CHKS was created in 1989 and having developed the UK’s first hospital benchmarking service, grew quickly from its base at the King’s Fund. 

The company moved to new head offices in Alcester in 1991. In 1996 the company acquired Iassist and a year later Caspe Research became part of CHKS. In 2005 CHKS acquired The Health Quality Service, a company specialising in healthcare knowledge management, and the following year it acquired CRC. CHKS, previously owned by Capita are now part of Advanced Advt. They remain one of the leading providers of healthcare intelligence and quality improvement services in the UK, providing support and solutions ranging from online healthcare performance  and governance tools; NHS hospital benchmarking and international accreditation programmes, to bespoke consultancy.
