Hire Van - Contents Insurance?

[CC07 PEU]

I'm hiring a van soon to move house and would like to insure its contents for one day.

The contents will not be covered under my home insurance policy so can anybody point me in the right direction as to who could offer this or what I should be looking for?

Nothing useful came up in Google - I tried the term "haulage insurance" but naturally all that came up was commercial insurance for big articulated lorries which isn't much use.

Try goods in transit insurance. Maybe not quite what you are looking for but
might work
