If you’ve been pre-approved for a product it means, based on the info you’ve given us, we’ve been told that you’ll be accepted.
But, it doesn’t mean you’re guaranteed to be accepted. The lender will perform their own checks when reviewing your application, such as:
Fraud and ID checks: to make sure you are who you say you are
Checking the details of your application: to make sure the info you provided is accurate
Responsible lending checks: to make sure that lending to you is responsible and you can afford your repayments
Lenders must complete checks on all applications, even where an application is Pre-Approved. This is a regulatory requirement, and lenders must follow the ‘Responsible Lending’ rules set out by the Financial Conduct Authority.
