Our Expert Opinion on Halifax ISA Bonus Saver

Jonny PeaseCo-Founder, DepositScout

The Halifax ISA Bonus Saver pays 3% but only if you make two or fewer withdrawals in a 12-month account year; a third withdrawal drops the rate to 0.65% from that month, which is the real sting here. At 3%, it sits below the Cash ISA market average and 2.12% behind the category leader at 5.12%, and it barely keeps pace with inflation at 0.10% below August 2026 CPI of 3.1%. This suits disciplined savers who rarely dip in and value Halifax's instant access, but if you think you might withdraw more freely, Moneybox's Open Access Cash ISA offers 3.80% without that constraint.
