Quick Answer
UKCA (UK Conformity Assessed) marking replaced CE marking for construction steel products placed on the Great Britain market from 1 July 2025. Compliant steel mill test certificates must reference the applicable UK-adopted standard, name a UKAS-approved body with its UK(AB) number, and include or reference a UK Declaration of Performance (UK DoP). CE marking remains valid in Northern Ireland and the EU.
UKCA is the UK's post-Brexit product conformity marking system, administered by the Office for Product Safety and Standards (OPSS). For steel, it applies to products that are permanently incorporated into construction works. This page is a compliance guide.
