Co-operative Energy in the news

In 2015, we received many complaints about Co-operative Energy. These included lengthy telephone waits, problems with receiving billing information, passwords not being recognised, difficulty providing online meter readings and emails being ignored. Co-op apologised and said these were linked to its new customer service system, launched in March 2015, that had some 'teething problems'. 

On 18 October 2013, Co-operative Energy announced it would be increasing its gas and electricity prices by an average of 4.5%, applying to new customers from 21 October and to existing customers from January 2014. But on 13 November it said that it would cut that increase to 2.5%, in response to the government's indication that it would remove some of the green taxes from energy bills.

And back in 2012, unlike other suppliers, the Co-operative Energy announced decreases to its prices twice. At the beginning of 2012, Co-operative Energy reduced dual-fuel prices by 5%; and in December it cut electricity prices by 2%.

The Co-operative Energy won the Which? auction in May 2012, when it put forward two market-beating deals. It gained 30,000 customers as a result in the UK’s first collective switch.

The Co-operative Energy was also awarded the Positive Change Award at the Which? Awards 2012.

Which? verdict

This is the largest independent co-operative in the UK, owned by 200,000 customers. Part of The Midcounties Co-operative, its aim is to be transparent and to focus on its customers and long-term sustainability. Some 68% of its electricity comes from renewable sources.

Customers can become Midcounties members for £1 and receive a share in profits. It was the first energy supplier to get a Fair Tax Mark accreditation for its responsible tax.

Pros: Competitive prices, ethical, share of profits for its members

Cons: Its customer score dropped this year
