“The EU's General Product Safety Regulation 2023/988 replaced the UK's General Product Safety Regulations 2005 across the whole of the UK on 13 December 2024.”

Source 1 states the 2023/988 replacement of the 2005 Regulations occurred only in Northern Ireland, not across the whole UK. The same page is titled 'General product safety regulations: Great Britain' and explicitly 'Applies to England, Scotland and Wales', meaning GB continues under the 2005 Regulations. The claim's 'whole of the UK' scope is directly contradicted by the gov.uk source, the better authority here since it is the primary regulator's guidance page.
