Our Expert Opinion on Aldermore 2 Year Fixed Rate Cash ISA

Jonny PeaseCo-Founder, DepositScout

Aldermore's 2 Year Fixed Rate Cash ISA pays 5.01%, which sits above the cash ISA market average but 0.24% behind the category leader at 5.25%, so I would still check alternatives like Shawbrook's 2 Year Fixed Rate Cash ISA at 5.06% before committing. The rate does beat CPI inflation of 3.1% by 1.91 percentage points, which is a decent real return for cautious savers. The main catch is the two-year lock-in; early access is allowed but costs you 180 days of interest, and deposits are capped at £20,000.
