Investec sole MLA & bookrunner on £360m AMP Clean Energy debt for Asterion & NWF

  • Follows UK’s National Wealth Fund investment into AMP
  • Investec previously provided a £26 million facility to support AMP’s decarbonization efforts


Investec Bank plc, a leading international financial services provider, today announces that its Energy & Infrastructure Finance - UK & Europe team has successfully advised and arranged a £360 million debt financing for AMP Clean Energy. AMP is a diversified distributed energy company with ~300MW of installed capacity in the UK across heat production, electricity production, and electricity storage. The company is majority owned by Asterion Industrial Partners, a leading mid-market investment manager with c. $10bn AUM.Investec also acted as account bank, security agent, facility agent and global agent on the transaction.

As the Sole Mandated Lead Arranger and Bookrunner, Investec advised on the optimal financing structure and managed the entire process in close collaboration with AMP. It provided an anchor balance sheet commitment and brought in leading infrastructure banks and institutional investors into the financing. The transaction attracted strong market interest  resulting in significant oversubscription.

The comprehensive financing solution underpins AMP’s next phase of growth, which will focus on distributed batteries and innovative heat projects. AMP’s future heat projects will build on the success of AMP’s first of a kind energy centre supplying low carbon heat to Simpsons Malt.

Alongside this, AMP is developing a portfolio of small, distributed batteries, each capable of storing up to four hours of energy—significantly longer than most existing storage solutions. These assets will provide flexible, dispatchable power and play a critical role in supporting the integration of intermittent renewable energy into the UK grid.

The financing builds on Investec’s longstanding relationship with AMP, including facility provided in 2023 to support AMP’s flagship heat decarbonisation project.

Mark Tarry, CEO of AMP Clean Energy, commented: “AMP is committed to creating a smarter energy future by tackling some of the most pressing challenges of the energy transition. This financing package provides the right capital structure to accelerate our growth in distributed batteries and heat projects, which are central to our strategy for decarbonising heat and enabling more renewable energy integration. We are grateful for Investec’s consistent support and partnership as we take this next step in our journey.”

Edouard Picard, Energy and Infrastructure Finance at Investec, said: “We are pleased to have supported AMP Clean Energy with this landmark financing. Our deep understanding of the sector and our longstanding partnership with AMP allowed us to deliver a tailored, scalable structure that positions the company strongly for its next stage of development. This deal showcases Investec’s ability to combine balance sheet commitment with market-leading structuring and distribution capabilities.”
