- HMRC recorded about 3,080 ISA accounts with balances of £1 million or more for the year.
- There were 38,680 stocks and shares ISAs with at least £500,000, compared with 30 cash ISAs at that level.

- InvestEngine, which obtained the data, frames the gap as evidence for long‑term investing, and reporting notes heightened speculation about cash ISA limit changes before the Budget.
