Immigration Act 2014
The Immigration Act 2014 requires private sector landlords to check the immigration status of their tenants under the Right to Rent Scheme. The scheme went nationwide on February 1st 2016 after being trialed in the North of England from 1st December 2014 in Birmingham, Walsall, Sandwell, Dudley and Wolverhampton.
The aim of the scheme is to prevent those with no rights to be in the UK from accessing PRS housing. An overview of tenant immigration checks can be read here.
