Our Expert Opinion on Melton Building Society 100 Day Notice Cash ISA

Jan WatermannCo-Founder, DepositScout

Melton's 100 Day Notice Cash ISA pays 2.75%, which sits below the market average for cash ISAs and 2.37% behind the category leader at 5.12%. At current CPI of 3.1%, the rate is also 0.35% below inflation, so your money loses purchasing power in real terms. The 100-day notice period is the main catch, and the account does not accept ISA transfers in, which rules it out for anyone consolidating existing ISAs. Sidekick's Cash ISA at 3.23% or Moneybox's Open Access ISA at 3.80% are worth a look instead.
