Our Expert Opinion on Melton Building Society Fixed Rate ISA

Jonny PeaseCo-Founder, DepositScout

Melton Building Society's Fixed Rate ISA pays 4.5% until maturity on 24 September 2031, which does beat inflation by 1.40% against a CPI of 3.1%, but it sits below the cash ISA market average and 0.62% behind the market leader at 5.12%. The real catch here is the complete lack of access until maturity, so you are committing your money for several years with no flexibility. For a similar or slightly better rate with presumably more flexibility, Chip's Smart Cash ISA is currently paying 4.56%. You need at least £1,000 to open, and transfers in are accepted.
