About our ductwork cleaning in High Barnet
Not sure when the ductwork was last cleaned? Tell us about the system when you ring 0345 646 2711 or use the quote form, and we will give you a fixed quote for ductwork cleaning, normally within one working day. The work covers bends and junctions, access panels and vertical risers, and common reasons people get in touch are a grease test showing the duct is overdue and ductwork that has never been cleaned.
Kitchens in High Barnet, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. 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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Looking after it afterwards
After the visit, a few habits help the work last:
- Ask us about extra access panels where sections cannot be reached
- Keep grease filters clean and fitted whenever you cook
- Ask for a grease thickness test if the kitchen gets busier
- Run the extract fan throughout service
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
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 can’t fix
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Ductwork that was poorly designed
- Parts of the duct with no way in
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly before you book.
Parts of the system we cover
- Vertical risers
- Multi-storey ducts
- Horizontal duct runs
- Attenuators
- Bends and junctions
- Access panels

Signs you need ductwork cleaning in High Barnet
A greasy duct is a fire path, in High Barnet as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Keep an eye out for these warning signs:
- An insurer asking for TR19 evidence
- Stale grease odours from the duct
- High readings at a recent grease test
- Duct runs with no cleaning record
Historic houses near High Barnet, such as Wyllyotts Manor about 2.9 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What your quote should include
- Whether inaccessible sections are listed on the report
- Which accreditations they hold, and whether you can check them
- If the quote is a fixed price or an estimate
- Whether they recommend a next date
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a few hours for a short run, longer for long runs and tall risers. A name and number for whoever controls access to the building in High Barnet saves time on the night.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Before we arrive
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading

Advice
What affects the cost of ductwork cleaning
There’s no set price list, because sites vary so much. What we look at:
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
- Working hours and out-of-hours timing
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 play a part.
Helping us quote
When you call or email, these details help:
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Why it’s worth doing now in High Barnet
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean right away. Leaving the duct makes those limits harder to keep to. Choosing the date yourself beats having a fault choose it for you.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

High Barnet kitchens: local notes
Food Standards Agency records include about 22 pubs and bars in High Barnet and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. London jobs typically start after the last service, with loading and roof access agreed with the building first. Environmental health officers from Barnet council inspect food businesses in High Barnet. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Where a hall near Christ Church, or anywhere in High Barnet, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you look after a school kitchen, at a school such as Foulds School or anywhere near High Barnet, the holidays are the usual time for a TR19® clean.
