Our Expert Opinion on Market Harborough BS Junior ISA

This account pays 3.40% and is a straightforward option for parents or guardians wanting a tax-efficient home for a child's savings, with a minimum of just £1 to open. It accepts transfers in from existing Junior ISAs, which is useful if you want to consolidate. The main catch is the one that applies to all Junior ISAs: the money is locked until the child turns 18, so this is genuinely long-term money. If you want a slightly higher rate, CMC Invest's Junior Cash ISA appears in our data at 3.56% and is worth a look.
