Energy Saving Recommended: Change in Glazing Certification Criteria

January 2010

Glazing has been endorsed under the Energy Saving Recommended scheme since February 2005. The certification criteria have now been updated by the Energy Saving Trust to reflect increased market penetration of endorsed products and  updated standards.

The criteria for Energy Saving Recommended glazing will be:

Window Energy Rating label of B or above from British Fenestration® Rating Council (or equivalent e.g  NSAI).

In line with Scheme procedures, the development of the new endorsement criteria went through a consultation and peer review process. The Energy Efficiency Partnership for Homes Glazing Strategy Group were consulted on proposal and representatives of businesses, test houses and other stakeholders attended a consultative forum in order to discuss the proposal, which was then presented to the independent Energy Saving Recommended Endorsement Panel for review. The Endorsement Panel, a body of independent environmental, regulatory, certification and enforcement experts recommended to the Energy Saving Trust that the criteria for endorsement of glazing be changed as proposed. The Energy Saving Trust will be implementing this recommendation.
