Our Expert Opinion on AIB (NI) Fixed Rate Saver – 24 Month

Jan WatermannCo-Founder, DepositScout

AIB (NI)'s Fixed Rate Saver pays 4.00% over 24 months, which sits below the market average for fixed-rate accounts and 1.37% behind the category leader at 5.37%. It does beat August 2026 CPI of 3.1% by 0.90%, so your money grows in real terms, which is something. The genuine catch is total illiquidity: no access until maturity. If you want a two-year fix at a better rate, OakNorth Bank and Shawbrook both offer 4.85% over the same term.
