Martin Lewis' Money Saving Expert website has explained how people can get around £400 for free by using an "easy trick". One way you can earn extra cash is to claim £175 by switching to the Santander 123 Lite account.
It costs £2 a month but you can earn up to £15 a month cashback, which cancels out this fee. You can earn cashback, each of which is capped at £5 a month, in three different ways, the Mirror reports.
Council tax, mobile and home phone bills, broadband and paid-for TV packages and Santander mortgage payments are included in the first tier. Meanwhile, the second tier is 2% back on gas and electricity bills, and Santander life and home insurance.
