UKCA UK Conformity Assessed

UKCA stands for “UK Conformity Assessed”. Due to the UK leaving the EU, a new UK product marking regulation will be used in place of the CE mark for goods being placed on the UK market. It is the British version of the European Union’s CE marking. CE, as well as the UKCA mark, are not quality indicators or certification marks. UKCA marking is a similar provision as the CE marking, however applicable for UK laws and the UK market. It must be considered as an implicit declaration from the manufacturer that this product complies with all UK laws and the applicable British conformity assessment procedures.
