UK Waiting to See If It Is Adequate . . .

The Brexit transition period ends on December 31, 2020. After the end of the year, the United Kingdom will be considered a third country under the General Data Protection Regulation. In order for data to be transferred from the European Union to the UK, the UK must obtain an adequacy decision from the EU.

Data transfers from the UK to the EU, will not be restricted by the UK. See this post on the main site for Her Majesty's Government. The British government recommends that standard contractual clauses be used to ensure the law transfer of data from the European Union. Templates for SCCs are available in Word documents from the Information Commissioner's Office - an independent regulatory body which reports to Parliament.

The GDPR will continue to be part of British law after the transition period.
