Serco runs public services for governments, from prisons and immigration centres to trains, hospitals, and defence support.
Serco is a company that governments hire to do their everyday work. When a government wants to run a prison, staff an immigration detention centre, operate a railway, or keep hospitals and military bases running smoothly, it can either do that itself or pay Serco to do it. Serco is the contractor that steps in and handles the people, the operations, and the day-to-day grind.
The business is built on long-term contracts, mostly with governments in the UK, Europe, the Middle East, and Asia-Pacific. That includes running justice and immigration services, providing transport operations, supporting defence and health services, and managing facilities like cleaning, maintenance, and security. Governments choose Serco because it can bring in specialist staff and operating know-how quickly, and because it takes on the messy operational risk so the public body doesn't have to. Serco has had a bumpy reputation. It has been criticised over the quality of some services and faced serious problems in the past with contracts that went badly wrong, including a scandal over tagging equipment that led to a costly settlement and a government ban from new work for a period. These days it is watched closely on contract performance, because its entire business depends on governments trusting it enough to keep handing over essential services.
The money comes from those contracts: governments pay Serco for running the service, and Serco keeps a margin on top of its costs. It is a steady, low-margin, high-volume kind of business, so profits depend heavily on winning contracts, keeping costs under control, and delivering well enough to win renewals. Its annual revenue runs into the billions of pounds, and investors follow it because it pays dividends and offers a way to bet on government outsourcing.
