What belongs at the heart of your ISA?

By Juliet Schooling Latter on 11 February 2026 in Income investing

It makes financial sense to position a stocks & shares Individual Savings Account (ISA) at the very heart of your overall portfolio. These innovative wrappers enable your nest egg to grow and protect it from both income and Capital Gains Tax.

But what funds deserve to sit at the core of this ISA? How can you choose the most suitable combination for your long-term needs?

Here, we suggest what you must consider, the key qualities a core holding requires and fund options that could be suitable for different investor types.

First steps

You need to be very clear on your investment goals. For example, are you saving for a specific purpose with a future deadline, such as paying school fees? These requirements will dictate the type of core ISA portfolio that meets your needs. You also have to decide how much risk you want to take. If you have a long investment time horizon, then you can afford to take a bit more risk. However, if you’re approaching retirement or hate volatility, a more cautious approach is advisable.

Investment approaches

We have broadly divided investors into one of three camps: Cautious, Balanced and Aggressive. For each of these broad categories, we have defined an average investor and suggested both a one-stop-shop approach and a do-it-yourself option.

Whatever your risk appetite, most core ISA holdings need to have five key qualities:

• A degree of diversification
• Affordable cost structures
• Some growth potential
• Be aligned with your goals
• Good management track record

Cautious investors

Who they are: Cautious investors have a low risk tolerance and are more interested in preserving capital than gambling their life savings. They will be drawn to high-quality government and corporate bonds, and potentially to some holdings in solid, reliable companies.

Multi-asset approach: An established, diversified fund will be appealing. There are plenty of potential candidates within the IA Mixed Investment 0-35% Shares sector. As its name suggests, higher-risk equity exposure is limited to 35%. In addition, at least 45% must be in fixed-income investments, such as corporate and government bonds.

We like a couple of funds in this area. Ninety One Diversified Income aims to provide investors with attractive, sustainable income and scope for capital growth. It targets a yield of around 4% per annum, distributed monthly, with less than half the volatility of UK equities. This enables investors to sleep more soundly.

Another option is the Schroder Global Multi-Asset Cautious Portfolio. This aims to provide capital growth and income by investing in a diversified range of global assets and markets. We believe it should be considered by investors seeking a cost-competitive active solution with a strong focus on risk.

DIY approach: Pick a few funds focused on the main asset classes and place them at the core of your overall ISA portfolio. For example, the IFSL Church House Investment Grade Fixed Interest fund aims to provide a steady, low-volatility, quarterly income stream for investors. You can then consider a fund such as Fidelity Global Dividend. This is a core global income fund that invests in companies that offer a healthy, sustainable dividend yield.

Balanced investors

Who they are: A balanced investor has a moderate risk tolerance. This means they’re willing to accept some risk in pursuit of higher returns. However, they’re certainly not gung-ho. Their ideal portfolio will usually be a mix of equities and bonds, usually in a 60-40% split, while their investment time horizon will be five to 10 years.

Multi-asset approach: Our first multi-asset suggestion is Orbis Global Cautious. This fund invests globally across asset classes, such as equities, fixed income and commodities. It sits in the IA Mixed Investment 20-60% Shares sector, meaning it can have a decent equity weighting, alongside exposure to other areas.

There’s also VT Momentum Diversified Income. The objective of this fund is to provide a high level of regular income while preserving the real value of capital over the long term. The managers have a value-focused style and invest across all asset classes, including UK and overseas equities, fixed income, property and even specialist investments.

DIY approach: Let’s start with Invesco Tactical Bond. This is a strategic bond fund that can invest across the whole fixed-income universe. The risk can be constantly adjusted. For equity exposure, you could consider Capital Group New Perspective. It invests in some of the world’s largest multinational firms and has a team of managers who oversee their respective areas.

Aggressive investors

Who they are: These are investors who have a high tolerance for risk. They will want to maximise their returns as they may have longer time horizons or hold other investments. Their portfolios are likely to have more in equities, particularly higher-risk areas, such as the emerging markets, as well as some high-yield bond exposure.

Multi-asset approach: The IA Mixed Investment 40-85% Shares sector is a good place to start, as it includes multi-asset portfolios with a significant equity weighting. Our first suggestion is Liontrust Sustainable Future Managed, which aims to deliver long-term capital growth. A thematic approach is used to identify key structural growth trends. We see this as a sustainable multi-asset fund that has consistently outperformed over the past couple of decades.

Another fund in this sector worth considering is BNY Mellon Multi-Asset Balanced. This aims to balance income and capital growth over at least five years. The fund predominantly invests in global equities, but also has an allocation to bonds.

DIY approach: You can embrace higher-risk funds, such as GQG Partners Emerging Markets Equity, which has significant exposure to emerging markets such as India, Brazil, and Taiwan.

An alternative is M&G Asian. This is a high-conviction fund managed by a team with years of expe
