About Us

With a proud heritage, dating back well over 200 years, the name Tennants has stood the test of time.

The original Charles Tennant, a weaver by trade and friend of the famous Scottish poet Robert Burns, patented the process of using lime and chlorine gas to bleach linen in 1788.

Charles Tennant and Co, first registered in Glasgow in 1797, was one of the largest industrial complexes during the industrial revolution, including the famous ‘Tennant Stalk’, a 450 ft. high chimney which dominated the Glasgow landscape.

Due to the importance of linen in Ireland, Charles Tennant first opened an office in Belfast in 1805 and Dublin in 1810 and have been trading continuously ever since.

Charles Tennant & Co (NI) Ltd and Tennants Tar Distillers & Engineering Supplies Ltd were later incorporated in 1945.

Tennants have always sought to add value to trading partners and were involved in the formation of such companies as ICI, Rio Tinto Zinc and Ebano Oil Company (later to become Esso).
