A plain-English guide
If you manufacture, import, or distribute construction products for the European market, you have probably come across the term “CE marking”. And behind CE marking for construction products sits one key piece of legislation: the Construction Products Regulation, or CPR.
But what does the CPR actually say? Why does it exist? And what does it mean in practice for your business? This article breaks it all down in plain English — no legal jargon, no unnecessary complexity.
The basics: what is the CPR?
The Construction Products Regulation (EU) No 305/2011 is an EU law that sets out the rules for placing construction products on the market within the European Economic Area (EEA). It came into force on 1 July 2013, replacing an older directive (the Construction Products Directive, or CPD).
Its core purpose is simple: to ensure that when a construction product is sold anywhere in the EU, there is a common language for describing its performance. Not to guarantee the product is “safe” in an absolute sense — but to make sure that buyers, architects, engineers and regulators across all EU member states can understand what a product does and how well it does it.
Think of it as a shared rulebook for product communication across borders.
What counts as a “construction product”?
The CPR defines a construction product as any product or kit that is permanently incorporated into construction works (buildings or civil engineering structures) and would affect the performance of those works.
This covers an enormous range of products, including:
Structural products: steel beams, precast concrete elements, timber frames
Facade and envelope: windows, doors, curtain walling, cladding panels
Insulation and membranes: thermal insulation, waterproofing membranes
Finishes and sealants: adhesives, sealants, paints, floor coverings
Mechanical, electrical and plumbing: pipes, drainage systems, electrical conduits
Prefabricated kits: entire systems sold as a unit
The key concept: essential characteristics and declared performance
The CPR does not tell you that your product must achieve a certain level of performance. Instead, it requires you to measure and declare the performance of your product against a defined set of characteristics — and to do so consistently.
These characteristics are called essential characteristics, and they are defined in harmonised technical specifications (either harmonised European standards — hEN — or European Assessment Documents — EADs).
Examples of essential characteristics include:
Reaction to fire (e.g. Euroclass A1, B, C…)
Thermal transmittance (U-value)
Compressive strength
Water tightness
Release of dangerous substances
Once you have assessed your product’s performance against the relevant essential characteristics, you declare that performance in a document called the Declaration of Performance (DoP). This is the heart of CE marking for construction products.
What is CE marking, and how does it relate to the CPR?
CE marking is the visible outcome of CPR compliance. Once a manufacturer has:
Identified the applicable harmonised standard or EAD for their product
Carried out the required assessment and verification of constancy of performance (AVCP)
Drawn up a Declaration of Performance
Set up a Factory Production Control (FPC) system
…they can affix the CE mark to their product and place it on the EU market.
It is important to understand that CE marking is not a quality mark or a safety certification. It is a declaration by the manufacturer that they have followed the correct process and that the product’s performance is as stated. Market surveillance authorities in each EU member state are responsible for checking that manufacturers are doing this correctly.
Who does the CPR apply to?
The CPR places responsibilities on different actors in the supply chain:
Manufacturers
The primary responsibility sits with the manufacturer — the person or company that places the product on the market under their own name or brand. They must carry out the conformity assessment, draw up the DoP, and affix the CE mark.
Importers
Companies importing construction products from outside the EU must verify that the manufacturer has completed their obligations before placing the product on the EU market. If the importer places the product under their own name, they take on full manufacturer responsibility.
Distributors
Distributors must act with due care to ensure they only supply products that comply with the CPR. They must not supply products they know — or should know — are non-compliant.
Why does the CPR matter for your business?
If your product falls within the scope of the CPR, CE marking is not optional — it is a legal requirement before you can sell in the EU. Supplying a non-compliant product can result in:
Products being withdrawn from the market
Fines and legal liability
Reputational damage with distributors, contractors and buyers
Loss of access to key EU markets
On the positive side, a correctly CE marked product with a well-prepared Declaration of Performance is a competitive asset. It tells your customers exactly what your product does, how it performs, and that you have followed a rigorous, transparent process to prove it.
Key CPR terms at a glance
CPR
Construction Products Regulation (EU) No 305/2011. The main EU law governing construction products.
DoP (Declaration of Performance)
The document in which the manufacturer declares the assessed performance of their product against essential characteristics.
hEN (Harmonised European Standard)
A European standard that defines the essential characteristics and the test methods for a specific product type. Products covered by an hEN must be CE marked.
EAD (European Assessment Document)
Used for innovative products not covered by any harmonised standard. Issued by a Technical Assessment Body (TAB).
AVCP (Assessment and Verification of Constancy of Performance)
The system for assessing and maintaining the declared performance of a product over time. There are five AVCP systems (1+, 1, 2+, 3, 4), each with different levels of third-party involvement.
FPC (Factory Production Control)
The internal quality control system a manufacturer must operate to ensure their products consistently meet their declared performance.
Summary
The CPR is the foundation of everything related to CE marking for construction products in the EU. It does not dictate the level of performance your product must achieve — but it does require you to assess and declare that performance clearly, consistently, and in a way that can be verified.
Understanding the CPR is the first step towards successful CE marking, whether you are a manufacturer trying to access the EU market or a professional building expertise in construction products compliance.
