CleanTech Wholesale has emerged as a transformative force in the UK energy sector, aiming to empower installers through a technologically advanced supply chain. Formerly known as Callidus Wholesale, the rebrand underscores the company’s commitment to supporting ambitious professionals in the renewable energy industry.
The energy distribution landscape has long been dominated by slow-moving, impersonal corporations. CleanTech Wholesale seeks to disrupt this status quo with an AI-first model and streamlined logistics, directly opposing the inefficiencies that have historically hindered installers. David Martini, Founder and Managing Director of CleanTech Wholesale, stated, “This is more than a name change. It’s a statement of intent. It’s a dynamic mix of technological use and human-centric values. This new approach frees up time that allows us to spend more real-life moments with our partners — the installers.”
CleanTech Wholesale promises to be a competitive advantage for installers aiming to expand their businesses. The company offers a frictionless supply chain through an intelligent platform that reduces wasted time and frustration. Additionally, a curated hub of educational content and cutting-edge technology is available to keep installers ahead of industry trends. The company also emphasises genuine partnership, prioritising human connection and personalised service as opposed to the detached approach of traditional corporations.
Designed for the agile and adaptable installers poised to shape the future of energy, CleanTech Wholesale’s rebrand represents a strategic blueprint for success. Further information can be found at www.cleantechwholesale.co.uk.
