Our Expert Opinion on Nationwide 5 Year Fixed Rate Cash ISA

Jonny PeaseCo-Founder, DepositScout

Nationwide's 5 Year Fixed Rate Cash ISA pays 4.70%, which sits near the market average for cash ISAs, putting it 0.42% behind the category leader at 5.12%. At 1.60% above August 2026 CPI of 3.1%, your money does grow in real terms, which matters over five years. The obvious catch is that access is completely locked until maturity, so this suits savers who are confident they won't need the money. The £20,000 cap means it fits neatly within the annual ISA allowance.
