Yes. When you combine your loans:
Your current loan(s) are repaid, and your new loan principal will comprise the remaining balance of your those loan(s), plus any new amount you choose to borrow.
You will have one monthly repayment instead of multiple scheduled repayments.
Your repayments become more manageable because your loan term is extended. Don’t worry! You’ll still have the freedom to repay your loan early without any early repayment fees.
