Ductwork cleaning in Friern Barnet
We’ve been trading since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. If you’re dealing with sections of duct with no access panels and grease pooling at the foot of the riser, we can put it right, from attenuators, access panels and bends and junctions onwards.
London kitchens tend to trade late and open early, so work in Friern Barnet is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
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.
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, and that takes from a few hours to more than one visit, depending on duct length and access. Most London sites can’t stop for the day, so work in Friern Barnet is normally done overnight, early in the morning or at weekends.
- We map the duct route and check where the access panels are.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.

Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
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. Where responsibility is shared, records matter even more.
What affects the cost of ductwork cleaning
We quote each job individually. This is what makes a difference:
- Whether several sites go on one quote
- The condition we find in the survey
- How big the system is
- One-off work versus a regular cycle
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- Where the site is and what kind of site it is
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then ring 0345 646 2711, or email photos.
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Report any grease dripping from duct joints
- Never cook with a filter missing
- Keep access panels clear of stored items
- Ask us about extra access panels where sections cannot be reached
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.
Questions from Friern Barnet
Do you work at weekends in Friern Barnet?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Friern Barnet needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Can parking be tricky for a job in Friern Barnet?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we will book into it.
Do we need to close while you work?
Not typically. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.
Is TR19 cleaning required by law?
No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How often does extract ductwork need cleaning?
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 types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Do you cover Friern Barnet?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Friern Barnet.

When something else is needed
We will not sell you work that does not address the problem, so here are the limits:
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- A failed fan motor at the end of the duct (a fan repair job)
- Leaking duct joints that need repair
If you are not sure, just phone us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

Ductwork cleaning around Friern Barnet
The FSA’s data shows about 40 pubs and bars and about 3 hotels, B&Bs and guest houses registered across Friern Barnet and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. London Fire Brigade covers Friern Barnet. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
A kitchen near New Southgate station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Bursars and site managers at schools such as Holly Park Primary School tend to book extract cleaning for when the kitchen is empty. If you run catering at a healthcare site, such as a hospital like Coppetts Wood Hospital about 0.7 miles south, the extract may need cleaning more often than a part-time kitchen.

Why deal with it now?
A dirty duct is something insurers ask about. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. Your certificate and photo report show the ducts were cleaned. In Friern Barnet, as across London, ductwork often passes through shared risers and other people’s space.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.
