Flexible ISA
A Stocks and Shares Flexible ISA makes investing easy over the medium to long term, based on the growth potential of the stock market.

A Stocks and Shares Flexible ISA is a type of Individual Savings Account that offers flexibility in how you manage your investments. Like a standard Stocks and Shares ISA, we invest your funds in stocks, bonds, and funds, and any returns (capital gains or dividends) are tax-free.
What makes it flexible is that you can withdraw money and replace it within the same tax year without it affecting your annual ISA allowance.
Key Features:
- Tax-free returns: No tax on profits, dividends, or interest earned.
- Annual allowance (2025/26): Up to £20,000 can be contributed across all your ISAs.
- Withdraw and replace: If you withdraw £2,000 and later put it back in the same tax year, it doesn’t count as new money, so long as it’s with the same provider and within the same account.
- Medium to long-term growth potential: Suitable for investors looking to grow their money over several years.
The Stocks and Shares Flexible ISA is designed for UK residents aged 18 or over who are looking to grow their savings over the medium to long term, typically five years or more, while making the most of their annual tax-free ISA allowance.
It’s ideal for individuals comfortable with taking on some investment risk in exchange for the potential of higher returns.
This type of ISA suits those who value flexibility, as it allows you to withdraw and replace money within the same tax year without affecting your allowance.
- Tax-free growth – Pay no income or capital gains tax on your returns.
- Flexible withdrawals – Withdraw and replace money within the same tax year without affecting your ISA allowance.
- Higher growth potential – Invest in a diversified portfolio of stocks and shares for medium to long-term growth.
- Low starting point – Begin investing with just a £25 lump sum or £10 monthly Direct Debit.
- Accessible investing – Designed to suit both new and experienced investors.
- Protected funds – Eligible deposits are covered up to £85,000 by the Financial Services Compensation Scheme (FSCS).
A Stocks and Shares Flexible ISA lets you invest tax-free, with the freedom to withdraw and reinvest in the same tax year without affecting your allowance. Your money goes into the Unity Mutual Equity Fund, which tracks the performance of over 600 UK companies, spreading risk and removing the need for investment decisions.
There's a low 1% annual management fee, and while your money can grow, its value may go down as well as up. Your money is protected by the Financial Services Compensation Scheme (FSCS).
