NS&I Premium Bonds vs Standard savings account

Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.

Quick answer: Premium Bonds are a UK government-backed lottery savings product where instead of interest, your money earns entries into monthly prize draws. No risk to capital. Prize fund rate: 3.80% (from the July 2026 draw; odds 22,000 to 1 per £1 bond) but this is the total paid out, not what any individual earns. Most savers earn less than 3.80%; some earn more (including tax-free prizes). Competitive savings accounts can pay more and give more predictable returns, so compare current rates.

Who should use Premium Bonds?

Best for: additional-rate taxpayers (45%) who've used their ISA allowance and Personal Savings Allowance — tax-free prizes are genuinely valuable. Worst for: basic-rate taxpayers with under £20,000 who can use an ISA instead (tax-free interest with guaranteed returns).
