Investment Guide: Stocks, Bonds & Building Long-Term Wealth
9 min read • Updated 2026
Investing isn't just for the wealthy. This guide shows you how to start investing, understand different options, and build long-term wealth.
Why Invest?
Money sitting in a savings account loses value to inflation. Investing helps your money grow faster than inflation over time.
UK Average Returns (Long-term)
- Cash savings: 1-4% (inflation often exceeds this)
- Bonds (gilts): 3-5% (low risk, low reward)
- Stocks & shares (FTSE 100): 6-8% (medium risk)
- Global equities: 7-10% (higher risk, higher reward)
💡 The power of compound interest: If you invest £100/month at 7% annual return, after 30 years you'll have £113,600 — more than double what you put in (£36,000).
Investment Options Explained
Stocks & Shares
Buying a share means owning a tiny piece of a company. If the company does well, the share price goes up and you may receive dividends.
- Individual stocks: Higher risk, potential for higher returns
- Index funds (trackers): Follow the whole market (e.g., FTSE 100, S&P 500) — lower fees, lower risk
- ETFs (Exchange Traded Funds): Like index funds but trade like stocks
Bonds (Gilts)
Bonds are loans to companies or the government. They pay interest (coupon) and return your money at maturity. Lower risk than stocks but lower returns.
- UK government gilts: Very safe, lower returns
- Corporate bonds: Higher risk, higher returns
⚠️ Risk warning: All investments carry risk. Your capital is at risk. Past performance is no guarantee of future returns. Consider speaking to a financial adviser.
ISAs (Individual Savings Accounts)
ISAs are tax-free savings and investment accounts. You can invest up to £20,000 per year without paying tax on gains.
- Stocks & Shares ISA: Invest in shares, funds, and bonds tax-free
- Cash ISA: Tax-free savings account
- Lifetime ISA (LISA): Save for a first home or retirement — government adds 25% bonus
- Innovative Finance ISA: Peer-to-peer lending
📌 ISA rule: Use your £20,000 ISA allowance each year if you can. Any gains are completely tax-free forever.
How Much to Invest
Start small and be consistent:
- Beginner: £50-£100/month into a Stocks & Shares ISA
- Building momentum: £200-£500/month
- Serious investor: £500+/month
