How Prizes Work

Your bonds don’t earn interest. Instead:

  2. Random draws allocate prizes to winning bond numbers
  3. Each bond has equal chance of winning

Common Questions

Are Premium Bonds Worth It for Small Amounts?

£25-1,000: Likely to win nothing for months. Not worth it for returns — only for fun.

£1,000-5,000: Might win occasionally. Marginally worth considering.

£5,000+: Will win something most months. More worthwhile.

£50,000: Maximum value extraction, regular wins likely.

Can I Hold More Than £50,000?

No. The maximum individual holding is £50,000. Couples can each hold £50,000 = £100,000 household total.

What Happens to Unclaimed Prizes?

NS&I holds unclaimed prizes for 16 months, then they return to the prize fund. Check regularly or set up prize auto-reinvestment.

Is My Money Safe?

Your Decision Framework

Choose Premium Bonds If:

  • Already maxed ISA allowance
  • Already using full PSA on savings
  • Enjoy the monthly draw anticipation

Choose Savings Account If:

  • Non-taxpayer or basic rate
  • PSA not fully used
  • Want guaranteed, predictable returns
  • Need instant access
  • Prefer certainty over chance
  • Have smaller amounts to save

Use Both If:

  • Have substantial savings
