Energy Related Products (ErP) Directive

What is the ErP Directive and does it apply to your products?

The Ecodesign Energy-related Products (ErP) Directive 2009/125/EC was introduced in 2009 and replaced the Eco-Design Directive (EuP). The Directive is part of UK law under the Energy Related Products Regulations 2010 and follows the EU amendment in the Regulations 2016. It impacts on all products “having an impact on the energy consumption during use” being sold in the European Union’s single market.

The aim of the Directive is to reduce energy consumption across the supply chain from design to production, etc.

Compliance with the Energy-related Products (ErP) is essential for CE marking, which covers product safety and energy efficiency requirements.  

How Enertek Can Help

Enertek have a wealth of experience and offer good value in delivering solutions for gas, electric and oil appliances to meet the requirements of the Energy - related Products Directive.

With comprehensive UKAS accredited test facilities for testing space heaters, electrical appliances, hot water storage tanks, water heaters, boilers and micro Combined Heat and Power appliances, Enertek are well placed to conduct test and development work to help your products comply with the ErP Directive in:

  • ErP: Product Efficiency (We have invested in designing and building test rig to conduct hot water tests for tapping cycles 6 and 7, increasing our ability to test water heaters from tapping cycles 1 to 7)
  • ErP: NOx Emissions
  • ErP: Noise/Sound Testing – For the Energy Labeling Directive (Enertek have partnered with Hull University to provide a fully equipped acoustic chamber, capable of conducting noise tests to meet the requirements of the ErP)
  • ErP: Storage Volume for Storage Water Heaters
  • Standing Losses for Hot Water Storage Tanks
  • ErP: Life Cycle Analysis

ErP Directive Regulation Authority

In the UK the ErP Directive is monitored and surveyed by the National Measurements and Regulation Office Enforcement Authority (NMRO) and is based on manufacturers self-declaring. The penalties for incorrect claims may be severe resulting in possible recall of products and sustainable fines. Enertek can provide the independent report required to justify or support claims, it does not have to be produced by a notified body.
