Ventilation duct cleaning in London, done properly
A dusty duct in a building in London is more than an eyesore. It slows the air, strains the fans and can be blown back out of the grilles. Cleaning restores the clear airway the system was designed with. The work covers general extract ductwork, grilles and diffusers and toilet extract systems, and people most often call us about rooms that feel airless when the system runs and ventilation full of debris from building work.
In a big place like London, one building can have several AHUs serving different zones. Each has filters, coils, a drain tray and a fan that need attention, and a drain tray holding water is something we look for on every unit.
A written report with photos follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Part by part
Supply ductwork
Anything in a supply duct can end up in the rooms it feeds. We clean the runs so it isn’t blown back in.
Hospitals and care homes
In care settings, keeping dust contained is a priority. We protect the work area and take everything away.
Ventilation duct cleaning in London: local notes
The FSA’s food hygiene register lists about 93 schools, colleges and universities, about 52 care, childcare and hospital premises and about 102 hotels and B&Bs with registered kitchens or food service within roughly a mile and a half of the centre of London. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For London, the closest hospital is Surrey Dispensary, roughly under half a mile south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot.
If you run a surgery, dental practice or care home near London, clean ventilation matters as much to you as to a hospital like Surrey Dispensary (about less than half a mile south-east). Classrooms and halls at schools such as Charles Dickens Primary School are easiest to work in when pupils are away.

London questions
How do you handle parking and loading in London?
A loading bay, a visitor permit or off-street space near the site in London makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Can ventilation in schools around London be cleaned out of term?
Yes. The holidays are the usual time for school work. With about 93 schools and colleges on the FSA’s register within roughly a mile and a half of London, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or send us an email with your term dates and we will plan around them.
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.
Are grilles and diffusers included?
Yes. Grilles and diffusers are cleaned as part of the job, so dust isn’t left at the outlets.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Will we have paperwork to show the system was cleaned?
Yes. You get a certificate with the date, location and technician, along with pictures before and after.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Why act early in London
Dust in ducts doesn’t go away on its own. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. The longer a system in London goes without attention, the more there is to clean or fix.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

See our cost guide and how to check a contractor.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a day or less for a small system and a series of visits for a large one, and the area is cleaned down before we leave. Town-centre sites in a place like London can be tight for parking, so it helps to know the options in advance.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- After pictures are taken and the certificate and report issued.
How to prepare
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Keep to the inspection interval in your report
- Watch for water stains around grilles
- Don’t run the ventilation while builders are sanding or cutting
- Stick to the filter change schedule
Share the report with whoever looks after the building’s maintenance, so the history stays together. Year on year, it shows how fast dust builds up.
TR19® Air works through regular inspection. Inspecting on a schedule catches build-up before it becomes a big clean.
When something else is needed
In fairness, there are a few things this work will not fix:
- Ducts that are damaged, corroded or leaking and need replacing
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- A system that isn’t designed to move enough air
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly.

What we’re called out for in London
Moisture in ducts makes dust stick. Condensation and leaks turn loose dust into a stubborn layer, which is harder to shift later.
It’s time to book a visit if you see:
- Poor airflow from the vents
- Systems with no record of inspection or cleaning
- Systems missing access panels
- Dusty supply ductwork that hasn’t been cleaned in years
Workplaces around Elephant & Castle station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
