195.This section provides the Secretary of State with the power to prescribe legal requirements imposed on landlords by any enactment, so that if a landlord fails to comply with those requirements, the landlord is prevented from giving a section 21 notice until the landlord has complied with the relevant legal obligation. These requirements include those requirements in relation to the condition of dwellings or their common parts, the health and safety of occupiers of dwellings, and the energy performance of dwellings.
