Ductwork cleaning in Northolt, done properly
Ductwork in Northolt is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Readings are taken again afterwards and photos go into your report. The work covers access panels, bends and junctions and multi-storey ducts, and the jobs we see most are smells of old cooking grease from the ductwork and hardened, baked-on grease in long horizontal runs.
London kitchens tend to trade late and open early, so extract cleaning in Northolt is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Each visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

When to call us in Northolt
A duct with too few access doors can’t be fully cleaned. Sections between panels go uncleaned, sometimes since the system was installed, and grease there keeps thickening unseen.
Most sites get in touch after spotting something like this:
- Smells of old cooking grease from the ductwork
- An insurer asking for TR19 evidence
- Hardened, baked-on grease in long horizontal runs
- A duct nobody has opened in years
Term dates shape school work: for a school like Willow Tree Primary School, an extract clean fits neatly into a half-term or summer break.

Between visits
Good habits slow the build-up between visits. A few tips:
- Store the certificate with the fire risk assessment
- Run the extract fan throughout service
- Consider fitting panels where the report shows gaps
- Keep access panels clear of stored items
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Waste grease and water are taken away.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
What ductwork cleaning cannot fix
A few issues sit outside what this work can do:
- A damper stuck open in the duct
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
If in doubt, call 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers

What affects the quote in Northolt
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Where the site is and how we reach it
- The condition of the system
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
- The postcode and the type of business
To get a fixed quote, phone us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a few hours for a short run, longer for long runs and tall risers. Before any visit in Northolt, 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.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take photos and note any part that couldn’t be reached.
Preparing for the visit
- Tell us where we can park and unload
- Find the previous report, if there is one
- Name a contact who can let us in at the agreed time

Getting a quote doesn’t take long. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
Leave it or put it right?
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, so cleaning the duct is as important as cleaning the hood. London sites work long hours, and the longer a job is left, the bigger it gets.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Your questions about ductwork cleaning in Northolt
Can the work in Northolt be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in Northolt can fit around your hours. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
Who inspects food businesses in Northolt?
That’s Ealing council, whose environmental health officers carry out food hygiene inspections in Northolt. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What should I send you?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
Is TR19 cleaning required by law?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Are you insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. The report shows readings, pictures and any sections we couldn’t reach.
Do you work in Northolt?
Yes. We work in Northolt and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711, or email photos.
Grease, kitchens and Northolt
Food Standards Agency data counts about 159 cafés, restaurants and staff canteens and about 76 sandwich bars and takeaways in and around Northolt, up to about a mile and a half out. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Fire safety in Northolt falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Northolt are the job of Ealing council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Church and community hall kitchens, near St Richard's Church or anywhere around Northolt, are easy to forget, but their extracts collect grease like any other. If you run catering at a healthcare site, such as a hospital like Clementine Churchill Hospital about 2 miles north-east, the extract may need cleaning more often than a part-time kitchen.
