For projects in England, Scotland and Wales, construction products imported from China can currently carry either UKCA or CE marking — the UK government continues to recognise CE marking for construction products in Great Britain, with no confirmed end date. Northern Ireland still follows EU rules, so products delivered there need CE marking (or CE plus UKNI in specific cases), while EU projects require CE only. The practical question for a project buyer is therefore not “which mark is legally newer” but which mark your building control body, warranty provider and specification actually call for — and whether the Chinese factory’s test documentation genuinely supports the mark printed on the product.
UKCA vs CE: What Changed After Brexit
Before Brexit, one CE mark under the EU Construction Products Regulation (CPR) covered the whole of the UK and the EU. After the transition period, Great Britain adopted its own framework — the Construction Products Regulation as retained in GB law — with UKCA (UK Conformity Assessed) as its marking, UK “designated standards” in place of EU harmonised standards, and UK Approved Bodies in place of EU Notified Bodies.
In practice, the two systems remain nearly mirror images. The designated standards for windows, doors, glass, cladding and most other construction products are technically identical to their EN harmonised equivalents — EN 14351-1 for external windows and doorsets, EN 14449 for laminated glass, EN 1090 for structural steel and aluminium components. What changed is who is allowed to certify: a UKCA mark requires assessment by a UK Approved Body where third-party involvement is required, while a CE mark requires an EU Notified Body. For a building material sourcing agent managing orders from China, that distinction determines which test reports and certificates the factory must hold, and from whom.
Key Facts: UKCA and CE for Construction Products
- Great Britain (England, Scotland, Wales): UKCA applies, but CE marking remains recognised for construction products with no announced cut-off date — either mark is currently acceptable.
- Northern Ireland: EU rules apply under the Windsor Framework — CE marking is required; UKCA alone is not valid.
- EU-27 projects: CE marking only — UKCA has no legal standing in the EU.
- Standards: UK designated standards are technically identical to EN harmonised standards for almost all building products, so one set of factory testing can support both marks.
- Certification bodies: UKCA requires a UK Approved Body; CE requires an EU Notified Body — a factory serving both markets needs relationships with both, or a body accredited on both registers.
Can a Chinese Factory Hold Both UKCA and CE?
Yes, and the better export-oriented factories already do. Because the underlying test methods are the same, a window or door factory that has completed initial type testing to EN 14351-1 can have the results assessed by an EU Notified Body for CE and a UK Approved Body for UKCA, then issue two Declarations of Performance — one referencing the designated standard, one referencing the harmonised standard. The additional cost is mostly administrative rather than a full re-test.
The risk for buyers is that many factories claim both marks while holding documentation for only one — or for neither. A CE certificate issued by a body that was struck off after Brexit, a Declaration of Performance that references the wrong standard edition, or a test report for a different profile series than the one you are actually buying are all common findings when a china sourcing agent audits certification files before an order is placed. This is the same verification discipline we apply to CE marking for doors and windows from China — the paperwork is checked against the actual product specification, not taken at face value.
Which Mark Should Your Project Specify?
For a development in England, Scotland or Wales, the pragmatic answer today is CE, UKCA, or both — building control and NHBC-type warranty providers accept either for construction products while CE recognition continues. If your project documentation was written by a UK consultant after 2021, it may explicitly call for UKCA; if it derives from an EU-market specification, it will say CE. Follow the specification, and where it is silent, ask your approved inspector before the order is confirmed rather than after the container lands.
For mixed-destination procurement — a developer shipping the same Chinese window system to a UK project and an Irish or EU project — specify dual marking at the quotation stage. Retrofitting a UKCA or CE assessment after production is slower and more expensive than building it into the order, because the marking must be applied at the factory along with the correct labelling and accompanying Declaration of Performance.
What Documents Should You Collect Before Shipment?
Whichever mark applies, the file your building material sourcing agent should hand you before the balance payment is released contains the same four elements: the Declaration of Performance (DoP) naming the exact product, its intended use and its declared performance characteristics; the initial type test report from an accredited laboratory; the certificate from the Notified Body or Approved Body where the product’s conformity system requires one; and evidence of factory production control (FPC) — the factory’s internal quality system that keeps series production consistent with the tested type. For windows and doors this sits alongside the routine commercial QC that any project order needs — dimension checks against shop drawings, finish inspection and operation testing — which we cover in our guide to certifications to ask for when importing building materials from China.

How Marking Requirements Differ by Product Category
Not every building product needs third-party certification to carry a mark. The CPR (in both its EU and GB versions) assigns each product family an Assessment and Verification of Constancy of Performance (AVCP) system from 1+ (most demanding, full third-party certification and audit testing) down to 4 (manufacturer self-declaration). External windows and pedestrian doorsets sit in System 3 — third-party initial type testing, but no ongoing certificate. Structural components under EN 1090 sit in System 2+, requiring certified factory production control. Fire-rated doorsets and fire-resistant glazing sit in System 1, where a certification body must approve the product and audit the factory continuously.
This matters at sourcing stage because it defines what evidence can exist. If a Chinese factory shows you a “CE certificate” for a System 3 window, the document that actually matters is the Notified Body test report plus the factory’s own DoP — there is no such thing as a blanket CE certificate for that product family, and a sourcing agent who knows the AVCP systems will spot a decorative certificate immediately. For fire-rated products, by contrast, a genuine System 1 certificate with a current audit trail is non-negotiable, and its absence should end the discussion with that factory.
UKCA and CE are only the UK and EU pieces of the puzzle — Gulf and other destination markets run their own conformity regimes. Our guide to SABER, CE and other certifications for school and hospital projects maps what each market expects before customs clearance.
Timeline and Cost Implications for Your Order
If the factory already holds valid test reports with the right bodies, dual UKCA/CE documentation adds days, not weeks, to an order — the work is assembling DoPs and labelling correctly. If new initial type testing is needed — a new profile system, a larger size range than previously tested, or a factory whose certificates have lapsed — allow 6–10 weeks and factor the laboratory cost into the unit price negotiation before production starts. On aluminium window and door packages we source from Guangdong, certification verification runs in parallel with sample approval, so the compliance file is closed before mass production begins rather than while the goods sit packed waiting for a vessel. You can see how demand for compliant product has grown in our review of aluminum windows and doors import data.
The official scope, transition arrangements and current guidance for Great Britain are published in the UK government’s construction products regulation guidance — worth bookmarking, because the CE recognition position is government policy rather than statute and can change with notice.
