 Founded in Liverpool in 1865, Costain is one of the UK’s leading engineering solutions providers.

The company operates within the energy, water and transportation sectors and delivers innovative, efficient and value-driven solutions to all its clients.

Costain is Listed on the London Stock Exchange, with a reported turnover of £1.1 billion (for the financial year ending December 2014). The company employs more than 3,300 employees and operates across a broad range of industries, from services, highways and rail, to water, power, oil and gas.

Over the past 150 years, Costain has clocked up some notable achievements including a lead role in developing Next Generation Carbon Capture Technology – capable of reducing CO₂ emissions by 95% – and the construction of the nuclear processing facility at Magnox’s Bradwell site for the dissolution of historic nuclear waste. Costain has also seen a period of eight years without a reportable lost time accident whilst delivering Welsh Water’s Asset Management Period (AMP) 4 and 5 Capital Programmes; and has the only third-party accredited behavioural safety programme in the UK.

Projects for Costain include the Holford Underground Gas Storage project; Reading Station area redevelopment; Paddington Crossrail; the Heysham to M6 link road scheme; and the Peacehaven Wastewater Treatment Works. More recently, Costain delivered a scheme to provide customers in the Hockley area of Birmingham with an alternative supply of water, in the event of an emergency. The project, which completed three months early, was part of a programme of works designed to upgrade a number of existing assets in the area.

Throughout its operations, Costain retains a clear strategy for sustainability; one which places relationships, the environment and the company’s future at the forefront of everything it does. This strategy is known as Costain Cares.

A spokesperson for Costain, said:

“We encourage open, honest and respectful communication. We believe in strong, long-lasting relationships that are mutually beneficial.

“We operate in the built environment, where we meet national needs for strategic investment in infrastructure. We compete in the economic environment, where we must deliver value for customers and shareholders. We have to deliver responsibly to the natural environment for the benefit of everyone.

“We play an important role in the provision of infrastructure vital for the UK economy. The benefits of investment in infrastructure today will be felt for many years to come.”

As well as the high regard that Costain has for its customers, the company also respects and values its suppliers.

A spokesperson for Costain, said:

“Our trade contractors, material suppliers and service providers are integral to our success and customer satisfaction in delivering complex projects and schemes that meet national needs.

“Costain Cares is our vision to build a long-term sustainable business that creates economic, environmental and social value. Our relationship with our supply chain is fundamental to this vision. We are committed to operating a collaborative, sustainable supply chain where our partners support us in delivering efficient, innovative and sustainable solutions.

“We apply scrutiny when procuring products and materials to ensure they are sourced or manufactured in a responsible and sustainable way, from accountable suppliers. Our procurement focuses on both local and UK suppliers. However, it is inevitable that the global market will be a contributor to the numerous components used to deliver our customers’ needs.”
