Savers looking to give their finances a boost could pocket £200 simply by switching banks. Two major high street lenders are offering cash incentives to tempt new customers this month. Banks frequently roll out switching offers as a means of expanding their customer base, though these are typically one-off deals exclusively available to brand-new account holders. According to the experts at Money Saving Expert (MSE), two banks are offering up £200 for free if you make the switch by 28th May.
