AHU cleaning in Seasalter
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include leaves and litter drawn into the unit and units needing a clean before a new tenant or handover, across drain trays, dampers and louvres and filter sections.
In a village or hamlet like Seasalter, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Why it’s worth doing now in Seasalter
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A planned visit to Seasalter is easier to arrange than an emergency callout.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
- Report water on the plant room floor
- Clear leaves and litter away from the intake
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Common problems we fix in Seasalter
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Any of these means the system needs a check-up:
- Dirty fans and fan housings
- Dirty coils holding back the airflow
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
Whitstable and Tankerton Hospital, about 2.5 miles north-east, is the nearest hospital to Seasalter, and healthcare sites of every size need their supply air kept clean.
Questions to ask before you book
- Proof of insurance
- Whether the figure could change on the day
- What hours they’ll be on site
- How areas they cannot reach will be recorded
AHU cleaning in Seasalter: local notes
Food Standards Agency records list about 6 schools, colleges and universities and about 11 hospitals, care homes and childcare premises registered as food businesses within roughly a mile and a half of the centre of Seasalter. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 2.5 miles north-east of Seasalter is Whitstable and Tankerton Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Seasalter, about 48 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
For schools like Joy Lane Primary Foundation School, the holidays are the usual time to inspect and clean ventilation.

How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Seasalter run smoothly.
- 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 pictures and issue the certificate and report.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. 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 the job changes from site to site
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
