About One Health Group plc

One Health engages 80 NHS Consultants (excluding anaesthetists) who sub-specialise in the various surgeries offered by the Company, through a growing network of community-based outreach clinics and surgical operating locations. One Health continues to deliver strong growth and, in the year, to March 2025 provided much needed care to 17,020 new patients, through over 42,000 consultations and over 7,000 surgical procedures. One Health deploys surgeons and anaesthetists that are mostly employed by the NHS, on a subcontracted basis. It currently works with over 100 professionals across 9 independent hospitals and 37 outreach clinics. Within these community-based outreach clinics all consultations and post operative physiotherapy is delivered where required, reducing patient inconvenience and excess travel.

One Health's activities are focused on areas where NHS patient needs are under-supplied by the local NHS service, population density is relatively high and the level of private medical insurance or the ability to self-fund is relatively low. Currently, the Company's activities are focused in Yorkshire, Lincolnshire, Derbyshire, Nottinghamshire and Leicestershire. Revenue is derived from over 60 NHS commissioning bodies in addition to contracts with local NHS Hospital Trusts to transfer their internal waiting list patients to One Health for quicker treatment.

One Health's business model has focused to date on four main areas: orthopaedics, spine, general surgery and gynaecology, with urology introduced at the end of FY25.

Spine and orthopaedics are particularly attractive areas for One Health as the Directors believe that they benefit from powerful growth drivers in terms of an ageing demographic, physical inactivity and an increasing proportion of the population being categorised as obese. Within orthopaedics, the most common surgeries performed by One Health are knee and hip replacements.
