From 8 January 2026, the Construction Products (Amendment) Regulations 2025 will update Great Britain’s construction products framework so that compliance demonstrated under EU rules can satisfy specified domestic obligations. In practice, documentation and assessments prepared in line with Regulation (EU) 2024/3110 will be treated as meeting parts of the retained Construction Products Regulation (EU No 305/2011) when placing products on the GB market. The instrument was made on 6 November and laid on 10 November 2025.
The legal adjustments are targeted. Articles 16A to 16C of the retained 2011 Regulation are revised to set out when manufacturer, importer and distributor duties are fulfilled by complying with EU 305/2011 or with the new EU 2024/3110 regime. Articles 59A and 59B on market surveillance are also updated so that enforcement applies equally where operators rely on EU 2024/3110. In parallel, the Construction Products Regulations 2013 are amended so the same enforcement machinery applies to such products.
For manufacturers, the route to compliance is explicit. Where a product is assessed under EU 305/2011 or the applicable assessment and verification system under EU 2024/3110, and the manufacturer draws up a Declaration of Performance and Conformity (DoPC) in line with Articles 13 and 15 of EU 2024/3110, the relevant GB obligations in Article 16A are treated as met. The instrument also recognises the information that must accompany the DoPC under Article 15(6), and permits reliance on Chapter 7 of EU 2024/3110 for marking and documentation.
Importers may likewise rely on EU compliance. Where the EU 2024/3110 assessment route has been followed, importers can fulfil their GB checks by verifying the DoPC, ensuring the product bears the appropriate conformity marking, and confirming that the manufacturer has completed the required assessment system. Importer identification and record‑keeping obligations continue, alongside duties to act where a risk or non‑conformity is identified.
Distributors’ responsibilities are aligned to the EU model recognised by the instrument. Before making a product available, distributors must confirm it carries the correct marking, is accompanied by the necessary instructions and safety information, and references the manufacturer’s DoPC. If there are grounds to believe a product is non‑compliant, it must not be supplied until rectified, and distributors must cooperate with corrective action.
The DoPC replaces the EU Declaration of Performance and broadens the data set that must be supplied. EU 2024/3110 provides a standardised model and allows digital provision of the DoPC, with language requirements determined by the market in which the product is placed. Environmental and safety characteristics are phased in through harmonised technical specifications and will appear progressively in DoPCs.
Market surveillance is unchanged in form but extended in scope. Trading Standards (GB) and district councils (NI) remain responsible for surveillance and enforcement, and will apply the same powers where an operator relies on EU 2024/3110 to meet GB duties. Formal non‑compliance will include missing or incorrectly prepared DoPCs and failures to provide required information with the declaration; other non‑compliance provisions capture failures to provide instructions, undertake corrective action or cooperate with authorities.
Timelines are clear. The EU regulation entered into force on 7 January 2025, with major application dates from 8 January 2026. EU 305/2011 is partially repealed from that date and fully repealed on 8 January 2040, creating a long transition in the EU. The UK instrument’s recognition of EU 2024/3110 from 8 January 2026 gives GB businesses a consistent evidential route during this period.
For manufacturers placing products on the GB market, the practical effect is a choice between two established compliance pathways: the retained GB version of EU 305/2011 with UK marking, or EU compliance (including the DoPC) that is recognised for the purposes specified in Articles 16A–16C. Importers and distributors should update internal controls, supplier declarations and labelling templates so that DoPCs, marking and supporting information are available at the point of supply and retained as required by the applicable regime.
