AHU cleaning for kitchens and businesses in Hanworth
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have odours coming through the supply air and drain trays holding standing water, we can put it right.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Hanworth is normally planned out of hours. Loading and parking are planned with the building first.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What the work involves, part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
When something else is needed
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before booking.

AHU cleaning around Hanworth
There are about 17 schools, colleges and universities and about 21 hospitals, care homes and childcare premises on the FSA’s food hygiene register within roughly a mile and a half of the centre of Hanworth. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. London plant rooms are often on roofs or in basements reached through occupied floors. About 1.8 miles east of Hanworth is Teddington Memorial Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
For schools like Buckingham Primary School, the holidays are the usual time to inspect and clean ventilation.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Questions from Hanworth
Can a school’s ventilation in Hanworth be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Hanworth. Just ring 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
What do you need to know about parking in Hanworth?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call us on 0345 646 2711, or send details by email.
Is a quote from pictures possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. Some sites still need a visit, and we’ll say so.
Do you work evenings or weekends?
Yes, if daytime working isn’t practical. We plan the shutdown window with you.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where needed.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. In a London area like Hanworth, parking, loading and building access are planned before the day of the work.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive

Related advice
Between visits
Good habits slow the build-up between visits. Our tips:
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
- Check the drain tray is emptying during routine visits
- Stick to the filter change plan
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Landlords, agents and facilities managers
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 on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What we are called out for in Hanworth
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us include:
- Dirty coils holding back the airflow
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
Teddington Memorial Hospital, about 1.8 miles east, is the nearest hospital to Hanworth, and healthcare sites of every size need their supply air kept clean.
