AHU cleaning for kitchens and businesses in Upshire
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. We’re often asked to deal with filters that are clogged or overdue and dirty fans and fan housings, on filter sections, dampers and louvres and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Upshire
Some jobs are bigger than they look, and some smaller. The main factors:
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- The size of the system
- How many systems or sites are involved
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 you’ll get one fixed quote.
Asking for a quote
When you contact us, these details help:
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Honest limits
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Damaged coils beyond cleaning
- Building management system faults
If you’re not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer.

Between visits
Simple habits between visits make a real difference. We recommend:
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Upshire, let us know and we’ll plan around it.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
- Make sure equipment near the work can be switched off and left to cool

What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. A fault that closes a site in a village like Upshire affects everyone who depends on it.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.

Ventilation in Upshire buildings
There are about 7 care, childcare and hospital premises on the FSA’s food hygiene register across Upshire and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Upshire, the closest hospital is St. Margaret's Hospital, roughly 3.5 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. At about 15 miles from central London, Upshire sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
If you manage a school such as Upshire Primary Foundation School, ventilation cleaning is best booked for the holidays.

Common problems we fix in Upshire
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Look out for any of the following:
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
Healthcare buildings such as St. Margaret's Hospital, about 3.5 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Upshire, yours matters too.

Your questions about AHU cleaning in Upshire
Do you work at weekends in Upshire?
Yes, evening, overnight and weekend work is normal for us. That way a site in Upshire does not have to lose a day’s trading. When you ring 0345 646 2711, or email photos, mention when the site is quiet.
Do you cover smaller places like Upshire?
Yes, Upshire is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Is a quote from pictures possible?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How long will the unit be out of action?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
