Exit day is 31st October (this is the date in a Statutory Instrument)
Please remember the UK is bringing in a new UKCA Mark, applicable after Exit day.
The Feb issued instructions on UKCA Mark are here.
This applies to certified goods sold in the UK.
Please follow the links carefully, as some goods will require the UKCA Mark immediately after Exit day.
Other goods will be able to continue with the CE Mark for a limited period.
