I have explained in my latest BBL post here the below - I hope this will address all your questions.
BBLS lenders have to undertake Know Your Customer (KYC) and fraud checks when giving Bounce Back Loans and we do these checks when you join Tide, therefore most members won’t need to provide us with additional information (we may need some additional information from some members and we will let you know if that’s the case).
Please also note that if we give you access to Tide Bounce Back Loans, you’ll be asked to self-certify some points to confirm your eligibility for the Bounce Back Loan Scheme. We can only offer loans to members who successfully complete this form.
You won’t be asked to sign a personal guarantee on a Bounce Back Loan.
The Government guarantees 100% of your loan with your lender, but you remain liable for all the repayments, as well as the interest after the first year.
