We'd love you to join Tembo. If you haven't paid anything into your existing LISA this tax year, and don't expect to, then you can open a Tembo LISA straight away. If you have paid into your existing LISA this tax year you can only open an account with us if you transfer your existing LISA to us. Transferring can be done in minutes, and it takes us 4-6 weeks to get the money into your account.
