Our Expert Opinion on Moneybox Cash Lifetime ISA

The Moneybox Cash Lifetime ISA is aimed squarely at first-time buyers saving towards a property costing £450,000 or less, or anyone under 40 building a pot they will not touch until 60. The current rate is 4.45%, made up of a 2.80% base rate plus a 1.65% boost for 12 months, so I would note in my diary to reassess when that boost expires. The critical catch is the 25% government withdrawal penalty for any other purpose, which effectively claws back 6.25% of your own contributions, not just the bonus, so this money needs to stay put. If you want to compare, Plum's Lifetime ISA is currently sitting at 4.44%.
