The emergency fund is the foundation of any financial plan — and in the UK, the choice of where to put it has rarely mattered more. After years of near-zero rates, UK savers can now earn 4-5% on easy-access savings accounts, making the cost of keeping money in a high-street current account significant.

💡 Premium Bonds: the UK's unique savings product
Premium Bonds from NS&I are backed by HM Treasury (100% safe) and instead of interest, you're entered into a monthly prize draw. The prize fund rate is equivalent to ~4.4% AER in 2026, and all prizes are tax-free. You can hold up to £50,000. Ideal if you're a higher-rate taxpayer and your Personal Savings Allowance is used up.
