"How will you ensure local housing authorities, landlords and tenants are prepared?
Digital UK will contact local authorities, housing associations and landlords of properties with communal TV systems to ensure they are aware of the need to prepare for switchover. Tenants should contact their private landlords to make sure the aerials in their homes or Flats are set for digital.
