Multi-Asset Funds: A Complete UK Guide for 2026/27
A multi-asset fund gives you shares, bonds, property and cash in a single investment, managed to a target risk level. This guide explains how risk-rated ranges work, active versus passive multi-asset funds, typical fees, and how they compare with building your own portfolio.
What a Multi-Asset Fund Is
A multi-asset fund pools money from many investors and spreads it across several asset classes — typically company shares, government and corporate bonds, sometimes property and commodities, and cash — within a single fund. Instead of buying separate funds for each asset class and managing the split yourself, one purchase gives you a ready-made, diversified portfolio managed to a stated objective.
Risk-Rated Ranges
Most large providers offer a numbered range of multi-asset funds, from cautious through balanced to adventurous, each holding a different proportion of shares versus bonds and cash. A cautious fund might hold mostly bonds and cash with a modest equity weighting to limit short-term volatility, while an adventurous fund might hold 80-100% in shares for higher expected long-term growth with larger swings in value along the way. Picking the right point on the range depends on your time horizon and tolerance for seeing your investment fall in value.
Active vs Passive Multi-Asset Funds
Actively managed multi-asset funds have a manager who selects individual investments or underlying funds and adjusts the asset mix based on their view of markets, aiming to outperform a benchmark. Passive, or index-tracking, multi-asset funds instead hold a fixed blend of low-cost index trackers that is rebalanced back to target periodically, without a manager trying to beat the market. Passive multi-asset funds are generally cheaper, while active ones charge more in the hope of delivering better risk-adjusted returns, which is not guaranteed.
Fees and Charges
The ongoing charges figure (OCF) for a multi-asset fund covers the manager's fee and other running costs, and can range from well under 0.5% a year for a passive multi-asset range to over 1% for an actively managed "fund of funds" that also pays fees to the underlying funds it holds. On top of the fund's own charge, most investors also pay a separate platform fee to the investment platform or SIPP provider holding the fund, so the total cost is the sum of both.
Holding a Multi-Asset Fund in an ISA or SIPP
Multi-asset funds are ordinary collective investments, so they can typically be held inside a Stocks and Shares ISA (within the £20,000 annual ISA allowance), a SIPP, or a general investment account outside any tax wrapper. Held inside an ISA or SIPP, growth and income from the fund are sheltered from Capital Gains Tax and Income Tax, which is usually the most efficient way to hold a multi-asset fund for long-term saving.
Multi-Asset Fund vs Building Your Own Portfolio
Buying a single multi-asset fund outsources asset allocation, fund selection and rebalancing to a professional manager for an all-in fee, which suits investors who want a straightforward, low-maintenance solution. Building your own portfolio from separate index funds covering shares, bonds and other assets can work out cheaper and gives more control over the exact mix, but requires the investor to decide the initial allocation and remember to rebalance it as markets move.
Rebalancing and Target Date Funds
Most multi-asset funds are rebalanced periodically, commonly quarterly or when the mix drifts beyond a set tolerance from its target, to keep risk consistent with the fund's stated objective. A related variant, the target date or "lifestyle" fund often used in workplace pensions, automatically shifts from a higher-risk, growth-focused mix towards cash and bonds as a chosen date such as retirement approaches, without the saver needing to switch funds manually.
