Can I open a Stocks and shares ISA with an initial lump sum and top up at a later date?
Answer
Yes, you can. When you first open a Stocks and shares ISA, you’ll need to deposit a minimum of £250. After that, you can add as much or as little as you like – just remember to stay within your annual ISA allowance, which for the 2025/26 tax year is £20,000.
ISA allowances renew every 6 April, though any unused allowance doesn't roll over.
You can use your allowance by paying in lump sums, or by adding smaller amounts. To set up a Direct Debit, you’ll need to pay in a minimum of £25 per month, which can then be invested into your chosen assets using our regular investment service.
