How we handle AHU cleaning in Plaistow
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, drain trays and supply and extract fans, and common reasons people get in touch are dirty coils holding back the airflow and leaves and litter drawn into the unit.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Plaistow is normally planned out of hours. Loading and parking are planned with the building first.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about AHU cleaning in Plaistow
Can ventilation in schools around Plaistow be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 21 schools and colleges with food registrations within roughly a mile and a half of Plaistow. Booking early in the term gives the best choice of holiday dates.
Can parking be tricky for a job in Plaistow?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.
What happens if you cannot reach some of it?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you work in Plaistow?
Yes. Our area takes in London and the counties of South East England, Plaistow included.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Looking after it afterwards
After the visit, a few habits help the work last:
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Do not store bins or materials near the intake
- Diary the inspection date recommended in the report
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
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. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
What we’re called out for in Plaistow
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’s the air they breathe for hours on end.
Keep an eye out for these warning signs:
- Dust built up on fan impellers
- Dirty filters cutting the airflow
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
If you manage offices or shops near Sundridge Park station, their ventilation can be inspected and cleaned out of hours.

- Whether the quote shows VAT
- If they look at the system before pricing
- Which accreditations they hold, and whether you can check them
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Security desks and permits-to-work are routine in London, so let us know what your building in Plaistow needs from us.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures 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.
- We take after photos and issue the certificate and report.
How to prepare
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.
