Andrews will combine her previous client-side experience with the specialist knowledge of the utilities sector which she has gained over the past six years working for Matrix Networks.
The Warrington-based business was founded by Chris Mann in 2006 and now also operates out of offices in Northampton and Slough.
Matrix Networks’ managing director Rob Sparkes, said: “The role of commercial director is a challenging one, but having worked with Wendy for a number of years, I know she fits the bill perfectly.
“She’s not only well qualified for the position but, fundamental to Matrix Networks, Wendy understands our customers and I know she’ll be an asset to our board and the future of our business.”
Andrews, a commercial and legal professional with more than two decades of experience in construction, is the first woman to be appointed to the board.
Matrix Networks specialises in working with the UK’s largest commercial developers and main contractors to complete major multi-utility projects. In the last 12 months alone, it has increased its turnover by 20%.
