Landlords must check all tenants have the right to legally rent (including any occupants over 18 years who are not named on the tenancy agreement).
Landlords must check the documentary evidence of the tenants’ identity and right to remain in the presence of the tenant. Permitted documents include a passport or biometric residence permit. The checks are detailed and must be recorded.
Fines can be imposed on Landlords who cannot show they checked their right to rent and letting to someone whom they knew or had reasonable cause to know that they did not have the right to rent in the UK could lead to an unlimited fine or a custodial sentence.
