Our History

William King’s origins can be traced back to the 1820s when it was an ironmonger business, Edmund Boughton and Co, in Gloucester, UK.

The company continued to expand during the 19th Century to include iron and steel warehousing, trading and tinplate production with operations in Gloucester, Birmingham and South Wales.

Jump forward to 1905 and Mr William King purchased the Birmingham operation of Edmund Boughton and Co. Unfortunately, the owner died in 1917 and the business was acquired by Henry William Worley, the grandfather of the current Chairman Michael Worley, and great-grandfather of the current Managing Director Rachel Graville.

A lot has changed over those 200 years, so to get a closer look at how the company evolved, take a tour of our interactive timeline that highlights some of the key dates and milestones in our history.
