This Morning: Martin Lewis gives advice about switching banks
Money saving expert Martin Lewis has turned a spotlight on a banking war as household giants hand out large cash sums to tempt customers to switch.
He said four banks - Santander, First Direct, Lloyds and TSB - are now offering handouts of £175 each to get customers to switch to them with others expected to follow suit.
Separately, Nationwide is offering £200 to some existing customers if they switch accounts held with other financial institutions to the building society, for a total of £900 currently available to customers willing to bank hop.
Martin Lewis said the situation has allowed some savvy consumers to cash in to the tune of thousands of pounds by becoming super switchers - constantly swapping between banks in order to receive a payment.
And some are even setting up so-called 'burner accounts' that they can use as a tool to switch between banks in order to claim a windfall.
It said these super switchers also use a second tactic, known as stoozing, which takes advantage of an introductory interest-free period offered by a credit-card company to borrow money for investment elsewhere.
One follower of the website, identified as Simon, said: "Over 12 months my wife and I undertook 10 bank switches, managed our spending through stoozing, and made sure we used cashback sites for purchases.
"Through these methods, we managed to amass £3,000 which we used to pay for a seven-day family holiday in Rome, which we loved.
"We managed this all through the help of MSE. Thank you MSE for paying for our holiday - we'd not have been able to go to Rome without your help."
