AHU Cleaning in Charter Alley
AHU cleaning across Charter Alley and nearby, timed so the site keeps working and finished with a written report and pictures.
- Leaves and litter drawn into the unit
- Stale or musty smells from the ventilation
- Condensate trays that will not empty
How we handle AHU cleaning in Charter Alley
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We are often asked to deal with rooms that smell stuffy when the system runs and filters that are clogged or overdue, across heating and cooling coils, drain trays and supply and extract fans.
Somewhere as small as Charter Alley, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
How it works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Charter Alley can be planned properly.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
How to get a quote
To get a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
Advice
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Report water on the plant room floor
- Plan the next inspection before the last report gets filed away
- Do not ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
The report shows each section of the unit before and after, and note any part we couldn’t get to. 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.
AHU cleaning in Charter Alley: local notes
About 2.7 miles south-east of Charter Alley is Park Prewett Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Charter Alley is about 47 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
Wherever a school like The Priory Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

When to call us in Charter Alley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Keep an eye out for these warning signs:
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
- Coils clogged with dust and debris
- Air handling units due a clean after building work
Healthcare ventilation, from large hospitals like Park Prewett Hospital (about 2.7 miles south-east) to small clinics, depends on clean filters, coils and ducts.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
Charter Alley questions
Do you do school ventilation cleaning in Charter Alley in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Charter Alley. Just call us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Do you work in villages like Charter Alley?
Yes. Charter Alley 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.
Can you quote from pictures?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Are you insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
