Shell Energy

The American financial services company will now procure around 150 GWh of clean energy annually

The new tariffs offset CO2 emissions created during customer’s gas and renewable electricity use

The amount is for the costs incurred in acting as a Supplier of Last Resort

The energy supplier will have to make a total payment of £390,000 after charging customers above the price cap

It comes a year after Shell bought First Utility, one of the largest challenger energy suppliers in Britain
