Open the factsheet for almost any actively managed UK equity fund and you'll find a five-year chart, a manager photo, and a paragraph about "disciplined, high-conviction stock picking." What you rarely find on page one is the number that actually matters: how much of your return the fund's fees quietly took before you ever saw it. Compare that factsheet against a tracker's one-page summary — same asset class, a fraction of the cost — and the question writes itself. Is the person picking your shares actually worth what you're paying them?
What the SPIVA Scorecard Actually Measures
S&P Dow Jones Indices has published its SPIVA (S&P Indices Versus Active) scorecards since the early 2000s, and the Europe edition breaks results out by UK, European and global equity categories. The methodology is blunt: take every actively managed fund in a category at the start of the period, measure its return net of fees against the relevant S&P benchmark, and count how many failed to keep up — including funds that were merged away or shut down along the route, so the laggards can't quietly disappear from the sample. Over rolling ten-year windows, SPIVA Europe has repeatedly found that a clear majority of actively managed UK equity funds underperform the S&P United Kingdom BMI net of fees, and in most reporting periods that figure has sat comfortably above 80%. This isn't a one-off bad decade for UK stock-pickers either — the same pattern shows up in the US large-cap, European and global equity categories, which suggests the problem isn't a quirk of the FTSE 100's sector mix but something structural in how hard it is to beat a market persistently after costs.
None of this means every active manager is mediocre. It means that identifying the ones who aren't, in advance, from a factsheet and a star rating, is far harder than the fund management industry's marketing would have you believe.
Fee Drag Is Not a Rounding Error
Take a fund charging a 0.90% ongoing charges figure (OCF) — roughly the UK active equity average — against a FTSE All-Share tracker like Vanguard's FTSE UK All Share Index Unit Trust at 0.06%, or the iShares Core MSCI World UCITS ETF at 0.20% if you'd rather go global. On a £50,000 ISA growing at a notional 6% a year before fees, that 0.84 percentage point gap compounds to roughly £9,000 of difference over 20 years, purely from cost — before you've even asked whether the active fund managed to beat the index gross of fees in the first place. Fund fees don't fluctuate with performance in bad years the way people assume; you pay the OCF whether the manager has a brilliant year or a dreadful one, and it comes straight off the top of your return every single year, compounding against you the same way your investment growth compounds for you.
Platform charges stack on top of this and get overlooked even more often. A 0.25%–0.45% annual platform fee on a six-figure ISA or SIPP, combined with an active fund's OCF, can easily push your total annual drag past 1.3%. Run the sums before you commit new money, not after you've already been in a fund for three years and are reluctant to sell at a loss.
Where Active Management Has Actually Earned Its Fee
The picture is less one-sided the further you move from large, liquid, heavily researched markets. Small-cap and frontier-market equities, where analyst coverage is thin and prices don't instantly reflect new information, are the segment where SPIVA's underperformance rates have historically been narrowest — sometimes close to the 50% mark rather than 80%+. Investment trusts add a structural edge here too: their closed-end format means a manager running a small-cap or emerging-market portfolio isn't forced to sell good positions into a falling market just because retail investors are redeeming, which is exactly the pressure that hits open-ended active funds during a sell-off.
Fundsmith Equity is the case UK investors reach for most often, and fairly so — Terry Smith's fund comfortably beat the MSCI World index across most of its first decade after launching in 2010, at an OCF around 0.94%, by holding a genuinely concentrated book of 20-30 quality-growth names and refusing to trade around macro noise. Lindsell Train Global Equity built a similar reputation on the same concentrated, low-turnover style. Both funds have had a rougher run more recently as growth-style investing fell out of favour — which is itself the honest caveat: past outperformance from a skilled manager is real, but it is not a permanent state, and the investors who piled into Fundsmith at its 2020 peak have had a materially worse experience than the ones who bought in 2012.
Survivorship Bias Is the Story You Don't Hear
Woodford Equity Income is worth remembering precisely because it's the story that doesn't make it into most "why active management works" arguments. Neil Woodford ran one of the best-regarded UK equity income track records of the 2000s at Invesco, launched his own fund in 2014 to enormous inflows, then suspended it in June 2019 after a liquidity crunch from illiquid unlisted holdings left investors unable to withdraw their money for months — many took a permanent capital loss when the fund was eventually wound down. Every SPIVA underperformance statistic you read already accounts for failures like this, because the methodology tracks funds that closed or merged rather than dropping them from the sample. Marketing materials for surviving active funds generally don't.
A Practical Framework Rather Than a Binary Choice
You don't have to pick a side. A core-satellite structure — the bulk of your ISA or SIPP in a broad, low-cost index tracker, with a smaller allocation to one or two active funds or investment trusts in areas where skill genuinely seems to persist — gets you the fee-efficient market return on most of your capital while leaving room for conviction bets you actually believe in. Somewhere between 70% and 90% in core index exposure is a sensible starting split for most UK investors building long-term wealth through an ISA; where you land within that range depends on how much research time you're honestly willing to put into monitoring the active portion, because a satellite fund you never revisit isn't a satellite strategy, it's just an expensive tracker you forgot to switch.
If you do run a satellite allocation, hold it to a standard: three consecutive years of underperformance against its own stated benchmark, after fees, is your trigger to sell — not a gut feeling, not "give it one more year," and not loyalty to a manager whose name you recognise from a magazine cover.
- Check the OCF on every fund you hold, not just the headline platform fee
- Compare active fund performance against the actual benchmark stated in its own KIID or factsheet, not a vague sector average
- Favour investment trusts over open-ended funds for small-cap and emerging-market active exposure, where the closed-end structure limits forced selling
- Treat a five-star Morningstar rating as a description of the past, not a forecast — the rating methodology is backward-looking by design
What This Means for Your ISA or SIPP Right Now
With the £20,000 ISA allowance and the £60,000 SIPP annual allowance both running for the current tax year, most UK investors adding new money in 2026 should default to a low-cost global index tracker as the base of the portfolio, then decide deliberately — not by inertia — whether an active satellite earns its place. Don't outsource that decision to a best-buy list or a platform's "featured funds" page; those placements are frequently paid for, and a fund's presence there tells you nothing about its net-of-fees prospects for the next decade. Pull up the actual ten-year record against the stated benchmark, check the current OCF rather than the one from an old factsheet, and ask honestly whether you'd still hold the fund if it had a different, less familiar manager's name on it.
