Our Expert Opinion on Progressive Building Society 1 Year Fixed Rate ISA Bond

Jonny PeaseCo-Founder, DepositScout

Progressive Building Society's 1 Year Fixed Rate ISA Bond pays 4.50%, which sits near the market average for Cash ISAs but trails the category leader by 0.75%, where the best rate stands at 5.25%. It does beat inflation by 1.40% against August 2026 CPI of 3.1%, so your money grows in real terms. The catch is that no withdrawals are permitted without closing the account entirely. If you want a marginally better rate, Leek Building Society's 1 Year Fixed Rate Cash ISA offers 4.55%, though the maximum here is £20,000.
