With invest your interest, any interest you earn of £1 or more on your Cash ISA or Simple Saver balance will be automatically moved into your Stocks & Shares ISA each month to be invested in line with your chosen investment allocation. It’s a simple way to help grow your money - we’ll invest your interest directly into your investment allocation, so you don't have to lift a finger!
You’ll be able to invest your interest as long as you have a Simple Saver or a Cash ISA with a balance of at least £5,000. If your balance falls below £5,000 after you enable invest your interest, your interest will continue to be invested each month provided it's £1 or more.
You can turn invest your interest on or off, and manage which cash account you want to invest with in the Moneybox app in Settings > Invest your interest. Once enabled, your interest will be moved into your Stocks & Shares ISA the next working day after it's paid on the first of the month. From there, it will be invested into your investment allocation, and this can take up to 5 working days to settle.
To track your invest your interest payments, go to Wealth > Tap your account > Activity. You’ll be able to see the interest being paid out from your Cash ISA or Simple Saver, and the corresponding investment into your Stocks & Shares ISA.
