How we handle AHU cleaning in Bletchley and Fenny Stratford
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. If you’re dealing with condensate trays that won’t empty and plant that has been serviced but not cleaned, we can help, from drain trays, internal panels and dampers and louvres onwards.
For a school, surgery or office in Bletchley and Fenny Stratford, cleaning is planned around opening hours: evenings, weekends or school holidays.
The paperwork matters as much as the work. You get a written report with pictures after every visit, 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 to hand when an insurer or inspector asks.

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, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

- What state the system is in
- One-off work versus a regular cycle
- Whether several sites go on one quote
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
When you contact us, these details help:
- Wide photos of the system and the area around it
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to

What the work involves, part by part
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.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
What happens on the day
Your staff do not need to do much 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. A closed day, an evening or an early start: whichever suits your site in Bletchley and Fenny Stratford, we’ll book around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
