Ductwork Cleaning in Hampstead
Ductwork cleaning for businesses, landlords and public buildings in Hampstead. CHAS, SafeContractor and ISO 9001, and fully insured.
- Smells of old cooking grease from the ductwork
- Sections of duct with no access panels
- Ductwork that has never been cleaned
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a few hours for a short run, longer for long runs and tall risers. For a job in Hampstead, tell us about loading bays, permits, lifts and roof access when you book.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, photos and a next clean date.
Getting ready for the visit
- Agree a time when the area can be out of use
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before we start.

Ductwork cleaning in Hampstead, done properly
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after photos. The work covers horizontal duct runs, bends and junctions and vertical risers, and people most often call us about hardened, baked-on grease in long horizontal runs and thick deposits at the bottom of a vertical duct.
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 Hampstead, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What else we do in Hampstead
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Different parts, different methods
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and readings are taken there before and after.
Multi-storey and shared buildings
In a building with several floors, the duct may pass other tenants’ spaces. We plan access with you and the building manager, so the clean is done safely and quietly.
Aftercare tips
After the visit, a few habits help the work last:
- Flag drips from the duct straight away
- Diarise the next duct clean
- Do not block access panels with shelving or stock
- Keep your cleaning records together
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.
Why act early in Hampstead
Grease left in a duct in Hampstead hardens over time. Heat and age turn it into a thick, stubborn crust, which makes each delayed clean a bigger one. Choosing the date yourself beats having a fault choose it for you.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Questions from Hampstead
Who is the fire and rescue service for Hampstead?
Hampstead is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who would carry out a food hygiene inspection at a kitchen in Hampstead?
That’s Camden council, whose environmental health officers carry out food hygiene inspections in Hampstead. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
How often should kitchen ducts be cleaned?
It follows the same interval as the whole extract, from every 3 months for heavy use to every 12 months for light use. Readings tell you if it needs to be more often.
What’s involved in cleaning extract ducts?
We survey the route, test the grease, then open the access panels. We clean the runs and risers section by section, and test again when we’re done.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What ductwork cleaning can’t fix
Some problems need a different service or another trade:
- A worn-out fan that needs replacing
- A duct that’s too small or badly routed for the kitchen (a design issue)
- Fire dampers that don’t close (they need testing and remedials)
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly before you book.
Parts of the system we cover

Common problems we fix in Hampstead
Grease in a duct running from a kitchen in Hampstead is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Common reasons sites call us are:
- A duct clean needed for an insurer
- Duct runs that cannot be reached
- A rancid smell from the extract duct
- Ductwork that has never been cleaned
If you cook for passing trade around Finchley Road & Frognal station, the extract can be cleaned between your last and first customer.

Hampstead kitchens: local notes
The Food Standards Agency lists about 60 pubs and bars and about 23 hotels and guest houses as registered food businesses across Hampstead and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. It’s Camden council that sends environmental health officers to food businesses in Hampstead. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Hampstead is 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.
For schools such as Fitzjohn's Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near St John-at-Hampstead church or elsewhere in Hampstead, its extract still collects grease from every lunch and event.
