Investing in retirement

Why a low-cost passive strategy could make sense for your pension 

Many people assume that investing stops at retirement. But in reality, your pension often remains invested long after you stop working. 

That makes your investment strategy in retirement just as important, if not more so, than during your working life. Withdrawing from your pension while keeping it invested introduces new risks and considerations. 

In this article we explore: 

Why your pension stays invested in retirement 

Unless you use your whole pension pot to buy an annuity or take it all as cash, your savings will likely remain invested – especially if you’re using flexi-access drawdown. 

This means your pension: 

  • Continues to grow (or fall) based on market performance 
  • Requires regular monitoring to ensure it’s aligned with your income needs 
  • Can have a big impact on how long your retirement income lasts 

Making the right investment decisions in retirement is critical to long-term financial security. 

Active vs. passive investing – what’s the difference? 

Before diving into why low-cost passive investing can be a strong strategy in retirement, let’s briefly define the two main styles of investing: 

Active investing 

Usually, active investing means hiring a fund manager who then chooses what stocks and bonds to invest your money in. The aim is to use research, analysis and personal expertise to try and beat market returns.  

This means investing in assets that are likely to increase in value over the short to medium term and avoid investing in things that are likely to decrease in value. Whatever the skills and experience of the specific fund manager, this approach still contains an element of trying to predict the future. 

Passive investing 

Passive investing is rooted in the work of a group of economists and scientists who, in the 1970s, demonstrated that stock markets generally rise over time. You can see this in action by typing FTSE 100 into Google and then clicking the Max view.  

Whilst we cannot guarantee that stock markets will always rise over the longer term in the future, accepting the premise set out by those economists and scientists does give us a different perspective. Rather than trying to beat stock market returns, the aim is to match them. 

Passive investing is often associated with index funds or exchange-traded funds (ETFs) that offer broad market exposure with minimal fees. Put simply, broad market exposure means investing as widely as possible rather than putting all your eggs in a small number of baskets. 

Why passive investing appeals in retirement

For retirees looking to draw income from their pension, a low-cost passive approach offers several potential advantages: 

  1. Lower costs = more money for you 

Every pound spent on fees is a pound that doesn’t stay in your pension. Over 20+ years of retirement, high charges can significantly reduce your income and therefore the choices you have when it comes to how you live your life. 

Passive funds typically charge a fraction of what active funds do—often 0.10%–0.25% vs. 0.75%–1.5% or more for actively managed funds. 

That difference adds up over time and boosts the sustainability of your retirement income. 

  1. Consistent predictable exposure 

Passive funds don’t rely on a manager’s judgment. They track the market—whether it’s UK equities, global bonds, or a diversified mix of the two. 

That can make it easier to: 

  • Understand what you’re invested in 
  • Monitor your performance 
  • Avoid sudden surprises from a fund manager’s decisions 

This predictability can be valuable in retirement, where income stability often matters more than chasing high returns on your investments. 

  1. Diversification made easy 

Passive strategies allow you to own hundreds or thousands of tradable assets (securities) across different markets, sectors and geographic areas, often in a single fund. 

This diversification reduces the impact of any one company or sector underperforming, which is important when you are accessing your pension and cannot afford big losses. 

  1. Strong long-term track record 

Decades of research suggest that most active managers underperform the market over the long term—especially after fees. For a recent example, read this article. 

In retirement, where preserving your money and managing risk are often more important than trying to outperform the market, passive investing offers a low-cost, evidence-based alternative. 

While a passive strategy can lower costs and simplify your portfolio, it’s not a silver bullet. It still involves: 

  • Market risk – investments can fall in value 
  • Currency risk – fluctuating exchange rates can be a factor if investing globally 
  • Sequence risk – withdrawing money when markets are going down in value can affect your rate of sustainable income 

The key is to structure your investment portfolio around your income needs, time horizon and risk tolerance. Passive funds are the building blocks. You still need a plan for how to use them effectively. That’s where financial advice comes in. 

How financial advice can help

Whilst this article offers general guidance, building an appropriate investment strategy in retirement is a personal decision. 

A qualified financial adviser can help you: 

  • Assess your income goals and time horizon 
  • Determine the right mix of assets (equities, bonds, cash) 
  • Choose cost-effective passive funds that align with your objectives 
  • Set up a withdrawal strategy that protects against risk 
  • Rebalance your portfolio as needed 

At Pension Sense, we use low-cost passive funds as part of a tailored retirement income strategy, offering clients simplicity, transparency and strong value for money. 

Final thoughts 

The shift from saving to spending your pension is one of the biggest transitions you’ll ever make financially. Getting your investment strategy right can mean the difference between income that runs out and income that lasts. 

A low-cost passive approach can offer many benefits: reduced fees, diversified risk and a straightforward way to stay invested for the long term. 

But it’s not just about picking a few index funds, it’s about having a plan that works with your income goals, tax position and lifestyle. Tax treatment depends on your circumstances and is subject to change.
