Full Verdict

For savvy savers who want certainty, Cynergy Bank's Fixed Rate Cash ISAs are often market leaders. By locking your money away for 1 year, you guarantee a 4.15% return, regardless of what the Bank of England does with base rates.

While you lose improved access compared to variable accounts, the peace of mind of a fixed return is valuable. The online banking platform is functional and straightforward.

Tax-Free Savings? Yes Please.

What is a Cash ISA?

A Cash ISA is just a savings account where the taxman can't touch the interest. You can put in up to £20,000 each tax year. It's the smartest place to keep your emergency fund or short-term savings.

Fixed vs Variable: "Fixed" means you lock your money away for a year (or more) for a guaranteed rate. "Variable" (or Easy Access) means the rate can change, but you can get your money out whenever you want.

Inflation Risk

Cash ISAs are generally low risk and covered by the FSCS (up to £85k). The main risk is inflation. If the interest rate is lower than inflation, the real buying power of your money will go down over time.
