No, recurring investments are not allowed in a MEXEM UK Stocks & Shares ISA account at the moment.
Please Note, recurring investments require fractional shares trading permissions. Fractional shares trading permissions are not allowed in a MEXEM UK Stocks & Shares ISA account as of yet.
HMRC regulations require MEXEM UK to remove the non-qualifying investments from the Stocks and Shares ISA account within 30 calendar days. MEXEM UK will transfer the non-qualifying investments to your linked General Investment Account to ensure we continue to operate your ISA account in accordance with HMRC regulations.
As confirmed in HMRC’s October 2024 newsletter, fractional shares are permitted in a Stocks and Shares ISA from 4 November 2024.
Following this regulatory update, MEXEM UK plans to offer fractional share trading within ISA accounts in the near future.
Please note: Until this feature is launched, only whole shares can be traded within a MEXEM ISA account.
To open a MEXEM UK Stocks and Shares ISA, you must use a GBP-denominated cash account.
A cash account means that:
1. All trades must be fully funded with available cash
2. You can only hold long positions (i.e. no short selling or margin trading)
This is in line with HMRC ISA regulations, which require that ISA accounts cannot use leverage or margin, and must be cash-funded.
Only GBP accounts are eligible for ISA use. Foreign currency accounts or margin accounts are not permitted within an ISA wrapper under UK tax rules.
You are able to see an overview of the contribution information for the current tax year by following the steps:
> Login to Client Portal
> Home Page
> Your Portfolio
> Deposit
> Choose Bank Transfer
You will then see the section Contribution information table, including Year to Date Contribution

- UK Government bonds (gilts)
- Corporate bonds

- Listed on a recognised stock exchange (in the UK or approved overseas exchanges)
- Transferable securities (i.e., tradable on the open market)
This includes most UK gilts and many corporate bonds, but not all bonds are eligible by default. Always check the listing status and denomination before investing.
The value of the investments held within your MEXEM UK Stocks and Shares ISA, along with any income they generate, may go down as well as up. This means you could receive less than your original investment.
Past Performance is not an indication of future performance.
Important Information
MEXEM UK Stocks and Shares ISA is offered on an execution only basis, MEXEM UK does not provide investment advice. If you are unsure about the suitability of an investment, you need to consult a suitably qualified financial advisor.

- Corporate securities
- Recognised UCITS funds (Undertakings for Collective Investment in Transferable Securities)
- Mutual funds
- Government and corporate bonds
- Depository Receipts, such as American Depository Receipts (ADRs) and American Depositary Shares (ADSs)
For the complete list of permitted ISA investments, please see the official HMRC ISA guidance.
Important Information
Stocks and Shares ISAs cannot hold non-qualifying investments. Only eligible assets may be included within your ISA account to maintain its tax-free status
Yes, your Mexem UK Stocks and Shares ISA must be funded every tax year. If you do not fund the account each tax year, then the MEXEM UK Stocks and Shares ISA will become invalid and can not receive additional deposits.
The account will remain open as long as the funds are kept in the account.
In line with HMRC regulations, you are eligible to open a Stocks and Shares ISA if you are a UK resident for tax purposes, and over the age of 18.
A National Insurance number (NINO) is a unique identifier used in the UK for administering the National Insurance or social security system. It is also used for some purposes in the UK tax system. The number is sometimes referred to as a NI Number or NINO.
This number is required when opening a Stocks and Shares ISA.
You are permitted to subscribe to one of each type of ISA per tax year, as long as your total contributions across all ISA types do not exceed the annual ISA allowance.
For Example:
An individual contributes £15,000 into a Stocks and Shares ISA, £3,000 to a Cash ISA, and £2,000 to a Lifetime ISA. Since only one of each ISA type was used, ths is allowed.
On the other hand, you cannot subscribe to more than one ISA of the same type in the same tax year.
For example:
If an individual contributes £10,000 into one Stocks and Shares ISA, £2,000 into a second Stocks and Shares ISA, and £8,000 into a Cash ISA, this is not allowed because they subscribed to two Stocks and Shares ISAs in the same tax year, even though the total is within the allowance.
You can open and hold multiple ISA accounts over time, but HMRC rules state that you can only subscribe to one of each ISA type per tax year.
If you have already subscribed to a Stocks & Shares ISA with a different provider in the current tax year, you cannot also subscribe to a MEXEM UK Stocks & Shares ISA until the new tax year begins.
If you exceed your annual ISA allowance, do not attempt to correct the issue by withdrawing the excess funds from your ISA (including your MEXEM UK Stocks and Shares ISA).
Instead, you should contact HMRC ISA helpline to report the oversubscription. HMRC will provide guidance on the appropriate next steps.
You can only open an MEXEM UK ISA account if you are a full tax resident of the United Kingdom with a National Insurance Number.
Please see HMRC website for full guidance.
When transferring an ISA to MEXEM UK, there are two main types of transfers:
In Specie (Position) Transfer:
This allows you to transfer your existing investments (positions) directly into your MEXEM UK ISA without selling them. This method avoids exiting the market and may help preserve your investment strategy during the transfer process.
Cash only Transfer:
In this case, your existing ISA provider will sell your investments and transfer the cash proceeds to your MEXEM UK ISA. You can then reinvest the funds once they arrive in your new account.
You will be able to see which transfer type we offer for your provider by logging into Client Portal and selecting Transfer & Pay then Transfer Existing ISA. After selecting your ISA provider, you will see the available transfer type.
MEXEM UK does not charge for transfers.
Note, the transferring ISA manager may charge you for transferring investments or cash proceeds to us.
You must inform MEXEM UK as soon as you stop being a UK resident. We will ask you to update your tax forms with the new country and mailing address, which will be updated upon review.
If you open an Individual Savings Account (ISA) in the UK then move abroad, you cannot put money into it after the tax year that you move (unless you're a Crown employee working overseas or their spouse or civil partner). However, you can keep your ISA open and you will still get UK tax relief on money and investments held in it.
Important information:
• You can transfer an ISA to another provider even if you are not resident in the UK.
• You can pay into your ISA again if you return and become a UK resident
• You can resume contributions if you return and become UK resident again.
This information is based on HMRC guidance on ISA eligibility and residency. You should consult HMRC or a qualified tax adviser if you are unsure about your personal circumstances.
To ensure that your ISA transfer is completed smoothly, your current ISA provider must be able to validate the account number you provide in the transfer request. If the account number is incorrect or invalid, the transfer request will be rejected by your provider.
MEXEM strongly recommends that you check your most recent brokerage statement to confirm the exact account number before submitting your transfer request.
We may provide a list of common account number formats used by certain providers, but please note this is for reference only. You should always verify the correct format directly with your current ISA provider if you have any doubts.
An ISA transfer typically takes anywhere from a few business days up to 30 calendar days, depending on the type of assets being transferred and the efficiency of the institutions involved.
Please Note
The exact timeline largely depends on your current (delivering) ISA provider. Your transfer will not progress until both the delivering and receiving institutions are in contact. In most cases, the receiving provider (MEXEM UK) initiates communication once the ISA account is open and ready to accept the transfer of cash or securities.
We recommend monitoring your Client Portal for status updates and contacting your existing provider if delays occur.
An ISA transfer request can be rejected for several common reasons:
- Mismatch in account format entered.
- Mismatch in personal account information on record (Name, Address (postal code), Date of Birth and NINO).
- Your existing ISA provider requires additional information or documents.
- Some ISA provider may require you to send documents by post to complete the transfer.
- Valuation or clearing discrepancies during the transfer process
To avoid delays or rejection:
- Ensure that all personal details and your account number are entered exactly as they appear on your latest statement.
- We strongly recommend checking with your current ISA provider to understand their specific transfer procedures and any documentation requirements.
When transferring your ISA from or to another provider, certain personal details must match exactly across both accounts.
- Transfer requests may be rejected if there is a discrepancy in any of the following:
- Full Name
- Residential Address (including postcode)
- Date of Birth
- National Insurance Number (NINO)
To prevent delays or rejections:
- Please ensure your account information is up to date and identical with both MEXEM UK and your existing ISA provider. If there are any mismatches, update the relevant records before submitting your transfer request.
To transfer your Stocks and Shares ISA Account from your current ISA provider to MEXEM please log in to Client Portal and follow the steps:
- Navigate to Transfer & Pay
- Select Transfer Existing ISA
- Follow the on screen steps:
- Enter your current ISA Provider Account ID
- Select from the dropdown list your provider Name
Depending on your Stock and Shares ISA account provider, MEXEM may offer "In Species/Position Transfer" and "Cash only Transfers".
After submitting the request MEXEM will contact your current ISA Manager to initiate the transfer of your account.
Important Information:
If MEXEM does not support all your investments held at your existing ISA Manager, you can have two options:
- Sell the unsupported investments yourself before initiating the transfer (any cash proceeds of such liquidation will be transferred to your MEXEM ISA)
- Instruct MEXEM (as part of your transfer instructions via Client Portal) to liquidate those investments.
Your current Stocks and Shares ISA account provider must validate the account number provided on the request.
All personal details must match exactly (Name, Address (postal code), Date of Birth and NINO) across both providers.
How Long Does it Take:
ISA transfers typically take a few business days, up to 30 calendar days, depending on your current provider.
Please note that you can track the progress of your ISA transfer via Transfer & Pay followed by Transaction Status & History.
Fees:
MEXEM does not charge a fee for incoming ISA transfers
Your current ISA provider may charge exit or transfer fees - please check with them directly.
Additional Information:
- Only full ISA transfers are supported.
- MEXEM UK may not support transfers from all ISA providers.
- You will see the list of supported providers when you initiate the transfer in Client Portal.
To transfer your MEXEM Stocks and Shares ISA to another ISA provider, the request must be initiated with your new (receiving) ISA provider. Transfer Process Contact the new ISA provider you wish to transfer your account to. Ask them to send a client-signed request form to the following address [email protected]
Your new ISA provider may have their own documentation or procedures, so it is important to follow their instructions carefully.
Reminder:
Transfers between ISA providers must follow HMRC rules. Ensure you do not withdraw funds manually to move your ISA, doing so will cause you to lose the ISA tax benefits.
A Junior ISA (JISA) is a tax-free savings and investment account designed to help you build a secure financial future for your child. Any money you invest grows free from Income Tax and Capital Gains Tax, making it one of the most efficient ways to save for their future.
There are two types of Junior ISAs available in the UK:
Junior Cash ISA – earns tax-free interest.
Junior Stocks & Shares ISA – lets you invest in a wide range of qualifying investments such as shares, ETFs, funds, and bonds.
At MEXEM, we will soon offer a Junior Stocks & Shares ISA that gives you access to 150+ global markets, 33 countries, and 23 currencies, all through our powerful trading platforms.
Parent or legal guardian:
Opens the account and acts as the registered contact.
Ownership:
All contributions belong to the child.
Access:
Funds remain locked until the child turns 18, at which point the Junior ISA automatically converts into an adult Stocks & Shares ISA.
For the 2025/26 tax year, the Junior ISA annual allowance is £9,000.
This limit applies across all Junior ISAs your child may hold, including both cash and stocks & shares accounts.
Yes, you will need a National Insurance Number (NINO) to open an ISA account.
Please Note:
If not already listed then you need to enter the National Insurance Number in the Tax ID section of your profile to open a linked ISA account.

Click the Person icon on the top right of the screen
> Settings
> Account Settings followed by Account Profile
> Profile Followed by the Pencil Icon to Edit your Profile information
> In the Tax Residency section you may edit the information or remove Tax Residency and add another Tax Residency
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.
