What is the minimum and maximum I can invest?

To open a Stocks and shares ISA with us, the minimum amount you would need to invest is £10.

For the 2025/26 tax year, the total ISA allowance is £20,000, which applies across all your ISAs combined. That means the amount you can contribute to your Webull Stocks and Shares ISA depends on how much you've already contributed to any other ISAs this tax year. It's a flexible ISA meaning you can take out cash then put it back in during the same tax year without reducing your current year's allowance. You are responsible for tracking your contributions.
