UKCA marking

UK Conformity Assessed: the manufacturer declares that the product meets the product rules that apply in Great Britain (England, Scotland and Wales). The UK government’s own guide says UKCA and CE markings demonstrate that the manufacturer believes the product meets the relevant requirements.

A mark tells you what the maker declares, never that the product is safe.

What it looks like: The letters UK above the letters CA, set as a square block. Like CE it must be at least 5 mm high unless a product law sets another size, and scaled in proportion with the government’s templates.
Who may apply it: The manufacturer. For mains electrical equipment the Electrical Equipment (Safety) Regulations 2016 allow every product to be self-declared, so no outside body is required. Until 11 pm on 31 December 2027 the UKCA marking may be put on a label or an accompanying document instead of on the product.

What it does not promise

It is not a government test or approval. It does not replace CE in Great Britain: the UK continues to recognise CE for many product types under the Product Safety and Metrology (Amendment) Regulations 2024, so a charger with CE and no UKCA can be sold there lawfully. Northern Ireland follows a separate process built on CE, sometimes with UKNI.
