- Fat dripping from the ductwork
- Grease pooling at the foot of the riser
- High readings at a recent grease test
Common problems we fix in Hanwell
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, which is why ducts go on gathering grease well beyond the filters.
Any of these means the system needs a check-up:
- Duct runs with no cleaning record
- Years of grease along the duct floor
- Readings above 200 microns from a grease thickness test
- A rancid smell from the extract duct
Where a hall near Church of St Mellitus, or anywhere in Hanwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

How we handle ductwork cleaning in Hanwell
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. If you have thick deposits at the bottom of a vertical duct and a duct clean needed for an insurer, we can put it right, from attenuators, vertical risers and bends and junctions onwards.
In London, few kitchens can spare a day to close, so extract cleaning in Hanwell is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

Ductwork cleaning around Hanwell
Look up Hanwell on the FSA’s food hygiene register and you’ll find about 221 cafés, restaurants and staff canteens and about 49 takeaways across Hanwell and its immediate surroundings (about a mile and a half). Where they cook under a canopy, grease does not stop at the filters: it settles along the duct and up the riser. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Environmental health officers from Ealing council inspect food businesses in Hanwell. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens, like those at hospitals such as Ealing Hospital (about under half a mile west), often cook for long hours, which puts them in BESA’s heavier-use bands. For kitchens close to Hanwell station, where the day often starts early and ends late, the extract can be cleaned overnight.

- Faulty fire dampers
- A worn-out fan that needs replacing
- Parts of the duct with no way in

What we do, step by step
We start by comparing what we find with the survey or your pictures. 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. Before any visit in Hanwell, we agree where the van can stop and how equipment reaches the system.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.

Part by part
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
Bends and transitions
Bends, elbows and changes of size are where grease collects most. The air slows and drops its load, so we clean these points carefully.
Hanwell questions
Who enforces fire safety at workplaces in Hanwell?
Fire safety enforcement in Hanwell is handled by 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.
What do you need to know about parking in Hanwell?
Tell us where a van can stop near your site in Hanwell, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
What if part of the duct can’t be reached?
Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.
What shows that the ducts need a clean?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
How long does ductwork cleaning take?
A short duct can be cleaned in a few hours, but long or complex ducts may take several visits. We plan the work around your kitchen.
What happens if it’s left?
Grease left in a duct in Hanwell hardens over time. It bakes into a hard layer that takes far longer to remove, which makes each delayed clean a bigger one. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Between visits
Think of this as the after-treatment advice, in brief:
- File each certificate and photo report in the maintenance log
- Get panels fitted where the duct couldn’t be cleaned
- Don’t switch the extract off early
- Keep grease filters clean and fitted whenever you cook
The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
