Some people just don't believe this , but when you think about it you could go for months and say you had just got there if something went wrong , I went for 5 weeks last year with no return booked insured by staysure which cost over £100 but one day got to reading the small print and found it, when I got back I rang them and it was confirmed , I had been there all that time with no insurance, but they didn't offer me a refundAnd make sure it is still valid if you have not got a return ticket booked, most aren't!
This is a copy from page twelve on their policy
Each trip must begin and end in the United Kingdom and a return ticket must have been booked prior to departure.
