The Department of Levelling Up, Housing and Communities issued a statement updating its guidance for placing construction products on the Great Britain market. 

This confirmed “the government will continue to recognise the CE mark on construction products for another 2.5 years, to allow businesses until 30 June 2025 to prepare for the UK mark.”

Business Secretary, Grant Shapps announced on 14th November that the deadline for the UKCA mark to become mandatory for most other manufactured goods would be extended to 1st January 2025. BEIS guidance page here

At this stage there is no explanation why the construction products deadline will differ from that for other products.
