The Immigration Act 2014 was introduced in December 2014. It requires us to check every prospective tenant's "Right-to-Rent" a property in the UK. To allow us to perform these checks, we need you to visit our offices and produce original copies of accepted documents. This needs to be done in person, somebody cannot bring your documents for you, we also cannot accept copies of documents. Failure to produce proof that you are legally allowed to reside in the UK will mean we are not be able to let a property to you.
