Who is Coop Energy?

Coop Energy, also known as Cooperative Energy, was founded in 2010 as part of the Midcounties Collective.

The supplier absorbed GB Energy in 2016 when it ceased trading, and it later bought Flow Energy in 2018.

Although fairly new as an energy company, the roots of Cooperative Energy go back more than 170 years! The following are some of the more significant dates in the history of the company.

  • 1844: First English Co-op shop opens.
  • Early 1900s: Coop movement spreads across the UK.
  • 2000: Oxford, Swindon and Gloucester Co-op and West Midlands Co-op form.
  • 2005: The two co-ops merge into the Midcounties Cooperative.
  • 2010: Midcounties begins supplying energy nationwide through Co-op Energy.
  • 2016: Coop Energy absorbs GB Energy after the supplier stops trading.
  • 2018: Coop Energy buys Flow Energy.
  • 2019: Cooperative Energy is bought by Octopus Energy, but it continues to trade under the Coop Energy brand name.

Has Coop Energy changed to Octopus?

Cooperative Energy partnered with Octopus Energy in 2019 to supply energy to its customers through what’s called a white-label agreement. In this type of partnership, the latter supplies the actual energy under the Coop Energy brand name.

Coop Energy reviews: What do customers say?

The most recent Coop Energy reviews are overall quite positive. On review site Trustpilot, Cooperative Energy has an average rating of 4.7 out of five stars. Of the more than 3,800 Coop Energy reviews, 77% of customers rated the supplier as either "great" or "excellent".

“Excellent Customer Service, customers are continuously kept up to date, straightforward communication and this at good rates and 100% renewable energy! Brilliant overall package :-)”

LauraTrustpilot review

Seventeen percent of the customers that left reviews gave the supplier a "poor" or "bad" rating. Negative customer reviews were more common before the Octopus takeover. When it came to managing customer accounts and billing, Cooperative Energy didn’t fare particularly well.

“Took months to contact me then sent me a massive bill as their first message, having put me on some ridiculous rate but not giving me any form of contact.”

Coop Energy smart meters

electricity meter

If you have a Coop Energy smart meter, it will continue to work with Octopus’ system. The supplier began its smart meter rollout with the second generation of smart meters (SMETS2), which are interoperable with all energy suppliers.

Cooperative Energy customers who have a smart meter that was installed by a different supplier may find that their smart meter loses its smart functionality with the new supplier. The meter will still continue to work, but your meter readings will not be sent to the supplier. These customers will need to provide monthly meter readings, for which Cooperative Energy will send you regular reminders.

If you don’t already have a Coop Energy smart meter and you would like one, you can contact the supplier to book an installation. With a smart meter, you will no longer need to worry about submitting monthly meter readings, as the smart meter will do this automatically. This also ensures accurate billing.

What tariffs does the supplier offer?

Cooperative Energy offers three different energy tariffs, two of which are fixed-rate tariffs (meaning the rates are guaranteed for the duration of the contract), as well as one variable-rate tariff (in which the rates fluctuate with the wholesale price of energy). The payment method for all three tariffs is monthly direct debit. The supplier does not offer plans for prepayment meter customers.

Since the new partnership was formed, Cooperative Energy no longer charges exit fees to customers who decide to terminate their contract early. This means that customers will not be charged a fee for cancelling and are free to switch a different plan at any time.
