Britain has approved the Jackdaw gas field in the North Sea and opened a £2 billion Energy Wealth Fund with a pointed admission: had Westminster treated North Sea revenues as Norway did, Chancellor John Healey says, the country might now possess a sovereign fund worth about £1 trillion. The two announcements, made on 21 October at the St Fergus gas terminal in north-east Scotland, bind an immediate political choice to a much older national regret. Jackdaw will add domestic gas to a system still dependent on Norwegian pipeline supplies and liquefied natural gas.
The new fund, housed inside the existing National Wealth Fund, promises to channel future North Sea tax receipts into Britain’s energy transition. For Norwegian readers, however, the comparison has sharp limits. This is neither a British version of the Government Pension Fund Global nor a replica of the fiscal discipline that underpins it.
It is a £2 billion domestic investment vehicle starting as North Sea output declines, alongside approval for a gas project part-owned by Equinor, the majority state-owned Norwegian energy group.
A late approval for a small field Energy Secretary Miatta Fahnbulleh agreed that the North Sea Transition Authority could grant Jackdaw consent, and the regulator’s chief executive, Stuart Payne, approved it after what the NSTA called robust scrutiny. First gas could arrive by the end of October. Jackdaw sits 150 miles east of Aberdeen. Adura, the 50-50 Shell–Equinor venture that operates the field, will send its gas through the existing Shearwater hub and on to St Fergus. The field was discovered in 2005, but its path to production was interrupted after Lord Ericht of the Court of Session ruled in January 2025 that its earlier consent, alongside Rosebank’s, was unlawful because the climate effects of consuming the fuels had not been adequately assessed. The government says Jackdaw could lift UK domestic gas production by about 6% at its peak, operate for up to 11 years and produce an energy equivalent of 40 million barrels of oil. It cites an Adura estimate of £2.9 billion in economic value, 27 new direct jobs and 273 jobs safeguarded. Those are material gains for the north-east, but their national scale is modest. BBC reporting put the field at roughly 2% of total UK gas demand when imports are included. Fahnbulleh said it would not cut household bills this winter. Gas prices are set in wider international markets, while Britain’s supply mix from 2021 to 2025 averaged 42% from its continental shelf, 37% from Norway and 20% from LNG, according to the government.
“The proceeds of this oil and gas coming ashore now can be invested for the future generations,” Healey said when announcing the fund. Supporters argue that this makes Jackdaw a practical bridge during the transition. Prime Minister Andy Burnham said Britain should consider the responsible use of domestic reserves rather than import all its oil and gas.
Offshore Energies UK called the decision an important step and urged ministers to clear a wider pipeline of projects, including Rosebank. Unite’s Sharon Graham made the labour movement’s case more bluntly: Britain should not let go of one rope before it has grasped another. Environmental groups and some Labour MPs see a different contradiction.
Green leader Zack Polanski called the approval “climate vandalism”; Scottish Greens MSP Ross Greer said it would not lower bills. Their objection is not only to Jackdaw’s limited volume, but to the signal sent by approving new production while presenting climate investment as the destination.
Norway’s model was built differently Healey’s £1 trillion figure comes from unpublished Treasury modelling
reported by the BBC. It assumes around £200 billion of historic UK North Sea receipts had been invested, left untouched and earned returns comparable with Norway’s. The counterfactual is powerful, especially in a week when UK national debt passed £3 trillion, but it requires assumptions Britain never adopted.
North Sea oil was discovered around 1970; the 1980s were the period of peak British receipts, not the beginning of the resource. Norway legislated for its petroleum fund in 1990 and made the first transfer in 1996, roughly 25 years after Norwegian oil first came ashore. Its fund, now valued at NOK 22,014 billion at the end of September, invests abroad.
A fiscal rule allows government spending over time around the expected real return, conventionally 3%, rather than the capital itself. Britain’s Energy Wealth Fund differs in every essential respect. It begins with £2 billion, will invest at home in renewable and low-carbon infrastructure, and is embedded within the National Wealth Fund.
A Treasury source told the BBC the government wanted to learn from Norway’s principle of long-term investment, not copy its model wholesale. That is a sensible distinction, but it weakens the rhetorical force of the £1 trillion claim.
