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.

XTB is the worst company I have ever dealt with.

Greg W ·

AVOID XTB - they are dishonest and poorly managed. I currently have 2 cases pending against them. The first is their complete refusal to comply with GDPR and the second for refusing to transfer my French PEA account to another bank. Both of these incidents are highly illegal and the French authorities are involved. The UK and Polish head offices are aware of the situation and doing nothing to help. AVOID XTB at all costs.

Spiros ·

I find the platform easy to use and it has everything you need. I have created my own Investment Plan and I invest in stocks. Not much of a risk taker myself. I have spoken to the account managers a few times too. They are super helpful and there to answer any questions you have. The platform has gotten better over the years and has definitely improved. Overall it offers everything I need.
