Ductwork cleaning in East Barnet
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers access panels, horizontal duct runs and attenuators, and the jobs we see most are grease leaking from duct joints and an insurer asking for TR19 evidence.
London kitchens tend to trade late and open early, so extract cleaning in East Barnet is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Do you need ductwork cleaning in East Barnet?
A duct with too few access doors cannot be fully cleaned. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
What we’re most often called out for:
- Grease pooling at the foot of the riser
- Duct runs that cannot be reached
- Duct runs with no cleaning record
- Stale grease odours from the duct
If you run catering at a healthcare site, such as a hospital like Finchley Memorial Hospital about 2.2 miles south-west, the extract may need cleaning more often than a part-time kitchen.

- What insurance they carry
What we do, step by step
Each visit runs to the same pattern: protect the area, make the system safe, carry out the ductwork cleaning, clear away and hand over the paperwork. On site, the work takes a few hours for a short run, longer for long runs and tall risers. In East Barnet, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading
- Clear the space around the work

Why deal with it now?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Why us?
- Every job surveyed first
- CHAS, SafeContractor and ISO 9001
- Fully insured
- One number for every site across the South East and London

Different parts, different methods
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
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.
Staff cleaning versus specialist work
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’ll take a look and send you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
East Barnet kitchens: local notes
Look up East Barnet on the FSA’s food hygiene register and you will find about 169 restaurants, cafés and canteens and about 71 takeaways across East Barnet and its immediate surroundings (about a mile and a half). Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. East Barnet is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Term dates shape school work: for a school like Church Hill School, an extract clean fits neatly into a half-term or summer break. If you run a church or community hall kitchen, near St Mary the Virgin or elsewhere in East Barnet, its extract still collects grease from every lunch and event.

FAQs for East Barnet
What do you need to know about parking in East Barnet?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Who inspects food businesses in East Barnet?
The local authority for East Barnet is Barnet council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
When is the ductwork cleaned?
Only while we are working, and we work around you. Overnight and weekend work is common, so no service is lost.
How often does extract ductwork need cleaning?
It follows the same interval as the whole extract, ranging from 3-monthly to 12-monthly. Readings tell you if it needs to be more often.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Store the certificate with the fire risk assessment
- Never cook with a filter missing
- Keep the fan on while anything is cooking
- Flag drips from the duct straight away
After the clean, the same points are tested again, so the report shows the before and after figures. Before and after pictures sit next to the numbers.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
