Do I get paid for taking time off work for my grans funeral?

You might or you might not... you have to ask your human resources dept at the place you work to find out.

My company included parents, grandparents, siblings, children, aunts, uncles and in laws in bereavement leave coverage. It depends on their policy.

A company does not have to provide bereavement leave at all. But most do subject to a specific policy. So we can't answer you, you need to check your employee handbook or HR dept.
