Allume Energy today announces the completion of its latest investment round, totalling £5 million.

The round was led by E.ON UK, whose £4 million investment and strategic partnership will support the growth plans of Allume’s SolShare technology, which breaks down the technical and ownership barriers that have historically prevented people living in flats from accessing free, clean energy from the sun.


Globally, E.ON is a major provider of energy solutions and clean energy networks with around 47 million customers across 17 countries. In the UK, they serve nearly one in seven households and businesses, and are the UK's largest supplier of electricity to industrial clients.

E.ON’s strategic investment will help Allume to grow its presence in the UK, while contributing to E.ON’s aim to deliver the transition to clean energy. 

Allume's CEO, Cameron Knox commented on the partnership;  “People living in flats experience the highest fuel poverty rates in the UK, yet have historically been locked out of rooftop solar due to technical and ownership considerations. SolShare enables them to access free, clean energy from the sun.

Working with E.ON UK offers a transformational opportunity for Allume to scale our existing offerings and create new models across Europe, where 300 million people live in low and medium rise apartment buildings.”
