AHU Cleaning in Oxley Green
AHU cleaning for businesses, landlords and public buildings in Oxley Green. CHAS, SafeContractor and ISO 9001, and fully insured.

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
About our AHU cleaning in Oxley Green
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 pictures, so you can see the unit’s condition for yourself. Typical jobs include air handling units with blocked filters and plant that has been serviced but not cleaned, across dampers and louvres, drain trays and internal panels.
For a building in or near Oxley Green, access is agreed in advance and the visit is planned around the journey.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Do you need AHU cleaning in Oxley Green?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Oxley Green, that’s air they breathe for hours at a time.
Common reasons sites call us are:
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
For schools like Thurstable School, the holidays are the usual time to inspect and clean ventilation.
Comparing quotes

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Oxley Green.
- 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.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site

Advice
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think.
What the work covers

Your questions about AHU cleaning in Oxley Green
Do you work in villages like Oxley Green?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in Oxley Green outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, typically ready within one working day.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
