What happens if it’s left?
Old grease in a duct for a kitchen in Dartmouth Park doesn’t stay soft. It bakes into a hard layer that takes far longer to remove, which makes each delayed clean a bigger one. Choosing the date yourself beats having a fault choose it for you.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

About our ductwork cleaning in Dartmouth Park
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers access panels, multi-storey ducts and attenuators, and common reasons people get in touch are a rancid smell from the extract duct and a duct clean needed for an insurer.
London kitchens tend to trade late and open early, so extract cleaning in Dartmouth Park is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Keeping the system healthy
To keep the system working properly between visits:
- Run the extract fan throughout service
- Ask for a grease thickness test if the kitchen gets busier
- Keep to the interval on the report
- Report any grease dripping from duct joints
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
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.

Dartmouth Park: your questions answered
Who enforces fire safety at workplaces in Dartmouth Park?
London Fire Brigade is the fire and rescue service for Dartmouth Park. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can school kitchens in Dartmouth Park be cleaned in the holidays?
Yes, and it’s the easiest time to do it. With about 50 schools and colleges on the FSA’s register within roughly a mile and a half of Dartmouth Park, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711, or email photos, and we will fit the work in.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Can extra access doors be added to the duct?
Yes, we do. We will point out where panels are needed, and fitting them means future cleans are more complete.
How long will the duct clean take?
Duct length, access and grease levels all affect it. Typically it takes a shift or more, depending on the length of the runs and the number of access points.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or send us an email.
What’s the cleaning interval for extract ductwork?
BESA guidance sets minimum intervals by daily cooking hours: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours for a short run, longer for long runs and tall risers. Night and weekend working is normal for us in London, and a site in Dartmouth Park is no exception.
- We map the duct route and check where the access panels are.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
Getting a quote
Getting a quote does not take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Different parts, different methods
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Access panels
After cleaning, every panel is closed and sealed, so grease and air stay inside the duct. A damaged panel is noted on the report.
Grease, kitchens and Dartmouth Park
Food Standards Agency records list about 636 cafés, restaurants and staff canteens and about 305 sandwich bars and takeaways within roughly a mile and a half of the centre of Dartmouth Park. The duct above a busy canopy coats itself in grease long before anyone sees it. Environmental health officers from Camden council inspect food businesses in Dartmouth Park. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Dartmouth Park is London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run catering at a healthcare site, such as a hospital like Royal Northern Hospital about 0.8 miles east, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like Acland Burghley School, an extract clean fits neatly into a half-term or summer break.

When to call us in Dartmouth Park
Risers carry the extract up through the building. Grease clings to the walls and can run down to the base, where it can pool. Access along its height is needed to clean it properly.
Keep an eye out for these warning signs:
- Duct runs with no cleaning record
- High readings at a recent grease test
- A rancid smell from the extract duct
- Grease leaking from duct joints
Volunteers running a hall kitchen near Church of St Mary Brookfield, or anywhere in Dartmouth Park, may not know when the extract was last cleaned, and a grease test settles it.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
