Certificate of Constancy of Performance COCOP
A Certificate of Constancy of Performance (CoCoP) is awarded to a product if the standards it claims to have met have been achieved through testing systems that have been agreed and harmonised throughout the EU, or designated by the UK and that the product has been manufactured with these standards in mind. A CoCoP can only be awarded in line with standards set by the Assessment and Verification of Constancy of Performance (AVCP) system, which defines how to assess products and how to control the constancy of the assessment results.
On 18 December 2018, the government laid a statutory instrument to ensure a functioning CPR regime when the UK left the European Union. This statutory instrument delivered the policy approach set out in a technical notice published on 13 September 2018.

The government made legislation in March 2019 which came into effect on 1 January 2021 to make arrangements for the regulation of construction products after EU Exit.
The legislation which made amendments to the regime for construction products post the transition period were:
- Construction Products (Amendment etc.) (EU Exit) Regulations 2019
- Construction Products (Amendment etc.) (EU Exit) Regulations 2020
- Construction Products (Amendment etc.) (EU Exit) Regulations 2022
- The Construction Products (Amendment) Regulations 2025
On 2 September 2024 the Minister for Building Safety and Homelessness issued a written ministerial statement regarding recognition of the CE marking for construction products. The CE mark will continue to be available when placing construction products on the market in Great Britain. The UK mark (also known as the UKCA mark) can also be used.
On 7 January 2025 the revised EU Construction Products Regulation (EU) 2024/3110 was published in the Official Journal of the European Union on 18 December 2024 came into force, which includes the introduction of the mandatory Digital Product Passport (DPP). The new CPR will become more generally applicable from 8 January 2026 giving the construction industry one year to familiarise itself with the new legal framework. 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. 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, thus coinciding with the full EU regulation from January 2026.
