AHU cleaning for kitchens and businesses in Shadwell
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers drain trays, heating and cooling coils and supply and extract fans, and common reasons people get in touch are odours coming through the supply air and plant that has been serviced but not cleaned.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Shadwell is normally planned out of hours. Parking and loading are agreed with the building in advance.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Diary the inspection date recommended in the report
- Report musty smells from the vents right away
- Keep the area around the fresh air intake clear
- File each AHU report in the maintenance log
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Leave it or put it right?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Choosing the date yourself beats having a fault choose it for you.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

Do you need AHU cleaning in Shadwell?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
It’s time to book a visit if you see:
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
- Dirty coils holding back the airflow
School buildings such as Peter Hills with St Mary's and St Paul's CofE Primary School are usually done in the holidays, so classrooms aren’t disturbed.
Before you book anyone
- Exactly which parts of the system are covered
- Proof of accreditation you can verify
- When they can work, and whether that is outside your opening hours
- Proof of insurance
Your questions about AHU cleaning in Shadwell
Can you work in Shadwell outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Shadwell needn’t be disturbed. Just phone us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.
What do you need to know about parking in Shadwell?
Tell us where a van can stop near your site in Shadwell, and about any building rules on loading. Much of our London work is done overnight, which helps.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
How much does AHU cleaning cost in Shadwell?
Every site is different, so each gets its own fixed quote. To get one, phone us on 0345 646 2711 or email us and tell us about the site and its opening hours.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.

Going by the FSA’s register, there are about 95 schools, colleges and universities, about 62 care, childcare and hospital premises and about 30 hotels, B&Bs and guest houses serving food within 1.5 miles or so of the middle of Shadwell. Busy, occupied buildings like these are where clean supply air matters most. St Olave's Hospital is the nearest hospital, about 0.8 miles south-west of Shadwell.

Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- How easy every part is to reach
- What state the system is in
- One-off work versus a regular cycle
- Where the site is and how we reach it
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
