Ian - I saw you left a comment at one of my answers from 2012. Before I answered, I checked the member's profile for location, and then offered a US-centric answer.
I don't know how the related post algorithm functions. I have my own issues with it, as I often click to find it sent me to a closed question. It's something that needs to be addressed there, and probably simpler to do so.
Trying to go back and change how questions are titled might impact the 'related' results, but a more direct approach might be better.
The other issue here, is that a question might be general as was Should I dip into an emergency fund to cover expenses for a rental property or only use it to make emergency repairs, improvements, etc.?, although my answer, to your point, was US. And as I noted, it was more to address something many small landlords miss, but didn't actually answer his question.
