The Bounce Back Loan scheme does not specifically state that you must have an existing business relationship with your chosen lender to get accepted for a loan. However, in our experience, lenders will not offer a bounce back loan unless you bank with them already. A very small number of banks will consider applications from new clients (whose businesses were established on or before 1 March 2020), so that means opening up an account with them, but applications are only being accepted on a case-by-case basis; not all businesses would be invited to apply.
