Our Expert Opinion on Halifax ISA Saver Fixed 1 Year

Jan WatermannCo-Founder, DepositScout

Halifax's ISA Saver Fixed 1 Year pays 4.00%, which is below the market average for cash ISAs and 1.12% behind the category leader at 5.12%. The rate does beat August 2026 CPI of 3.1% by 0.90%, so your money grows in real terms, but the gap to better deals is hard to ignore. The main catch is no access until maturity, so only commit money you can lock away for a year. Spring's Easy Cash ISA offers 4.01% if you want a marginally better flexible alternative.
