About our AHU cleaning in Hardwick
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. Common call-outs are for drain trays holding standing water and odours coming through the supply air, on drain trays, supply and extract fans and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Your questions about AHU cleaning in Hardwick
Do you cover smaller places like Hardwick?
Yes, Hardwick is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you clean school ventilation in Hardwick in the holidays?
Yes, holiday work suits schools best. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Hardwick, it pays to plan holiday dates ahead. You can call 0345 646 2711, or email photos with the dates the site is empty.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
How long does it take to clean an air handling unit?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
Managing agents and facilities teams in Hardwick
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 to a regular schedule.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Common problems we fix in Hardwick
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.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
School buildings such as Old School Room Chapel are normally done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- How areas they can’t reach will be recorded
- Whether VAT is included
- Whether a survey comes first
- What hours they’ll be on site

What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Hardwick and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms
- Have your last certificate or report to hand
Get a fixed quote
Some systems can be priced from photos; others need a survey. 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 we start.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Report water on the plant room floor
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, along with anything we couldn’t reach. 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 cost of AHU cleaning
Your quote is based on your site. We take into account:
- A single visit or a regular plan
- Any permits to work or inductions
- The condition we find in the survey
- How easy every part is to reach
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
When you call or email, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
What your team can do, and what needs us
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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
