Our Expert Opinion on Market Harborough BS 100 Day Notice ISA

Jan WatermannCo-Founder, DepositScout

This account pays 2.7% on a 100-day notice Cash ISA with a £5,000 minimum, and it accepts transfers in, which suits someone consolidating older ISAs into one place. That said, the rate sits below the market average for Cash ISAs and is 2.55% behind the category leader at 5.25%, so there are meaningfully better notice and easy-access ISA options available. At 2.7% it also falls 0.40% below current CPI inflation of 3.1%, meaning your money is losing purchasing power in real terms. I would only consider this if you have a specific reason to bank with Market Harborough BS.
