The best FTSE 100 and UK equity UCITS ETFs
The FTSE 100 is the index of the 100 largest companies on the London Stock Exchange, dominated by banks, energy and consumer staples rather than tech. UK trackers are among the cheapest funds anywhere, and because most FTSE 100 revenue is earned abroad, the index is less of a bet on the UK economy than it looks.
- Cheapest: ISF at 0.07% a year (iShares Core FTSE 100 UCITS ETF).
- Hands-off pick: CSUK, dividends reinvested automatically.
- For income: ISF, pays dividends out as cash.
How this ranking works
Funds are ranked by annual fee (TER), cheapest first, using the same live dataset that powers the rest of TickerCompare; returns are total returns converted to USD and refresh throughout the trading day. Funds tracking the same index are near-interchangeable, so we treat cost as the main tiebreaker and flag dividend policy so you can match the fund to how you invest. This is educational information, not financial advice.
