Question: I know Rachel Reeves is likely to cut the cash ISA allowance later this year or next year, and I think I should maybe start looking into investing as an alternative. Can I do it myself, or do I really need to get someone to manage my money?
Answer: With rumours swirling that Rachel Reeves could use her Mansion House speech to announce a cap on how much can go into a cash ISA, there’s growing concern this could be a step in the wrong direction for ordinary savers.
The change reportedly under consideration would not reduce the overall ISA allowance, but would instead restrict how much of it can be held in cash, potentially limiting it to £4,000 or £5,000 a year. The idea is to encourage more investment in the economy, particularly in UK companies.
Whether this will prove effective is up for debate. Some would argue that incentivising investment might be a better route than reducing the cash threshold, though that’s a discussion for another article. For ordinary savers, the more immediate impact is on how they use the ISA to manage their money.
Cash ISAs have long played a quietly vital role in people’s finances, and curbing them risks doing more harm than good. They offer a simple, tax-free home for savings, often used to build an emergency fund or put money aside for short-term goals like a house deposit or the early years of retirement.
Many pensioners, in particular, lean heavily on them for stability and peace of mind. For those who already use the full £20,000 allowance, cutting the amount that can be held in cash could create a dilemma: move into investments, or hold excess savings outside the ISA altogether.
Before diving into the question of how to choose a stocks and shares ISA, it’s worth being clear about what the term actually means. The ISA itself is simply a tax-efficient wrapper. What shapes your outcomes is the mix of investments held within it. That could be a cautious bond fund, a balanced multi-asset portfolio, or a high-growth global equity fund. The risk and return come not from the ISA itself, but from the underlying investments it contains.
That’s why two people can both have stocks and shares ISAs and end up with very different experiences. One might be relatively steady and income-focused; another might fluctuate sharply with the markets.
This variation matters, especially if the money is intended for short-term use. Investments tend to be better suited to goals that are at least five years away, and while there are lower-risk options available within the wrapper, they still carry some volatility.
For those who do need to look beyond cash, the question becomes how to choose what goes into the ISA. Some people are happy to keep it simple with a low-cost tracker fund—such as an S&P 500 ETF—that offers broad market exposure and minimal ongoing management. Others may prefer a managed stocks and shares ISA, where a portfolio is built and adjusted for them over time.
The appeal of a managed approach often lies in the structure and reassurance it provides, helping align your investments with your goals and appetite for risk. Managed portfolios tend to be diversified, regularly rebalanced, and designed to keep you invested through market ups and downs.
That sort of consistency can be particularly helpful if you are unsure how to construct a portfolio yourself or tend to second-guess your choices when markets get choppy.
Of course, cost plays a part. Passive options are generally cheaper, and for confident investors, they remain a strong choice. But for those who would rather not make all the decisions themselves, or who want to feel that someone is keeping an eye on things, the extra fee attached to a managed option might feel worthwhile.
If the government does move ahead with a cap on cash ISAs, it may simply restrict how much people can shelter in cash tax-free, rather than prompting a meaningful shift into investment. Some may be left unsure of where to put their money, particularly if they are not ready to take on investment risk.
Cash will always play a valuable role, particularly for short-term goals or as a rainy-day reserve. Undermining its place in the ISA system may ultimately leave cautious savers with fewer good options. Encouraging more investment for those it’s suitable for is a sensible aim, but cutting the cash ISA allowance is unlikely going to meet it meaningfully.
