How do I use my InvestEngine code?
InvestEngine does this in a slightly different way to many trading apps. You’ll need to install the app (or register online) and create an account first. Along the way you’ll be prompted to specify which country you pay tax in, and also to provide the sort code and account number for the account you’re going to use to fund the account.
Once you’re all set up, click on the little circle at the top of the app (or web portal) with your initials or profile pic, and from there click on “Personal info“. Here, there’s an option to “Enter a promo code” (see example pics below). Apply your code, and hey presto, you’re set.
Most other apps prompt you to eneter a code during the registration process (didn’t do it at that point? tough luck, you’ve missed the boat). InvestEngine’s approach is a bit more forgiving.
Note that some InvestEngine offers will come with requirements such as funding your account before they’ll be applied.
