Common questions in Millbank
Do you clean school ventilation in Millbank in the holidays?

How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711, or email photos and tell us about the site and its opening hours.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
Is Millbank in your area?
Yes. We cover Millbank and across Greater London, as part of our work across South East England and London. To book, give us a ring on 0345 646 2711, or send details by email.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
AHU cleaning in Millbank, done properly
Our AHU cleans for sites in Millbank cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include leaves and litter drawn into the unit and fan sections that haven’t been cleaned in years, across drain trays, internal panels and heating and cooling coils.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Millbank, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Getting kit into a London building takes planning, so let us know where we can load and park in Millbank.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- 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
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
How to get a quote
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.

When to call us in Millbank
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Most sites get in touch when they notice one of these:
- Intake sections clogged with outdoor debris
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
- Stale or musty smells from the ventilation
For schools like Harris Westminster Sixth Form, the holidays are the usual time to inspect and clean ventilation.
Before booking anyone
- Proof of accreditation you can verify
- Whether they recommend a next date
- How VAT is shown on the quote
- Whether the whole system is included, or only the parts that are easy to reach
Looking after it afterwards
So the system stays in good health:
- Report musty smells from the vents right away
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
- Keep the certificate and photo report with the plant records
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
How we price AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- Parking and loading at the site
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
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 the price is fixed before any work starts.
What to send for a quote
We can often survey from pictures. The most useful are:
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- When the site is open and when it’s quiet
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Building management system faults
- The supply and extract ducts, quoted separately
- Leaking heating or cooling coils
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think before you book.
Parts of the system we cover
- Internal panels
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Filter sections
What the work involves, part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. 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 call for the right kit, training and safe access. Leave those to us.
