What are the minimum and maximum amounts I can invest in an ISA?

You must invest a minimum of £500 to open our Stocks and shares or Lifetime ISAs, but you can invest as little as £25 per month if you want to make regular payments.

The maximum you can invest across all types of ISA under the current regulations is £20,000 for the 2017/18 tax year. The maximum you can invest in a Lifetime ISA is £4,000 per year.
