The Westco story began almost forty years ago, when the business opened in 1977 from a small warehouse unit in Oldham, Lancashire.

Quickly developing a reputation for friendly and efficient customer service, Westco soon launched one of its first iconic products; the Cosmos radiator valve, which was the only valve in the industry at the time to offer both wheelhead and lockshield tops.

Over the coming years, the business cemented its position as an innovator, moving with the times and introducing a continuous stream of new, sleekly designed, labour-saving items. One of our most popular product lines, the Westherm thermostatic radiator valve, has been updated many times over the decades, with the latest version, the Westherm 6, proving just as popular and well designed as the very first Westherm, all those years ago.

In 1997 Westco acquired plumbing parts specialist, Dewhurst Distribution. The expansion of our product line and the continuous success of the business led to the decision to move in 2001 to our current 57,000sq ft warehouse and distribution centre in Leigh, Greater Manchester. We swiftly added our own state-of-the art packaging plant for our bagged products and continued to grow; supplying over 5,500 products to more than 3,500 independent and national accounts across the UK and Northern Ireland.

Acquired in 2006 by Dutch industrial specialist, Aalberts Industries, in 2016, Westco became part of French industrial group COMAP.
