Lock money away for five years, earn 5.17%

The government-backed saver NS&I raised its British Savings Bonds on 10 October. Its five-year bond now pays 5.17% a year, up from 4.85%, back above 5% after nearly three years. Two- and three-year bonds also pay over 5%. You must leave money locked until the end, from £500 to £1m per person per issue. Good deals can disappear fast.
