Yes. You will need to cancel your card payment and set up a Direct Debit Instruction. To avoid a double payment, you should do this around three days before your next card payment is due. When logged in, go to ‘account’, and then ‘Cancel subscription’. Once cancelled, log back in and upgrade to Analyser by clicking on the yellow area in top right, hit 'Subscribe' and once on the payment page enter your Direct Debit Instructions.
