**UKCA marking** (UK Conformity Assessed) is the UK's post-EU-exit conformity assessment mark, introduced to replace the [CE mark](/glossary/ce-marking) for products sold into Great Britain (England, Scotland, Wales). Northern Ireland continues to use CE marking under the Windsor Framework arrangements.

## Industrial relevance

Industrial sonic horns destined for British power plants, cement works, [WtE](/glossary/waste-to-energy) facilities and refineries fall under UKCA scope. UK government has repeatedly extended the transitional period during which CE-marked products remain acceptable; current acceptance arrangements should be checked at the time of any specific transaction.
