Useful information
We work to a set of standards to make sure we’re always doing the right thing
We’ve got guidelines for everything from handling complaints to being more energy efficient.
Treating customers fairly
We put the customer at the heart of everything we do, and aim to treat everyone fairly. Find out more about the standards we aim for below.
Our fuel mix
These are the fuels we use to generate electricity
All suppliers have to give information about the mix of fuels they use, as well as the environmental impact this has.
This is known as the fuel mix and we publish it every year. The table below shows our fuel mix from 1st April 2019 to 31st March 2020.
