FAQ

Get the answers you need to start building your portfolio today.

Is trading really free for US and EU shares in the ISA?

Yes. MEXEM UK does not charge a trading commission for US and EU shares in an ISA. When investing in overseas shares, FX conversion applies at 0.25%, with total FX costs up to 0.35% including third-party fees.

Can I invest in US and European shares in a Stocks & Shares ISA?

Yes. With MEXEM UK, you can invest in UK, US and European shares within your Stocks & Shares ISA. The account is GBP-based, and FX is applied automatically when you trade overseas securities.

Can I transfer my existing Stocks & Shares ISA to MEXEM?

Yes. You can transfer an existing Stocks & Shares ISA to MEXEM without losing its tax-efficient status. ISA transfers must be completed using the official transfer process and should not be withdrawn manually.

Are there other fees applied, like for the maintenance of an account?

There are no fees to open, maintain, or close the account.

Are there fees for transferring an ISA?

MEXEM does not charge a fee to receive ISA transfers. Your existing provider may charge exit or transfer fees, which are set by them and not by MEXEM.

Are my ISA and General Investment Account kept separate?

Yes. Your ISA and General Investment Account are legally separate accounts with different tax treatment. Investments are not mixed, and ISA rules always apply to assets held within the ISA.

Is a Stocks & Shares ISA suitable for beginners?

A Stocks & Shares ISA can be suitable for beginners with a long-term investment horizon, but market risk applies. MEXEM UKprovides professional tools and transparent pricing, making it suitable for investors who want to grow into more advanced investing over time.

Is my ISA account with MEXEM UK a flexible ISA?

No, the only ISA account type that Mexem offers is a non flexible Stocks and Shares ISA account. That means you can take money out, but it will count towards your annual ISA allowance if you pay it back in the same tax year.

What is a Stocks & Shares ISA?

A Stocks & Shares ISA is a UK tax-efficient investment account that allows you to invest in shares and other eligible investments. Any capital gains and investment income earned inside the ISA are free from UK Capital Gains Tax and Income Tax, subject to HMRC rules and annual allowance limits.

What fees do you pay with a MEXEM Stocks & Shares ISA?

MEXEM charges no platform, custody or inactivity fees.
 UK shares cost £2 per trade.
US and EU shares are commission-free.
FX applies at 0.25%, with total FX costs up to 0.35% including third-party fees.

Are my funds protected with MEXEM?

MEXEM does not hold client funds or securities. Client assets are held with Interactive Brokers in segregated accounts. The level and type of investor protection available to you depend on the Interactive Brokers group entity with which your account is opened (e.g. IBKR LLC, IBKR UK, IBKR Ireland, IBKR Central Europe), and your country of residence. Investor protection schemes, coverage limits, and eligibility conditions vary by jurisdiction.

Is there insurance for my trading funds?

Where applicable, client assets may be protected under statutory investor compensation schemes in the event of the insolvency of the custodian. Coverage depends on the Interactive Brokers entity with which the account is opened and the applicable jurisdiction. These schemes do not protect against trading losses or market risk. Additional insurance coverage, if any, is determined by the relevant Interactive Brokers entity.

Past performance is not a reliable indicator of future results.  The value of investments, and the income derived from them, can fall as well as rise.  You may get back less than you have invested.
