Our Expert Opinion on Coventry Building Society Junior Cash ISA

Coventry Building Society's Junior Cash ISA pays 3.75% and is a solid choice for parents, grandparents, or anyone wanting to build a tax-free pot for a child over the long term, with a low opening balance of just £1 and a generous annual allowance of up to £9,000. Transfers in from existing Junior ISAs are accepted, which is useful if you want to consolidate. The key constraint is that the money is completely locked away until the child turns 18, with the only exceptions being terminal illness or death, so this suits people who are genuinely comfortable committing those funds for the duration.
