Client Overview
Rendesco is a growing UK based energy infrastructure business supporting the transition to a low-carbon economy. With over 90 employees and a Microsoft centric IT estate, Rendesco is committed to leveraging secure, modern technologies that enable efficient operations, strong governance, and compliance with regulatory standards. Their forward-looking approach to digital capability underpins their ambition to scale and innovate responsibly.
Business Challenge
As Rendesco continued to expand and mature its digital capability, the organisation recognised that its needs were evolving beyond what their incumbent provider was structured to support. This wasn’t a reflection of poor service, but rather a natural indication that Rendesco’s pace of growth, security ambitions, and technology roadmap required a partner with broader capability, deeper Microsoft expertise, and a more proactive improvement model.
With increasing demand for stronger identity and access governance, tighter security alignment, and clearer long-term planning, Rendesco sought a partner who could both stabilise day-to-day operations and support a programme of ongoing enhancement. They wanted an approach that would create consistency, strengthen compliance foundations, and provide the strategic guidance needed as the business continued to scale.
