3 reasons to consider a Stocks and Shares ISA over a Cash ISA in 2025 Not all ISAs are created equal. And if one is serious about building wealth, it’s important to choose the right investment vehicle. Cash ISAs remain popular. Looking at government figures, there’s currently around £300bn stashed away in these products. If one is serious about building wealth, however, a Stocks and Shares ISA could be smarter. Here are three reasons to consider this type of ISA instead in 2025. Investment funds One advantage of Stocks and Shares ISAs is they (usually) offer access to investment funds. These products provide diversified exposure to the stock market and tend to generate much higher returns than cash savings products (like the Cash ISA, although admittedly it’s a safer option) over the long term. An example of a fund (and one I think worth considering) is Fundsmith Equity. This is a popular product that is invested in about 30 different companies globally. While this fund has had its ups and downs over the years (like all stock market-based investments), it has performed very well over the long term. Since its launch in late 2010, it has returned about 15% per year (before platform fees) – trouncing the returns from cash savings. Investment trusts Stocks and Shares ISAs also offer access to investment trusts. These are similar to funds by providing diversified exposure to stocks, however, they’re traded slightly differently, and often have lower fees. One investment trust I’ve invested in (and I think is also worth others considering) is Scottish Mortgage. This is a growth-focused trust that invests in disruptive businesses like Nvidia and Amazon (it has nothing to do with Scottish mortgages!) This trust can be volatile at times due its focus on tech stocks. However, over the long term it has done well, delivering a share price gain of about 430% over the last decade (roughly 18% a year). Individual stocks Perhaps the biggest advantage of Stocks and Shares ISAs, however, is that they offer access to individual stocks (both UK stocks and international ones). In other words, you can invest in individual businesses. This is riskier than investing in a fund or investment trust. Because every company has its own risks and if something goes wrong, its share price is likely to fall. On the flip side however, there’s potential for much higher returns. With stocks, it’s possible to make 100%, 200% or more from a single investment in a year. One example of a stock that I believe is worth considering today is Uber (NYSE: UBER). A US-listed business, it operates the world’s largest rideshare platform. This company is growing at a rapid rate at present. In 2024, the number of trips booked on its platform rose 19% while the company’s revenue jumped 18%. Looking ahead, I see plenty of growth potential. While the company operates in many countries across the world today, it still has plenty of room to expand to new cities and offer new services (such as train/boat rides). Now, this stock can be volatile at times. Recently it has been swinging around wildly on the back of concerns over Tesla’s robotaxis (which are a potential risk). But over the last five years (which is generally the minimum recommended timeframe for investing in stocks), it has roughly doubled in price. And looking out over the next five years, I see the potential for further gains as the company expands into new markets. Should you invest £1,000 in Uber Technologies right now?

When it comes to Individual Savings Accounts (ISAs), not all options are created equal. If you’re serious about growing your wealth, choosing the right investment vehicle is crucial. While Cash ISAs remain popular, with approximately £300 billion currently saved in them according to government data, a Stocks and Shares ISA could be a smarter choice for long-term financial growth. Here are three key reasons to consider investing in a Stocks and Shares ISA in 2025.

1. Higher Returns Through Investment Funds

One major advantage of a Stocks and Shares ISA is access to investment funds. These funds provide diversified exposure to the stock market, often delivering significantly higher returns than cash savings products such as a Cash ISA—although it’s worth noting that they come with more risk.

A great example of a high-performing investment fund is Fundsmith Equity. This globally diversified fund has delivered an average return of around 15% per year since its launch in 2010 (before platform fees), far outpacing the returns of standard cash savings accounts. Over time, these compounded returns can make a significant difference in your investment portfolio.

2. Access to High-Growth Investment Trusts

Another advantage of a Stocks and Shares ISA is the ability to invest in investment trusts. Similar to funds, these trusts offer diversified stock exposure but often come with lower fees and the potential for higher growth.

One standout investment trust is Scottish Mortgage Investment Trust. This growth-focused trust invests in disruptive companies such as Nvidia and Amazon, making it a compelling choice for investors seeking exposure to cutting-edge industries. While this trust can experience volatility due to its tech-heavy portfolio, it has delivered an impressive share price gain of approximately 430% over the last decade—equating to an annualized return of about 18% per year.

3. The Potential of Individual Stocks

Perhaps the biggest advantage of a Stocks and Shares ISA is the ability to invest in individual stocks, including both UK and international shares. Unlike funds or trusts, investing in individual stocks offers the potential for significant gains, although it comes with increased risk.

One stock worth considering is Uber Technologies (NYSE: UBER). As the world’s largest rideshare platform, Uber has been experiencing rapid growth. In 2024 alone, its total trips increased by 19%, while revenue surged 18%. With ongoing expansion into new markets and services (such as train and boat rides), Uber presents a compelling long-term investment opportunity.

Although stock investments can be volatile—especially with potential industry disruptors like Tesla’s robotaxi development—Uber’s stock has roughly doubled in price over the last five years. Looking ahead, its continued innovation and expansion could fuel further growth for investors.

Final Thoughts

If you’re looking to maximize your investment potential in 2025, a Stocks and Shares ISA offers compelling advantages over a Cash ISA. From higher returns via investment funds and trusts to the ability to invest in high-growth stocks, this ISA type provides greater opportunities for wealth accumulation over the long term.

Before making any investment decisions, be sure to conduct thorough research and consider your risk tolerance. With the right strategy, a Stocks and Shares ISA could be a powerful tool for securing your financial future.
