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
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.
