Swap to Bulb and we both get £50 credit.
They have one tariff for everyone, so no worrying if you are on the best deal. I moved from EON and Bulb were the cheapest in comparison sites. They offer the Warm Home Discount (double check if you change to them because this changes yearly). Their electricity is 100% renewable and their gas 100% carbon neutral.
They say:
“For every unit you use, we make sure a unit is produced and put on the grid by a renewable source including solar, wind and hydro. Plus, our gas is 100% carbon neutral. 10% is green gas produced from renewable sources like food or farm waste. And we offset the rest of the gas we supply by supporting carbon reduction projects around the world.”
