Faculty worked on the NHS AI Lab's model-validation process for clinical AI—the part of the job that decides whether a model is allowed to matter—and NHS England's deputy director of AI is quoted in the published case. Push Group's health work is visibility rather than clinical: AI agents used to research and structure content for a London obstetrician, which reached first position in Google's AI Overviews ahead of the NHS on a sensitive topic. The AI Consultancy sells to smaller businesses and publishes its rates, which is rare in any sector and rarer in this one. Four more have since joined at the clinical end: Fast Data Science builds named-entity recognition for the NHS and clinical-trial language models for the WHO, Wellcome Trust and Boehringer Ingelheim, Kortical forecasts platelet demand for NHS Blood and Transplant, Datatonic publishes research acceleration with AstraZeneca, and Nebuli worked with Nestlé on vitamin D deficiency. So separate the two purchases before shortlisting. A model that informs care carries validation, information governance and clinical-safety obligations that a content or visibility engagement simply does not. Ask any candidate which of the two they have actually done, and who signed it off. ## Questions buyers ask ### How much do Healthcare AI agencies in London charge?
