Commenting on the results, Kier Group plc chief executive, Haydn Mursell said:
"I am pleased to report a good set of results showing significant progress on last year and demonstrating the robust operational performance of the business and the benefits of the May Gurney acquisition."
"While the economic climate continues to be positive, operating margins remain challenging due to inflationary increases in the supply chain. Cash generation will continue to be constrained in the short term. However, strong risk management and our ability to offer a greater breadth of service offerings positions us well for the future."
