Our Expert Opinion on NS&I Investment Account

Jan WatermannCo-Founder, DepositScout

The NS&I Investment Account pays 2.05%, which is 2.95% below the easy access market leader at 5.00% and sits below the market average, so the rate is hard to justify on yield alone. It also falls 1.05% short of CPI inflation at 3.1%, meaning your money is losing real purchasing power. The bigger practical catch is that access is postal only, which rules out anyone who wants quick or online withdrawals. If you want easy access with a better return, Tandem Bank's Instant Access Saver is paying 3.40%.
