AHU cleaning for kitchens and businesses in Poyle
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers filter sections, heating and cooling coils and internal panels, and the jobs we see most are stale or musty smells from the ventilation and plant that has been serviced but not cleaned.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Visits to a village like Poyle are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Different parts, different methods
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
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.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Poyle buildings and their air
There are about 4 care, childcare and hospital premises and about 10 hotels, B&Bs and guest houses on the FSA’s food hygiene register within roughly a mile and a half of the centre of Poyle. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. We cover Poyle, about 18 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. The nearest hospital to Poyle is Harlington, about 2.9 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage a school such as Pippins School, ventilation cleaning is best booked for the holidays.

What we are called out for in Poyle
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
- Air handling units with blocked filters
- Intake sections clogged with outdoor debris
Healthcare ventilation, from large hospitals like Harlington (about 2.9 miles east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book

Poyle questions
Can you come to Poyle after we close?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Poyle needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Poyle?
Yes. Poyle is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, and you can call 0345 646 2711 or drop us a line to plan it.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Why act early in Poyle
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Rural sites cannot always move to another kitchen or room when something fails.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.
