According to WYG's chairman, Peter Wood, "The outlook for White Young Green continues to be positive with an order book at record levels and a service offering which continues to expand.
"The strategy of having a broadly based business with no disproportionate dependence on specific sectors of the economy means the Group is well positioned to meet the increasing demands of its growing client base. This resilient business model will enable it to continue to progress and the Board expects to deliver full year results in line with its expectations."
WYG made three acquisitions last year, for a total of £33.1M.
