The gap between the best and worst savings rates available to ordinary savers has historically been significant. A major high-street bank might offer 0.1% on a standard savings account while an online bank or building society offers 4-5% on a comparable easy-access product. Over a year, on £10,000, that difference is £490 in interest income — for doing nothing other than choosing the right account.
Most people leave this money on the table because finding the better rate requires a small amount of active effort that they never quite get around to. This chapter eliminates the excuse.
Why your savings account probably pays too little
Banks pay interest on deposits because they use those deposits to fund lending. The interest rate they offer reflects the minimum required to attract and retain deposits — and for legacy high-street banks with large existing deposit bases, that minimum is low. Their customers are sticky: they keep accounts at the same bank for years or decades, and switching feels like effort.
Online banks and newer providers have smaller existing deposit bases and depend more on competitive rates to attract savers. As a result, they typically offer meaningfully higher rates.
The Bank of England (or equivalent central bank in other countries) sets a base interest rate that broadly determines the level of interest rates across the economy. When the base rate is low (as it was during 2010-2022), savings rates are low across the board, and the difference between providers is compressed. When the base rate rises (as it did sharply in 2022-2024), savings rates rise, and competitive providers offer substantially better rates than standard accounts.
The practical takeaway: it is always worth checking whether your savings rate is competitive, particularly after periods of rising interest rates.
Easy-access savings accounts
An easy-access savings account (also called an instant-access or flexible savings account) pays interest on a cash deposit while allowing withdrawals at any time without penalty.
This is the appropriate home for your emergency fund and any savings you may need within the next one to two years. The combination of competitive interest and immediate liquidity makes it the most versatile savings account type.
Rates on competitive easy-access accounts vary with the economic environment. In low-rate environments, even the best available rates may be 0.5-1.5%. In higher-rate environments, rates of 4-5% are achievable.
How to find the best rate: comparison sites (MoneySuperMarket, MoneySavingExpert, Savings Champion in the UK) aggregate current rates across providers and update regularly. The best rates often come from lesser-known online banks or building societies rather than the major high-street banks. These are typically fully protected by the Financial Services Compensation Scheme (FSCS) up to £85,000, so safety is not a reason to accept a lower rate.
Fixed-term deposits
A fixed-term deposit (also called a fixed-rate savings bond or time deposit) offers a guaranteed interest rate in exchange for locking up your money for a defined period — typically one month to five years.
Fixed-term rates are generally higher than easy-access rates because you are accepting reduced liquidity. In most cases, you cannot withdraw early without a penalty (forfeiting some or all of the interest earned, or in some products, a portion of principal). This makes term deposits suitable only for money you are confident you will not need during the term.
The decision between easy-access and fixed-term involves a trade-off: a higher guaranteed rate vs. access. If you have a fully-funded emergency fund in an easy-access account, additional savings intended for a medium-term goal (a house purchase in two years, for example) might be appropriately placed in a one or two-year fixed-term deposit.
The interest rate differential between fixed-term and easy-access products varies. Sometimes the premium for fixing is significant; sometimes it is small enough that the flexibility of easy-access is worth more than the additional interest.
Cash ISAs (UK)
In the UK, a Cash ISA (Individual Savings Account) is a savings account in which interest is earned tax-free. The annual allowance is £20,000 per person. Interest earned within the ISA is not subject to income tax regardless of the amount.
For basic-rate taxpayers, the Personal Savings Allowance (£1,000 per year) means many savers pay no tax on savings interest anyway. But for higher-rate taxpayers (£500 allowance) or those with larger savings balances, the ISA wrapper provides meaningful tax savings.
Cash ISAs come in easy-access and fixed-term versions with the same liquidity trade-offs as their non-ISA equivalents. Rates on Cash ISAs have historically been slightly lower than non-ISA equivalents, but the tax benefit often more than compensates.
Equivalent tax-advantaged savings vehicles exist in other countries under different names — the core principle (sheltering savings interest from income tax up to an annual limit) applies broadly.
Matching account type to purpose
The rule is simple: match the liquidity of the account to the timeline of the purpose.
Emergency fund → Easy-access savings account. Non-negotiable. The emergency fund must be accessible within 24 hours without penalty.
Short-term goals (1-2 years) → Easy-access account or short fixed-term deposit (3-6 months). Keep most accessible, but consider fixing a portion if the rate premium is meaningful.
Medium-term goals (2-5 years) → Fixed-term deposit or one-year rolling deposits. The money is unlikely to be needed suddenly, and the higher rate compounds over the period.
Long-term goals (5+ years) → Investment accounts rather than savings accounts. Over these time horizons, inflation risk outweighs market risk, and investment is almost certainly the better vehicle.
The key principle: every pound of savings should be working as hard as possible within the constraints set by its purpose. A competitive rate on a cash holding is not a substitute for investing, but it is meaningfully better than nothing.
