Savings looks simple — put money in an account, earn interest — but the UK system layers on tax bands, protection limits, wrappers, and account types that meaningfully change your outcome. A saver with a maxed Cash ISA at a challenger bank at 4.8% and an unused Personal Savings Allowance keeps materially more of every pound than the same saver holding the same money in a high-street 1.2% account.

This hub is the map. Read left to right for the beginner path; jump straight to any section for the answer you need.

3. Account types (comparisons)

4. Calculators

5. Automation and apps
