Our Expert Opinion on Paragon Bank 14 Month Fixed Rate Cash ISA

Jonny PeaseCo-Founder, DepositScout

Paragon Bank's 14 Month Fixed Rate Cash ISA pays 4.15%, which beats August 2026 CPI of 3.1% by 1.05%, so at least your money grows in real terms. That said, 4.15% sits below the cash ISA market average, and the best rate in the category is 5.12%, leaving this account 0.97% behind the leader. You need at least £500 to open it, and the money is locked away for 14 months, so this suits someone who wants ISA wrapper protection and can commit to that term, but I would still check Kent Reliance's Easy Access Cash ISA at 4.24% if you want flexibility.
