How we handle ductwork cleaning in Kennington
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We’re 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 are dealing with a grease test showing the duct is overdue and an insurer asking for TR19 evidence, we can put it right.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Kennington, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about ductwork cleaning in Kennington
Who would carry out a food hygiene inspection at a kitchen in Kennington?
Food hygiene inspections in Kennington are carried out by Lambeth council. 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 Kennington be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Kennington can fit around your hours. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
What’s the cleaning interval for extract ductwork?
It follows the same interval as the whole extract, from every 3 months for heavy use to every 12 months for light use. Grease thickness testing shows whether that is often enough.
Can you come out in an emergency?
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.
Do we lose a day’s trading?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Part by part
Horizontal duct runs
The underside of a horizontal duct collects the most grease. We scrape out the heavy layer first, then the walls and roof are cleaned too.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. It’s scraped out and degreased, and test it before and after.
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
When something else is needed
It’s worth knowing the limits before booking:
- A failed fan motor at the end of the duct (a fan repair job)
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- A damper stuck open in the duct
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly before you book.
What we work on in Kennington
- Attenuators
- Access panels
- Vertical risers
- Horizontal duct runs
- Bends and junctions
- Multi-storey ducts
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Check readings when the menu changes
- Diarise the next duct clean
- Keep grease filters clean and fitted whenever you cook
- Flag drips from the duct right away
You will have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
The process
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a few hours for a short run, longer for long runs and tall risers. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Kennington.
- We trace the duct and find every way in.
- We take grease readings along the route.
- 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 pictures repeated, and unreachable sections recorded.
How to prepare
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Move anything stored near the system

- The times we could work without disrupting the site
- Where the site is and what kind of site it is

Ductwork cleaning around Kennington
There are about 1,129 restaurants, cafés and canteens and about 372 takeaways and sandwich shops in and around Kennington, up to about a mile and a half out, according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. Kennington is covered by London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Lambeth council inspect food businesses in Kennington. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
For kitchens close to Vauxhall station, where the day often starts early and ends late, the extract can be cleaned overnight. If you run a church or community hall kitchen, near Calvary Church of God in Christ or elsewhere in Kennington, its extract still collects grease from every lunch and event.
