How can I start investing with only £100?

Britain is encouraging more people to start investing with the Savvy the Squirrel campaign, urging opening a Stocks and Shares ISA. Chancellor Rachel Reeves said that from April 2027 the annual ISA allowance will fall from £20,000 to £12,000 for anyone under 65, leaving up to £8,000 available for Stocks and Shares investments. Anita Wright, Chartered Financial Planner at Ribble Wealth Management, cautions that investing differs from 'squirrelling' and emphasizes the need for a risk-aware strategy. For beginners, opening a Stocks & Shares ISA can be tax-efficient, with platforms including Vanguard UK, Trading 212, Freetrade and AJ Bell, each offering different fees and features to compare before opening an account. With £100, diversification is crucial; many beginners opt for a global index fund containing hundreds or thousands of companies to reduce single-stock risk, with options such as Vanguard FTSE Global All Cap Index Fund, Vanguard FTSE All-World UCITS ETF and iShares MSCI World ETF. Though £100 is a start, regular contributions—£25, £50 or more monthly—can generate meaningful compound growth over time.
