Essential information for suppliers of construction products, including CE marking


This guidance is for England, Scotland & Wales

It is mandatory for manufacturers to draw up a declaration of performance and apply CE marking to any of their construction products that are covered by a harmonised European standard (hEN), or conform to a European Technical Assessment (ETA) that has been issued for them, when such a product is placed on the market.

EU Regulation (EU) 305/2011 laying down harmonised conditions for the marketing of construction products covers four main elements:

  • system of harmonised technical specifications
  • agreed system of conformity assessment for each product family
  • framework of notified bodies
  • CE marking of products

Definition of a construction product

Construction products include products such as doors, windows, shutters and gates, membranes, thermal insulation products, chimneys and flues, sanitary appliances, fire alarms, flooring, fire retardant products, space heating appliances, power cables, glass, and fixings.
