Cabin Air Filter Replacement

I'm doing the 18,000 mile service. I've just taken off the glovebox to change the cabin air filter, but I can't see where it goes!

There are lots of useful guides online, but they all show LHD models (usually from the US) which are completely different to mine.

Can anyone offer any help for a UK-spec RHD model?

Thanks
