A direct lender is a financial institution that offers loans to customers without the need for a broker or other third party. You apply directly to the lender, and they offer the money directly to you (assuming you are approved).
Getting a loan from a direct lender means you only deal with them. Your details won’t be passed onto or shared with third parties without your knowledge.
