“Best buy” savings tables change almost daily, and the best account for one person can be wrong for another. Instead of quoting rates that will soon be stale, this guide sets out a method you can apply any time to find a genuinely good home for your savings.
1. Decide what the money is for
Start with purpose and timing. An emergency fund needs instant access. A house deposit you will need in two years might suit a fixed-rate bond. Money for a holiday next summer might fit a notice account or regular saver. Splitting savings into “pots” by purpose makes the choice much easier.
2. Compare on AER – but read the conditions
The Annual Equivalent Rate (AER) lets you compare accounts that pay interest at different frequencies. Then check what is behind the number:
- Bonus rates that disappear after 12 months.
- Withdrawal limits – some “easy access” accounts reduce the rate if you withdraw more than a few times a year.
- Minimum or maximum balances.
- Linked accounts – some top rates require you to hold a current account with the provider.
3. Understand the account types
Easy access accounts offer flexibility; notice accounts and fixed-rate bonds usually pay more in exchange for less access. Regular savers can pay attractive rates but on limited monthly deposits, so the interest in pounds may be modest. Cash ISAs shelter interest from tax.
4. Think about tax
The Personal Savings Allowance lets basic-rate taxpayers earn £1,000 of interest tax-free and higher-rate taxpayers £500 (GOV.UK). If your interest could exceed your allowance, a cash ISA can be better even at a slightly lower rate. The annual ISA allowance is £20,000 across all ISAs.
5. Check protection
Eligible deposits are protected by the FSCS up to a limit per person per authorised institution. Several well-known brands share a banking licence, so check before splitting large sums. Use the FSCS website to confirm.
6. Run the numbers
Use our Savings Interest Calculator to see what a rate difference actually means in pounds. Moving £10,000 from an account paying 1% to one paying 4% would mean around £300 more interest in a year at constant rates – often worth twenty minutes of admin.
7. Review regularly
Set a reminder every six months to check your rates. Providers often launch competitive rates for new customers and let existing accounts drift down. Switching is usually quick, but check for notice periods or penalties first.
CalcMondo does not recommend specific providers. Check current terms directly with the provider before opening an account.
