Ductwork cleaning in South Hampstead
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. We are often asked to deal with a rancid smell from the extract duct and a duct clean needed for an insurer, on access panels, bends and junctions and multi-storey ducts.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In South Hampstead, 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, with full insurance on top.

What ductwork cleaning looks like in South Hampstead
Food Standards Agency records list about 625 restaurants, cafés and works canteens and about 265 sandwich bars and takeaways within about 1.5 miles of central South Hampstead. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. London jobs normally start after the last service, with loading and roof access agreed with the building first. London Fire Brigade covers South Hampstead. 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.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hospital of St John and St Elizabeth is the nearest hospital to South Hampstead, about 0.7 miles south. Where a hall near Church of All Souls, or anywhere in South Hampstead, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run a café or takeaway near South Hampstead station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
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’re happy to quote for all of it.
How the job changes from site to site
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. We agree a sequence that suits the building, out of hours where possible.
Access panels
Extra panels can be installed where there are gaps, so the next clean reaches more of the system. The survey shows where they’re needed.

FAQs for South Hampstead
Which environmental health team covers South Hampstead?
Kitchens in South Hampstead are inspected by Camden council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you clean school canteen extracts around South Hampstead out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 70 schools and colleges with food registrations within roughly a mile and a half of South Hampstead. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Do I get a certificate for ductwork cleaning?
Readings, photos and, for a full clean, a TR19 certificate. The report says when the next clean is due.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will typically reply within one working day.
Do you have insurance?
Yes. We’re fully insured, and the details are available on request.
How can I tell if my extract ducts are dirty?
Signs include grease dripping from joints, smells and a fan working harder, but measuring is the reliable way to know. A WFTT or DTT reading gives a clear answer.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
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, and that’s where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Leave it or put it right?
TR19® is not 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, including the grease inside the extract ductwork. A busy site in South Hampstead builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or email photos for straight advice and a fixed quote.

How we price ductwork cleaning
Every site gets its own quote. These are the things that affect it:
- The condition we find in the survey
- Parking and loading at the site
- How easy every part is to reach
- The scale of the work
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
To get a fixed quote, phone us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Honest limits
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Leaking duct joints that need repair
- A failed fan motor at the end of the duct (a fan repair job)
- Ductwork that was poorly designed
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly.
What we work on in South Hampstead
- Horizontal duct runs
- Attenuators
- Bends and junctions
- Access panels
- Vertical risers
- Multi-storey ducts
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes a shift or more, depending on the length of the runs and the number of access points. Before any visit in South Hampstead, we agree where the van can stop and how equipment reaches the system.
- 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.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
