Yes, absolutely.
These one-off contributions, or top-ups as they are also known, can be anything from £1 all the way up until whatever is left of your £4,000 allowance for the tax year.* They typically land either the same, or the next working day, depending on the time of day you have paid in.
You can use this feature to make an instant bank payment as often, or as little, as you would like.
We use our payments partner GoCardless to facilitate this feature, so you may see their name on screen when being guided through the top-up process.
🚨Note that when you first open your account, you can top-up with just £1. For all future one-off contributions the minimum is £10.
