In addition, several “white label” suppliers also support the Green Deal.
Ofgem defines a “white label” supplier as an organisation that does not hold a supply licence but instead partners with a licensed supplier to offer gas and electricity using its own branding.
The names of these white label suppliers will be available once we have obtained their consent.
This list is current up until the 1st September 2021. Following this date, the provision of governance arrangements under the Green Deal (previously summarised in the Green Deal Arrangements Agreement (GDAA)) are being transitioned into the Retail Energy Code (REC) from the 1st September 2021. After this date, the GDAA will no longer be active. From the 1st September, any parties with queries should contact the Retail Energy Code here.
