Our Expert Opinion on Barclays Premier Triple Access 1-Year Flexible Cash ISA

Jonny PeaseCo-Founder, DepositScout

This account 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 is best suited to existing Barclays Premier customers who want a familiar home for their ISA with limited flexibility, but the withdrawal rule is a genuine catch: each of your three free withdrawals is capped at 10% of your balance at the time, so you cannot take out a larger lump sum in one go.
