It is important that you use the online transfer process to transfer a Cash ISA. Your cash may lose its tax benefits if you try to transfer the money yourself. 

Why transfer a Cash ISA to a Stocks and Shares ISA?

Transferring to a stocks and shares ISA could be for you if you are comfortable putting your money into investments. 

With a Stocks and Shares ISA you have a choice of investing in funds, ETFs, shares and trusts. Each investment has the potential to outperform cash ISA savings rates, although this is not guaranteed.

Keeping too much money in cash means it can lose its value to inflation. Many people, who now feel the need to make their money grow faster or generate more income, are considering investing in a Stocks and Shares ISA, where they choose funds, investment trusts, ETFs and shares.

These investments have the potential to perform better than Cash ISAs but this is not guaranteed and you could lose some or all of your money.

What are the main benefits of a Stocks and Shares ISA?

  • You are in control of your investments

With a Stocks and Shares ISA, you have the freedom to choose how your money is invested. You can invest in a variety of stocks, shares, bonds, trusts and funds.

  • Potential to grow your money

With a Cash ISA, your money will only grow through interest. Through investment within a Stocks and Shares ISA, your money could grow above inflation, although there is also a risk of losing your money.

  • Tax benefits mean you keep all your profit

With a Stocks and Shares ISA, there is no tax on the gains. That means you can keep all the profit you make on up to £20,000 per year of investment. It also provides a number of other tax benefits. For more information, read our Stocks and Shares ISA explained page. 

Things to consider before transferring

  • Check for exit fees
    We do not charge fees to open or exit an ISA, but some providers do. Make sure you check for exit fees before transferring.
  • You can only pay in up to £20,000 per tax year
    Your annual ISA contribution limit still applies after you transfer. So if you’ve already paid in £20,000 with your previous provider, you can not contribute more until next tax year.
  • Investments can go down as well as up
    Transferring your cash into shares comes with risk as investments can go down in value. It is important not to risk money you cannot afford to lose.
  • It may be less suitable for short-term investment
    As share prices can go up or down, it is often recommended to keep your money invested for at least five years. If you are likely to need the money in the near future, a Stocks and Shares ISA may not be your most suitable option.

Are there any charges when transferring a Cash ISA to a Stocks and Shares ISA?

Transferring your ISA to interactive investor is free. However, your current provider may charge an exit fee. Make sure you check this before starting your transfer.

Our monthly service plan fee after your transfer is £9.99. Unlike many other providers who charge a percentage fee, our low fees don’t grow with your investments.

How long will the transfer take?

The transfer can take up to four weeks. We will update you regularly about the transfer’s progress. 

The transfer could take longer if there are delays from your current provider. Part of the transfer process is reliant on them and their timeframes can vary. Some Cash ISAs cannot be transferred electronically. If that is the case, we will send you a transfer authority form to print, sign and return to us.  

How can I track the progress of my transfer?

You will receive ‘transfer tracker’ emails at important milestones throughout your transfer.

However, you can request an update at any time. Simply log into your account and request an automated email from your investments page. 

When will I be able to invest the newly transferred funds?

You will be able to invest your transferred funds as soon as the transfer has been cleared. 

Can I transfer more cash into a Stocks and Shares ISA?

You can top up your Stocks and Shares ISA with either lump sum cash transfers or by setting up regular investing to pay in monthly. Remember that the maximum contribution in a single tax year is £20,000.
