AHU cleaning for kitchens and businesses in New Cross
Our AHU cleans for sites in New Cross cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. Common call-outs are for air handling units with blocked filters and units needing a clean before a new tenant or handover, across internal panels, supply and extract fans and heating and cooling coils.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in New Cross.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
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, which is where we come in.

Why act early in New Cross
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

How it works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We fit London jobs around the building rather than the other way round, so a visit in New Cross is usually out of hours.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site

Different parts, different methods
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Whether we need access equipment or extra panels
- What state the system is in
- Travel, parking and unloading
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Common problems we fix in New Cross
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Plant that has been serviced but not cleaned
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
- Plant that needs cleaning after a refit
For workplaces around New Cross station with mechanical ventilation, cleaning can be done in the evening or at weekends.
