Explain the ISA Types Available in the UK

You have heard the word ISA, you know it is meant to save you tax, and that is roughly where the understanding stops. This explains each main type in plain English: cash ISA, stocks and shares, the lifetime version, the allowance rules, and who each one actually suits. No provider recommended. For first-time savers picking their starting point.

3. Lifetime ISA (LISA): the 25% government bonus, the home-purchase and retirement rules, and the withdrawal penalty trap
4. Innovative Finance ISA: what peer-to-peer lending is, the risks, why it is riskier than a cash ISA
5. Junior ISA: how it works for parents saving for children
