Our Expert Opinion on Barclays Premier Triple Access 3-Year Flexible Cash ISA

Jonny PeaseCo-Founder, DepositScout

Barclays Premier Triple Access 3-Year Flexible Cash ISA pays 4.55%, which sits near the market average for cash ISAs and 0.57% behind the category leader at 5.12%, so it is not a standout rate. At 1.45% above CPI inflation of 3.1%, your money does at least grow in real terms. The three-withdrawal limit suits savers who want occasional access but can largely leave funds untouched, though early closure or a full transfer out triggers a 270-day interest penalty, which is the main catch here.
