In 1930, the Boards of Guardians, who had administered the poor relief system in England and Wales since 1834, were abolished and their responsibilities were taken over by county and county borough councils. Each council set up a Public Assistance Committee to oversee its new duties, which included the operation of the various children's establishments previously run by the poor law unions in each area. The Carlisle Council took over the Brackenber Lodge children's home at Shap, formerly run by the Carlisle Union. The home could accommodate up to 63 children.

By 1943, the council had opened a replacemnt home in Carlisle in a property known as Petteril Bank, on Petteril Bank Road, Harraby, where 24 children could be housed.

Following the passing of the 1948 Children Act, councils were required to provide care services for all needy children in their area, especially those who lacked a normal family home. In common with other local authorities, the council established a new Children's Committee, whose responsibilities had previously been spread across separate Health, Education and Public Assistance Committees. The Committee appears not to have retained Petteril Bank (now home to the Carlisle Register Office) but instead opened a new home at Aglionby Grange, Holme Lane, Scotby.

The 1948 Act had recommended that where children needed to be in residential care, they should be in 'family group' homes, which ideally accommodated no more than eight children, or twelve at most. The council's first move in this direction came in around 1953 with the opening of a home for nine children at 16 Portland Square, Carlisle. At around the same time, a further home was opend in a the large premises of Carlisle House, Townhead Road, Dalston.

In around 1961, the Dalston home was replaced family group homes at 1 Meade Road, Harraby, and 30 Raiselands Road, Morton, Carlisle, both located on new council housing estates and each housing nine children. A further family group home was opened in around 1970 at 54 Westrigg Road, Morton.

As part of the local government reorganisation that took place in 1974, Carlisle's social services provision, including its children's residential care, was taken over by the new Cumbria County Council.
