Equinor Warns UK Could Become 'Uninvestable' Over Delays to Rosebank and Jackdaw Oilfields

Norwegian energy giant Equinor has issued a stark warning that the United Kingdom could be deemed "uninvestable" if the government blocks final approval for two major North Sea oil and gas developments. Anders Opedal, chief executive of the state-backed company, said the firm would be forced to reconsider its long-term commitment to the UK should ministers reject plans to extract fossil fuels from the Rosebank and Jackdaw fields.

In an interview with the BBC, Opedal described the current uncertainty surrounding the projects as "an uncomfortable position to be in." He acknowledged that a decision against the developments would compel Equinor to "take a hard view" about whether future investment in British energy infrastructure remains viable. "The question will be: is the UK investable in the future? I hope it will not come to that," he said.

The warning comes at a pivotal moment, as the UK government prepares to rule on whether to grant final approval for the two sites. Both projects had initially received the green light from the previous Conservative administration, but their progress was halted by a Scottish court ruling. Environmental campaigners successfully argued that consent had been granted without sufficient consideration of the developments' impact on the climate.

A public consultation on the future of Rosebank and Jackdaw concluded in August, leaving the final decision in the hands of Energy Secretary Miatta Fahnbulleh. The government has said it will weigh all relevant evidence, including environmental assessments and representations made during the consultation, before reaching a conclusion.

Opedal struck a cautiously optimistic tone, expressing confidence that Prime Minister Andy Burnham's stated commitment to a "pragmatic approach to oil and gas" would result in both projects being approved. However, he stressed that the industry required certainty to attract investment. He also argued that the UK is capable of producing more of its own energy resources, describing the situation as "a political choice" rather than a geological or technical limitation.

The Equinor chief pointed to the shared geological characteristics between British and Norwegian waters, noting that several oil and gas fields actually straddle the maritime border. He said the North Sea industry had originated on the UK side and that Norway had learned from British expertise, yet the two countries now find themselves on diverging paths when it comes to licensing new exploration.

Rosebank holds particular significance as the largest undeveloped oil and gas field in the United Kingdom. Located in the North Atlantic, approximately 80 miles north-west of the Shetland Islands, it is estimated to contain up to 500 million barrels of oil and gas. Opedal noted that the exploration licence for the site was granted 25 years ago, with the discovery made in 2004 and a final investment decision taken in 2023.

Both Rosebank and Jackdaw are operated by Adura, a joint venture between Equinor and Shell. Aberdeen-based energy firm Ithaca also holds a 20% stake in Rosebank. According to Adura, Jackdaw is "99% complete" and could begin delivering gas to UK homes as early as this winter if approval is granted promptly.

The debate over new drilling has intensified amid rising energy prices and growing concerns about the UK's energy security. Domestic production is forecast to halve by 2035, while the country already depends on Norway for half of its gas supply. The Norwegian government has continued to issue new exploration licences in its own North Sea waters, a contrast that critics say places British industry at a disadvantage.

Opposition to the projects remains fierce. Tessa Khan, executive director of Uplift, an organisation campaigning for the UK to move away from fossil fuel production, argued that new drilling at Rosebank "won't cut our bills" and represented a "bad deal for Britain." She claimed the field is "overwhelmingly oil for export," benefiting Equinor and its part-owner, the Norwegian government, while leaving British households with high energy costs and a shrinking workforce.

Khan also warned that Labour's "climate credibility is on the line," suggesting that approving the fields would undermine the party's environmental commitments. The controversy is particularly sensitive given that Labour's election manifesto included a pledge to ban new oil and gas licensing, a promise that now appears to be in tension with the government's stated pragmatic approach.

A government spokesperson defended the North Sea as a "vital national asset," insisting that oil and gas would "continue to play an important role in our energy system for decades to come – alongside transitioning to clean power to protect jobs and tackle the climate crisis." The spokesperson reiterated that any decision would consider all relevant evidence, including environmental assessments and public representations.

The outcome carries significant implications not only for Equinor but for the broader investment climate in the UK's energy sector. Industry analysts suggest that a rejection could deter other international operators from committing capital to British projects, particularly as the transition to renewable energy gathers pace. Conversely, approval would likely provoke legal challenges from environmental groups and intensify criticism from climate activists.

For now, the government faces a delicate balancing act. It must reconcile its manifesto commitments with the immediate pressures of energy security, economic investment, and job preservation in Scotland's north-east. The decision on Rosebank and Jackdaw will serve as a litmus test for how the UK navigates the increasingly contested terrain between fossil fuel dependence and climate ambition.

Equinor's warning underscores the high stakes involved. If the UK is perceived as an unreliable or hostile environment for oil and gas investment, companies may redirect their capital to more favourable jurisdictions, potentially accelerating the decline of domestic production and deepening reliance on imports. Whether ministers can square that circle without alienating either industry or environmentalists remains to be seen.
