Booth Welsh

Booth Welsh is an employee-owned engineering business. We care about our clients, our people and the impact of our work, with responsible design underpinning our operations.

Founded in 1989, we have grown from our roots in control and instrumentation into a multidisciplinary engineering business. Our services span across the full project lifecycle, from initial concept and FEED through to project execution, ongoing operations and maintenance.

Our capabilities include process engineering, control and automation, electrical and instrumentation, mechanical and piping, civil and structural engineering, project services and digitalisation. By bringing these disciplines together, we help clients solve complex challenges, improve operational performance and deliver safer, more efficient and sustainable outcomes.

We work across highly regulated industries, including energy and renewables, nuclear and defence, life and chemical sciences, food and beverage, and wider manufacturing.

As a purpose-driven and employee-owned business, our people have a direct stake in our long-term success. This strengthens our focus on collaboration, responsible operations and sustainable growth, helping us deliver solutions that create lasting value for our clients, communities and the industries we serve
