Electric bills are one factor that can affect your credit score. In general, a higher credit score indicates a lower chance of being approved for a loan or being offered a better interest rate on a loan. However, there is no guarantee that electric bills will impact your credit score in the same way. Each variation in your repayment history and credit utilization can have an impact on your score. Additionally, if you've had trouble paying your electric bills in the past, this may also negatively affect your credit score.
