It would be really good if the header or title of each of the pages could include the account number of the relevant account (not just the customer number). My employer (who needs to review & match my trade confirmations) can’t accept the activity statement as evidence, as it does not include the exact account number anywhere.
For example, the ‘Day’s executed trades’ page for each of the Invest/Stocks ISA/CFD accounts should show the account number.
