Councils have seen a 53 per cent increase in children on child protection plans in the past decade, while 88 children are now taken into care every day to keep them safe.
In the LGA poll, more than 80 per cent of lead councillors surveyed said problems such as domestic violence, substance misuse and offending were behind rising demand for services in their area, while 70 per cent said that poverty, poor housing and debt played a part.
Nearly two-thirds (64 per cent) said the number of children and young people receiving child protection support or being taken into care has increased “to a great extent” since 2015/16.
The LGA is calling for the next government to fully fund children’s services and invest in preventive services aimed at helping struggling families stay together and thrive.
Cllr Judith Blake, Chair of the LGA’s Children and Young People Board, said: “Councils want to make sure that children can get the best, rather than just get by.
“Yet, funding pressures are coinciding with huge increases in demand for support because of problems like hardship and family conflict, which is making it increasingly difficult for them to do that.”
