About our ventilation duct cleaning in Clapham
Every ventilation system has ducts bringing air in and ducts taking it out. Dust and debris build up in both, some of which ends up back in the rooms. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. The work covers offices and schools, hospitals and care homes and toilet extract systems, and the jobs we see most are ductwork that hasn’t been inspected and dust marks around grilles and ceiling diffusers.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Clapham is usually planned out of hours. Parking and loading are agreed with the building in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, and that takes anything from a single shift for a small office to a planned programme of nights for a large building. Most London sites cannot stop for the day, so work in Clapham is typically done overnight, early in the morning or at weekends.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- After photos are taken and the certificate and report issued.
Getting ready for the visit
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet

Advice
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
How we price ventilation duct cleaning
The survey tells us what the work involves. The main factors are:
- Whether we need access equipment or extra panels
- The number of sites or systems
- Site requirements such as sign-in and permits
- Parking and loading at the site
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
Asking for a quote
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Problems your staff have spotted
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Clapham buildings and their air
The FSA’s food hygiene register lists about 54 schools, colleges and universities, about 62 hospitals, care homes and childcare premises and about 10 hotels and guest houses with registered kitchens or food service in and around Clapham, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. For Clapham, the closest hospital is Battersea General Hospital, roughly 1.3 miles north-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
If you manage offices or shops near Clapham High Street station, their ventilation can be inspected and cleaned out of hours. For schools like Clapham Manor Primary School, the holidays are the usual time to inspect and clean ventilation.

Aftercare tips
After the visit, a few habits help the work last:
- Stick to the filter change schedule
- Flag any dust coming out of the vents
- Don’t block grilles with furniture or storage
- Diary the next TR19® Air inspection
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Year on year, it shows how fast dust builds up.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
What ventilation duct cleaning can’t fix
Ventilation duct cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- A system that isn’t designed to move enough air
- Damaged ductwork beyond cleaning
- Problems with how the system is controlled
If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- General extract ductwork
- Offices and schools
- Grilles and diffusers
- Hospitals and care homes
- Toilet extract systems
- Supply ductwork
Leave it or put it right?
A clean system moves air more easily, which puts less load on the fans. Dirty ducts make the whole system work harder. It’s better booked as a planned job in Clapham than handled as an emergency.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.

Your questions about ventilation duct cleaning in Clapham
Can you work in Clapham outside opening hours?
Yes, we can come after you close and finish before you open. The work in Clapham can fit around your hours. Your opening times are the first thing we ask for.
How do you handle parking and loading in Clapham?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
How much does ventilation duct cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How often should ventilation ductwork be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Can you quote from pictures?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Nearby places to Clapham
What else we do in Clapham
Do you need ventilation duct cleaning in Clapham?
Most ductwork is out of sight, so nobody sees the build-up. The grilles get a wipe, but what’s behind them doesn’t.
Keep an eye out for any of the following:
- Supply ducts with years of dust inside
- Musty smells from the ventilation
- Ducts that need a clean before handover
- Ductwork with too few access panels to clean
If you run a surgery, dental practice or care home near Clapham, clean ventilation matters as much to you as to a hospital like Battersea General Hospital (about 1.3 miles north-west).
