Uswitch Special Commendations
Choosing a green energy tariff is only part of becoming more sustainable; how we use energy at home matters too. There are many ways we can improve that, and energy suppliers have started helping their customers on that journey.
This is why Uswitch Energy Accreditation is expanding to include Special Commendations in categories that the Accreditation Panel sees as most valuable at the moment for the energy transition.
Renewable Gas Commendation
100Green has been recognised by the panel with a commendation for its continued commitment to 100% renewable gas.
In a market where green gas remains a genuine challenge for suppliers, 100Green pushes the boundaries of what green energy supply can look like across the full energy mix for going the extra mile to ensure its customers' energy comes entirely from renewable sources.
Community Champion Commendation
100Green has been awarded a Community Champion commendation for its work in making community energy a reality. 100Green's partnership with Energy Local connects communities with nearby renewable generation while handling regulatory, billing and licensing responsibilities on their behalf.
The Dyffryn Banw project in Powys, for example, allows 68 local households and businesses to buy electricity sourced directly from a local renewable plant, saving up to 11.65p per kWh compared to standard grid rates.
Who sets the tariff levels?
Our independent panel of experts has reviewed the green energy market so you don’t have to.
The panel sets the criteria that tariffs are being assessed against, and will review the criteria annually to ensure it reflects current market conditions. This ensures you can always trust you are choosing a tariff that reflects best practice at the time.
