Nationwide has extended its popular ‘refer a friend’ scheme to allow anyone with one of its mortgages or savings accounts to earn up to £500 a year – though it’s added more hoops to jump through to get the cash.

Previously the scheme was only open to current account holders, but now almost anyone with a Nationwide mortgage or savings account can net a possible £500 a year pre-tax, by referring five people to switch to a current account.
