The NHS does not lack for AI pitches. What it has lacked is one that keeps patient data inside the country. A British software firm says it now has it.

OneAdvanced, the Birmingham-based SaaS company whose software touches more than 40 million NHS patients a year, has launched what it bills as the UK’s first private, sovereign healthcare large language model trained on NHS primary-care data.

The model, called Care Navigator, was built with Nvidia and trained on pseudonymised, real-world patient triage requests submitted through OneAdvanced’s Patchs online-consultation platform, which handles around 500,000 patient interactions a month.

Its job is triage: detecting the clinical topic in a patient’s request so the system asks the right follow-up questions and routes people to the right care faster, which OneAdvanced says can cut the resource waste that clogs general practice.

The model’s weights, fine-tuning, hosting, and inference sit entirely within the UK, with data stored and governed under UK law, an answer both to NHS rules on data residency and to wider unease about sending health records to US-controlled clouds.
