Leave dust in the ductwork and it keeps building. Every year adds to the job, and more of it finds its way back into the building. A booked night’s work in Clerkenwell costs you no trading time; an unplanned closure does.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Ventilation duct cleaning in Clerkenwell
In a building in Clerkenwell, the people inside spend hours breathing what the ventilation delivers. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. We are often asked to deal with ventilation that needs a TR19® Air inspection and damp or stale smells from grilles, across grilles and diffusers, toilet extract systems and supply ductwork.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Clerkenwell, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
A written report with pictures follows each visit, 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.

Clerkenwell buildings and their air

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. The nearest hospital to Clerkenwell is Finsbury Health Centre, about within half a mile west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
For workplaces around Farringdon station with mechanical ventilation, cleaning can be done in the evening or at weekends. School buildings such as St Peter and St Paul RC Primary School are normally done in the holidays, so classrooms are not disturbed.

Signs you need ventilation duct cleaning in Clerkenwell
Even good filters let some dust through, so fine dust settles in supply ductwork over the years. Extract ducts pick up dust, fibres and fluff from the rooms they serve.
Most sites get in touch when they notice something like this:
- Stuffy rooms and stale air
- Supply ducts with years of dust inside
- Ducts that need a clean before handover
- Damp or stale smells from grilles
Hospitals such as Finsbury Health Centre (about within half a mile west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Clerkenwell are no different.

How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes from one overnight visit to a phased programme over several weeks. In a London area like Clerkenwell, parking, loading and building access are planned before the day of the work.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After photos are taken and the certificate and report issued.
How to prepare
- Mention any sign-in, permit or induction we need
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area

Related advice
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Store cleaning certificates where auditors can find them
- Tell your facilities team about dirty diffusers
- Keep to the inspection interval in your report
- Report leaks or damp near ceilings and risers
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Put it in the diary now so it isn’t missed.
Deal with condensation and leaks near ducts promptly, as wet dust is much harder to clean.
Clerkenwell questions
Can the work in Clerkenwell be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Clerkenwell keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Do you clean school ventilation in Clerkenwell in the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 69 schools and colleges with food registrations within roughly a mile and a half of Clerkenwell. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Is TR19 cleaning required by law?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Will we have paperwork to show the system was cleaned?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Is Clerkenwell in your area?
Yes. Our technicians work in Clerkenwell, as part of our area across London and the South East.
How do you deal with ducts you can’t get into?
Those sections are recorded as not cleaned in the report, with the reason. We can fit new access panels so they’re covered next time.
