AHU cleaning in Oakshott, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. Typical jobs include dust built up on fan impellers and condensate trays that won’t empty, across drain trays, dampers and louvres and heating and cooling coils.
Work in a small place like Oakshott starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

In-house cleaning or a specialist?
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, alongside our reports.

What affects the cost of AHU cleaning
Your quote is based on your site. We consider:
- Working hours and out-of-hours timing
- How big the system is
- A single visit or a regular plan
- Whether we need access equipment or extra panels
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we’ll talk you through it.
Helping us quote
When you contact us, these details help:
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
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 many jobs can be priced from that alone.
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Oakshott, let us know and we will plan around it.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in

We don’t publish a 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, call us on 0345 646 2711 or send us an email.
Related advice
Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Do you need AHU cleaning in Oakshott?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
The symptoms we are asked about most include:
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
For buildings in and around Oakshott, TR19® Air cleaning starts with an inspection.

Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
