Best investments for a self-employed pension - whatever your age

Important information - the value of investments and the income from them, can go down as well as up, so you may get back less than you invest.

If you're self-employed, you don’t benefit from employer pension schemes with default investment funds. That means you’re responsible for choosing how to invest your pension savings within your self-invested personal pension ( SIPP). While that might sound daunting, the good news is there’s plenty of guidance out there to help and it’s simpler than it seems once you understand the basics.

In this article, we’ll cover how to build an investment portfolio, offer some fund ideas and outline some key investing mistakes to avoid.

Why holding cash is costly

One common mistake to avoid is holding too much cash in your pension. While cash feels safe, it loses value over time due to inflation. For example, if inflation runs at 3% annually, £10,000 in cash today will only be worth around £5,500 in real terms after 20 years. Investing helps your money grow and preserve its purchasing power.

Why choosing the right funds matters

Your pension’s long-term success depends heavily on the funds you choose. The right investments can compound over decades, while poor choices - or no choices - can leave your retirement pot stagnant. Fortunately, there are well-diversified, low-cost options that suit most self-employed savers.

Core principles for pension investing

Whether you're 25 or 55, the fundamentals remain the same:

• Start as soon as you can: The earlier you invest, the more time your money has to grow.
• Stay consistent: Regular contributions help to smooth out market ups and downs.
• Think long-term: Pensions are a decades-long journey, not a sprint.

Risk tolerance and age: what you need to know

Your age plays a key role in how much investment risk you should take. Younger savers can afford more risk because they have time to recover from market dips. Older savers may prefer more stability to protect their accumulated wealth.

Diversification: don’t put all your eggs in one basket

Diversification means spreading your investments across different assets, like stocks and bonds, and across different global markets to reduce risk. A well-diversified pension is generally less likely to suffer big losses from any single market event.

Balancing stocks and bonds

Stocks generally offer growth, while bonds provide stability. A common rule of thumb is to subtract your age from 100 to find your ideal stock allocation. For example, a 40-year-old might hold 60% in stocks and 40% in bonds. However, in reality, these allocations may be too low for people to achieve the retirement they want, and pension savers often allocate more to stocks than the “100 minus your age” rule of thumb would suggest.

Best types of funds for a self-employed pension

Our Select 50 is a good place to start for SIPP investment ideas. This is a list of our 50 favourite funds.

A core part of most SIPP portfolios will be a low-cost global index fund. These track the performance of global stock markets and charge minimal fees. So, if the value of global stocks markets goes up, the value of your investments should go up.

On our Select 50 list, there is the Legal & General Global Equity Index Fund, which charges just 0.13%

Alternatively, you could look for a fund that combines stocks and bonds in one wrapper for you. Fidelity’s Retirement Builder is single, medium-risk, low-cost fund that aims to achieve stable growth over the medium to long term (ideally, at least five years). Currently around 60% of the portfolio is invested in stocks and around 40% in bonds.

How to review and rebalance your pension

As you age, your investment strategy is likely to evolve. As mentioned, younger savers can afford to take more risk.

In your 30s and 40s:

Most people focus on growth with a higher stock allocation. Alongside a global stock market fund, you might consider investing in funds that specialise in specific areas of stock markets that could offer higher growth, such as emerging markets or smaller companies.

On our Select 50 list, there is the iShares Core MSCI EM IMI UCITS ETF, which tracks the performance of emerging market stocks, and the Vanguard Global Small-Cap Index Fund, which tracks the performance of a basket of smaller companies around the world.

In your 50s and 60s:

Some investors will gradually shift their portfolio towards bonds and lower-risk assets to avoid big falls in the lead up to retirement. The iShares Overseas Government Bond Index Fund, one of our Select 50, is a low-cost way of getting access to government bond markets.

However, it’s important to avoid derisking too much. If you plan to access your pension via drawdown, you may want to preserve a healthy allocation to stocks, which have better growth prospects than bonds or cash.

It’s good practice to review your pension at least annually. You may need to rebalance your portfolio, which means adjusting allocations to maintain your desired mix of assets. For example, if stocks have grown faster than bonds, you might sell some stocks and buy more bonds to restore balance.

Checklist: common mistakes to avoid

• Too much cash: As mentioned, the value of cash can easily be eroded by inflation.
• Chasing short-term returns: It’s incredibly difficult to time the market and trying to do so can lead to losses. A simpler, and often safer, approach is to drip-feed your money into the market each month.
• Neglecting reviews: Your pension needs regular check-ins to stay on track.
