There’s a useful new way to read UK retail finance, and the data set that supports it has just refreshed. Most coverage of UK investing focuses on participation — whether more or fewer adults hold investments year-over-year, whether crypto adoption is up or down, whether ISA usage tracks ahead of last year. Those numbers are interesting but they often miss the more revealing story underneath: the gap between what UK adults say they want from financial products and what they actually hold.
The latest UK investing statistics consolidate the FCA, HMRC, ONS and Action Fraud data sets into a single picture for 2025/26. Read carefully, they describe a UK retail market that is changing on the demand side — preferences shifting, new products being asked for — much faster than the supply side is moving to meet those preferences.
The numbers, briefly
Stripped of commentary, the picture for 2025/26 looks like this:
| Metric | Figure | Source |
| UK adults holding investments | 35% | FCA Financial Lives 2024 |
| Stocks & Shares ISA market value | £511bn | HMRC ISA Statistics |
| Stocks & Shares ISA share of ISA market | 58.6% | HMRC |
| UK adults owning cryptocurrency | 8% | FCA Cryptoasset Research 2025 |
| UK adults aware of cryptocurrency | 91% | FCA Cryptoasset Research 2025 |
| UK adults wanting sustainable investments | 72% | FCA Financial Lives 2024 |
| UK adults actually holding sustainable investments | 18% | FCA Financial Lives 2024 |
| UK investment fraud losses (2024 annual) | £649m | Action Fraud 2024 |
| Crypto share of investment fraud reports | 66% | Action Fraud 2024 |
The story underneath the headline numbers
The 35% participation figure has been the headline for years, and it’s slightly down from 37% in 2022. Read on its own, it suggests UK retail is gently disengaging from the system. That reading is incomplete in a way that matters.
Look at the 91% awareness figure for cryptocurrency. Awareness is at near-saturation. Then look at ownership: 8%. The gap there isn’t an awareness gap — it’s a friction gap. Retail knows what’s on offer. The path to actually holding it doesn’t match the path to learning about it. Whether that’s good or bad depends on the product, but it complicates the simpler narrative of ‘people don’t know about modern investing options.’
The most striking gap is the sustainable-investing pair. 72% of UK adults say they want sustainable investments. 18% actually hold them. That’s the largest stated-versus-revealed-preference gap in any major asset class the FCA tracks. The supply side has built sustainable funds in volume; the demand side has explicitly stated the preference. They aren’t meeting in the middle.
Why the gaps exist
Three explanations cover most of what’s happening, none of them mutually exclusive.
- Defaults dominate. Most platforms route new account-holders toward general-market funds rather than sustainable, ESG, or specialist mandates. Active selection requires more friction than acceptance of the default. In any product where the default is sticky, the population at year-end looks more like the default than user preferences.
- Information asymmetry by where you look first. Marketing copy occupies the top of broker and platform pages; risk disclosures and product specifics sit further down. New users tend to read top-to-bottom. The most consequential information frequently sits where most users don’t reach.
- Fraud loss is suppressing engagement. £649m lost to UK investment fraud in 2024 — with 66% involving cryptocurrency scams — has a chilling effect on retail confidence beyond the direct losses. People who’ve been defrauded, or who know someone who has, become less likely to engage with the system at all, including with legitimate products.
What this means for individual retail decisions
If you’re trying to make a sensible UK retail-investing decision in 2026, the data points at three things worth knowing about your own behaviour relative to the average.
First: defaults aren’t the right thing for most people, statistically speaking. Most platforms default new accounts to general-market funds. Most users want something more specific — sustainable, themed, age-appropriate — and don’t end up holding it. The simple intervention is to actively select your fund mandate at sign-up rather than accepting the default.
Second: the fraud data has implications for behaviour. 66% of UK investment fraud involves cryptocurrency. That doesn’t mean crypto is fraud — most crypto activity is legitimate — but it does mean that the unsolicited-contact crypto offer, the WhatsApp investment group, the cold-call about a ‘trading platform’ is statistically much more likely to be a fraud than equivalent contact about a stocks-and-shares ISA.
Third: stated preference is data. If you say you want sustainable investing and you don’t hold it, that’s a friction problem you can fix in 20 minutes by switching mandate at your existing provider. The gap between 72% wanting and 18% holding is largely closeable at the individual level even if the system doesn’t close it for you.
What the participation breakdown shows
Underneath the headline 35% figure, participation is uneven by income, age, and geography in ways the average obscures. UK adults earning above £50k participate at roughly twice the rate of those earning below £25k. Adults aged 55-64 hold investments at meaningfully higher rates than those aged 25-34. The South East of England consistently shows higher participation than the North East, with the gap larger than income alone explains.
Some of that distribution makes structural sense — investing requires disposable income and accumulates over time. Some of it doesn’t. The regional spread, in particular, points at differences in financial advice access, employer pension scheme structures, and platform marketing reach that aren’t well-explained by income alone. The 35% headline isn’t really a single number; it’s an average across populations whose experiences of UK retail finance look quite different from each other.
Where this is going
The next two-year FCA Financial Lives cycle will likely show whether the supply side is closing on demand or whether the gaps continue to widen. The provider response to the 72%/18% sustainable gap will be especially telling — it’s the largest stated-preference signal the UK retail market has ever produced, and the supply-side response so far has been measured at best. Whether the gap tightens or persists will say a lot about how responsive UK retail finance actually is to its customer base.
The fraud trajectory is the other variable to watch. The £649m investment-fraud figure for 2024 is up substantially on the comparable figure five years earlier, almost entirely driven by cryptocurrency-related cases. If that trend continues, retail confidence in adjacent legitimate products tends to erode alongside the fraud. If it reverses — through better platform-level fraud detection, regulatory enforcement, or public awareness — the participation numbers may rise again.
Either way, the data points consistently in one direction for individual decision-making: defaults aren’t usually the right thing for the person who chose to engage with the system, stated preferences are worth acting on once you know them, and unsolicited investment contact is statistically much more likely to be a fraud than a genuine offer. None of this is dramatic. It’s just what the numbers say.
