What are UK All Companies funds?

They are funds in the IA UK All Companies sector that invest at least 80% of their assets in UK-listed equities whose primary aim is to achieve capital growth. These portfolios will generally have the freedom to invest in companies of different sizes, from FTSE 100 giants to smaller, innovative businesses. This sector differs from both the IA UK Equity Income sector, which focuses on dividend-paying companies, and the IA UK Smaller Companies sector.

Why invest in UK funds now?

Although the UK stock market has traditionally been undervalued compared with its major international peers, its performance last year was strong. The FTSE 100 rose above 10,000 points for the first time in early 2026, fuelled by improving investor sentiment.

The UK market is heavily weighted towards more traditional industries, with large positions in financials, consumer staples, energy and materials. Unlike the US market, it has relatively low exposure to technology companies. This gives investors exposure to a different mix of businesses, including both defensive sectors and more cyclical areas that can benefit when economic conditions improve.

Managers of the best UK investment funds can choose from more than 1,600 companies trading on the London Stock Exchange (LSE), ranging from multinational giants to smaller, innovative businesses operating in niche sectors.

Types of UK All Companies funds

The UK All Companies sector is diverse. It contains a wide variety of funds, each with a different focus and investment style. Here are some examples:

Growth funds

Managers of growth funds focus on companies with the potential for strong earnings, sales and profit growth. These often include technology and healthcare businesses. The best UK equity funds can favour smaller companies whose growth prospects are under-appreciated by the market.

Value funds

Undervalued companies whose qualities are out of favour by stock market analysts are the favoured holdings of the best UK funds with a value focus. Many of these are referred to as special situations. This means their value has been adversely affected by factors such as corporate changes or recovery from a challenging period.

Additionally, UK value funds often also offer higher yields compared to growth or broader market funds. This is because they tend to focus on out-of-favour sectors such as financials, energy, and materials, which typically pay higher dividends.

Blend/quality funds

Some of the best-performing UK funds contain a mix of growth and value characteristics. This means companies with strong competitive advantages and predictable cash flows. Finding the best UK funds will depend on your financial objectives, attitude to risk, and which investment style is most suitable.

Quantitative and enhanced index funds

These funds use systematic, rules-based models to pick stocks with preferred characteristics, such as value and quality. Their aim is to modestly outperform a particular benchmark, such as the FTSE All-Share, by applying a quantitative overlay rather than simple replication.

Passive/index tracker funds

The best UK index funds will closely monitor the performance of the stock market or particular indices. Some, for example, will track the FTSE 100 or FTSE All Share.

Why fund selection matters — not all UK funds are equal

Even among the best UK investment funds, no two portfolios will be identical. That’s why it’s crucial to know what you’re looking for and to scrutinise them properly. The reality is that only a relatively small number of portfolios will outperform over multiple time periods, which is why independent analysis is crucial.

How to choose the best UK fund for you

It’s not just a case of choosing the best-performing UK funds over recent years. You’ll need to consider many factors to identify the top UK funds to invest in.

Define your objective

Are you seeking exposure to growth companies or an alternative revenue stream from an equity income portfolio? Do you want the best UK investment funds that hold FTSE 100 giants, those focused on smaller companies, or a multi-cap fund for broad exposure to UK companies?

Understand the investment style

Managers of the best-performing UK funds may have different investment styles. For example, some may focus on defensive businesses that generate stable cash flows and pay regular dividends. Others prioritise smaller businesses with higher growth potential.

Check the market-cap focus

Some UK All Companies funds will be heavily weighted towards the FTSE 100 giants, while others will invest more in mid and small-cap names. Others will be diversified across all three.

Review performance across multiple time periods

Everyone wants to own the best-performing UK funds. However, it’s important to consider what returns the manager has achieved over various time periods. One outstanding year – or one very poor year – may be due to a specific issue. That’s why you need to know how a manager has performed in different market conditions.

Review costs

Charges and fees can impact returns. When comparing the best UK funds, pay attention to the Ongoing Charges Figure (OCF). This is a percentage representing a fund’s annual operating costs. You must also consider entry and exit charges, transaction costs, and any performance fees.

Look for independent, rigorous research

Independent analysis is required to help identify the best UK funds. FundCalibre’s experienced analysts have years of experience in researching portfolios. This can help investors select the top UK funds to invest in.

Where do UK funds fit in a portfolio?

The best UK funds can adopt different roles. For example, some of the best UK equity funds offer diversified exposure and can serve as a core holding for investors. However, they can also be used as satellite positions in a broader global portfolio. It all depends on their investment goals, attitude to risk and existing holdings.
