If you are looking to withdraw from your ISA and not close the account, you are able to withdraw as often as you like from both current and previous tax years' subscriptions of your ISA but you will lose the tax free status on the funds you withdraw. Your options of withdrawing will depend on the funds you're invested in but most withdrawal requests can be made via My Account. There may be some funds where you need to contact us us to allow us to process your request, detail of how to contact us are found here. There’s a minimum amount you must take out and a minimum amount that you must leave in. This is usually £100 for both.
