The Intertek story starts at the inception of the modern testing industry. The history of Intertek goes back over 130 years, and evolves from the combined growth of a number of innovative companies.

1880 - 1900

  • Mr. Caleb Brett founds a marine surveying business in the United Kingdom to offer independent testing and certification of ships' cargoes (1885).
  • Mr. Milton Hersey establishes a chemical testing laboratory in Montreal, Quebec, pioneering the idea of independent testing laboratories (1888).
  • Mr. Thomas Edison establishes the Lamp Testing Bureau of his Edison Electric Illuminating Company in America, the origin of the world's electric light industry (1896).
    • The Lamp Testing Bureau is later renamed 'Electrical Testing Laboratories,' and later shortened to 'ETL.'
    • It grows to provide testing to General Electric and other industries being created by new invention at the time, such as air-conditioning, over the next 40 years.


  • SEMKO is founded in Sweden to provide Swedish electrical and electronic product safety testing (1925).
    • SEMKO registers the 'S-Mark.' It becomes a product testing organisation accredited by the Swedish government for its mandatory certification.
    • It further expands to provide certifications for products in wider Nordic markets, and the international electrical and electronic industries over the next 40 years.
  • Mr. Chas Warnock forms the Chas Warnock Company in Montreal, Canada to inspect steel products (1927).


  • Milton Hersey and Chas Warnock merge their companies to create 'Warnock Hersey', one of the largest testing and inspection entities in Canada (1954). The company expands into minerals, lumber testing and the US market.
  • Inchcape, a diverse international group at the time enters the testing industry by establishing 'Labtest' Hong Kong to serve the internal needs of the Dodwell companies, a multinational corporation acquired by Inchcape (1973).
    • Labtest began with just three people – Raymond Kong, Alfred Yung and Thomas Chan.
    • Labtest originally focuses on textile testing, and later broadens across other consumer goods. It is the first commercial consumer goods testing facility in Hong Kong.

  • Inchcape acquires multiple testing and inspection companies, ranging from petroleum, petrochemical, textiles, to electronics and minerals testing (1975- 1980)


  • Inchcape reorganises. It forms a specific testing business stream, 'Inchcape Testing Services' (1987), including Labtest and its other acquisitions in the testing, inspection and certification area.
  • Inchcape acquires the Caleb Brett group of companies, and the government trade and inspection services businesses in the UK ('Foreign Trade Standards') and the US (Intertek Testing Services and Intertek Services International) (1984-87).
  • Labtest acquires the product safety consulting business RAM (Risk Analysis & Management™). RAM supports clients such as McDonalds and their toy safety programme (1988).
  • Inchcape acquires ETL Testing Laboratories (1988).
  • Inchcape continues its acquisitive path, buying Warnock Hersey in North America (1992) and SEMKO in Sweden (1994), and other testing companies. It amasses a range of accreditations and registrations needed to provide certification, inspection and testing services across various industries including automotive, aerospace, electronic and consumer goods.
  • Inchcape's Testing Services division is bought as part of a management buy-out by Charterhouse Development Capital, a global investment company (1996).
