ISA accounts with annual interest payments

[FreeLitres]

If you have an ISA account with an annual interest payment, what happens if you chose to transfer out? During the transfer, would the old provider calculate how much interest you have earned until that date, or would you lose that amount?

i.e. Interest payment due in April but you transfer funds to a new account in October, will they add your 6 months worth of interest that you haven't had?

Its not the interest payment period that matters but the T&Cs.

If its a one year fixed you could lose some/all the interest. If its easy access they should credit you with the interest you've earned up to the point of transfer. In summary read the T&Cs!
