AHU cleaning in Twelve Oaks
We clean air handling units for buildings in Twelve Oaks and across East Sussex, working to TR19® Air, 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 internal panels, supply and extract fans and dampers and louvres, and common reasons people get in touch are units needing a clean before a new tenant or handover and dirty coils holding back the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Change filters on schedule and log each change
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What affects the quote in Twelve Oaks
The diagnosis comes before the price. We look at:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- The condition of the system
- The number of sites or systems
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What we need to know
To help us quote quickly, please include:
- The site address and the type of premises
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
When it’s something else
Some problems need a different service or another trade:
- Mechanical faults with motors, belts or bearings
- Building management system faults
- Coils that are corroded or leaking and need replacing
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think before booking.
Parts of the system we cover

The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Twelve Oaks.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know about permits to work or site inductions
- Let us know about parking and loading
- Move anything stored near the system
