From 1 February 2016 sections 20-37 of the Immigration Act have become effective throughout England... in addition to pilot areas of Birmingham, Dudley, Walsall and Wolverhampton.
It means that a landlord should not authorise an adult to occupy property as their only or main home under a residential tenancy agreement unless the adult is a British citizen, or EEA or Swiss national, or has a “right to rent” in the UK. Within 28 days before the start of a new tenancy, you must make checks for:
a. People aged 18 and over living in your property, whether they are named in the tenancy agreement or not.
b. All types of tenancy agreements, written or oral.
You can be fined up to £3,000 for renting your property to someone who does not have a right to be in the UK.
Landlords have the option to appoint an agent to act on their behalf. Where an agent has accepted responsibility for compliance with the Scheme, the agent will be the liable party instead of a landlord.
