This notice (formerly a letter) provides information and deadlines on the mandated national adult social care data returns that councils with adult social services responsibilities (CASSRs) are required to complete. This includes important dates for the 2025 to 2026 data returns.
The Department of Health and Social Care (DHSC) has taken over responsibility for these mandated collections. The data should still be submitted through the Strategic Data Collection Service (SDCS) in 2026.
