A major North Sea gas project is set to begin production, but the benefits for energy security may be greater than the savings on household bills.
Britain's long-running Jackdaw gas field controversy has reached a significant turning point, with the Government approving the project after years of delays, legal challenges and arguments over climate change.
The field, located about 250 kilometres east of Aberdeen, could begin producing gas before Christmas 2026. Supporters see it as an important step towards strengthening Britain's energy security, protecting skilled jobs and making better use of the country's remaining North Sea resources.
But there is a crucial question for households already struggling with the cost of living: will more British gas mean cheaper energy?
The answer is more complicated than the political arguments on either side might suggest.
A project years in the making
Jackdaw has a long history. The field was granted development consent in June 2022, under the previous Conservative Government, following an assessment of its environmental effects.
The project is now operated by Adura, a joint venture involving Shell and Norway's state-controlled energy company Equinor. Its platform is connected to the existing Shearwater infrastructure, allowing gas to be brought ashore at St Fergus in Aberdeenshire.
Using existing infrastructure helps avoid the need to build an entirely separate production and transport system.
However, the original approval did not survive a legal challenge.
In 2024, the UK Supreme Court ruled in the Finch case that environmental assessments for certain fossil fuel developments must consider emissions produced when the extracted fuel is eventually used, not just emissions from extracting it.
Greenpeace subsequently challenged the Jackdaw approval. In January 2025, the Scottish Court of Session ruled that the project's existing consents were no longer valid because the assessment had not properly accounted for the emissions resulting from burning the gas.
The ruling did not mean that Jackdaw could never proceed. It meant that the approval process had to be revisited.
The developers submitted further information and a revised application, followed by another period of consultation. The Government then had to consider the project's environmental implications under the revised requirements.
The latest decision brings this prolonged process towards a conclusion and could allow gas production to begin before the end of 2026.
How much gas will Jackdaw provide?
The developers say Jackdaw could account for around 6% of projected UK North Sea gas production when operating at its expected level. They estimate that its output could provide the equivalent of enough fuel to heat approximately 1.4 million homes.
That is a substantial contribution from a single development, particularly as many older North Sea fields are producing less gas as they mature.
However, the distinction between 6% of North Sea production and 6% of Britain's total gas requirements matters.
The UK relies on a combination of domestic production and imports, including gas arriving by pipeline from Norway and liquefied natural gas shipped from international markets.
The House of Commons Library has estimated that, under optimistic production assumptions, Jackdaw could produce about 10 billion cubic metres of gas over its lifetime. That would be equivalent to around 2% of projected UK gas imports between 2025 and 2050.
These figures measure different things. The 6% figure relates to North Sea production, while the 2% figure compares the project's total potential output with imports accumulated over a much longer period.
Jackdaw will therefore make a useful contribution, but it will not make Britain self-sufficient in gas.
Nor should the equivalent of 1.4 million homes being heated be confused with a guarantee that 1.4 million households will receive cheaper gas. It is a measure of the potential energy content of the production, not a promise about bills.
Will it bring down energy prices?
This is where expectations need to be realistic.
Gas prices in Britain are heavily influenced by the international market. Domestic producers sell into a market affected by global demand, supplies from Norway and elsewhere, liquefied natural gas shipments, storage levels and geopolitical developments.
When international supplies are disrupted, British prices can rise even when the UK continues producing gas of its own.
The war-related disruption to energy markets, tensions affecting shipping routes and uncertainty over supplies from major producing regions all demonstrate how events far beyond the North Sea can influence what British consumers pay.
Jackdaw should reduce the amount of gas Britain would otherwise need to obtain from other sources, assuming its production displaces imports. It could also improve the resilience of domestic supply.
But the additional output is too small to guarantee a substantial reduction in wholesale prices, particularly during an international supply shock.
Household energy bills also include network costs, operating costs, policy charges and taxes, so changes in wholesale gas prices do not translate directly into equivalent changes in what consumers pay.
For households in Caithness and other rural parts of Scotland, the distinction is particularly important. Many properties rely on heating oil rather than mains gas. Even if Jackdaw helps moderate the wholesale gas market, that does not mean heating oil prices will fall by the same amount. Oil prices are influenced by their own international market, refining costs, transport and distribution.
Jackdaw is not a direct solution to the heating costs facing households that have no gas connection.
Jobs, tax revenue and Scotland's energy future
There are nevertheless economic arguments in favour of the project.
North Sea production supports offshore engineering, maintenance, transport, specialist manufacturing and other businesses across Scotland. Keeping existing skills and infrastructure in use may help preserve employment and expertise during the transition towards lower-carbon energy.
The gas will also generate economic activity and potentially tax revenue for the UK Government.
However, the scale of the benefits should not be exaggerated. Jackdaw's construction and development work will not necessarily translate into large numbers of permanent jobs. The project also operates within a mature basin where production from older fields is declining.
For Scotland, the challenge is to ensure that the skills developed through decades of North Sea activity can support a broader energy industry, including offshore wind, electricity networks, carbon management and emerging technologies.
There is also an environmental cost to consider. The gas will produce carbon dioxide when burned, even if the emissions associated with extracting and transporting it are comparatively low. The revised approval process has had to address those wider emissions.
The argument is therefore not simply about whether Britain should produce gas or stop using it overnight. It is about how much domestic production remains useful while the country reduces its dependence on fossil fuels.
A useful contribution, but no energy-price miracle
Jackdaw's approval will be welcomed by those who believe Britain should make full use of its remaining North Sea resources. It offers additional domestic production, supports the offshore supply chain and could reduce the need for imports.
Critics will continue to question whether new fossil fuel developments are consistent with the UK's climate commitments and whether their economic benefits justify the environmental consequences.
Both the economic case and the climate implications deserve scrutiny.
But one conclusion is clear: Jackdaw may help Britain obtain more of its gas at home, but it cannot insulate the country from international energy markets.
For households facing high electricity, gas and heating oil bills, the project is not a substitute for measures that improve energy efficiency, expand reliable low-carbon electricity and protect those struggling with fuel costs.
Jackdaw is a significant North Sea development. It is not a magic switch that will make Britain's energy cheap.
