Our Expert Opinion on Vernon Building Society 30-Day Notice Cash ISA

Jan WatermannCo-Founder, DepositScout

Vernon Building Society's 30-Day Notice Cash ISA pays 2.85%, which is below the market average for Cash ISAs and 2.27% behind the category leader at 5.12%. The rate also sits 0.25% below CPI inflation of 3.1% (Aug 2026), meaning your money is losing purchasing power in real terms. The 30-day notice period is the main practical catch, so this suits savers who want ISA tax wrapping and can plan withdrawals in advance, but alternatives such as the Moneybox Open Access Cash ISA at 3.80% or Sidekick Cash ISA at 3.23% look more compelling on rate alone.
