Declaration of Performance and Conformity DoPC

A Declaration of Performance and Conformity (DoPC), is a self-issued document by a manufacturer that declares the performance or technical characteristics of a product but also its conformity to environmental and climate standards. DoPC was introduced 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, and replaced the previously used Declaration of Performance under the EU Construction Products Regulation (CPR) 305/2011 (and the Construction Products Directive (CPD) 89/106/EEC). The 2024 CPR regulations also introduced the the mandatory Digital Product Passport (DPP), giving one year for familiarisation and coming 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.

As a result in the UK the Construction Products (Amendment) Regulations 2025 (Statutory Instruments 2025 No. 1172) was laid before Parliament on 10th November 2025 with a view to being in force from 8 January 2026, aligning with the EU CPR full introduction These regulations make minor technical amendments to ensure continuity of the current policy which enables ‘CE’ marked construction products to be sold in Great Britain, after the full EU regulation is in place.
