What drives demand in the industry?

Demographic shifts, particularly an aging population with multi-morbidities, serve as a primary catalyst for long-term clinical demand. In the short to medium term, extensive backlogs in elective surgeries and specialized consultations are accelerating patient diversion to independent operators. Additionally, public sector directives to incorporate remote monitoring and diagnostic analytics are generating considerable demand for digital service layers.

• •A 2026 survey by Healthwatch England revealed that private sector utilization rose to 16% of respondents in 2025, up from 9% in 2023.
