Our Expert Opinion on Scottish Building Society Cash ISA

Jonny PeaseCo-Founder, DepositScout

Scottish Building Society's Cash ISA pays 2.35%, which is below the market average for Cash ISAs and sits 2.90% behind the category leader at 5.25%, so this is a hard account to recommend on rate alone. It also falls 0.75% short of CPI inflation at 3.1%, meaning your money is losing purchasing power in real terms. The £100 minimum is low and instant access is useful, but the £20,000 cap limits you to one ISA allowance. If you want instant access within a similar range, Monzo's Instant Access Cash ISA pays 2.75%.
