Green fixed energy
Fix your prices until May 2020. We’ll plant a tree for each fuel you get from us. Plus we’ll match all of the electricity and 15% of the gas you use with energy generated from renewable sources then feed the same amount back into the network. Are there environmental benefits?
Are there environmental benefits?
We’ll match all of the electricity and 15% of the gas you use, depending on which fuels you get from us. We do this by purchasing the same amount of energy produced from renewable sources, and feeding this back in to the network.
Plus, when you start using gas or electricity on this tariff, we’ll work with Trees for Cities to plant a tree in the UK to help bring environmental benefits to local communities. So if you buy both your gas and electricity on this tariff two trees will be planted.
Additionality
When green tariffs offer additional benefits to the environment – like lower carbon emissions or donations to an environmental charity we call this ‘additionality’.
Through our work with Trees for Cities this tariff offers additional benefits to the environment. And, we’ll be putting renewable energy back into the grid for the energy you use, which makes it greener than our other tariffs.
Close dialog windowHow does it work?
It’s simple. If the price of fuels on our Standard Variable Rates goes down, then we promise we’ll bring down your prices on this tariff too.
So, you really get the best of both worlds. More certainty with protection from any price rises and the reassurance from knowing that you won’t miss out on price reductions.
Close dialog windowDirect Debit discount
We’ll reduce your daily standing charge so that over a year you'll get £40 off your electricity and £50 off your gas charges for paying by Direct Debit.
If you stop paying by Direct Debit, you'll move on to the Receipt of Bill version of your tariff, with no discount. But we’ll let you know if this happens. Subject to change.
