Where does our electricity come from?

It's really simple. Just 1 source: renewables.

As an independent energy supplier our focus has always been on our members, rather than generating our own power. So we buy electricity from the energy market, and then offer it to you at competitive rates.

All of our renewable electricity is backed by renewable electricity certificates.

Here’s what goes into our electricity

We're also asked by Ofgem to tell you what our confirmed fuel mix was in the past - once final figures were calculated. Here's what was in the last reporting period (1 April 2019 to 31 March 2020)
