For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
How we handle AHU cleaning in Swanbourne
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. Typical jobs include plant that has been serviced but not cleaned and drain trays holding standing water, across supply and extract fans, drain trays and dampers and louvres.
Somewhere as small as Swanbourne, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Common problems we fix in Swanbourne
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
What we’re most often called out for:
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Odours coming through the supply air
- Coils clogged with dust and debris
Healthcare ventilation, from large hospitals like Bletchley Community Hospital (about 5.4 miles north-east) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether the quote is based on a survey or pictures

- Whether VAT is included
- Proof of insurance
Fixed quotes for AHU cleaning in Swanbourne
We do not publish a price list, because no two systems are the same. What we look at:
- The condition of the system
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- Whether several sites go on one quote
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Problems your staff have spotted
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Why act early in Swanbourne
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Swanbourne simpler. Out of sight is the usual reason a rural system goes too long without attention.
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.
Why book with us
- Fixed quotes, normally within one working day
- Every visit written up, with photos
- CHAS, SafeContractor and ISO 9001

Questions from Swanbourne
Do you clean school ventilation in Swanbourne in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Swanbourne. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Can you get to a site in Swanbourne?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
What is 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 do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Swanbourne, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it 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.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand

What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
