6. Martin Lewis-Style Strategy for Over-60s
1. Split for flexibility and growth
- Allocate a portion of your ISA allowance to easy-access accounts (e.g., Plum at ~4.66%).
- Place remainder in fixed-rate ISAs for 1–3 years to lock in returns.
2. Use Notice ISAs for strategic balance
- Take advantage of higher rates than fixed accounts without complete sacrifice of access.
3. Prefer flexible ISAs where possible
- Some providers (like Plum, Tembo, Moneybox) allow you to withdraw and replace within the tax year without impacting allowance—a powerful feature in volatile markets.
4. Avoid teaser traps
- Watch out for introductory bonus rates—always verify the ongoing AER and post-bonus trajectory.
5. Transfer, don’t withdraw
- Transfer existing ISAs to better-paying accounts while preserving the tax wrapper—avoid withdrawing and losing allowance protection.
6. Act before rate reductions bite
- With some banks lowering rates imminently, proactive switching matters.
7. Spread across institutions
- Use multiple providers (within FSCS limits) to diversify risk and maximize opportunities.
7. Sample Portfolio for Over-60 Savers (Using £20,000 ISA Allowance)
