The NHS only use Microsoft Office 1997 - 2003, so you are going to lose all the refinements of PPTX 2007.
I think the only solution for you is to convert your PPTX to Video; save as WMV and then your colleages can have a copy and you will be able to upload it to your website. This way you won't lose any animation, builds, transitions, etc.
I use PPTX to YouTube/Video and it's excellent. In the past, I have uploaded to YouTube and embedded videos on my website.
