AHU cleaning for kitchens and businesses in Calshot
If the units serving a building in Calshot have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you are dealing with dirty fans and fan housings and dirty filters cutting the airflow, we can help.
In a village or hamlet like Calshot, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a dated report with photos 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.

How the visit 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. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Calshot, tell us about narrow lanes, gates and parking when you book.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Your questions about AHU cleaning in Calshot
Can you do AHU cleaning in Calshot?
Yes. Our area runs across London and the South East, Calshot included. A fixed quote usually follows within one working day of the survey details.
Will you come out to Calshot?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply phone us on 0345 646 2711 or email us.
Why deal with it now?
A slimy drain tray only gets worse. 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. In a small place like Calshot, a system that fails can take a site out of use.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

Common problems we fix in Calshot
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
If you notice any of these, it’s worth a diagnosis:
- Coils clogged with dust and debris
- Stale or musty smells from the ventilation
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
If you run a surgery, dental practice or care home near Calshot, clean ventilation matters as much to you as to a hospital like Coldeast (about 4.5 miles north-east).

Fixed quotes for AHU cleaning in Calshot
The quote reflects the site in front of us. We take into account:
- Travel, parking and unloading
- The number of sites or systems
- A single visit or a regular plan
- Site requirements such as sign-in and permits
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
When you contact us, these details help:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

What else we do in Calshot
In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
