It depends. Government rules state that you may only have one Bounce Back Loan.
If you’re a sole trader, this means one per person.
If you’re a Director of a limited company, this means one per limited company or group. Two or more companies form a ‘group’ when one or more are subsidiaries of another, or when your companies come under the same holding company.
If you operate as a sole trader and are also the Director of a limited company, then you may have one for your sole trader business and one for your limited company.
