The Energy Technology Product list (ETPL) is a UK government-managed list of energy efficient plant and machinery, such as boilers, electric motors and machinery that qualify for full tax relief. For a product to be on the List, it must meet specific energy-saving or energy-efficiency criteria; this is a part of the Enhanced Capital Allowance (ECA) tax scheme for businesses.
