AHU cleaning for kitchens and businesses in Aperfield
We clean air handling units for buildings in Aperfield and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers supply and extract fans, dampers and louvres and drain trays, and common reasons people get in touch are dirty coils holding back the airflow and intake sections clogged with outdoor debris.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Aperfield is normally planned out of hours. Loading and parking are planned with the building first.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Signs you need AHU cleaning in Aperfield
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Clients usually contact us when they notice something like this:
- Dust-coated heating and cooling coils
- Units needing a clean before a new tenant or handover
- Odours coming through the supply air
- Drain trays holding standing water
Healthcare buildings such as Warlingham Park Hospital, about 3.4 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Aperfield, yours matters too.
Comparing quotes
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the work can be done while the site is closed
- What happens if part of the system can’t be accessed
- Whether they recommend a next date
Looking after it afterwards
Once we have finished, these simple steps help:
- Change filters on schedule and log each change
- Keep the certificate and photo report with the plant records
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
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.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

What affects the quote in Aperfield
We quote each job individually. This is what makes a difference:
- The size of the system
- Working hours and out-of-hours timing
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
When you call or email, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, ring 0345 646 2711 or drop us a line.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
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.
When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. A name and number for whoever controls access to the building in Aperfield saves time on the night.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
