AHU cleaning in Little Warley, done properly
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. Clearing and cleaning the tray is central to every AHU clean. The work covers supply and extract fans, heating and cooling coils and internal panels, and the jobs we see most are fan sections that haven’t been cleaned in years and units needing a clean before a new tenant or handover.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Little Warley, let us know and we’ll plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- 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
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is 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. Leave those to us.
Little Warley questions
Can you get to a site in Little Warley?
Yes. Villages and rural sites across the South East are part of our work, Little Warley included. A survey first, from photos or a visit, means we arrive with the right kit.
Can the work in Little Warley be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Little Warley keeps running as normal. Let us know the hours you are closed and we will book within them.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can you quote from pictures?
Typically, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. If photos are not enough, we will survey first.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.

Signs you need AHU cleaning in Little Warley
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.
Look out for these warning signs:
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
Healthcare buildings such as Spire Hartswood Hospital, about 2 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Little Warley, yours matters too.
Before booking anyone
- Proof of insurance
- Whether the quote is based on a survey or photos
- What hours they’ll be on site
- Proof of accreditation you can verify
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
What affects the quote in Little Warley
Your quote is based on your site. We consider:
- Whether several sites go on one quote
- The scale of the work
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
What we need to know
We can often survey from pictures. Try to include:
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To get a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report musty smells from the vents right away
- Don’t store bins or materials near the intake
- Keep filter changes on time and recorded
- Book the next check in line with the report
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
