Co-operative Energy

Co-operative Energy supplies energy nationwide and has no shareholders – Co-operative Energy members get a share of the profits instead.

Co-operative Energy is part of the Midcounties Co-operative. This is the UK’s third largest co-operative, established in 2010, which now has more than 600,000 members. 

Co-operative Energy claims to be an ethical provider and to give its customers a say in how it’s run and from where it buys its energy. It also claims to offer fair and easy to understand energy tariffs.

Co-operative Energy customer score

Co-operative Energy came 20th out of 23 energy companies rated by 8,917 members of the public in the annual Which? customer survey - the biggest of its kind. It was ranked similarly last year by its customers.

To calculate the customer score, we ask customers how satisfied they are with the company and if they would recommend Co-operative Energy to a friend. 

‘As a member of the Co-operative I get a share in the surplus, not private or corporate shareholder controllers'

Which? verdict on Co-operative Energy

Co-operative Energy aims to be transparent and focus on its customers and long-term social sustainability.

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

However, over the past two years, Co-operative Energy's customer satisfaction rating in our survey has been low. In 2016, it paid out compensation to customers who had been let down by its poor complaint resolution, call handling and billing, following an IT failure in 2015. Scroll down to ‘Co-operative Energy in the news’ to find out more.

'It isn't the highest charger, nor the lowest.'

Co-operative Energy customer

One customer told us: ‘It seems to have problems with the website, so it's difficult to resolve problems like making payments.’ Another said the bills ‘could be a lot simpler. Sometimes the timing of the bills makes it look like I've missed a payment or paid an extra month - I have to wait for the next bill to see if it has averaged out’.

But it’s not the lowest-scoring small supplier this year – that’s Extra Energy

Plus, over the least two years we've found big improvements in how quickly it answered the phone to its customers in our snapshot energy customer waiting investigations. Co-operative Energy was the fifth-fastest energy firm to answer the phone to its customer services, in an average of 1m4s. In 2015 it took over 10 minutes to pick up the phone on average.

It was quick to respond to emails too. It took 4h23m on average for us to get a human response to our emails – the second-fastest company to respond. 

In our survey, customers rated its value for money reasonable - but better than its customer service, bills and attempts to help them save energy. As one customer said: ‘it seems quite reasonable’ and another added: ‘It isn't the highest charger, nor the lowest.’

Pros: No shareholders; members get a share of the profits, ethical, answers the phone to its customers and responds to their emails quickly

Cons: Its customer score is low for the second year in a row, after dropping dramatically

Co-operative Energy prices

The graph above shows how Co-operative Energy’s variable (also called standard) tariff and its cheapest fixed tariff compare with the cheapest fixed tariff available on the market over the past year. 

As you can see, Co-operative Energy customers could always save over the last year by picking its cheapest fixed tariff, especially during summer and autumn in 2017. However, its standard tariff was its cheaper option in parts of 2016.

In February 2017, Co-operative Energy announced a 5% average price rise for customers on its standard tariff (called Green Pioneer), from April 1. It says 96,000 customers will be affected by the increase but not those who were formerly GB Energy customers.

It said it had “absorbed a number of rising costs, including network charges and industry obligations” but this is “no longer sustainable and we have reluctantly taken the decision to pass on some of these costs to customers”.

In October 2016, Co-operative Energy also increased its gas and electricity prices by an average of 3%. Prices for those on prepayment meters increased by an average of 6%. 

Co-operative Energy in the news


February: Co-operative Energy announced a 5% average price rise for customers on its standard tariff (called Green Pioneer), from April 1. It says 96,000 customers will be affected by the increase but not those who were formerly GB Energy customers.


November: Co-operative Energy gained 160,000 extra customers after . It was selected to take on the customers by energy market regulator Ofgem, following a competitive tender process. Co-operative Energy said customers would continue to pay the same amount and it would offset any credit built up with GB Energy Supply against future use.

October: Co-operative Energy paid £1.8m to customers let down by its complaints resolution, call handling and billing processes, following regulator Ofgem's announcement on 27 October. It also paid out to energy charity StepChange.

The problems were the result of its new IT system in March 2015 - we reported on this in 2015, after receiving many complaints. These included stories about lengthy telephone waits, problems with receiving billing information, passwords not being recognised, difficulty providing online meter readings and emails being ignored. At the time, Co-operative Energy apologised and said these were linked to its then new customer service system that had some ‘teething problems’. 


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.
