How we handle ventilation duct cleaning in Hendon
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, alongside filter changes and AHU maintenance. If you’re dealing with blocked general extract ductwork and dirty diffusers dropping dust into rooms, we can put it right, from toilet extract systems, offices and schools and hospitals and care homes onwards.
London buildings tend to keep their plant on the roof or below ground, so work in Hendon is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
For insurers and inspectors, the record counts. 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.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Keep vents and grilles clear of shelving and stock
- Stick to the filter change schedule
- Get leaks near ductwork fixed quickly
- Keep the TR19 certificate and photo report in the maintenance log
Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.
Protect the system during building work by turning it off or covering the openings.
When it’s something else
Not every problem is solved by ventilation duct cleaning, and we’d rather say so up front. It doesn’t solve:
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Damaged ductwork beyond cleaning
- Controls and BMS faults that affect the system
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we will tell you honestly before booking.

Hendon questions
Can ventilation in schools around Hendon be cleaned out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 44 schools and colleges with food registrations within roughly a mile and a half of Hendon. Just give us a ring on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Do you work at weekends in Hendon?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
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 does TR19 Air differ from TR19 Grease?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, beyond the kitchen. It’s risk-based and led by inspection, and kitchen extract falls under TR19® Grease.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Do you survey the system first?
Yes, on every job. The survey shows the layout, the access and the condition, so the quote is fixed before any work starts.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
How long does ventilation cleaning take?
Expect it to take anything from a single shift for a small office to a planned programme of nights for a large building. How much ductwork there is and how easily it’s reached decide the rest.
What happens if it’s left?
If a building in Hendon has just been refitted, now is the time to clean the ductwork. Otherwise construction dust left in the ducts is blown out once the system runs. A booked night’s work in Hendon costs you no trading time; an unplanned closure does.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
