All licensed electricity suppliers, regardless of their market share, will be obliged to establish, by 1 October 2012, a central charge database to facilitate the collection and remittance of Green Deal payments.
All electricity suppliers with more than 250,000 customers will be obliged to validate Green Deal plans from 14 January 2013 in advance of plans being signed from 28 January 2013, and collect and remit Green Deal payments from 1 March 2013. Electricity suppliers with less than 250,000 customers can choose to take part in the Green Deal charge mechanism by acceding to the Green Deal Arrangements Agreement (GDAA). The drafting of this agreement is currently being finalised and the GDAA will come into operation in due course. Smaller electricity suppliers will only be in a position to indicate whether they will take part in the Green Deal charge mechanism when this agreement is finalised.
