Ductwork cleaning in Harringay, done properly
We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after photos. The work covers access panels, multi-storey ducts and bends and junctions, and the jobs we see most are grease seeping out of the duct seams and gaps where access panels were never fitted.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Harringay, 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, and we’re fully insured.

FAQs for Harringay
Who is the fire and rescue service for Harringay?
That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you do school kitchen extract cleaning in Harringay in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 40 schools and colleges with food registrations within roughly a mile and a half of Harringay. You can ring 0345 646 2711, or send details by email with the dates the site is empty.
When is the ductwork cleaned?
We clean while the kitchen is closed, so evenings, nights and weekends are all possible. The extract and cooking equipment need to be off.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What paperwork do you give after a duct clean?
You get a photo report with before and after photos, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
How often should kitchen ducts be cleaned?
The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
What ductwork cleaning looks like in Harringay
Look up Harringay on the FSA’s food hygiene register and you will find about 442 restaurants, cafés and canteens and about 142 takeaways and sandwich shops within about 1.5 miles of central Harringay. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. London jobs usually start after the last service, with loading and roof access agreed with the building first. Kitchens in Harringay get their food hygiene inspections from Haringey council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
School kitchens, at schools like South Harringay Infant School for example, are typically cleaned in the holidays so no lunches are lost. A kitchen near Harringay Green Lanes station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Where a hall near St Paul's Harringay, or anywhere in Harringay, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Aftercare tips
Results last longer with the right care. We suggest:
- Get panels fitted where the duct couldn’t be cleaned
- Keep access panels clear of stored items
- Run the extract fan throughout service
- Never cook with a filter missing
After the clean, the same points are tested again, giving you before and after readings. Photos of each section go alongside them.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes a few hours for a short run, longer for long runs and tall risers. Expect the work in Harringay to happen after your last customer leaves, not during trading.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand

Advice
What the work involves, part by part
Bends and transitions
Wherever the duct turns or changes size, grease builds up. Slowing air leaves grease behind, so these points get extra attention.
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. Your certificate and report give building managers the record they need.
Why deal with it now?
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, and grease in the duct is part of that. In Harringay, as across London, ductwork often passes through shared risers and other people’s space.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
