Keep in mind that investments can go down as well as up in value, so you could get back less than you put in. A rule of thumb is to hang on to your investments for at least five years to give them the best chance of providing the returns you want.

How to Invest in ETFs in the UK

Investing in ETFs (Exchange-Traded Funds) has become a popular and accessible way for UK investors to grow their wealth. Whether you're a seasoned pro or just starting out, ETFs offer a diversified and cost-effective way to invest in various asset classes, sectors, and markets. So, how do you actually go about investing in ETFs in the UK? Let's break it down.

How to Invest in ETFs in the UK

Step 1: Choose Your Platform

The easiest way to invest in ETFs in the UK is through an online stockbroker or investment platform, such as InvestEngine, Interactive Investor, or eToro. These platforms make it simple to buy and sell ETFs, but they offer more than just transaction services.

When selecting a platform, consider things like:

  • Fees: Look for platforms with competitive transaction costs, as high fees can eat into your investment returns. Use our ISA Calculator to see how your investments might perform against a range of fees.
  • Tax Wrappers: Consider platforms that offer tax-efficient investment accounts, such as ISAs or SIPPs, to help you maximise your returns.
  • Ease of Use: A user-friendly interface or a well-designed mobile app can make managing your investments much smoother, especially if you're new to the game.
  • Range of ETFs: Make sure the platform offers a wide variety of ETFs so you can diversify your portfolio.

Step 2: Do Your Homework

Beyond just being places to trade, most investment platforms provide a wealth of educational resources. This is particularly valuable if you're new to ETFs or investing in general. Many platforms offer market analysis, tutorials, and tools to help you craft a portfolio suited to your goals and risk tolerance.

Investing isn't about making quick decisions based on trends or tips. Take time to research the ETFs available on your chosen platform. Look at things like:

  • Underlying assets: What stocks, bonds, or commodities does the ETF track?
  • Performance history: While past performance isn't everything, it can give you some insight into how the ETF has fared during different market conditions.
  • Expense ratio: This is the annual fee you pay as a percentage of your investment. Lower is usually better, but it is important to weigh this against the ETF's performance.

Step 3: Make Your Investment

Once you've selected a platform and identified the ETFs that align with your investment strategy, it's time to make your purchase. Most platforms make it as simple as selecting the ETF, deciding how much you want to invest, and confirming the transaction. Keep in mind that ETFs are typically bought in shares, but many platforms allow you to purchase fractional shares, making it easier to start with smaller amounts.

Remember, investing is a long-term game. Don't panic at short-term market fluctuations. Instead, focus on your overall strategy and adjust it as necessary based on your financial goals.

Step 4: Reinvest Dividends

Many ETFs pay dividends—distributions of earnings that companies within the ETF make to their shareholders. While it might be tempting to pocket these dividends, reinvesting them back into your ETF is a great way to build wealth over time. Some platforms, like InvestEngine, even allow you to reinvest dividends automatically, which helps you harness the power of compounding.

Reinvesting your dividends can have a massive impact on your portfolio's growth. Over the long term, compounding returns (earning interest on your existing interest) can make a huge difference to your total wealth.

Step 5: Review and Rebalance Your Portfolio

One of the keys to successful investing is periodically reviewing and rebalancing your portfolio. As time goes on, your investments might drift away from your original strategy. For instance, if stocks perform better than bonds in your portfolio, you might find that you're now overexposed to equities, which can increase your risk.

Rebalancing involves selling some assets that have grown beyond your target allocation and buying others that have underperformed to bring your portfolio back in line with your goals. This process keeps your risk levels in check and ensures your investments stay aligned with your long-term strategy.

Bonus Tip: Follow the Bogleheads Approach

If you're looking for a time-tested investing philosophy, consider taking some inspiration from the Bogleheads community. Named after John Bogle, the founder of Vanguard and pioneer of index investing, the Bogleheads approach centres around keeping investing simple. The philosophy is built on a few core principles:

  • Invest in low-cost index funds or ETFs: Keep fees to a minimum to maximise your returns.
  • Diversify: Spread your investments across different asset classes to manage risk.
  • Stay the course: Focus on long-term goals and avoid reacting to market noise.

This no-fuss, long-term approach can be an excellent guide for UK investors looking to build wealth with ETFs. While it might not offer the excitement of stock-picking, the evidence suggests it is an effective strategy for most people, particularly when paired with regular contributions and a hands-off approach.


Investing in ETFs in the UK is straightforward and accessible, thanks to the wide range of platforms available. With some research and a clear plan, you can build a diversified portfolio that helps you grow your wealth over time. Whether you are looking to invest in the UK market or tap into international opportunities, ETFs offer a flexible and low-cost way to start investing.

Remember, investing isn't about timing the market but about time in the market. Stick to your strategy, reinvest your dividends, and review your portfolio periodically. Over time, these small but consistent actions can make a significant difference in your financial future.
