What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
How we handle AHU cleaning in Wandsworth
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have rooms that smell stuffy when the system runs and debris and leaves in the fresh air intake, we can help.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Wandsworth is usually planned out of hours. Parking and loading are agreed with the building in advance.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What we do, step by step
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We fit London jobs around the building rather than the other way round, so a visit in Wandsworth is typically out of hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Clear the space around the work
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
How to get a quote
Getting a quote doesn’t take long. Send a few details and photos, 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
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
What we’re called out for in Wandsworth
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Clients typically contact us when they notice something like this:
- Air handling units with blocked filters
- Air handling units due a clean after building work
- Coils clogged with dust and debris
- Dirty fans and fan housings
If you manage shops or offices close to Wandsworth Town station, a TR19® Air inspection shows whether the ductwork needs cleaning.
What your quote should include
- What paperwork you get at the end
- Whether they’re fully insured
- Whether VAT is included
- If the quote is a fixed price or an estimate
Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. London sites work long hours, and the longer a job is left, the bigger it gets.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
Why book with us
- We diagnose before we treat
- We are fully insured
- Work around your opening hours, with 24/7 emergency cover
- Fixed quotes, typically within one working day

Common questions in Wandsworth
Can parking be tricky for a job in Wandsworth?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can the work in Wandsworth be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Wandsworth doesn’t have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
How long does an AHU clean take?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Do you cover Wandsworth?
Yes. We cover Wandsworth and the rest of Greater London, within our South East and London area. To book, call 0345 646 2711 or use the quote form.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Is a quote from photos possible?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
How we price AHU cleaning
The price is fixed before any work begins. It takes into account:
- How easy every part is to reach
- The condition we find in the survey
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
You don’t need the technical terms. Just send:
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
For AHU cleaning in Wandsworth, call 0345 646 2711 or email us. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote typically follows within one working day.
What AHU cleaning looks like in Wandsworth
The FSA’s food hygiene register lists about 33 schools, colleges and universities, about 72 caring premises (care homes, nurseries and hospitals) and about 9 hotels and B&Bs with registered kitchens or food service across Wandsworth and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Wandsworth is Royal Hospital for Neuro-disability, about 1 mile west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare ventilation, from large hospitals like Royal Hospital for Neuro-disability (about 1 mile west) to small clinics, depends on clean filters, coils and ducts. Wherever a school like St Anne's CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Wandsworth is about 3 miles south-west of Brompton, in Greater London. Every kind of commercial site in Wandsworth, we can take on AHU cleaning.

Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Report water on the plant room floor
- Stick to the filter change plan
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
