About Us

ORH helps emergency services around the world to optimise resource use and respond in the most effective and efficient way.

We have set the benchmark for emergency service planning, with a proven approach combining rigorous scientific analysis with experienced, insightful consultancy. Our expert team uses sophisticated modelling techniques to identify opportunities for improvement and uncover hidden capacity. Simulating future scenarios ensures that solutions are objective, evidence-based and quantified.

Every organisation faces a unique set of challenges, so remaining independent and flexible allows us to deliver an appropriate solution every time. The outputs of our work enable clients to make robust, data-driven decisions and explain them clearly to stakeholders.

ORH’s approach is always tailored to the needs of the client. Above all, we are committed to getting it right, for the good of our clients and the people who rely on their services.


ORH was established in 1986, but our origins go back to the 1970s and the OR research groups set up by the government to develop and apply modelling techniques within the NHS and local government. From our offices in Reading, England, the company has carried out over 500 reviews for organisations around the world.

ORH is the trading name of Operational Research in Health Limited, a company registered in England with company number 2676859.
