Our Expert Opinion on Nationwide 2 Year Fixed Rate Cash ISA

Jan WatermannCo-Founder, DepositScout

Nationwide's 2 Year Fixed Rate Cash ISA pays 4.55%, which sits near the market average for cash ISAs and is 0.57% behind the category leader at 5.12%, so it is not a standout rate. That said, 4.55% does beat August 2026 CPI of 3.1% by 1.45%, meaning your money grows in real terms. The account accepts transfers in and opens with just £1, though the ISA allowance cap of £20,000 applies and the main catch is that you cannot access your money at all until the two-year term ends. If the rate matters more than the Nationwide name, Moneybox's Cash ISA currently offers 4.58%.
