Can you insure a laptop if you're already traveling?

Can anyone recommend an insurance company that will specifically insure a laptop for a few months or more for a UK citizen whilst already abroad for over a year and without a return date?

I used to insure we Jelf under similar circumstances.

They were fairly reasonable. However - I was fixed in a long-term ish rental. You would need to ask if they have anything suitable if you are permanently roaming.

Would be interested what you find out actually.
