AHU cleaning for kitchens and businesses in Pollards Hill
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you’re dealing with plant that has been serviced but not cleaned and intake sections clogged with outdoor debris, we can put it right, from heating and cooling coils, supply and extract fans and filter sections onwards.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Pollards Hill.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.
Common problems we fix in Pollards Hill
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Pollards Hill, that’s air they breathe for hours at a time.
Most sites get in touch after spotting one of these:
- Units needing a clean before a new tenant or handover
- Intake sections clogged with outdoor debris
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
If you manage a school such as Kensington Avenue Primary School, ventilation cleaning is best booked for the holidays.

Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Choosing the date yourself beats having a fault choose it for you.

The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Security desks and permits-to-work are routine in London, so let us know what your building in Pollards Hill needs from us.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Mention any parking or loading restrictions
- Find the previous report, if there is one

What affects the cost of AHU cleaning
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Working hours and out-of-hours timing
- A single visit or a regular plan
- How big the system is
- The condition we find in the survey
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.
What to send for a quote
We can often survey from pictures. The most useful are:
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
- Problems your staff have spotted
- The times we could work without disrupting the site
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What else we do in Pollards Hill
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Make sure condensate is draining away
- Report water on the plant room floor
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
