About our ductwork cleaning in Lower Holloway
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers bends and junctions, vertical risers and horizontal duct runs, and common reasons people get in touch are a duct nobody has opened in years and a grease test showing the duct is overdue.
In a London area like Lower Holloway, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep the fan on while anything is cooking
- File each certificate and photo report in the maintenance log
- Get panels fitted where the duct couldn’t be cleaned
- Have the grease measured if cooking hours go up
Grease readings are taken again at the same set points, giving you before and after readings. Before and after pictures sit next to the numbers.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Lower Holloway questions
What do you need to know about parking in Lower Holloway?
A loading bay, a visitor permit or off-street space near the site in Lower Holloway makes the visit easier to plan. Much of our London work is done overnight, which helps.
Which fire service covers Lower Holloway?
Fire safety enforcement in Lower Holloway 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.
How much does ductwork cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
How is kitchen extract ductwork cleaned?
We open each access panel and clean the section it reaches. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Is a quote from photos possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What we are called out for in Lower Holloway
Wherever the kitchen is, in Lower Holloway or elsewhere, the duct fills in the same way: daily cooking hours, the menu and the state of the filters. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.
Look out for these warning signs:
- Thick deposits at the bottom of a vertical duct
- Grease leaking from duct joints
- A grease test showing the duct is overdue
- Thick crusts of old grease along the duct
If you run a church or community hall kitchen, near St David or elsewhere in Lower Holloway, its extract still collects grease from every lunch and event.
What your quote should include
- How they set the interval to the next visit
- Whether the figure could change on the day
- Whether the quote is based on a survey or photos
- Whether the whole system is included, or only the parts that are easy to reach
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. On site, it takes from a few hours to more than one visit, depending on duct length and access. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Lower Holloway.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
Before we arrive
- Clear the space around the work
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in

Part by part
Access panels
Panels have to seal properly once they’re closed, so grease and air stay inside the duct. We’ll tell you if any panel needs replacing.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. We clean it back by hand and with degreaser, and readings are taken there before and after.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A worn-out fan that needs replacing
- Parts of the duct with no way in
- A damper stuck open in the duct
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer.

What affects the quote in Lower Holloway
We don’t publish a price list, because sites vary so much. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Parking and loading at the site
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Wide pictures of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What ductwork cleaning looks like in Lower Holloway
According to Food Standards Agency records, there are about 183 pubs and bars and about 47 hotels, B&Bs and guest houses across Lower Holloway and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Environmental health officers from Islington council inspect food businesses in Lower Holloway. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. London jobs typically start after the last service, with loading and roof access agreed with the building first.
Commuter trade near Caledonian Road & Barnsbury station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Bursars and site managers at schools such as Sacred Heart Catholic Primary School tend to book extract cleaning for when the kitchen is empty.
