Control Systems


Control systems have been at the centre of the operations of Henry Williams Limited since our very earliest days, though the nature and application of those systems have changed enormously over the years. The company was formed in 1883 to manufacture control and signalling equipment for the rapidly expanding railways network. In the 1950s the advent of Solid State Electronics moved the field of control systems into new territory, we have continued to set the pace ever since, providing a wide range of systems for the control, monitoring and recording of industrial processes in both the public and private sectors.

In addition to our work in control systems, we also design, manufacture, install and commission a wide range of products for the railways and highways industries, as well as offering a comprehensive forgings service.

Today, we are a versatile and multi-skilled engineering business, based in Darlington in premises occupying almost 10,000 square metres and on a site covering 4 hectares in total. We can call on advanced electrical engineering, forging and fabrication technology, as well as first class design and project management expertise, to meet the ever-advancing control and automation needs of a wide range of market sectors.


Henry Williams Limited has the ability, experience and resources to handle any control systems project from concept to commissioning, taking in all of the following:

  • System design, engineering and procurement
  • Manufacturing, testing and inspection
  • Installation, commissioning and training.

However, we also have the flexibility to step into a project at any stage, according to the customer’s needs.


We manufacture a wide range of off-the-shelf products but can also produce bespoke designs to meet specific customer specifications.

Our diverse experience includes production of all types of control panels from small one-off process control panels and telemetry outstations, to extensive mosaic mimic panels. We can also handle any scale of project, from simple relay logic control systems to highly complex computer based control and information systems.

The fields in which our expertise has been put to use include a wide range of petrochemical, process and heavy industries.


Our products and services have helped many of the biggest names in industry achieve the levels of control and automation they need. Their status and reputation provide us with the best testimonial we could wish for.
