Ductwork cleaning in Deptford
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Cleaning the duct takes that fuel away. Typical jobs include grease seeping out of the duct seams and a duct clean needed for an insurer, across horizontal duct runs, bends and junctions and attenuators.
Kitchens in Deptford, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Do you need ductwork cleaning in Deptford?
Ducts in Deptford gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Signs it’s time to call us include:
- An insurer asking for TR19 evidence
- Duct runs with no cleaning record
- Heavy grease at the base of a riser
- High readings at a recent grease test
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Deptford is Miller General Hospital, about within half a mile south-east.
Questions to ask before you book
- If they look at the system before pricing
- When they can work, and whether that’s outside your opening hours
- Proof of accreditation you can verify
- Whether the whole system is included, or only the parts that are easy to reach
Why it’s worth doing now in Deptford
Grease left in a duct in Deptford hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
Why book with us
- CHAS, SafeContractor and ISO 9001
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- A single point of contact for sites across the South East and London
- A written report with photos after each visit
Part by part
Vertical risers
Risers are cleaned through panels at different levels. Where it cannot be reached safely, the report says so.
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. They collect grease as the air cools and slows, so each section is cleaned through its access panels.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a few hours to several visits, depending on the length of duct. Before any visit in Deptford, we agree where the van can stop and how equipment reaches the system.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Getting ready for the visit
- Clear the space around the work
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Ductwork cleaning around Deptford
The Food Standards Agency lists about 87 bars, pubs and nightclubs and about 10 hotels and guest houses as registered food businesses across Deptford and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Most London extract cleaning happens at night, after the last service. It’s Lewisham council that sends environmental health officers to food businesses in Deptford. 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.
Commuter trade near Deptford station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. A hall kitchen that only cooks for events, whether near St. Paul's or elsewhere in Deptford, still needs its extract cleaned, just less often.

Common questions in Deptford
Who is the fire and rescue service for Deptford?
Deptford is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you clean school canteen extracts around Deptford out of term?
Yes, holiday work suits schools best. With about 63 schools and colleges on the FSA’s register within roughly a mile and a half of Deptford, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711, or send details by email, and we’ll fit the work in.
When is the ductwork cleaned?
The duct is cleaned out of hours, so evenings, nights and weekends are all possible. Equipment and the extract are switched off while we work.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. If photos are not enough, we’ll survey first.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can you fit access panels in our ductwork?
Yes. We’ll point out where panels are needed, and we can fit them so those sections are cleaned in future.
How can I tell if my extract ducts are dirty?
Drips, smells and weak extraction are clues, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
