How to start investing: a beginner’s guide
Starting out in investing can feel daunting. It’s easy to feel overwhelmed by the jargon, the range of choices, and the risk involved. Isn’t it better to stick to safe, dependable cash?
In short: no. While cash ISAs and savings accounts are less risky in the short term than investing in stocks and shares, cash is a poor way to grow your wealth over the long term, because it barely keeps pace with inflation.

Research from Fidelity International found that £20,000 saved into a cash ISA on 6 April 2017 would now be worth £23,549. But to keep up with inflation over that period, it would have needed to grow to £27,000.
The same amount invested into a global tracker fund in a stocks and shares ISA would now be worth £50,700, according to the analysis. That’s more than double the initial investment in nominal terms, and reflects an annual growth rate of around 12%.
If fear of the short-term risks associated with investing is holding you back from getting started, you’re not alone.
“In the UK, fear of loss seems to be overshadowing fear of missing out,” said Duncan Ferris, analyst at Freetrade. “But avoiding investing can harm savers over the long term, as inflation eats away at the real terms value of cash savings.”

How finance companies and the government are supporting beginner investors
On 10 December, nineteen leading companies in the investments sector announced their membership of the UK Retail Investment Campaign. The campaign is set to launch in April 2026 and aims to increase awareness of the importance of investing to grow wealth over the long term.
The campaign is funded by the 19 firms, which include leading investing firms like Hargreaves Lansdown and J.P. Morgan Personal Investing, but is supported by His Majesty’s Treasury (HMT), the Financial Conduct Authority (FCA), and the Money and Pensions Service (MaPS), with the Investment Association acting as secretariat.
“By bringing together firms from across the financial sector with a shared goal, we aim to make investing more accessible and give people better support when it comes to taking their first steps,” said Sasha Wiggins, chief executive of Barclays Private Bank and Wealth Management, who chairs the campaign.
“This campaign is about providing clear, accessible information so everyone can feel confident in deciding whether investing is right for them,” Wiggins added.
“Unfortunately, the UK is chronically underinvested, with only around a quarter of adults choosing to put their money to work in investments,” said Claire Exley, head of advice and guidance at J.P. Morgan Personal Investing. “Our tendency towards cash and our aversion to risk when it comes to investing could be holding people back from achieving their financial goals.”

What is the difference between saving and investing?
Saving is about short-term wealth protection, while investing grows wealth over the long term.
“Saving is for stability, investing is for growth,” says Rob Morgan, chief investment officer at Charles Stanely. “When saving the aim is to build up a buffer, either for emergencies or for planned spending.”
Cash holdings are suited to this short-term cover because, whatever happens, your savings will be worth at least as much a year from now as they are today.
Investing means taking more risk over the short term for greater rewards over the long term.
“The key ingredient is time,” says Morgan. “The shorter period you invest over the higher chance of loss rather than gain, which is why investing only becomes reliable over a five-to-ten-year horizon – and ideally longer.”
Even if your investments fall in the short term, they will likely more than recover those losses, and beat inflation, over the longer term.
The global economy is cyclical: busts naturally create the conditions that lead to the next economic boom, and the stock market reflects this cycle. The dot-com bust – the longest stock market downturn in the last century – lasted just two and a half years.
That doesn’t mean that all investments are created equal. Where you choose to put your money makes a big difference. But luckily for beginner investors, some of the simplest investments are often the best.
Should beginners pick stocks or invest in funds?
A ‘share’ is a unit of ownership of a company that entitles the owner to a share of the company’s profits. ‘Stock’ – as in ‘the stock market’ – technically refers to all of a company’s shares, though it is used interchangeably with ‘share’. ‘Equity’ is another word for stocks and shares, referring to the part of the company that shareholders own.
A fund, meanwhile, is a bundle of shares (and/or other asset types). For beginner investors, funds generally represent a safer approach to investing because they are more diversified.
Buying shares in a company effectively bets the entirety of the investment on that particular company doing well. Buying a fund spreads the investment across multiple companies. This diversification tends to reduce the likelihood that your investment will fall in value, compared to investing in any one of the stocks the fund holds.
“Instruments like mutual funds offer anxious or bearish investors a chance to gain exposure to stocks, bonds, and more, without putting all their eggs in one basket,” says Ferris.
The stock market is a very different thing from an individual stock, and over the long term, stock markets tend to increase in value ahead of inflation. Funds that track the stock market are a simple way for beginner investors to tap into this trend.

How much money do you need to start investing?
One widespread myth about investing is that you need to have a lot of money to start out with to make it worthwhile. Freetrade’s analysis showed 33% of people felt that a lack of disposable income was what held them back from investing more – the highest proportion of any response.
The truth is that as long as you have a savings buffer in place, there is no minimum level that is worth investing.
“People usually think about investing once they have sufficient cash savings for emergencies,” says Exley.
“That includes having a savings buffer to cover unexpected expenses – typically three to six months’ worth of outgoings,” adds Chris Beauchamp, chief market analyst at IG.
This ought to cover any emergencies or large purchases you’re considering within the next five years.
It is also worth minimising any high-interest debt before you start investing. “‘Bad debt’ – like high-interest credit cards, BNPL arrangements or overdrafts – drains your finances and should be paid off quickly,” says Morgan.
But once this is in place, investing any excess, even very small amounts, “can build confidence and knowledge, providing the life skills to successfully build wealth over time,” Morgan adds.
How old do you have to be to start investing?
There is no upper or lower age limit on investing. The earlier you get started, the better, as your investments will have longer to compound and earn you money. “It’s like a snowball rolling downhill,” says Morgan. “The earlier you start, and the longer you let it roll, the bigger it gets.”
But even those approaching retirement age, or already retired, can benefit from sound investing.
“Someone in the 80s or 90s may be investing for their heirs rather than themselves. You can therefore start – or continue – investing at any age,” says Morgan.
He adds that investment strategy should evolve with age.
“For example younger investors can typically afford to take more risk and focus on long-term growth.” Older investors or those approaching retirement generally favour a more conservative approach.
Where to start investing as a beginner
If you think you’re ready to start investing, it’s easy to get started using an investment platform.
Some will offer a selection of ready-made portfolios, allowing you to select a given risk profile – usually low, medium or high. These are known as robo-advisers.
Alternatively, once you have opened your stocks and shares ISA with your chosen provider, you can start investing into the funds, stocks and trusts of your choice.
As with savings, it pays to start an investing habit. “There are benefits to investing gradually over time,” explains Exley. You can set up a direct debit to pay a set amount in each month, or pay in a lump sum if you prefer.
Some platforms may have a minimum monthly amount or lump sum to pay in to get started, but many will let you start with a pound.
