This week, the government published its policy paper for managing the immigration status of EU nationals in the UK after Brexit. The policy paper is still to be negotiated with the EU but it confirms that once the UK has officially withdrawn from the EU (which could happen at any point on or before 29 March 2019), existing residence documents such as those certifying permanent residence, would be invalid. Instead, all EU nationals and their family members would need to apply for new residence documents.
