Over 400,000 EU Citizens have applied to the Scheme so far.
An estimated 3.4m EEA nationals currently resident in the UK are eligible for the EU Settlement Scheme (based on Home Office internal analysis of ONS Annual Population Survey (APS) data for year October 2017 to September 2018).
The Impact Assessment for the EU Settlement Scheme was published in July 2018
and an updated version was published in March 2019
The Home Office has estimated that the total number of EEA citizens and their family members eligible to apply for the EU Settlement Scheme by the end of the planned implementation period on 31 December 2020 is likely to be between 3.5 million and 4.1 million. This estimate is based on a number of assumptions as to how the size of the eligible EEA population will change over the period. The range should be considered indicative as future migration flows can be affected by many factors and are difficult to predict.
Two reports on the private testing phases have already been published (https://www.gov.uk/government/publications/eu-settlement-scheme-private-beta-1 and https://www.gov.uk/government/publications/eu-settlement-scheme-private-beta-2/eu-settlement-scheme-private-beta-testing-phase-2-report)
