Co-operative Energy was a household electricity and gas supplier that traded under one of the best known names in British retail. It no longer supplies homes. The energy business had not traded since 2019 and no longer had any customers, a position recorded in the Energy Company Obligation final determination report published in February 20231. Anyone arriving at this page looking for a tariff, a phone number or a way to switch has arrived at a brand that has gone quiet.
What remains is a paper trail. Co-operative Energy was acquired by The Mid-Counties Co-operative Limited on 21 October 2010 and became a wholly owned subsidiary, and it began supplying domestic consumers in December 2010. It stopped contracting energy generated from coal fired power stations in February 2016. After a price increase on 1 October 2016 its standard variable tariff was £49 a year more expensive than the Big Six standard variable tariffs.
The name still appears in searches because people remember it, and because the Co-operative movement is still active in energy in a completely different way: community owned generation rather than household supply. The sections below set out what the brand offered, what it cost, what happened to it, and what a household can realistically do now.
What Co-operative Energy offered UK households
The offer was a straightforward domestic dual fuel proposition: electricity and gas to homes, sold on the strength of the Co-operative name and its mutual ownership structure rather than on a technical product. There is no published specification sheet for a supply business, because what a supplier sells is a tariff and a service, not a piece of equipment. What can be said with confidence is what the company did and when.
It was acquired by The Mid-Counties Co-operative Limited on 21 October 2010 and became a wholly owned subsidiary, then started supplying energy to domestic consumers in December 2010. In February 2016 it ceased contracting energy generated from coal fired power stations, a positioning that put it alongside the greener challenger brands of the period. By 2016 it was large enough to be measured against the Big Six: following a 1 October 2016 price increase, its standard variable tariff was £49 a year more expensive than Big Six standard variable tariffs.
That last figure is the one that matters most for a household reading this now. A challenger brand's main selling point is usually price, and once its standard variable tariff sat above the largest suppliers, the reason to be with it weakened. The brand's later history is covered in the wider picture of challenger and small energy suppliers and of energy supplier failures.

Specifications: what a supplier actually sells

A supply business has no efficiency rating, output or warranty in the way a boiler does. Its measurable attributes are its fuel sourcing, its tariff structure and its obligations under government schemes. On fuel sourcing, Co-operative Energy stopped contracting coal fired generation in February 2016. On obligations, the numbers are less flattering.
Under the Energy Company Obligation, Co-operative Energy carried an obligation of £56.1m and delivered a lifetime bill saving of £20.4m1. It achieved 36.4% of its obligation by 31 March 2022, and was found non-compliant on that basis1. Its performance against the sub-obligations was lower still: 30.6% against the rural sub-obligation and 23.1% against the social and vulnerable sub-obligation1. The same determination records that the supplier would deliver approximately an additional £3.5m in lifetime bill savings on top of its outstanding obligation1.
For a household, the practical reading is that the Energy Company Obligation is the mechanism through which suppliers fund insulation and heating improvements in homes, and a supplier that under-delivers on it is not delivering the wider benefit that the scheme exists to produce. The scheme itself, which helps to make homes more energy efficient by installing improvements free of charge to eligible households, is described on the ECO4 Flex page for South Cambridgeshire and in the general material on green energy tariffs.
| Attribute | Co-operative Energy |
|---|---|
| Obligation under ECO | £56.1m1 |
| Lifetime bill saving delivered | £20.4m1 |
| Obligation achieved by 31 March 2022 | 36.4%1 |
| Rural sub-obligation achieved | 30.6%1 |
| Social and vulnerable sub-obligation achieved | 23.1%1 |
| Additional lifetime saving committed | approximately £3.5m1 |
Warranty and guarantees: what a supplier promises
There is no product warranty on an energy supply contract. What a household gets instead is a set of guaranteed standards of performance, a complaints process and, if a dispute cannot be settled, access to the Energy Ombudsman. Those protections attach to the supplier that holds the licence, not to the brand name on the bill, which is why the identity of the company behind a brand matters more than the name itself.
The Energy Ombudsman publishes a list of the companies it covers, and that list is a useful check on whether a supplier is real and active. The entries include Energy Optimise Service, which is active and carries the reference C35ENER1482, Energy Swap3, Connekt Energy4, Atlas Energy5, Orbit Energy Limited6, Corus7, Business Energy Online Limited8, LT Energy Consultants Ltd9, Direct Energy Utilities10, Smart Energy & Powwer Limited11, Go Compare Energy Ltd12, SAA Energy Solutions Ltd13, Energy On Solutions Limited14, Vectis Community Energy15, Ecowise Utilities Limited16, Well Known Energy Services Ltd17 and Simply B Energy Ltd18. All are recorded as active.
Co-operative Energy does not appear on that current list, which is consistent with a business that stopped trading in 2019. For a household with an unresolved dispute, the route is set out in the material on complaining about an energy supplier and on the Energy Ombudsman. The Ombudsman's own advice for consumers worried about bills is a starting point for anyone in difficulty19.
What Co-operative Energy cost

The pricing record is thin, and that is itself informative. The one firm figure in the public record is comparative: after the 1 October 2016 price increase, the standard variable tariff was £49 a year more expensive than Big Six standard variable tariffs. That is a statement about position in the market rather than a price list, and it is the last clear pricing marker before the business wound down.
There is no published Co-operative Energy tariff to quote today, because there is no live supply business. Any figure offered for a Co-operative Energy bill now would be invented. For households trying to understand what supply costs in general, the useful comparisons are between live suppliers, and the material on UK energy suppliers and on energy supplier market share sets out who is actually selling to homes.
The wider point about cost is that a supplier's headline tariff is only part of what a household pays. Standing charges, exit fees on fixed terms, and the treatment of credit balances all shape the real cost, and those terms sit with the licence holder. Where a brand is a white label, the terms are set by the company behind it, which is covered in white label energy brands and who owns which energy supplier.
The company's status: stopped trading, no customers
This is the section that answers the search. Co-operative Energy's energy business had not traded since 2019 and no longer had any customers1. That is the finding of the Energy Company Obligation final determination report published in February 2023, and it is the clearest official statement of the brand's position.
The same report records the compliance failure that followed: the supplier achieved 36.4% of its obligation by 31 March 2022 and was found non-compliant1. A supplier that has stopped trading and holds no customers can still carry an outstanding obligation, and that is what happened here. The determination notes that the supplier would deliver approximately an additional £3.5m in lifetime bill savings on top of its outstanding obligation1.
For a household, three practical consequences follow. First, there is no Co-operative Energy tariff to switch to, and any site offering one is out of date or selling something else. Second, an old account or credit balance is a matter for whichever supplier took on the supply afterwards, and the general process is described in final bills and credit refunds and in credit refund after supplier failure. Third, the protections that would normally apply, including the supplier of last resort arrangements, are designed for a live failure with customers to move, which is not the shape this one took.
What it means for household energy independence

A supply brand, however it is owned, does not make a household independent of anything. It sits between the home and the wholesale market, and the home remains connected to the grid, to a gas network and to a supplier's billing system. Co-operative Energy's mutual ownership changed who profited from the margin, not where the electrons and the gas came from. When the business stopped trading, the household's position was unchanged in every respect except the name on the bill.
The genuine independence question is a different one, and it is about generation and heat rather than supply. Community ownership of renewable generation is active and funded: the Community and Renewable Energy Scheme provides advice and funding to communities across Scotland looking to develop renewable energy, heat decarbonisation and energy efficiency projects, including shared ownership projects, and it encourages community ownership of renewable energy projects across Scotland, helping to maximise the benefits of renewable energy systems and ensuring that the delivery of community energy comes with benefits for people in Scotland20. That is a route to local generation, not to a household tariff.
Behind the meter, the picture is similar. Guidance on behind meter energy systems in Wales covers what households can install on their own property21, and the Scottish consultation analysis on energy efficiency standards for owner occupied homes found agreement levels were particularly high among organisations at 90%, although views were more mixed among individuals at 46%22. The direction of policy is towards the fabric of the home and its own generation, not towards the brand of the supplier.
The honest summary is that Co-operative Energy is a reminder that supplier branding is the least durable part of the energy system. The parts that last are the connection, the building and whatever generation sits on the roof or in the garden. Households wanting to reduce dependence are better served by looking at energy suppliers and household energy independence than at a name that stopped trading in 2019.
