How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from one overnight visit to a phased programme over several weeks. If your building in Blackfriars has sign-in rules, permits or key holders, mention them when you book.
- We survey the system from drawings, pictures or a site visit.
- Inspection comes next, with photos of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- You get a TR19® certificate and photo report, with any unreached sections noted.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work

Ventilation duct cleaning in Blackfriars, done properly
Supply ducts carry air into the rooms and extract ducts take it away. Dust and debris build up in both, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. The work covers toilet extract systems, grilles and diffusers and general extract ductwork, and people most often call us about ventilation that needs a TR19® Air inspection and poor airflow from the vents.
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 Blackfriars, dust and debris build up in the units and ductwork over time.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Your questions about ventilation duct cleaning in Blackfriars
Can you clean school ventilation in Blackfriars during the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 76 schools, colleges and universities with registered kitchens within about a mile and a half of Blackfriars. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you handle parking and loading in Blackfriars?
A loading bay, a visitor permit or off-street space near the site in Blackfriars makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
What does ventilation duct cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, typically ready within one working day.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Can you clean ventilation out of hours?
Yes, where the building needs it. We agree a window when the ventilation can go off.
Are you insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What happens if parts of the ductwork can’t be reached?
The report shows exactly which parts weren’t reached. Access panels can be added where necessary.
Between visits
Good habits slow the build-up between visits. Our tips:
- Book the next inspection on the date the report recommends
- Report dust blowing from grilles right away
- Get leaks near ductwork fixed quickly
- Keep vents and grilles clear of shelving and stock
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Don’t let construction dust into the ventilation by turning it off or covering the openings.

Managing agents and facilities teams in Blackfriars
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

What the work involves, part by part
Grilles and diffusers
Grilles and diffusers that are designed to come out are removed for cleaning, then refitted.
Hospitals and care homes
Hospitals and care homes are occupied day and night. The work is sequenced with staff to keep disruption down.
When to call us in Blackfriars
Moisture in ducts makes dust stick. Where there’s condensation or a leak, dust clings and builds faster, which is harder to shift later.
Most sites get in touch when they notice something like this:
- Systems with no record of inspection or cleaning
- Blocked general extract ductwork
- Grilles and diffusers streaked with dirt
- Duct runs that cannot be reached for cleaning
If you run a surgery, dental practice or care home near Blackfriars, clean ventilation matters as much to you as to a hospital like St Philip's Hospital (about 0.6 miles west).
