Chancellor Rachel Reeves announced a cut to the Cash ISA allowance from £20,000 to £12,000 from April 2027, to drive more investment into the UK economy. This is spiking an interest in Stocks and Shares ISAs, but what should you consider before opening an account?
What is a Stocks and Shares ISA?
Individual Savings Accounts (ISAs) let you grow your money free from tax. They’re open to UK residents aged 18 or over (you must be under 40 to open a Lifetime ISA). There are several different types of ISAs, including Cash ISAs, Junior ISAs and Stocks and Shares ISAs.
As the name suggests, a Stocks and Shares ISA is an investment account, giving you the potential to get higher returns than a Cash ISA over time.
Things to consider before getting a Stocks and Shares ISA
Like any investment project, you risk losing rather than growing your money with a Stocks and Shares ISA. For this reason, it should be opened with a view to supporting mid- or long-term goals rather than funding immediate needs, and you should only put in what you could afford to lose.
Analyse your personal finances to get an accurate view of your current expenses and short-term savings demands, like sustaining an emergency fund versus your earnings. This will give you an idea of how much you’re able to invest safely. You may wish to split your savings across different accounts, keeping some funds in a standard savings account for security.
Before opening a Stocks and Shares ISA, explore the different options available. Consider potential provider costs such as platform fees, their customer satisfaction ratings, trading fees and fund charges, and check rules around withdrawing and investing funds, including the minimum deposit amount required.
Some Stocks and Shares ISAs are ‘DIY’, giving you the freedom and flexibility to select stocks, shares and funds that match your values and goals. You can usually access your investment portfolio via a secure digital platform, so you can easily adjust your choices in line with how they’re performing. If this sounds daunting, look into the option of managed portfolios. These are ‘ready-made’ ISAs expertly put together and managed for you by your provider.
Should you wish to invest through a Stocks and Shares ISA but don’t feel confident choosing and maintaining your own investments, a managed portfolio is likely the best route to take. Rather than assessing your own risk tolerance and choosing individual funds and sectors, investment professionals will take on the task on your behalf.
You’ll be matched with a portfolio suited to your risk profile and goals, which will be monitored and adjusted to keep you on track. As a result, you won’t need to research any markets yourself, and your investments remain diversified.
Aiming to save little and often with regular payments can help smooth volatility. It’s advisable to keep money in a Stocks and Shares ISA for 5+ years to increase your chances of positive returns compared to cash savings.
The main benefit of ISAs is that they let you save tax-free – but only up to a point. There is a limit on how much you’re able to save or invest into ISAs each year. The maximum annual ISA allowance for 2025/26 is £20,000. This can be split between multiple Stocks and Shares ISAs or different types of ISAs, but cannot be carried over into 2026/27.
Any profit from assets earned through your Stocks and Shares ISA is free from UK Income Tax and Capital Gains Tax.
