So I've been thinking for a while now about organising some contents insurance - we are currently renting so don't need home insurance but if the house burnt down tomorrow, we've got a heck of a lot of stuff that would need replacing. I've found a couple of online calculators, but am kind of wondering anyone has a good way of figuring out the amount we should be covered for?

(also any suggestions on who does good contents only insurance wouldn't go astray )
