How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
AHU cleaning in Clapham Junction, done properly
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you’re dealing with dust-coated heating and cooling coils and rooms that smell stuffy when the system runs, we can put it right.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Clapham Junction is usually planned out of hours. Loading and parking are planned with the building first.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

- Ductwork downstream of the unit, which is a separate clean
- Building management system faults

AHU cleaning in Clapham Junction: local notes
The FSA’s food hygiene register lists about 34 schools, colleges and universities, about 71 caring premises (care homes, nurseries and hospitals) and about 12 hotels and guest houses with registered kitchens or food service within about 1.5 miles of central Clapham Junction. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. London plant rooms are often on roofs or in basements reached through occupied floors. About 0.8 miles north of Clapham Junction is Battersea General Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
For workplaces around Clapham Junction station with mechanical ventilation, cleaning can be done in the evening or at weekends. School buildings such as Christ Church CofE Primary School are usually done in the holidays, so classrooms aren’t disturbed.

What else we do in Clapham Junction
Landlords, agents and facilities managers
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 send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your questions about AHU cleaning in Clapham Junction
Can you clean school ventilation in Clapham Junction during the holidays?
Yes, and it’s the easiest time to do it. With about 34 schools and colleges on the FSA’s register within roughly a mile and a half of Clapham Junction, it pays to plan holiday dates ahead. Just call us on 0345 646 2711 or email us with your term dates and we will plan around them.
What do you need to know about parking in Clapham Junction?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you quote from photos?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
How the visit works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on.

Advice
Do you need AHU cleaning in Clapham Junction?
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
It’s time to book a visit if you see:
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
Battersea General Hospital, about 0.8 miles north, is the nearest hospital to Clapham Junction, and healthcare sites of every size need their supply air kept clean.

How we price AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- Site requirements such as sign-in and permits
- The size of the system
- Parking and loading at the site
- Working hours and out-of-hours timing
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- Your last certificate, test record or report
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, call 0345 646 2711 or use the quote form.
