This document aims to answer frequently asked questions about the delegation of specialised services from NHS England to Integrated Care Boards (ICBs).

Further information is available from the South London ICBs:

General

A: Specialised services are highly complex, low-volume healthcare services provided to people with rare or complex conditions. These services often require specialised expertise, equipment, and infrastructure. Examples include certain cancer treatments, rare genetic disorders, and complex medical or surgical procedures. They can include renal dialysis and transplantation, complex cancer surgery, chemotherapy and radiotherapy, cardiac surgery, care for patients with sickle cell disease, blood borne virus testing, and most hospital treatment for children.

A: Delegation means that the responsibility for planning and paying for (commissioning) 70 specialised services (approximately £14 billion) is being transferred from NHS England to local ICBs, including South East London ICB and South West London ICB. This allows for greater local input and decision making in the provision of these services.

A: The aim is to improve the integration of specialised services with other local healthcare services, ensuring a more seamless and patient-centred experience. It also allows for decisions to be made closer to the communities they serve.

A: The official transfer of commissioning responsibilities occurred on 1 April 2025.

A: Previously, NHS England directly commissioned specialised services. Under the new system, ICBs have a greater role in planning and shaping these services to meet the specific needs of their local populations.

A: The South London Office of Specialised Services (SLOSS) is a system change catalyst, working with ICBs and providers for a more equitable, efficient, and sustainable future.

Through the delegation of commissioning responsibility to ICBs, SLOSS will continue its mission to underpin specialised transformation with a robust and compelling evidence base to optimise care pathways, reduce inequalities, improve efficiency, and ensure value for money. to provide expertise, coordination, and support to ensure seamless integration and continuity of care.
