M&S offer several "100% renewable" tariffs. However, the electricity is supplied entirely from SSE's old hydro schemes - electricity that has been part of the general electricity supply of SSE (and its predecessors NSHEB and Scottish Hydro) for half a century. Rebadging it as M&S and removing it from their general supply doesn't seem to us to do anything to promote higher levels of renewables in the electricity supply mix.
Octopus Energy are a new entrant to the domestic supply market. They have invested in the building of solar farms and we will be assessing their tariffs for inclusion in our listings soon.
Green Electricity Marketplace (GEM) no longer accepts referral fees from electricity suppliers. It is not associated with any general switching site and is committed to promoting renewable electricity through the provision of information and independent assessment of Green electricity tariffs.
We aim to provide accurate and up-to-date pricing, but given the volatility of the electricity market, please confirm current pricing with your chosen supplier.
