Mandatory product policy is set at the EU level: the Energy Efficiency Labelling Directive from 1995[1] and the Ecodesign Directive for energy-related products (ErP Directive), setting Minimum Energy Performance Standards since 2005. National action to improve the energy efficiency of lights and appliance pre-dates both of these and continues to make a significant impact, encouraging the uptake of the most energy efficient products and phasing out the least efficient.
