Investment Trusts vs ETFs: Which Wins for UK Investors?

Two funds can hold the exact same basket of shares and still hand you very different results — because one is wrapped as an investment trust and the other as an ETF. The investment trusts vs ETFs decision is not really about which portfolio is better. It is about structure: how the shares are created, how the price is set, and whether the fund is allowed to borrow.

Get that structure right and you pick the wrapper that actually fits your goal — income, growth, or the lowest possible cost. This guide breaks down the real differences for a UK investor and shows you which one wins for your situation. If you want the full toolkit behind fund selection, our structured ETF investing course builds it from the ground up.

What is the difference between an investment trust and an ETF?

An investment trust is a closed-ended company listed on the stock exchange: it issues a fixed number of shares, and you buy those shares from another investor, not from the fund. An ETF is effectively open-ended — specialist firms create and cancel shares on demand, which keeps its price glued to the value of its holdings.

That single structural fact drives everything else. Because a trust cannot print new shares to meet demand, its price floats on supply and demand and can drift away from net asset value. Because an ETF can, its price barely moves from NAV. The AIC counts 281 member trusts holding around £265.5bn of assets, so this is a deep, established market — not a niche.

There is a second consequence that matters more than most beginners realise. A closed-ended trust has a permanent pool of capital: no investor can force it to sell holdings to fund a withdrawal, because you sell your shares to another buyer instead. That permanence lets a trust own things an ETF cannot safely hold — commercial property, infrastructure projects, or stakes in private companies that take months to sell. An ETF must be able to redeem daily, so it sticks to assets that trade freely.

Why do investment trusts trade at a discount to NAV?

A trust trades at a discount when its share price sits below the per-share value of its portfolio, and at a premium when it sits above. With a fixed share count and no create-or-redeem safety valve, the price is whatever buyers and sellers agree — and in nervous markets, sellers usually win.

In mid-2026 the average UK investment trust traded at a 9.6% discount to NAV, the narrowest reading in nearly four years after sitting closer to 14% earlier in the year. A discount is a genuine double-edged sword: buy at a 9.6% discount that later closes to zero and you pocket an extra return on top of the portfolio; buy at a premium that collapses and you lose money even if the underlying holds firm.

What this means for you: a discount is not a free lunch. Ask why it exists before you buy. A wide discount can signal a bargain the market has overlooked — or a poorly run trust the market is right to avoid. An ETF removes that judgment call entirely, which is exactly why some investors prefer it.

Cost: why ETFs are usually the cheaper wrapper

Cost is where ETFs win outright, and it is not close. Index ETFs charge as little as 0.03% to 0.10% a year, because tracking an index needs little trading and no research team. Many investment trusts are actively run and charge 0.5% to 2.0%, covering a manager, a board of directors, and audit fees.

Percentages feel abstract, so translate them into money. Here is the annual cost on a £10,000 holding at each fund's headline charge — the gap compounds every single year you stay invested.

What this means for you: if you simply want the market's return, the ETF's 0.03%–0.10% is almost impossible to justify passing up. You only pay a trust's higher charge when you are buying something an index cannot give you — active skill, borrowing, or access to assets that do not trade freely. If cost is your first filter, compare it against our breakdown of index funds versus ETFs and the differences that matter.

Gearing: the borrowing power ETFs don't have

Investment trusts can do something ETFs are built never to do: borrow money to invest. This is called gearing, and across the industry it averages 8% of the portfolio. Used well, it magnifies gains in a rising market. Used at the wrong moment, it magnifies losses just as fast.

Here is the math on a trust geared 10%. For every £100 of your money, it invests £110 (borrowing £10). If the portfolio rises 10%, the £110 becomes £121; repay the £10 and you hold £111 — an 11% gain instead of 10%. If the portfolio falls 10%, £110 becomes £99; after the £10 debt you hold £89 — an 11% loss instead of 10%. Borrowing costs make the downside slightly worse still.

An ETF, by design, tracks its index without leverage, so it never adds this second layer of risk. That is the trade-off in one line: a geared trust can beat the market in the good years and lag it hard in the bad ones. If you cannot stomach an amplified drawdown, gearing is a reason to prefer the ETF.

One practical note: gearing is not fixed. A trust's board can raise or cut borrowing as conditions change, and many hold gearing well below their permitted ceiling in expensive markets. Before you buy, check the trust's current gearing figure and its policy — a headline "8% average" tells you the sector norm, not what any single trust is doing today.

Dividends: the revenue-reserve edge

If you invest for income, the trust structure has a genuine advantage. A trust does not have to pay out all the income it collects each year — it can hold back up to 15% in a revenue reserve and use it to top up dividends in leaner years. An ETF distributes what it receives, so its income rises and falls with the market.

That smoothing power produces long, unbroken records. The AIC's 20 "Dividend Heroes" have raised their payout every year for at least two decades, and half of them have done so for 50 years or more; another 30 trusts sit in the next generation with 10-to-20-year streaks. No ETF can promise that, because no ETF is allowed to stockpile income.

What this means for you: if you want a dependable, rising income you can plan around, a well-run income trust is hard to beat. If you are reinvesting for growth and do not care about a smooth payout, the point is moot — and you may prefer the certainty of an accumulating ETF. Our guide to accumulation versus income share classes shows how that reinvestment choice plays out.

Investment trust vs ETF: the head-to-head

Put the two wrappers side by side and the pattern is clear. ETFs win on cost and price certainty; trusts win on borrowing power, dividend reliability, and access to hard-to-reach assets.

Which should you choose?

There is no universal winner — there is a winner for your goal. Match the wrapper to what you are actually trying to do.

When the ETF wins

Choose the ETF if your priority is low cost, broad index exposure, and a price you can trust to reflect the underlying. For a core holding in the S&P 500, the FTSE 100, or a global tracker, paying 0.07% and never worrying about a discount is the sensible default for most investors.

When the trust wins

Choose an investment trust when you want something an index cannot deliver: a rising, smoothed income; exposure to property, infrastructure, or private companies that need a closed-ended structure to hold safely; or an active manager with a long record you rate. The discount can even hand you a discounted entry — if you understand why it is there.

Whichever you pick, both fit inside a UK Stocks & Shares ISA, so gains and income escape CGT and income tax either way. European investors weighing the ETF route should also read our guide to UCITS ETFs versus US ETFs and what you can actually buy.

Mistakes to avoid with both wrappers

• Buying a trust at a wide premium and assuming it will hold — premiums collapse faster than they build.
• Treating a deep discount as an automatic bargain without asking why the market marked it down.
• Ignoring gearing in a downturn — a geared trust can fall noticeably harder than its index.
• Paying a 2.0% active charge for a trust that simply tracks a mainstream index an ETF covers for 0.07%.
• Judging an income trust on this year's yield alone, rather than its multi-year record of raising payouts.
