The Construction Products Regulations 2013. This Statutory Instrument brought the EU Construction Products Regulation (305/2011) into UK law. It created the legal framework that requires manufacturers of certain construction products to draw up a Declaration of Performance and affix the CE mark (now UKCA mark within Great Britain) to their products. This applies to products for which a harmonised European standard exists, such as fire doors and smoke detectors. The regulation aims to ensure reliable information is provided on product performance and to harmonise the market, making it a key piece of legislation governing the safety and quality of construction products. This page provides a structured summary, key provisions, and practical guidance on the application of The CPR Regulations 2013 to UK fire safety engineering, building design, and Building Safety Act compliance.
