The Housing Agency assisted the National Audit and Oversight Committee in the completion of this review. The review examines the effectiveness of local authorities in managing and maintaining their housing stock, i.e. dwellings that the local authorities either built or purchased for the purpose of providing social housing. It also examines the effectiveness of local authority processes for dealing with repairs requests, planned maintenance, the preparation of vacated units for re-letting, maximising occupancy, combatting anti-social behaviour and managing estates that are predominantly owned by local authorities.
