British Solar Renewables obtains £130 million mezzanine capital from Eiffel Investment Group to scale UK and Australia assets

British Solar Renewables has secured a £130 million mezzanine financing facility from Eiffel Investment Group. Backed by 700MW of contracted solar assets, the capital will accelerate the independent power producer’s renewable energy development and construction pipeline across the United Kingdom and Australia.

According to official disclosures, British Solar Renewables (BSR) has secured a £130 million mezzanine financing facility from Eiffel Investment Group. The agreement, backed by approximately 700MW of contracted solar and co-located renewable assets, follows a £345 million project financing completed by the firm in 2025.

BSR, which has evolved into a fully integrated independent power producer capable of managing the entire project lifecycle, will utilize this flexible capital to advance its development and construction pipeline. Eiffel Investment Group, a global asset manager focused on sustainable investments, provides the backing necessary to scale these operations.

This capital injection is strategically significant as it addresses the critical need for long-term funding in the renewable sector. By supporting domestic clean energy generation, the financing directly bolsters the United Kingdom’s ongoing decarbonization efforts and broader energy security objectives. For the renewable energy industry, the deal underscores sustained institutional confidence in the energy transition, demonstrating that well-structured, highly contracted solar assets can successfully attract flexible mezzanine debt.

For investors and market stakeholders, the transaction highlights the viability of the integrated independent power producer model. It signals that developers with end-to-end operational capabilities are well-positioned to capture growing market demand for reliable, homegrown clean power across both the United Kingdom and Australia.
