Choosing a dual fuel energy supplier that was also green used to cost the earth. Thankfully this is rapidly changing. At the time of writing we are one of the cheapest green energy suppliers in the UK offering 100% renewable electricity.
Not surprisingly, most energy suppliers will charge customers a significant premium for green energy. After all, it’s in short supply and typically more expensive to source.


Given the choice wouldn’t we all choose 100% renewable electricity?

We are one of the greenest energy suppliers in the UK. In addition to 100% renewable electricity, we now offer green gas tariffs too. They provide an incremental approach to green energy.
