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 the performance of 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 while benefiting from instant diversification – and crucially, do so within tax-efficient wrappers like a Stocks & Shares ISA or a SIPP, where allowed.

The table below shows some of the most popular S&P 500 UCITS ETFs available to UK investors. UK investors should focus on UCITS-compliant ETFs (rather than US-domiciled ETFs like the original SPY), since US ETFs aren’t available to UK retail investors under PRIIPs rules.

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

Largest S&P 500 ETFs in the UK

Don’t worry if you’re unfamiliar with the meanings of “replication method” and “use of income” – we’ll explain them later in this guide. Now, let’s move to the second step: choosing the broker and placing your trade.

For most UK investors, we’d recommend one of the larger physical S&P 500 UCITS ETFs (iShares CSP1/SXR8, Vanguard VUSA/VUAG, or SPDR SPYL) for these reasons:

1. Their Total Expense Ratios (TER) are very low – 0.07% for the iShares and Vanguard options, and just 0.03% for SPDR SPYL, which makes SPYL currently the cheapest S&P 500 UCITS ETF available in Europe.
2. The replication method is physical, meaning the ETF actually holds the underlying 500 stocks. Synthetic ETFs (like Invesco SPXP) use swap-based derivatives to replicate the index instead, introducing additional counterparty risk – though they can be more tax-efficient on US dividends in some cases.
3. These are among the largest S&P 500 UCITS ETFs by Assets Under Management (AUM), making them very unlikely to be closed down or merged – an important consideration for long-term holders.

The choice between accumulating (e.g. CSP1, VUAG, SPYL) and distributing (e.g. VUSA, IUSA) versions depends on whether you want dividends reinvested automatically or paid out to your account as cash. Accumulating is typically more efficient for long-term wealth building inside an ISA or SIPP.

Step two: choose a good ETF broker

After selecting an ETF, the next step is to identify a reliable broker to let you invest in it. To do this, we’ll provide a brief summary of what each broker offers on their platforms.

Other important factors to consider when selecting an ETF broker are the fees, minimum deposit requirements, the range of available ETFs, and if they offer ISA accounts. Here is a summary of these factors for each broker:

Fees and product counts are approximate as of 2026 and change regularly. Always check the broker’s current pricing before opening an account.

Step three: Place a “Buy Order”

Once you have chosen a suitable ETF 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. However, you can follow these steps to execute your purchase with any broker:

a) Search for the desired 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. Refer to the ticker symbol to locate the ETF accurately (in our case, we searched for CSP1).

You may encounter instances where the broker offers multiple versions of the same ETF denominated in different currencies, such as USD, EUR, or GBP. It is advisable to select the ETF that aligns with your account currency.

For example, as a British investor with a GBP-denominated account, choosing a GBP ETF will help you avoid currency exchange fees.

b) Click on “Buy”

After selecting the CSP1 ETF, you will see the following page and just tap “Buy”:

c) Choose the order details

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

• Market order: set by default on most brokers like Trading 212 – this executes the trade at the prevailing market price and provides immediate execution. Best for most retail investors making 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, Lightyear, IBKR, and others – 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 notice that no commission is charged:

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, SPDR (State Street), 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 currently range from 0.03% (SPDR SPYL) to around 0.20% for hedged variants – a meaningful spread over 20+ years of compounding.

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) can have one notable advantage for S&P 500 investing: under US tax law, swap-based ETFs can avoid the 15% withholding tax on US dividends that physical ETFs incur. For long-term S&P 500 investors holding outside an ISA or SIPP, that small structural edge can compensate for the additional counterparty risk – which is why some sophisticated investors actually prefer synthetic S&P 500 ETFs.

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 in the UK, dividend income is taxable regardless of whether it’s distributed to you, so accumulating ETFs held outside a tax wrapper (like an ISA or SIPP) can still create a dividend tax liability that’s reported via your annual self-assessment.
• 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’re investing long-term for growth without needing income, an accumulating ETF tends to be simpler and more tax-efficient (especially inside an ISA or SIPP, where dividends are tax-free anyway). 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 have tax implications outside a tax wrapper. Sticking to ETFs with at least €500 million-€1 billion AUM 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 comes at a small additional cost – typically increasing the TER by 0.10%-0.15% – but 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 or income-focused investors, a hedged version like iShares S&P 500 EUR Hedged UCITS ETF (IUSE) or its GBP-hedged equivalents may be worth considering.

The bottom line

In conclusion, investing in the S&P 500 from the UK is one of the most popular ways to gain broad exposure to the US stock market. Here’s a summary of the steps:

1. Pick an S&P 500 UCITS ETF: options like SPYL (cheapest at 0.03% TER), CSP1/SXR8 (largest, iShares), VUAG / VUSA (Vanguard, accumulating/distributing), or SPXP (synthetic, Invesco) all track the same index with low management fees. UK investors should stick to UCITS-compliant ETFs since US-domiciled ETFs (like SPY) aren’t available to UK retail investors under PRIIPs rules.
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. Fractional shares are widely supported by modern UK brokers if buying full shares is too expensive.
5. Hold for the long term: S&P 500 investing is most effective as a long-term strategy. Consider setting up regular monthly contributions (most UK platforms support this via AutoInvest or recurring orders), and ideally hold inside an ISA or SIPP to shelter gains and dividends from UK tax.
