The nine eligible suppliers – the major six companies, as well as First Utility, Utility Warehouse and now The Co-operative Energy – have collectively met 93 per cent of the Home Heating Cost Reduction Obligation (HHCRO) – also known as Affordable Warmth.
Both British Gas and Scottish Power achieved more than their target by the end of June, hitting 106 per cent an 109 per cent of their obligations respectively.
Npower (97 per cent), EDF Energy (97 per cent), and Eon (89 per cent) are also close to hitting their obligation, while Eon has met 66 per cent, and First Utility 18 per cent.
Scottish Power (51 per cent) and Eon (50 per cent) have also made good progress towards their Carbon Emissions Reduction Obligation (Cero).
The other major suppliers (SSE, Npower, EDF, and British Gas) have achieved 33 per cent, 43 per cent, 36 per cent, and 40 per cent of their obligations respectively.
First Utility has met 18 per cent of its Cero obligation at the end of June.
The suppliers are further behind their Carbon Saving Community Obligation (CSCO), with Eco 59 per cent through its first three phases (1 January 2013 to 31 March 2015).
Eon and SSE are the closest to their targets, having achieved 50 per cent and 51 per cent respectively, while British gas (32 per cent), Scottish Power (32 per cent), Npower (27 per cent) and EDF Energy (14 per cent) are further behind.
Utility Warehouse and First Utility have met 0 per cent of their CSCO target.
The Co-operative Energy, which crossed the Eco eligibility threshold of 250,000 connections earlier this year, has yet to make inroads into its HHCRO, CSCO or Cero obligations.
