Octopus Energy denies it is anti-union as GMB pushes for recognition for workers

GMB, a major UK trade union, is pursuing formal recognition at Octopus Energy, the country’s leading energy supplier. The union plans to submit a proposal for voluntary recognition at the London-headquartered firm, positioning unionization as appropriate for a company with a strong public reputation for ethical business practices and sustainability focus.

Octopus Energy has rejected the assertion that workers lack union representation, stating the company has not received requests from staff for such recognition. A company representative characterized Octopus as an outstanding employer that ranks among the UK’s best places to work and noted that all employees hold shares in the organization. The firm also denied being anti-union, asserting it engages constructively with unions when employees request involvement.

Tony Tanushi, a regional energy officer at GMB, countered that management has shown resistance to unionization efforts. He indicated the union intends to pursue arbitration if the voluntary recognition request is unsuccessful. Tanushi argued that employee share ownership does not substitute for formal union recognition, which would provide workers with genuine input on employment terms and conditions through collective bargaining rights.

The dispute has drawn attention from climate advocacy groups. Greenpeace UK’s head of climate stated that unions and workers are essential to the clean energy transition and that jobs in the renewables sector must be secure, well-paid, and unionized. An Octopus Energy spokesperson responded by suggesting environmental groups should encourage unions to reconsider their positions on fossil fuel development, heat pump deployment, and electric vehicles.

GMB has faced criticism from climate organizations for supporting expanded North Sea fossil fuel drilling and opposing government heat pump rollout programs, which contrasts with Octopus Energy’s renewable energy focus.
