The firm specialises in street lighting, traffic signs and signals, highway technology systems, fibre networks, electric vehicle infrastructure and independent connections.

MSF works regularly alongside civils contractor Octavius Infrastructure which was acquired by RSK last year.

Founded and led by Managing Director Shaun Stacey, MSF employs 175 people across its Northamptonshire headquarters and County Durham office.

It works directly for National Highways as a principal contractor and delivers projects throughout the UK’s strategic road network and wider infrastructure markets. The company also supports many of the UK’s leading civil engineering contractors, including Balfour Beatty, GRAHAM, Esh Group, Costain and Winvic.

RSK Group Chief Executive Officer Alan Ryder said: “MSF is a highly respected business with an outstanding reputation across the UK’s highways and infrastructure sectors. Its specialist expertise complements existing capabilities across RSK and supports greater collaboration throughout the group.

“The company is well positioned to support future investment in National Highways programmes, highway technology upgrades, decarbonisation initiatives and growing demand for electric vehicle charging infrastructure.

“It also brings a significant self-delivery workforce, established client relationships and exceptional accreditation credentials. We are delighted to welcome Shaun and his colleagues to RSK and look forward to supporting the next phase of their growth.”

MSF Managing Director Shaun Stacey, who will continue to lead the business, said: “MSF has built its reputation on technical expertise, a strong safety culture and a commitment to delivering high-quality projects for our clients.

“Joining RSK creates exciting opportunities for growth while allowing us to retain the values, leadership and delivery model that have contributed to our success.

“Our clients will continue working with the same trusted teams, while gaining access to a broader range of expertise and complementary services from across the wider group. We are looking forward to working with our new colleagues and building on the foundations already established within the business.”
