Worth knowing
- Your money is locked away until the fixed term ends.

GB Bank's 6 month fixed rate bond pays 4.62%, which does beat August 2026 CPI of 3.1% by 1.52%, so your money at least grows in real terms over the short term.
That said, the rate sits below the market average across fixed rate bonds, and the market leader in that category is paying 5.37%, putting this 0.75% behind. You can deposit between £1,000 and £100,000, but there is no access until maturity, so this suits someone parking a defined sum they genuinely will not need for six months.
Zopa's Fixed Term Pot at 4.60% is worth a look as a close alternative.
