Your Money
You don't need a lot of money. You don't need to understand markets. You need to start, and you need to start simply.
Figures reflect UK data as of 2026. Always verify specifics before making financial decisions.
Most people delay investing because they think they need to understand markets, pick the right stocks, or have enough money for it to matter. None of those things are true. The barrier to investing sensibly in 2026 is lower than it has ever been — and the cost of not starting is higher than most people realise.
Leaving money in a cash savings account feels safe. Over short periods, it is. Over long periods, inflation silently erodes its value. At 2.5% annual inflation, £10,000 in a savings account today is worth approximately £7,800 in real terms in ten years — even if the nominal balance has grown slightly through interest.
Investing in diversified index funds has historically returned 7–10% annually over long periods. That is not a guarantee — markets fall as well as rise — but over 20, 30, or 40-year horizons, the direction of well-diversified global equity investment has been consistently upward. The risk of not investing — guaranteed erosion by inflation — is just as real as the risk of investing.
An ISA (Individual Savings Account) is a wrapper that makes your savings or investments tax-free. There are two main types relevant at this stage:
A savings account where interest is tax-free. Good for your emergency fund or money you need within the next 1–3 years. Returns are limited to the interest rate — typically 4–5% in current conditions, but historically lower.
An investment account where any gains, dividends, and growth are completely tax-free. This is where long-term wealth is built. Suitable for money you will not need for at least 5 years — ideally much longer.
The annual ISA allowance is £20,000 per tax year (2025/26) — you can split this across both types as you choose. Any growth inside an ISA is tax-free forever. Capital gains tax and dividend tax do not apply. If you hold investments outside an ISA and they grow significantly, you will owe tax on the gains. Inside an ISA, you will not.
Rather than buying individual stocks — trying to pick which company will perform best — an index fund buys a tiny piece of hundreds or thousands of companies at once. If one company fails, it barely dents the overall return. The fund tracks the performance of the market as a whole.
This matters for two reasons. First, the evidence is clear that most professional fund managers fail to consistently beat the market over long periods. Second, index funds charge significantly lower fees than actively managed funds — and fees compound against you in exactly the same way that returns compound for you.
The most widely recommended starting point for UK investors is a global index fund — one that covers companies across the US, Europe, Asia, and emerging markets. Examples: Vanguard FTSE All-World ETF (VWRP), iShares Core MSCI World ETF (SWDA), or the Fidelity Index World Fund. You do not need to choose between them — they are broadly similar.
£100 per month invested in a global index fund at 8% average annual return for 40 years grows to approximately £349,000. Of that, you contributed £48,000. The rest — £301,000 — is growth. Most of that growth happens in the final decade, which is why stopping early is the only real mistake you can make.
This is also why time in the market beats timing the market. Trying to invest when prices are low and sell when they are high is a strategy that consistently underperforms simply staying invested through cycles. Set up a monthly contribution and do not touch it when markets fall.
Best for beginners. Low platform fee (0.15%), limited but excellent fund selection, clean interface. The natural starting point for most people.
0% platform fee for ETFs. Particularly good if you plan to invest in exchange-traded funds (ETFs) rather than funds. Slightly more technical UI.
Fractional shares, easy app. Good for starting with small amounts. Stocks & Shares ISA available. More features than beginners typically need, but accessible.
High-fee platforms and actively managed funds in your early years. A 1% annual platform fee compounds against you at the same rate your returns compound for you.
For most beginners, one global index fund is sufficient. Pick one of the following and set up a monthly direct debit:
Do not overthink this. The difference in long-term outcome between these three funds is negligible. The difference between picking one and starting versus spending six months researching is enormous.
If you are aged 18–39, you can open a Lifetime ISA (LISA) and contribute up to £4,000 per year. The government adds a 25% bonus on everything you put in — up to £1,000 free per year.
The LISA has two permitted uses: buying your first home (on a property worth up to £450,000) or retirement after age 60. If you withdraw for any other reason, you pay a 25% penalty — which effectively claws back the bonus and takes a small slice of your own money too.
For most 18 year olds, the LISA is worth opening if you think you might buy a home within 10–15 years. The government bonus is too valuable to ignore if you qualify and can commit to one of the approved uses.
Open a Stocks & Shares ISA. Set up a monthly direct debit into a global index fund — even £50 per month. Do not touch it when markets fall. Add to it when you can. That is the entire strategy for most 18 year olds. Everything else is complexity that does not improve the outcome at this stage. Start simple. Stay consistent. Let time do the work.
