We work with companies that are through the start-up phase, demonstrating strong commercial progress and addressing a significant market opportunity.

Arranging funding of £5-60 million, we aim to accelerate growth and maximise potential. Our flexible deal structuring enables us to address the aspirations of management and other shareholders, providing the most appropriate form of capital to each business.

Corran Capital is focused on UK based companies operating nationally and internationally. We target strong financial returns from businesses that also show a commitment to improve their impact on the environment and society.

We currently advise on £140 million of capital from institutional and corporate investors. We have invested in two sector leading renewable energy platforms, Renewco Power and Vital Energi.

It was formed in 2021 by a highly experienced group of entrepreneurs and renewable energy specialists, including partners from Corran Capital. Renewco is expanding rapidly across its range of geographies, with Corran Capital working closely with the business on its growth, strategy and fundraising plans.
