This means that Online Banking customers will now have the opportunity to opt out of receiving paper-based bank statements and receive them electronically instead, through Online Banking.

Separately, NatWest and RBS are also launching an 'Instant Access' service, which will allow customers to access basic Online Banking services more quickly than ever. Customers can sign up for the Instant Access service through NatWest or RBS's Online Banking homepage, or through a customer adviser at their local branch. All that is needed to access the service is a debit card number, account number, sort code and date of birth.

When customers have successfully completed the application process, they will immediately be able to access their account balance and recent transaction history. An Online Banking Welcome Pack will then be sent to the customer in the post, together with an upgrade code which will allow them to access the full Online Banking service and carry out more advanced functions, such as setting up standing orders and making third party money transfers.

David Gillespie, Director, Retail Markets said: "Our objective is to provide excellent service to our customers and offer them a choice in how they manage their money. We believe the introduction of paperless statements means customers can keep tabs on their expenditure and their account balance with the minimum effort, as well as cutting down on the amount of paper they receive through the post. What's more, with our Instant Access service, it couldn't be easier to get set up with Online Banking."
