Why it’s worth doing now in Barnet
An inspection-led approach avoids cleaning ducts that don’t need it. Putting the inspection off just means you do not know where you stand. It’s better booked as a planned job in Barnet than handled as an emergency.
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.

Ventilation duct cleaning in Barnet
When the work is finished, you get a TR19® certificate and before and after pictures. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. If you’re dealing with construction dust left in ducts after a refit and duct runs that can’t be reached for cleaning, we can put it right, from grilles and diffusers, general extract ductwork and toilet extract systems onwards.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Barnet.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Managing agents and facilities teams in Barnet
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
What we are called out for in Barnet
It matters for the people inside: dusty ducts can blow debris back into rooms, restrict airflow and make fans work harder. Where people are vulnerable, as in healthcare and care settings, the stakes are higher.
Look out for any of the following:
- Ductwork with too few access panels to clean
- Dusty supply ductwork that hasn’t been cleaned in years
- Stuffy rooms and stale air
- Damp or stale smells from grilles
If you manage shops or offices close to New Barnet station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Barnet questions
Can parking be tricky for a job in Barnet?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you do school ventilation cleaning in Barnet in the summer holidays?
Yes. The holidays are the usual time for school work. With about 36 schools and colleges on the FSA’s register within roughly a mile and a half of Barnet, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Is a quote from photos possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What does TR19 Air cover?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, rather than kitchen extract. It’s risk-based and led by inspection, and kitchen extract falls under TR19® Grease.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How much does ventilation duct cleaning cost in Barnet?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
Can you clean ventilation out of hours?
Yes, where the building needs it. Tell us when the system can be switched off and we’ll plan to that.
Part by part
Extract ductwork
Extract ducts take air out of toilets, washrooms and general areas. They collect dust, lint and fibres and restrict the flow over time.
Offices and retail
Shared systems in multi-let buildings need access to several areas. We plan access with the managing agent.
Fixed quotes for ventilation duct cleaning in Barnet
Some jobs are bigger than they look, and some smaller. The main factors:
- A single visit or a regular plan
- Working hours and out-of-hours timing
- How easy every part is to reach
- Travel, parking and unloading
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
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 photos, get a survey first. Either way, the quote is fixed before any work is booked.
What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Most London sites cannot stop for the day, so work in Barnet is usually done overnight, early in the morning or at weekends.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
Getting a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
