Yes, in almost all cases, a personal guarantee is required when taking out a business loan. Where required, the PG is signed by the people behind the business, such as a Director or Shareholder. While a personal guarantee will be required, this can be offset slightly by taking out personal guarantee insurance. This type of insurance policy is designed to pay out should your PG be called upon in the event that a business loan falls into default. A PG may not be required for some smaller business borrowing, but this is judged on a case by case basis.
