Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

AHU cleaning for kitchens and businesses in Puttenham
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Common call-outs are for air handling units with blocked filters and drain trays holding standing water, across supply and extract fans, dampers and louvres and heating and cooling coils.
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.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Puttenham buildings and their air
About 35 miles out from central London, Puttenham is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. Puttenham’s nearest hospital, Tindal Centre, is about 3.8 miles west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage a school such as Long Marston VA Church of England Primary School, ventilation cleaning is best booked for the holidays.
Puttenham is about 4 miles east of Aylesbury, in Hertfordshire. Every kind of commercial site in Puttenham, we can take on AHU cleaning. We can work out of hours so trading isn’t interrupted. Our Hertfordshire coverage runs to 381 places, and Puttenham is one of them. Our Milton Keynes page covers sites nearby (15 miles or so).
All of HP23 is covered for AHU cleaning, from busy streets to back roads. That includes premises on Church Road, Astrope Lane and Draytonmead Farm Road and the roads around them. We also cover the places around Puttenham: Astrope (1 mile east), Long Marston (1 mile north-east), Buckland (1 mile south), Aston Clinton (2 miles south) and Broughton (2 miles west). Further out, we also cover Hemel Hempstead (12 miles south-east), Berkhamsted (7 miles south-east), Tring (3 miles south-east), Chorleywood (15 miles south-east), Grovehill (12 miles south-east) and Woodhall Farm (12 miles south-east).
Around Puttenham
For rail, the closest station is Cheddington station, roughly 3.3 miles north-east. Other landmarks nearby include Tindal Centre (3.8 miles west) and Pitstone Green Museum (3.2 miles east). For a walk, there’s Haddington Hill and College Lake nature reserve.
Why it’s worth doing now in Puttenham
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Somewhere as small as Puttenham, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

What we’re called out for in Puttenham
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Any of these means the system needs a check-up:
- Units that have only ever had filter changes
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
- Blocked condensate drains and slimy trays
If you run a surgery, dental practice or care home near Puttenham, clean ventilation matters as much to you as to a hospital like Tindal Centre (about 3.8 miles west).

Puttenham: your questions answered
Do you work at weekends in Puttenham?
Yes, evening, overnight and weekend work is normal for us. That way a site in Puttenham doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Do you cover smaller places like Puttenham?
Yes. Puttenham is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Fixed quotes for AHU cleaning in Puttenham
The survey tells us what the work involves. We look at:
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- The condition of the system
- Where the site is and how we reach it
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
What we need to know
When you call or email, it’s useful to have:
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Book the next check in line with the report
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Puttenham are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- 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.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Clear the space around the work
