Ductwork cleaning in Walworth, done properly
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. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers multi-storey ducts, access panels and attenuators, and people most often call us about smells of old cooking grease from the ductwork and a duct clean needed for an insurer.
Kitchens in Walworth, like many across London, can share a building with flats or offices, with the duct running up through shared risers. 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.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

FAQs for Walworth
Who inspects food businesses in Walworth?
Kitchens in Walworth are inspected by Southwark council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can the work in Walworth be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Walworth does not have to lose a day’s trading. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Will I get a report after the ducts are cleaned?
A full system clean comes with a TR19 certificate and a photo report. It includes readings, photos and any unreachable sections.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Is TR19 cleaning required by law?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
Can extra access doors be added to the duct?
Yes, we fit access panels where the duct needs them. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.

Part by part
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, so the responsible person has more reason to keep it clean. The paperwork suits landlords and managing agents.
Horizontal duct runs
Grease settles on the floor of a flat duct run. We scrape out the heavy layer first, then the walls and roof are cleaned too.
Ductwork cleaning in Walworth: the local picture
According to Food Standards Agency records, there are about 252 pubs, bars and clubs and about 49 hotels and B&Bs within roughly a mile and a half of the centre of Walworth. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In Walworth, food businesses are inspected by environmental health officers from Southwark council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in Walworth falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run catering at a healthcare site, such as a hospital like The Walworth Clinic about less than half a mile west, the extract may need cleaning more often than a part-time kitchen. If you run a café or takeaway near Elephant & Castle station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

When to call us in Walworth
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped and it fills faster.
What we are most often called out for:
- Proof of duct cleaning for the insurer
- Grease leaking from duct joints
- High readings at a recent grease test
- Smells of old cooking grease from the ductwork
A hall kitchen that only cooks for events, whether near Lady Margaret Church or elsewhere in Walworth, still needs its extract cleaned, just less often.
What to look for in a quote
- If they look at the system before pricing
- Whether the price is fixed
- When they can work, and whether that’s outside your opening hours
- Whether the whole system is included, or only the parts that are easy to reach
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Get panels fitted where the duct couldn’t be cleaned
- Never cook with a filter missing
- Run the extract fan throughout service
- Have the grease measured if cooking hours go up
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Have access panels fitted where sections cannot be reached. Grease you can reach is grease that gets removed.
Why deal with it now?
Grease left in a duct in Walworth hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. In Walworth, as across London, ductwork often passes through shared risers and other people’s space.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What happens on the day
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a shift or more, depending on the length of the runs and the number of access points. Getting kit into a London building takes planning, so let us know where we can load and park in Walworth.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, pictures and a recommended next clean date complete the job.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
Getting a 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.

What affects the cost of ductwork cleaning
Before we fix a price, we need to know a few things. We check:
- The size of the system
- A single visit or a regular plan
- Travel, parking and unloading
- Site rules, permits and inductions
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
