A Guide To 100Green

100Green, formerly known as Green Energy UK (GEUK) is an independent energy supplier, supplying green energy to domestic and business customers in the UK for over 20 years. They are the only company in the UK to supply 100% green gas and renewable electricity.

100Green's goal is to make green energy mainstream and not just an "alternative" for UK customers. To do this they aim to price their tariffs at the same rate as the rest of the local market. Plus, they give shares in their company to current customers as an added bonus.

Their other major selling point is that they prize customer service, even going so far as to offer a customer promise. They operate in England, Scotland and Wales and claim that they are: "the first company in the UK energy market to only supply renewable green gas to its residential and business customers." Thus, making them the only truly 100% green energy supplier in the UK. They are Ofgem (Office of Gas and Electricity Markets) regulated and certified which means your energy supplies are always secure.
