Our Expert Opinion on OakNorth Bank Easy Access Cash ISA

Jan WatermannCo-Founder, DepositScout

OakNorth Bank's Easy Access Cash ISA pays 2.75%, which is below the market average for Cash ISAs and sits 2.37% behind the category leader at 5.12%, so I would not call this a standout rate. It also falls 0.35% below CPI inflation of 3.1% (Aug 2026), meaning your money is losing real purchasing power. The £1 minimum deposit is genuinely low and transfers in are accepted, which suits someone consolidating old ISAs, but I would at least compare the Moneybox Open Access Cash ISA at 3.80% before committing here.
