To clarify the situation, the Carbon Trust said: "Since 2001 the Carbon Trust has supported the UK government in its delivery of the ECA Scheme for Energy Saving Technologies through operating the Energy Technology List.
"It is worth noting that the ECA Scheme and the ETL perform different functions. ECAs provide an incentive for businesses to help strengthen the business case for buying energy efficient equipment through providing a tax break. The ETL enables any organisation – including the public sector – to cost-effectively and credibly identify higher performing energy efficient equipment.
"In the Budget statement of the 29 October 2018, the Chancellor announced that the Enhanced Capital Allowance and First Year Tax Credits Scheme for energy saving technologies will end in about 18 months' time, at the start of April in 2020. This will bring to a close 19 years of continuous accelerated capital allowance tax relief for energy efficient technologies used by industry.
"The government currently has no plans to stop supporting the Energy Technology List, and remains committed to its proposal made in the Clean Growth Strategy to ensure incentives for investment in energy efficiency are regularly reviewed.
"The Chancellor also announced a number of changes to update the ETL Criteria to reflect developments in eligible technologies. Subject to Parliamentary approval, these changes are expected to come into force in 2019. The qualifying criteria for 18 of the existing categories will be revised, and Flow Controllers (a sub-technology of Compressed Air Equipment) will be removed.
"Although the ETL has been a key element to enable the ECA Scheme, it is also an important and valuable tool in itself that organisations of all sizes regularly use to identify higher performing energy efficient equipment across nearly 60 technology categories, such as heat pumps, EC electric motors, retail display cabinets, packaged chillers and LEDs. As of today there are 15,221 products listed on the ETL and it continues to receive strong support from manufacturers, suppliers and their trade bodies.
"Because it is an authoritative and regularly updated resource (new products are added every two weeks), many large enterprises and public sector bodies have embedded the ETL into their procurement processes to ensure they are buying energy efficient equipment that results in lower overall total cost of ownership than alternatives that may come at a cheaper capital cost. Equally SMEs, who often lack the internal resources needed to identify energy efficient equipment, often rely on the ETL as a government-backed, independent, and trusted source of energy efficient equipment from which to select their next equipment purchase.''
