WysePower is delighted to announce that it is now part of the RSK Group, a global leader in the delivery of sustainable solutions.
RSK provides end-to-end, bespoke solutions to various sectors including environmental science, research, engineering, and technical services. WysePower will sit comfortably within the Group, able to capitalise on synergies that exist between the constituent organisations.
This gives us the opportunity to enhance our project work and client relationships by working with a host of RSK businesses from the same or related sectors.

While it is very much business as usual at WysePower, which will continue to operate as an independent organisation, access to the resources and backing of the RSK group will support the company’s ongoing growth strategy.
MD Shawn Callaghan, who will continue to lead the business, said: “For more than 60 years, we have developed and maintained the trust and support of our clients who appreciate the breadth of our service packages, the quality of our designs and installations and the dedication of our employees.
“We look forward to continuing this work, specialising in prestige projects, and emerging market sectors such as high-tech manufacturing, hyperscale data centres and major infrastructure projects while benefitting from the growth RSK can offer. This gives us the opportunity to enhance our project work and client relationships by working with a host of RSK businesses from the same or related sectors.”
RSK Group CEO Alan Ryder said: “I’m pleased to welcome WysePower and their 260 employees into RSK. Temporary site services remain in high demand despite ongoing economic slowdown, and I expect this will only continue. Beyond this, WysePower is a great cultural fit in our group; the ethos and values of the business are very similar to that of the wider RSK so I have no doubt they will settle in quickly.”
RSK comprises of more than 175 companies, employing 10,000 people.
