Ventilation duct cleaning in Bishopsgate, done properly
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. The work covers grilles and diffusers, general extract ductwork and supply ductwork, and people most often call us about ventilation that needs a TR19® Air inspection and musty smells from the ventilation.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Bishopsgate, dust and debris build up in the units and ductwork over time.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Diary the next TR19® Air inspection
- Wipe grilles and diffusers during routine cleaning
- Watch for water stains around grilles
- Keep vents and grilles clear of shelving and stock
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Deal with condensation and leaks near ducts promptly, as moisture makes dust stick.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What the work involves, part by part
Grilles and diffusers
Where they come out, grilles are taken down and cleaned, then refitted.
Hospitals and care homes
In healthcare and care settings, there’s no quiet time. The work is sequenced with staff so care carries on.
How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a shift or two for a small system, longer for a whole building. A name and number for whoever controls access to the building in Bishopsgate saves time on the night.
- First the system is surveyed, on site or from pictures and drawings.
- Inspection comes next, with pictures of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned off.
- Dust and debris are removed from ducts, grilles and diffusers.
- A certificate and before and after pictures follow, with anything not reached recorded.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
How to get a quote
Photos are the quickest way to a quote: 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.
Related advice
Leave it or put it right?
Landlords, tenants and auditors may want proof the ventilation is looked after. A TR19® certificate and photo report from a recent clean give them that. A booked night’s work in Bishopsgate costs you no trading time; an unplanned closure does.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.

Bishopsgate buildings and their air
Food Standards Agency data includes about 96 schools, colleges and universities, about 65 hospitals, care homes and childcare premises and about 88 hotels and B&Bs within 1.5 miles or so of the middle of Bishopsgate. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Bishopsgate, the closest hospital is London Bridge Hospital, roughly 0.7 miles south. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
Workplaces around London Liverpool Street station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. School buildings such as The London School of Barbering are usually done in the holidays, so classrooms aren’t disturbed. If you run a surgery, dental practice or care home near Bishopsgate, clean ventilation matters as much to you as to a hospital like London Bridge Hospital (about 0.7 miles south).

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Bishopsgate questions
Do you clean school ventilation in Bishopsgate in the holidays?

How do you deal with ducts you cannot get into?

We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.
