As of 10th June 21, this is unclear; DLUHC is working on a solution but has yet to make a decision.
As things stand, while the Government is encouraging mutual recognition in principle and the BBA would like to be able to accept existing EU NB test reports towards supporting UKCA marking, this is not allowed.
At present, duplicate testing will be necessary; we await DLUHC’s final decision.
PLEASE NOTE: This is correct at the time of publishing and may have changed. Contact the BBA for further updates before proceeding with any decisions.
