Our verdict

Online trading platform XTB offers a 4% AER flexible Cash ISA, placing it among the most competitive easy-access ISA rates on the market. XTB's headline-grabbing 6% initial 90-day bonus ended in April 2026, but may return.

Is XTB's Cash ISA Any Good?

The 4% rate is not guaranteed. XTB’s ISA terms confirm that interest is calculated daily and credited monthly at a variable rate that may change. This means the base rate could rise or fall depending on market conditions.

Is Your Money Held in a Bank or a Money Market Fund?

Another key consideration is where client money is held. XTB states that Cash ISA funds may be placed in segregated client money bank accounts or in one or more Qualifying Money Market Funds (QMMFs).

If funds are placed in a QMMF, they are not treated as bank deposits and do not benefit from traditional FSCS deposit protection in the same way as money held in a bank account. Instead, they fall under FCA client asset rules, with FSCS investment protection potentially applying in the event of firm insolvency, but not against investment losses.

Is XTB's Cash ISA worth it?

XTB's 4% is competitive but not the best rate we found. And funds may be held in a money market fund rather than a traditional bank account.

If you are putting money away in the long run, the stock market can offer much better returns, so investing in a stocks and shares ISA may make you more money.
