Andrew S. Burcham is an Engineering Technician Member of The Institution of Gas Engineers. He has over 40 years of experience in the gas industry, starting as an apprentice Gas Service Engineer with British Gas in 1981. He worked for British Gas for 25 years, later becoming an assessor and trainer. In 2006, he left British Gas and worked as a self-employed heating engineer while also assessing ACS programs at colleges. Since 2014, Andrew has been the ACS Centre Manager at Colchester Institute, delivering training and assessment programs for plumbing and heating engineers. His depth of knowledge and hands-on experience make him an invaluable resource. Stephen J. Denney is a highly respected tutor and assessor in the gas industry, bringing over 30 years of invaluable experience. After graduating as an award-winning plumbing student in 1991, he established a successful business in mechanical services. In 2014, Stephen became a full-time lecturer and assessor and currently holds a pivotal role at Colchester Institute's Gas and Utilities Department. In this position, he oversees quality assurance and develops industry courses, equipping professionals with essential skills for success in the gas industry. His extensive practical experience, combined with his role as an assessor, enables him to provide valuable insights and real-world perspectives to professionals in the gas and utilities sector. Roy D. Treloar was, until his retirement, curriculum development manager for the Professional Training Centre at Colchester Institute.
