Under the EU Settlement Scheme, we conduct automated checks of certain tax and benefits records held by HM Revenue & Customs and the Department for Work and Pensions, where the applicant chooses to provide their National Insurance number. The checks help to provide evidence of the applicant’s residence in the UK and remove or reduce the need for them to submit documentary evidence of this.
The business logic of how the checks calculate the period of residence is available on gov.uk at: https://www.gov.uk/guidance/eu-settlement-scheme-uk-tax-and-benefits-records-automated-check
We have also published there the memorandum of understanding with each department, reasons why records may not be found, and guidance on the wide range of other evidence we can use to confirm UK residence.
All applications under the scheme are decided by a caseworker.
