UKCA markingUKCA

A marking declaring that a product meets the applicable European Union legislation; for construction products it means performance has been assessed and declared against a harmonised European standard under the Construction Products Regulation. It is affixed by the manufacturer and supported by a Declaration of Performance and, where required, third-party assessment by a notified body.

The formal document a manufacturer must issue for a construction product covered by a harmonised European standard, declaring the product's essential characteristics and the performance values or classes it achieves. Drawing up a DoP is a legal prerequisite for CE marking under the Construction Products Regulation.

A conformity assessment body designated by an EU member state and notified to the European Commission to carry out the third-party testing, inspection and certification tasks required by EU legislation, including those supporting CE marking. The UK equivalent under the UKCA regime is known as an approved body.

An independent organisation, usually accredited by a national accreditation service, that assesses products, management systems or personnel against standards and issues certificates of conformity. Third-party certification gives specifiers confidence beyond a manufacturer's own declaration of performance.
