Intertek Group plc (LSE: ITRK) is a global inspection, product testing and certification company headquartered in London, United Kingdom. It is the largest tester of consumer goods in the world and has a network of more than 1,000 laboratories in over 100 countries.

It is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.

The Company can trace its origins from a marine surveying business formed by Caleb Brett in the 1890s, a testing laboratory formed by Milton Hersey in Montreal in 1888 and a lamp testing centre established by Thomas Edison in 1896. These businesses were all acquired by Inchcape during the 1980s and early 1990s. In 1996 Inchcape Testing Services was acquired by Charterhouse Development Capital and was renamed Intertek. The Company was divested by Charterhouse in 2002 when the business was first listed on the London Stock Exchange. In April 2010, Intertek acquired Ciba Expert Services’ Environmental, Safety, & Testing and Regulatory businesses, including Cantox Health Sciences (Cantox) and Ashuren Health Sciences (Ashuren).
