In 1991 a complete review of management, communications, quality control and  customer service systems was initiated to enable HDS Energy to obtain accreditation of its quality management systems to international standards.

Lloyds Register of Quality Assurance have certified the quality management system to ISO 9001: 1994.

HDS is committed to a policy of continuous examination and updating of all quality systems by developing training, testing and checking procedures to ensure that the customer receives products and related services to the highest international quality standards.
