How we handle AHU cleaning in Bradenham
Our AHU cleaning covers sites in Bradenham and the rest of Buckinghamshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers drain trays, filter sections and internal panels, and people most often call us about air handling units with blocked filters and units needing a clean before a new tenant or handover.
For a building in or near Bradenham, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

FAQs for Bradenham
Do you clean school ventilation in Bradenham in the holidays?
Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bradenham. Just phone us on 0345 646 2711 or email us with your term dates and we will plan around them.
Can you come to Bradenham after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Bradenham keeps running as normal. Tell us your opening hours when you ask for a quote.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you need to switch the unit off?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do you work in Bradenham?
Yes. We work in Bradenham and the rest of Buckinghamshire, as part of our work across South East England and London. To book, call us on 0345 646 2711, or email photos.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711 or email us and tell us about the site and its opening hours.
What affects the quote in Bradenham
There’s no set price list, because sites vary so much. The quote depends on:
- How many systems or sites are involved
- The scale of the work
- Any permits to work or inductions
- What state the system is in
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before work begins.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then call 0345 646 2711, or send details by email.
What we do, step by step
On the day, we arrive 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 before any work starts, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Bradenham are booked in advance, at a time that suits whoever runs the site.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
Getting a 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.
Advice
When something else is needed
Before you book, it helps to know what’s not included:
- Leaking heating or cooling coils
- Ventilation that was badly designed in the first place
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can call 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
What we work on in Bradenham
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Internal panels
- Supply and extract fans
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Out of sight is the usual reason a rural system goes too long without attention.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.

What AHU cleaning looks like in Bradenham
Going by the FSA’s register, there are about 5 care, childcare and hospital premises serving food in and around Bradenham, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 33 miles from central London, Bradenham sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. For Bradenham, the closest hospital is Wycombe Hospital, roughly 3.5 miles south-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
If you manage a school such as Naphill and Walters Ash School, ventilation cleaning is best booked for the holidays. Wycombe Hospital, about 3.5 miles south-east, is the nearest hospital to Bradenham, and healthcare sites of every size need their supply air kept clean.

In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
