The latest corporate mini-bond from the green supplier will add to the £38 million already raised by the firm through three previous ecobonds since 2010.
Applications for the latest mini-bond close on 30 November and offer Ecotricity customers a 5 per cent return per annum if they invest. Public investors receive 4.5 per cent return per annum.
Ecotricity founder Dale Vince said: “When we launched ecobond one, it was a pretty radical idea, with a simple ambition: to give people the opportunity to share in the financial benefits of the Green Energy revolution.
“And now, to continue our momentum, we’ve launched ecobond four – which will give customers and the wider public the chance to share the benefits of the next phase of our work.”
The mini-bond enables customers and the wider public to invest directly and share the financial benefits of the company.
Earlier this month Ecotricity hiked its energy prices for customers by 5.7 per cent, blaming cost increases from the grid operators and policy from government.
