Different parts, different methods
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.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
How we handle AHU cleaning in Bapchild
If the units serving a building in Bapchild have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you’re dealing with units needing a clean before a new tenant or handover and filters that are clogged or overdue, we can put it right, from internal panels, dampers and louvres and drain trays onwards.
In a village or hamlet like Bapchild, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. You get a written report with photos 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.

Looking after it afterwards
After the visit, a few habits help the work last:
- Report water on the plant room floor
- Do not ignore odours coming through the grilles
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
When it’s something else
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It doesn’t solve:
- A system that is undersized for the building
- Breakdowns that need a mechanical engineer
- Coils that are corroded or leaking and need replacing
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

Bapchild: your questions answered
Do you cover smaller places like Bapchild?
Yes. Bapchild is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Bapchild?
Yes, out-of-hours work is a big part of what we do. That way a site in Bapchild doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How long will the unit be out of action?
The work takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, so call us on 0345 646 2711, or send details by email to talk it through.
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Why deal with it now?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Equipment tucked in a roof space or outbuilding near Bapchild rarely gets looked at unless someone books it.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

Other services in Bapchild
How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- How big the system is
- Parking and loading at the site
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
Before you ask for a quote, gather:
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- Your last certificate, test record or report
- A few general shots of the system
Some systems can be priced from photos; others need a survey. 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.

How it works

The work itself takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Bapchild.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
