About our ventilation duct cleaning in City of London
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts pick up whatever gets past the filters. Both are cleaned, with the area protected and the mess contained. We’re often asked to deal with dust marks around grilles and ceiling diffusers and systems with no record of inspection or cleaning, on offices and schools, supply ductwork and toilet extract systems.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in City of London.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, clear away and hand over the paperwork. The visit itself takes a weekend for a modest system, with large buildings phased floor by floor. Most London sites cannot stop for the day, so work in City of London is usually done overnight, early in the morning or at weekends.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Agree a time when the area can be out of use
- Clear the space around the work

The quickest way to a quote is to send pictures: 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 many jobs can be priced from that alone.
Advice
Common questions in City of London
Can ventilation in schools around City of London be cleaned out of term?
Yes, holiday work suits schools best. With about 90 schools and colleges on the FSA’s register within roughly a mile and a half of City of London, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can parking be tricky for a job in City of London?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
How often should ventilation ductwork be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Busy or sensitive buildings may need it more often.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

What affects the cost of ventilation duct cleaning
There’s no set price list, because sites vary so much. What we look at:
- The scale of the work
- The times the site is available
- A single visit or a regular plan
- Where the site is and how we reach it
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What to send for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Wide photos of the system and the area around it
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
How the job changes from site to site
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
Supply ductwork
We check supply ducts at intervals along each run to see where cleaning is needed.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

There are about 90 schools, colleges and universities, about 63 care, childcare and hospital premises and about 129 hotels and B&Bs on the FSA’s food hygiene register within 1.5 miles or so of the middle of City of London. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 0.6 miles south-east of City of London is London Bridge Hospital, the nearest hospital. 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 normally means lifts, stairs and an agreed loading slot.

Signs you need ventilation duct cleaning in City of London
In a building in City of London, the ventilation may run for long hours every day, and every hour of running brings more dust with it. Heavier use means faster build-up.
If you notice any of these, it’s worth a diagnosis:
- Ductwork that hasn’t been inspected
- Dust marks around grilles and ceiling diffusers
- Dusty supply ductwork that hasn’t been cleaned in years
- Damp or stale smells from grilles
If you run an office near London Cannon Street station, its supply ductwork can gather dust for years before anyone looks inside.
