Thomas Armstrong Group - Leading Construction Company and Manufacturer of High Quality Building Products

Since 1830, Thomas Armstrong Group has become a leading construction company and manufacturer of high-quality building products across the UK.

With rapid expansion and diverse activities Thomas Armstrong Limited underwent a reorganisation and become a Holdings Company in 1964, Thomas Armstrong (Holdings) Ltd. Over the years, subsidiary companies were formed to cover the contracting, timber manufacture, concrete block manufacture and quarrying, haulage and vehicle maintenance activities.


In 1986, the Group moved to its new headquarters on the coast of Flimby, Cumbria where it is still located today. The company has continued to grow and strengthen its position with the acquisitions of various companies and multi-million-pound investments across our block production plants enabling the Group to extend its

geographical operations, which now extend from Glasgow to Congleton (Cheshire) and from Newcastle upon Tyne to Liverpool. The Group’s latest acquisition is Sellite Blocks Limited, a Yorkshire based building block manufacturer in February 2019.


Thomas Armstrong (Holdings) Ltd continues to invest in new technologies and evolve as a company to ensure that it is perfectly positioned to serve the construction industry well into the future.
