Andy has been working in the plumbing and heating industry for over 15 years, originally working in the Cambridge area. With qualifications through NICEIC, City and Guilds and Logic certifications and gaining his Gas Safe registration he worked his way to becoming lead engineer.

After moving to Hemel Hempstead 9 years ago, ASD Heating was created, and it soon became a successful, customer focused business. Over many years Andy worked in collaboration with Kevin and so the idea to merge businesses began. As the saying goes, the rest is history!
