7 Best ETFs for a Stocks and Shares ISA in the UK (2026)

The Autumn Budget lands this Wednesday, markets have been choppy, and plenty of beginners are wondering the same thing: “What should I actually put in my ISA?” You don’t need to pick the next big winner. Many everyday investors simply use low-cost ETFs, and this guide walks you through seven popular ones, what each does, and the catch to watch for.
An ETF (exchange-traded fund) is a basket of investments, such as hundreds or thousands of company shares, that you buy in one go, just like a single share. A Stocks and Shares ISA is a tax-friendly account that lets you invest up to £20,000 a year without paying UK tax on gains or dividends. Put the two together and you get easy, diversified, tax-efficient investing. Easy peasy.
Where this list comes from: the funds below are drawn from Fidelity UK’s ranking of best-selling ETFs on its platform between 1 January and 30 September 2026 (published 7 October 2026). Popular does not mean “best for you” or “will go up”. Always read each fund’s factsheet.
Why ETFs are so popular for ISAs right now
Recent tech wobbles and oil price jitters are a reminder that single shares can swing wildly. ETFs spread your money across lots of companies, so one bad apple matters less. They also tend to be cheap, and the annual charge (the fee the fund takes, shown as a percentage) is usually far lower than an actively managed fund.
Inside an ISA, any growth stays tax-free, which is why many investors fill their ISA with ETFs first.
The 7 best ETFs to consider for your ISA
1. Vanguard FTSE All-World
What it is: one fund holding around 3,755 companies across developed and emerging markets. Fidelity lists its annual charge at 0.14%.
Why it matters now: it was the top-selling ETF on Fidelity this year, and it’s the classic “one-and-done” option for beginners.
Watch out for: roughly 61.6% sits in US companies, so it’s global, but not evenly spread.
2. Vanguard S&P 500
What it is: tracks the 500 biggest US companies (see our guide to investing in the S&P 500), with an annual charge of 0.07% according to Fidelity.
Why it matters now: America’s giants have driven much of the market’s growth, and this was another top seller.
Watch out for: you’re betting on one country and a handful of big tech names, so it can fall hard if US tech stumbles.
3. Invesco FTSE All-World
What it is: a rival to the Vanguard fund tracking the same type of global index, with 2,091 holdings including around 4.2% in emerging Asia.
Why it matters now: it’s a popular alternative if you want global exposure from a different provider.
Watch out for: it holds fewer companies than the broadest funds, so check the fees and holdings side by side.
4. Vanguard FTSE Global All-Cap
What it is: a very broad fund with 6,405 stocks, including smaller companies as well as the giants.
Why it matters now: Fidelity only added it in early September, so it’s a newer option for investors who want even wider spread.
Watch out for: small companies can be more volatile, and newer funds have a shorter track record.
5. iShares MSCI World ex USA
What it is: developed-market shares excluding the US, with the eurozone (29.1%) and Japan (22%) as major regions.
Why it matters now: if the US feels pricey or tech worries you, this tilts you away from it.
Watch out for: it leaves out the US completely, so on its own it is not a full global fund. Many people use it alongside a US or global tracker.
6. Vanguard FTSE All-World High Dividend Yield
What it is: global companies that pay above-average dividends (cash payments to shareholders). Fidelity shows a 2.6% yield versus 1.2% for the standard All-World fund.
Why it matters now: appealing if you want income, and a steadier feel when growth stocks wobble.
Watch out for: dividends aren’t guaranteed, and income-focused funds can lag in strong growth markets.
7. VanEck Semiconductor (higher risk)
What it is: a focused fund holding chip makers, including names like ASML, SK Hynix and TSMC. Fidelity reports it had risen 91.3% in 2026 so far.
Why it matters now: AI demand has driven chip stocks, and this made Fidelity’s top 10 sellers.
Watch out for: this is a concentrated bet on one industry. Falls of 20-30% are possible, and past gains don’t predict the future. If you hold it at all, keep it a small slice.
How to choose the right ETF for you
- Keep it simple: a single global tracker (our guide to how to choose an index fund helps) can cover most of what a beginner needs.
- Check the ongoing charge: small differences compound over decades.
- Mind the concentration: how much is in the US, or in one sector?
- Match your timeframe: shares suit money you won’t need for five years or more.
What to do next
- Check your ISA allowance: it’s £20,000 for the 2026/27 tax year (6 April 2026 to 5 April 2027).
- Pick a platform with low fees (compare the best investment platforms) and open a Stocks and Shares ISA.
- Choose one core ETF, such as a global tracker, and read its factsheet and key information document.
- Start small (how much do you need to start investing?). Drip-feeding, say monthly, smooths out the ups and downs.
- Be patient. Review once or twice a year rather than checking daily.

Frequently asked questions
