How to invest in the S&P 500 from the UK

In this guide, we walk you through how to invest in the S&P 500 from the UK, step by step, with ETF and broker data updated in October 2026.

We cover how to choose an S&P 500 ETF, how the main UK brokers compare on fees and what a year of investing costs on each.

Video summary

Watch a short recap of how to invest in the S&P 500 from the UK in our video below:

Step one: pick an ETF tracking the S&P 500

The S&P 500 tracks around 500 of the largest US companies, spanning a wide range of sectors and representing the bulk of the US equity market by capitalisation. As such, investing in the S&P 500 gives you broad exposure to the US economy and can serve as a cornerstone of a well-diversified portfolio.

When investing in the S&P 500 from the UK, buying each of the 500 underlying stocks individually would be costly and impractical. Exchange-traded funds (ETFs) solve this by giving you a single, low-cost investment vehicle that tracks the index as a whole. By investing in S&P 500 ETFs, UK investors can participate in the index’s long-term growth with instant diversification, and they can do so inside a Stocks and Shares ISA or a SIPP (Self-Invested Personal Pension), where gains and dividends are free of UK tax.

The table below shows some of the most popular S&P 500 UCITS ETFs available to UK investors. UK investors should focus on UCITS ETFs (funds that follow EU rules, mostly domiciled in Ireland) rather than US-domiciled ETFs like SPY. US ETFs are generally not offered to UK retail investors because their issuers do not produce the UK key information document required for retail sales (the PRIIPs KID, which the new Consumer Composite Investments regime began replacing on 6 April 2026).

This list was filtered using justETF, a useful tool for finding and comparing European-listed ETFs.

Largest S&P 500 ETFs in the UK

We explain “replication method” and “use of income” later in this guide.

For most UK investors, one of the larger physical S&P 500 UCITS ETFs (iShares CSP1, Vanguard VUSA or VUAG, or State Street SPXL) is a sensible choice, for these reasons:

1. Their Total Expense Ratios (TER) are very low: 0.07% for the iShares and Vanguard options and 0.03% for State Street SPXL, the lowest in our table.
2. The replication method is physical, meaning the ETF actually holds the underlying 500 stocks. Synthetic ETFs (like Invesco SPXP) use swaps to replicate the index instead, which adds counterparty risk, although they can be more efficient on US dividend withholding tax (see below).
3. These are among the largest S&P 500 UCITS ETFs by Assets Under Management (AUM), so they are unlikely to be closed or merged, which matters for long-term holders.

The choice between accumulating (for example CSP1, VUAG or SPXL) and distributing (for example VUSA or IUSA) versions depends on whether you want dividends reinvested automatically or paid out to your account as cash. Accumulating is usually simpler for long-term investing inside an ISA or SIPP.

Step two: choose a good ETF broker

After selecting an ETF, the next step is to choose a broker that offers it. Here is which of the ETFs above each broker lists:

Other factors to compare are fees, the minimum deposit, the range of ETFs and the tax wrappers on offer:

What does a year of investing cost?

To compare brokers in practice, here is the yearly cost of holding £10,000 in VUAG (the GBP line, so no FX fee) inside an ISA, buying once a month:

For a monthly investor with a portfolio of this size, the platforms with no commission or platform fee cost only the ETF’s own fee. HL’s percentage charge grows with your portfolio until it reaches the £150 yearly cap for ETFs, while IBKR’s per-trade cost suits larger, less frequent purchases better.

Step three: place a buy order

Once you have chosen a broker and funded your account, you are ready to place a buy order for the S&P 500 ETF. For this example, we will use Trading 212 (new users can get a free fractional share with our promo code IITW, terms apply).

The steps are similar with any broker:

a) Search for your S&P 500 ETF

Use the search function or browse through the available ETFs to find the specific S&P 500 ETF you have selected. Use the ticker or the ISIN to find the right listing (in our case, we searched for CSP1).

Brokers often list the same ETF in several currencies, such as USD, EUR or GBP. It is usually best to pick the line that matches your account currency.

With a GBP account, choosing the GBP line (such as CSP1 rather than CSPX) avoids currency conversion fees.

b) Click on “Buy”

After selecting CSP1, tap “Buy” on the following page:

c) Choose the order details

Now, choose the order type that fits your preferences and trading strategy:

• Market order: the default on most brokers, including Trading 212. It executes the trade at the current market price, straight away, which suits most long-term ETF purchases.
• Limit order: you set the specific price you’re willing to pay. The trade will only execute if the market price reaches (or falls below) your specified limit. Useful if you want price control rather than speed.
• Stop order: an order to buy or sell once the stock trades at a specified “stop” price, typically used as a risk-management tool.
• Stop-limit order: a conditional order that specifies both a trigger price (when the order activates) and a limit price (the highest/lowest you’ll accept). Combines risk management with price control.

You’ll also need to specify either an amount (a fixed pound figure to invest, e.g. £100) or units (a specific number of shares, including fractions). Many UK brokers, including Trading 212, Freetrade, InvestEngine and IBKR, support fractional shares, meaning you can invest a specific amount even if a single ETF share costs more than your budget allows.

d) Place the order (“Send buy order”)

Click “Send buy order” to submit your order. You will see that no commission is charged (other fees may apply, such as the 0.15% FX fee if you buy in another currency):

e) And that’s it!

Finally, a pop-up will appear to show that your order is confirmed:

What to look for in any ETF?

Not all ETFs are the same, and there are several factors worth weighing up before deciding which one to invest in. Here are the most important:

1. Fees (TER / OCF)

Different asset managers charge different fees for their ETFs. Providers like BlackRock (iShares), Vanguard, State Street (SPDR) and Invesco charge a small annual fee that’s deducted directly from the fund’s assets, so it doesn’t show up as a separate line on your account, but it quietly reduces your returns over time. Choosing a low-fee ETF can make a meaningful difference to long-term performance.

This fee is most commonly expressed as the Total Expense Ratio (TER) or the Ongoing Charges Figure (OCF). For S&P 500 UCITS ETFs, fees start at 0.03% (State Street SPXL) and are higher for currency-hedged share classes, such as 0.10% for the GBP-hedged iShares version. Over 20 years or more, that difference adds up.

2. Replication method

ETFs use two main replication methods:

• Physical replication: the fund actually buys and holds the underlying assets in the index (or a representative sample of them). For an S&P 500 ETF, this means holding actual shares in the 500 underlying US companies.
• Synthetic replication: the fund uses derivatives, typically swap agreements with one or more counterparties, to mirror the index’s performance, rather than holding the underlying stocks directly.

You may also encounter ETFs that blend both methods. Given the very high liquidity of the S&P 500’s underlying companies, physical replication is generally the more straightforward choice, lower counterparty risk, simpler structure, and easier to understand for most investors.

That said, synthetic ETFs (like Invesco SPXP) have one advantage for the S&P 500. Physical Irish-domiciled ETFs pay 15% US withholding tax on the dividends they receive, while a swap-based ETF receives the index’s total return, because US rules exempt swaps on broad indices from this tax. This happens inside the fund, so it applies whether you hold the ETF in an ISA, a SIPP or a general account, and it is why some investors prefer synthetic S&P 500 ETFs despite the counterparty risk.

3. Use of income

ETFs differ in how they handle income (mainly dividends) generated by the underlying companies:

• Accumulating ETFs automatically reinvest dividends back into the fund, increasing the ETF’s price over time rather than paying cash out. You don’t pay transaction costs on the reinvestment, it happens automatically inside the fund. Note that outside an ISA or SIPP, the reinvested income is still taxable in the UK (as “excess reportable income” for reporting funds), so you declare it on your Self Assessment tax return.
• Distributing ETFs pay dividends directly to your brokerage account on a regular schedule (usually quarterly or semi-annually). You’ll need to declare these received dividends to HMRC if held outside a tax wrapper.

The choice depends on your goals. If you are investing for growth and do not need income, an accumulating ETF is usually simpler (inside an ISA or SIPP, dividends are tax-free either way). If you want regular income payments from your portfolio, a distributing ETF is better suited.

4. Fund size

Consider the overall fund size (AUM, Assets Under Management) when choosing an ETF. Larger funds generally carry a lower risk of liquidation than smaller ones, with tighter bid-ask spreads and better day-to-day liquidity. In the event of liquidation, a fund sells its holdings, settles obligations, and returns the remaining proceeds to investors, which can trigger capital gains tax outside a tax wrapper. Sticking to ETFs with at least £500 million to £1 billion in assets is a sensible rule of thumb for long-term investors.

5. Currency hedging

Some ETFs use currency hedging (typically forward contracts) to mitigate fluctuations between the ETF’s listing currency (e.g., GBP) and the underlying assets’ currency (USD for the S&P 500). Hedging adds a small cost (the GBP-hedged iShares share class charges 0.10%, against 0.07% for the unhedged version), but it can protect you against large currency swings in the short term.

Our top S&P 500 UCITS ETFs above are mostly unhedged, since currency fluctuations tend to balance out over long investment horizons, and the hedging cost can drag on returns over decades. For shorter time frames, a GBP-hedged version such as the iShares Core S&P 500 UCITS ETF GBP Hedged (Dist), ticker GSPX, may be worth considering.

The bottom line

Investing in the S&P 500 is one of the most popular ways for UK investors to get broad exposure to the US stock market. Here is a summary of the steps:

1. Pick an S&P 500 UCITS ETF: options like SPXL (0.03% TER), CSP1 (the largest, iShares), VUAG or VUSA (Vanguard, accumulating or distributing) and SPXP (synthetic, Invesco) all track the same index at a low cost. Stick to UCITS ETFs, as US-domiciled ETFs like SPY are generally not offered to UK retail investors.
2. Find a suitable broker: choosing the right broker matters. Consider available ETFs, transaction and platform fees, FX costs, ISA/SIPP availability, and the minimum deposit. Check our list of the top ETF platforms in the UK for an overview.
3. Open an account and deposit funds: once you’ve picked a platform, complete the digital onboarding (typically a few minutes), verify your identity, and fund the account in GBP.
4. Place your order: on your broker’s platform, search for the ETF by ticker or ISIN, choose your order type (market or limit), specify the amount or number of shares, and confirm the trade. Most app-based UK brokers support fractional shares if a full share is too expensive.
5. Hold for the long term: S&P 500 investing is most effective as a long-term strategy. Consider regular monthly contributions (most UK platforms offer recurring investments), and hold the ETF inside an ISA or SIPP to shelter gains and dividends from UK tax.

Always do your own research to decide what suits your situation.
