About our AHU cleaning in Little London
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. Clearing and cleaning the tray is central to every AHU clean. The work covers heating and cooling coils, internal panels and supply and extract fans, and people most often call us about dust-coated heating and cooling coils and units needing a clean before a new tenant or handover.
For a building in or near Little London, access is agreed in advance and the visit is planned around the journey.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What AHU cleaning looks like in Little London

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
Managing agents and facilities teams in Little London
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
When to call us in Little London
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Little London, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
Healthcare ventilation, from large hospitals like St. Luke’s Hospital (about 4.1 miles north-west) to small clinics, depends on clean filters, coils and ducts.

- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.

What the work involves, part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.

How we price AHU cleaning
Sites vary more than people expect. The main factors:
- Working hours and out-of-hours timing
- How big the system is
- Whether several sites go on one quote
- Travel, parking and unloading
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Helping us quote
To speed up the quote, please include:
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call us on 0345 646 2711 or drop us a line.
Little London questions
Do you cover smaller places like Little London?
Yes, Little London is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can ventilation in schools around Little London be cleaned out of term?
Yes, holiday work suits schools best. Around Little London, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How long does an AHU clean take?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What a clean won’t put right
It’s worth knowing the limits before booking:
- A system that’s undersized for the building
- Building management system faults
- Damaged coils beyond cleaning
