A quick overview of investments

Investing is the process of putting your money into assets; such as stocks, bonds, property, or funds, with the goal of growing your wealth over the long term. Unlike cash savings, investments offer the potential for higher returns that can outpace inflation, though they come with varying levels of risk.

You can read more about how it works in our investment advice article.

Key features of investments

The key components of investing and the general rules around it are:

  • Can be started with a one-off lump sum or regular monthly contributions

  • Gains are often achieved through capital growth (increase in asset value) or income (dividends and interest)

  • Investments are typically held within tax-efficient ‘wrappers’ like Stocks & Shares ISAs

  • Compounding allows your returns to earn their own returns over many years

  • Portfolio diversification helps manage risk by spreading money across different industries and regions

  • Values can go down as well as up, meaning you could get back less than you put in

Eligibility criteria and risk factors

To start investing in the UK, you generally need to be a UK resident and at least 18 years old, though Junior ISAs can be opened for children by a guardian. You will need a UK bank account and a National Insurance number for tax-wrapped accounts. Most platforms have a minimum entry point, which can be as low as £1 to £25 for digital ‘robo-advisors’ or significantly higher for bespoke wealth management.

This table highlights the factors that impact an investment’s performance and the level of risk involved.

Factor

Impact & Key Provider Checks

Risk Tolerance

Providers assess your ‘appetite for risk’ to ensure your portfolio matches your comfort level with volatility of performance

Time Horizon

Investing is usually recommended for a minimum of 5 years to allow time to recover from market fluctuations

Platform Fees

Management fees, platform charges, and trading costs can significantly reduce your net returns over time

Asset Allocation

The mix of equities (higher risk) vs. bonds or cash (lower risk) is the primary driver of your portfolio's stability

Inflation

To build real wealth, your investment return must exceed the current rate of inflation

Tax Status

Using an ISA or Pension wrapper prevents Capital Gains Tax (CGT) and Dividend Tax from eating into your profits

FAQs

Saving involves putting money into cash-based accounts (like a high-street savings account) where your principal is secure and earns a fixed or variable interest rate. Investing involves buying assets that fluctuate in value. While saving is safer for short-term goals or emergency funds, investing historically offers much higher potential for long-term growth and protecting your money from inflation.

THINK CAREFULLY BEFORE SECURING OTHER DEBTS AGAINST YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON A MORTGAGE OR ANY OTHER DEBT SECURED ON IT.

IF YOU ARE THINKING OF CONSOLIDATING EXISTING BORROWING YOU SHOULD BE AWARE THAT YOU MAY BE EXTENDING THE TERMS OF THE DEBT AND INCREASING THE TOTAL AMOUNT YOU REPAY.
