A green energy supplier has become the fourth company to refuse to take part in Which?'s Big Switch scheme.
According to an article published by the Observer, Ecotricity have refused to involve themselves in the scheme on the basis that Which? are making a significant amount from it - a figure calculated by the green energy supplier as Â£8 million.
Which?'s Big Switch scheme aims to provide customers with the means to get cheap electricity and gas through the power of collective bargaining.
SSE, Ovo and Utilia - representing 18 per cent of the energy market - have already refused to take part in the scheme.
Founder of Ecotricity, Dale Vince, explained: "We feel if they want to become an energy broker, they need to make it clear to the public that this is not a purely charitable campaign and has a definite commercial outcome."
A spokeswoman for Which? confirmed that the company would be charging the winning supplier(s) Â£40 to take part in the scheme.
She also added: "Which? is a not-for-profit organisation, but we have made clear that we hope to cover our costs by charging a fee to the winning supplier, just like all switching sites."
