Declaration of Performance DoP

A Declaration of Performance (DoP) is a self-issued document by the manufacturer that declares a construction product's performance characteristics, it was introduced under the EU Construction Products Regulation (CPR) 305/2011 (replacing the Construction Products Directive (CPD) 89/106/EEC) and coming into force on July 1, 2013.

The 2011 regulations were replaced by the Construction Products Regulation (EU) 2024/3110 published in the Official Journal of the European Union on 18 December 2024 entering into force on 7 January 2025. These new regulations replaced the Declaration of Performance (DoP) with a a Declaration of Performance and Conformity (DoPC), alongside the introduction of the mandatory Digital Product Passport (DPP). The new DoPC includes conformity and includes environmental and climate performance on top of the original technical performance specifications. This is seen as a more comprehensive declaration of a construction product's compliance, and alongside the enhanced CE marking it includes environmental impact, and a greater focus on circular economy principles like promoting recycled materials. The industry has been given one year to become familiar with the new requirements which will come into full force in January 2026.

Both the DoP and the DoPC are legal documents written and issued by the manufacturer stating the product performance in terms of its essential characteristics (for DoP) but also wider issues of conformity (DoPC). Their purpose is to provide standardised information about the product's performance, making it easier to compare different products, that can also feed into Environmental Product Declarations (EPDs). A product can then be CE marked once, previously the DoP was created and in the future after the DoPC has been created, and thus responsibility for the declared performance, and in the future also its conformity.
