DHL receives financial remuneration for operating NHS Supply Chain in the form of a transaction fee for every item ordered.DHL has a significant incentive to maximise sales volume by lowering selling prices and investing in increasing capacity, improving product quality and service performance. There are significant contractual constraints on the maximum remuneration payable including a profit cap. Therefore savings flow through to national health service trusts which in turn ensures benefit to NHS patients by reducing the overall cost of patient care.The NHS Business Services Authority manages the outsourced DHL contract to run the business now known as NHS Supply Chain, ensuring compliance with all contractual obligations.
