An ISA (individual savings account) is a great way to save your money in a tax-efficient account. A stocks and shares ISA allows you to invest, usually based on the level of risk you are comfortable with.

According to a 2025 Finder survey, 15% of UK adults currently have a stocks and shares ISA.
3.8 million people subscribed to a stocks and shares ISA in the 2022/2023 tax year, down from around 3.9 million people in 2021/2022. A third (31%) of all ISA subscriptions in 2022/2023 made were to stocks and shares ISAs.
The number of subscriptions has grown by over a million since the 2019/2020 financial year when just 2.7 million stocks and shares ISAs were subscribed to.
How many people have a cash ISA?
7.9 million people subscribed to a cash ISA in 2022/2023, up from 7.1 million in the previous year but down from a high of 9.7 million in 2019/2020. 63% of ISA subscriptions were to cash ISAs. In total, almost 12.5 million ISAs were subscribed to in the 2022/2023 tax year.
What is the average return on a stocks and shares ISA?
The average annual return on a stocks and shares ISA over the past 5 years has been 6.37%, compared to 2.08% for a cash ISA. Over the past 10 years, it has been 9.64% annually compared to 1.2% for a cash ISA.
However, the performance of this type of ISA can vary significantly, seeing losses as well as returns over the course of a year. For example, the average stocks and shares ISA experienced a loss of 3.27% between February 2022 and February 2023. The table below highlights the variation in performance year-on-year.
Overall, UK adults placed an impressive £28 billion in stocks and shares ISA during the 2022/2023 tax year, but this was around £6 billion less than in 2021/2022. Brits were putting more money into cash ISAs than the previous tax year, however, with a whopping £41.6 billion put into these accounts – over £10 billion more than the £30.9 billion subscribed in 2021/2022.
Interestingly, in 2021/2022, more money was subscribed to stocks and shares ISAs than cash ISAs. The amount subscribed to cash ISAs had been decreasing steadily, perhaps because interest rates were lower, making cash ISAs less attractive. However, once interest rates began increasing again in 2022 and 2023, Brits were once again placing more money in cash ISAs and less in investment ISAs.
What is the average stocks and shares ISA balance?
Over the last 5 years, the average amount subscribed to a stocks and shares ISA was £8,737. In the 2022/2023 financial year, this was slightly lower at £7,355.
What is the average cash ISA balance?
The average subscription per account for a cash ISA over the past 5 years is lower than a stocks and shares ISA, at just £4,881. However, the average subscription in 2022/2023 was £5,296, almost £1,000 more than the average subscription in the previous tax year.
The average subscription per account for a cash ISA has historically been lower than a stocks and shares ISA. This may be related to a number of reasons, such as the disposable income of those subscribing to a stocks and shares ISA, a larger number of people subscribing to cash ISAs, or worse than typical interest rates on cash ISAs during this period.
