THE GREEN LIST The government’s Energy Technology List supports efficient lighting technology. Former SLL president John Aston summarises the scheme and considers how qualifying equipment is eligible for ECA tax relief
n the UK lighting accounts for some 20 per cent of the generated electricity despite recent advances in lighting technology and controls. Switching to more efficient lighting units now represents a significant opportunity to reduce energy consumption by 65-85 per cent. While most new construction projects use efficient white lighting there remains a large estate of existing, non-domestic buildings whose lighting could be improved – both in quality and energy efficiency.
q The disruptive change caused by LEDs has led to constant review of ETL criteria
‘In lighting it is not acceptable to focus solely on energy efficiency’
The Energy Technology List (ETL) scheme has supported the adoption of energyefficient lighting technology since 2001. Since this date there have been regular reviews of the criteria that need to be met to qualify for the ETL; the last review was completed in 2017 and the new thresholds came into force in February 2018. The ETL scheme for energy-saving technologies covers a wide range of
products used in the built environment. It is designed to encourage the adoption of the best products available in each of the accepted categories, including lighting. Qualifying equipment is currently eligible for enhanced capital allowance (ECA) tax relief*. Every product covered by the scheme has to meet a number of defined eligibility criteria, which are used as a basis for qualification. Since being added to the Energy Technology Criteria List in 2001, the
