Our Expert Opinion on UBL UK 4 Year Fixed Rate Cash ISA

Jonny PeaseCo-Founder, DepositScout

UBL UK's 4 Year Fixed Rate Cash ISA pays 3.91%, which sits below the market average for cash ISAs and 1.34% behind the current market leader at 5.25%. It does at least beat August 2026 CPI inflation by 0.81%, so your money keeps real value, but four years is a long commitment and withdrawals are not permitted without a penalty. The £2,000 minimum and £20,000 maximum cap are worth noting, and if you want a similar fixed ISA term, Coventry Building Society's Fixed Rate ISA 31.12.2028 currently offers 4.10%.
