You may find a guarantor for a loan online, if you have bad credit or no credit history. A guarantor is someone who agrees to be responsible for repaying the debt if you can’t, so if you default on the loan, your guarantor will be liable for the repayments. Lenders will usually determine whether you need a guarantor or not when they’re assessing your eligibility, so when your credit score is poor, having a third party to guarantee your loan may help you access finance you may struggle to get otherwise.
