The day-to-day operation of the social housing system, including tenancy agreements, is a matter solely for each local authority. My Department has no role in this regard.
That said, it is typically a condition of social housing tenancy agreements that tenants must inform the relevant local authority of any change in circumstances related to their tenancy, including changes in employment, changes to the make-up of the relevant household, or where members of the household are no longer normally resident in the dwelling. Local authorities may then reassess the rent payable to reflect these changes in circumstances.
