When you have downloaded an application form you need to fill in the following details:
- The name of your bank account;
- The sort code and account number of your bank account;
- The signature(s) needed to authorise payments from your account (e.g. if it's a joint account that needs two signatories make sure that both people sign)
You should then send it to your bank, ensuring that you allow as much time as they require to set up the Standing Order so that payment is made from your account on the First Payment Date.
