Yes, nights and weekends are routine for us. The work in Clapham can fit around your hours. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Can parking be tricky for a job in Clapham?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
How is kitchen extract ductwork cleaned?
Through access panels along the duct. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
What shows that the ducts need a clean?
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 fit access panels in our ductwork?
Yes, as part of our fits and repairs work. Panels go where they give the best access to sections that couldn’t be reached, and we will recommend where.
How we price ductwork cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
- A single visit or a regular plan
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- A few general shots of the system
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or email us.
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Kitchen extracts in Clapham
The FSA’s food hygiene register shows about 757 cafés, restaurants and staff canteens and about 239 takeaways and sandwich shops in Clapham 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. In Clapham, food businesses are inspected by environmental health officers from Lambeth council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Most London extract cleaning happens at night, after the last service.
Bursars and site managers at schools such as Clapham Manor Primary School tend to book extract cleaning for when the kitchen is empty. If you run catering at a healthcare site, such as a hospital like Battersea General Hospital about 1.3 miles north-west, the extract may need cleaning more often than a part-time kitchen.
Clapham is about 3 miles north of Streatham, in Greater London. Clapham gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Clapham is one of 764 places in Greater London we cover for ductwork cleaning.
Ductwork cleaning in SW4, SW8 and SW9 follows the same survey, fixed quote and written report as everywhere else we cover. That includes premises on Grafton Square, Clapham High Street and Houghton Square and the roads around them. Clapham is on the B224 and B303, so it’s easy for us to get to for ductwork cleaning. If your site is just outside Clapham, we cover Stockwell (1 mile east), Little Portugal (1 mile north-east), Clapham Park (1 mile south), South Lambeth (1 mile north-east) and Brixton (1 mile south-east). We also work in nearby towns such as London (3 miles north-east), City of Westminster (3 miles north), Marylebone (4 miles north), Kensington (4 miles north-west), St Pancras (4 miles north) and Shoreditch (5 miles north-east).
Around Clapham
In Clapham, that means kitchens and buildings near Lambeth Academy, Larkhall Park and Trinity Academy, among other places. There’s a railway station in Clapham itself: Clapham High Street station. A little further out are Baynard's Castle (3.5 miles north-east) and Harrods (2.6 miles north-west). For a walk, there’s Battersea Park Lake and Knight's Hill.
Different parts, different methods
Access panels
We can fit new access panels where the duct needs them, so the next clean reaches more of the system. The survey shows where they’re needed.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. We agree a sequence that suits the building, out of hours where possible.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
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.
What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from a few hours to several visits, depending on the length of duct. We fit London jobs around the building rather than the other way round, so a visit in Clapham is typically out of hours.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
- Mention any sign-in, permit or induction we need
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Advice
Signs you need ductwork cleaning in Clapham
Air cools as it moves away from the canopy. Cooling air drops its grease onto the inside of the duct, which is why ducts go on gathering grease well beyond the filters.
The symptoms we’re asked about most are:
- Stale grease odours from the duct
- Grease leaking from duct joints
- Heavy grease at the base of a riser
- An insurer asking for TR19 evidence
Volunteers running a hall kitchen near St Paul's Church, or anywhere in Clapham, may not know when the extract was last cleaned, and a grease test settles it.
