Quick answer: Index funds passively track a market and charge less — often 0.05–0.25% OCF. Active funds employ managers to beat the market and charge more — typically 0.5–1.0%+. Most active funds underperform their benchmark over 10+ years after fees.
The index vs active debate is really about fees and odds. For long-term ISA and pension investors, low-cost global index trackers are the default starting point — active funds need a clear reason to justify higher cost.

How index funds work
They replicate an index (FTSE All-Share, global MSCI World, etc.) by holding the same shares or a representative sample. No manager bets on stock picks — costs stay low.
When active funds get considered
Some investors use active funds for specialist sectors (e.g. smaller companies, ESG screens) or trust structures with gearing. Even then, compare after-fee performance over full market cycles.
Common questions
Are index funds safer?
They have lower specific manager risk but still carry full market risk — prices fall in downturns. Diversification and time horizon matter more than active vs passive label.
