NAO publishes report on DfE response to raising residential care costs

The National Audit Office (NAO) has published a report examining the Department for Education’s (DfE) approach to addressing challenges encountered by local authorities in securing cost effective and high-quality residential care for children in England—revealing costs nearly doubled to £3.1bn between 2019–20 and 2023–24. The report outlines the profile of looked-after children, detailing the current costs and outcomes associated with the residential care system and explores the factors contributing to rising residential care costs and evaluates how the DfE supports local authorities in fulfilling their statutory duty to house looked-after children. The DfE has initiated reforms including draft legislation introduced in December 2024 to enhance financial oversight of private providers and encourage collective commissioning by local authorities. The report concludes the current system is not delivering value for money, citing a shortage of places for children with complex needs as a key factor driving cost increases.
