Our Expert Opinion on Teachers Building Society Single Access Cash ISA for Everyone

Jan WatermannCo-Founder, DepositScout

Teachers Building Society's Single Access Cash ISA pays 4.20%, which beats August 2026 CPI of 3.1% by 1.10%, but sits 1.05% below the best Cash ISA on the market at 5.25% and is below the market average overall. The name says it all: you get one penalty-free withdrawal per calendar year, and a second dip drops your rate to 1.25% for the rest of that year. If you want similar flexibility with a slightly better rate, Kent Reliance's Easy Access Cash ISA offers 4.24%.
