Our Key People

‘The success we have achieved over the past 80 years owes much to the dedication of the people we have employed.

The drive and determination that characterises today's front line management is reflected throughout all of the Group. All senior management are active participants in the day to day operations and are always available to answer problems and queries.


The availability of senior management ensures that the wishes of all clients and customers are paramount and receive prompt and personal attention.

The investment the Group has made in people and their working environment whether it be in the various company premises or the construction sites throughout the North of England reflect the Group’s commitment to quality in all we build, produce or service.

Given continued reasonable trading conditions the expansion and prosperity of Thomas Armstrong will continue in the years ahead reflecting it’s 180 years history.’
