For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
About our AHU cleaning in Kingsash
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers supply and extract fans, drain trays and filter sections, and common reasons people get in touch are dust built up on fan impellers and blocked condensate drains and slimy trays.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Do you need AHU cleaning in Kingsash?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
The symptoms we’re asked about most include:
- Blocked condensate drains and slimy trays
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
- Air handling units due a clean after building work
Classrooms and halls at schools such as Wendover House School are easiest to work in when pupils are away.

Fixed quotes for AHU cleaning in Kingsash
You will get a fixed price before any work starts. It takes into account:
- A single visit or a regular plan
- The condition we find in the survey
- How easy every part is to reach
- Where the site is and how we reach it
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Kingsash, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- 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
- Find the previous report, if there is one
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Why it’s worth doing now in Kingsash
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. In a small place like Kingsash, a system that fails can take a site out of use.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.
