Ductwork cleaning for kitchens and businesses in North Finchley
Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. An honest report beats a guess. If you’re dealing with thick deposits at the bottom of a vertical duct and duct runs that can’t be reached, we can help, from vertical risers, multi-storey ducts and attenuators onwards.
London kitchens tend to trade late and open early, so work in North Finchley is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Grease, kitchens and North Finchley
The FSA’s data shows about 32 bars, pubs and nightclubs registered within about 1.5 miles of central North Finchley. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in North Finchley are the job of Barnet council’s environmental health team. 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. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Heath Hall is about 2.9 miles south), access may need planning. Term dates shape school work: for a school like Sacks Morasha Jewish Primary School, an extract clean fits neatly into a half-term or summer break.

Common problems we fix in North Finchley
A greasy duct is a fire path, in North Finchley as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Look out for any of the following:
- Sections of duct with no access panels
- Readings above 200 microns from a grease thickness test
- Thick deposits at the bottom of a vertical duct
- Stale grease odours from the duct
A hall kitchen that only cooks for events, whether near St. Barnabas Church or elsewhere in North Finchley, still needs its extract cleaned, just less often.
Before you book anyone
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
- If the quote is a fixed price or an estimate
- How VAT is shown on the quote
Between visits
So the system stays in good health:
- Flag drips from the duct right away
- Run the extract fan throughout service
- Make sure filters are seated properly
- File each certificate and photo report in the maintenance log
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the photos make the duct’s condition easy to see.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
Common questions in North Finchley
Do you work overnight in North Finchley?
Yes, nights and weekends are routine for us. It means the site in North Finchley keeps running as normal. When you call 0345 646 2711 or email us, mention when the site is quiet.
What do you need to know about parking in North Finchley?
Tell us where a van can stop near your site in North Finchley, and about any building rules on loading. Working overnight, as we often do in London, usually makes it simpler.
Do I get a certificate for ductwork cleaning?
A photo report, with readings and before and after pictures, plus a TR19 certificate for a full system clean. It also gives a recommended next clean date.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
How is kitchen extract ductwork cleaned?
After a survey and grease readings, the duct is opened up through its access panels. We clean the runs and risers section by section, and test again when we are done.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Will we have to shut during the visit?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
How the visit 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 shift or more, depending on the length of the runs and the number of access points. Getting kit into a London building takes planning, so let us know where we can load and park in North Finchley.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What else we do in North Finchley
Landlords, agents and facilities managers
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 ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What affects the cost of ductwork cleaning
Every site gets its own quote. This is what makes a difference:
- How easy every part is to reach
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
When you contact us, it’s useful to have:
- Wide photos of the system and the area around it
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
Photos are the quickest way to a quote: 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.
Why act early in North Finchley
A dirty duct is something insurers ask about. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. In North Finchley, a planned overnight visit is much easier than closing unexpectedly.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or send details by email, and we will explain what it covers.
