Serco is a giant outsourcing FTSE 100 company operating in the UK, described as ""probably the biggest company you've never heard of."
Areas it operates in include health, defence, nuclear power, transport, prisons, education, aviation and leisure.
Serco health employs over 300 doctors and nurses in primary care and community health services, including out of hours care. Serco also provides facilities management in three NHS hospitals and prison health care.
In May 2012 a Guardian investigation revealed that Serco, which is poised to win much of the new wave of NHS outsourcing contracts, was under investigation by the health regulator, the Care Quality Commission. It had allegedly provided an "unsafe" out-of-hours GP service, and there were claims that it had manipulated results where it failed to meet targets. 
Serco describes itself as 'one of the world's most experienced companies in nuclear safety, technology and management'. Its nuclear Technical Consulting Services (TCS) division supports the operation of over 20 nuclear reactors, and 'serves as the lead nuclear safety advisor to Westinghouse, designer of the AP1000 nuclear reactor currently under assessment for the UK's new civil nuclear programme'. 
It also gives 'independent advice to the Royal Navy on the safety of their nuclear submarines for over 45 years, providing safety documentation, independent peer review, risk management, human factors and occupational safety support'. 
AMEC completed the acquisition in July for GBP 137 million and integrated TCS into its own business during 2012. 
Atomic Weapons Establishment
Serco manages the UK Atomic Weapons Establishment (AWE) as part of a consortium with Lockheed Martin and Jacobs. According to Serco, 'AWE is one of the most advanced research, design and production facilities in the world, developing the sophisticated materials, quantum physics and computer modelling vital to the safe and effective maintenance of the UK's nuclear deterrent. AWE experts also play a leading role in nuclear non-proliferation and international nuclear security'. 
National Nuclear Laboratory
Serco partners with University of Manchester and Battelle to manage the National Nuclear Laboratory (NNL), 'the leading nuclear technology services provider in the UK. NNL has expertise across the full range of nuclear technology, including waste management, nuclear safety and non-proliferation, materials and corrosion and plant inspection.

PR Week reported in November 2010:
- "Outsourcing giant Serco is on the hunt for fresh public affairs support as it seeks to restore its reputation in Westminster following a barrage of negative headlines. Serco... has been attacked for the manner in which it conducts negotiations with suppliers. Last week, the company was forced to apologise for demanding cash rebates from its biggest suppliers in an attempt to help it deliver the Government's cost savings. According to reports, Serco's stance angered Cabinet Office minister Francis Maude because the Government had agreed with Serco that the cuts would come from its own profit margins, rather than those of suppliers and sub-contractors.
- Serco employs Weber Shandwick for lobbying services.  The account is led by Joe Phelan at Weber. Serco previously employed lobbying firm Fleishman-Hillard for a 'specific lobbying issue' until 2010.
- Four Communications also list Serco as a client as of November 2011 on the UK Public Affairs Council register. 
- Serco previously enlisted Weber Shandwick Square Mile for its financial communications work from 2000-2005, though its relationship was on an ad hoc basis according to PR Week until the arrival of Serco director of corporate communications Dominic Cheetham from British Gas in 2004.
