Our Expert Opinion on Tandem Bank 2 Year Fixed Saver

Jan WatermannCo-Founder, DepositScout

Tandem Bank's 2 Year Fixed Saver pays 5.00%, which sits near the market average for fixed-rate savings and 0.35% behind the current market leader at 5.35%. That said, it does beat inflation by 1.90 percentage points against CPI of 3.1% as of Aug 2026, so your money is growing in real terms. The main catch is the complete lack of access until maturity, so only commit money you are certain you will not need for two years. If you want a slightly better two-year rate, Atom Bank's 2 Year Fixed Saver is listed at 5.10%.
