Amid ongoing volatility in global energy markets, domestic gas production from the North Sea has played a critical role in helping the United Kingdom manage costs and maintain energy security. A recent analysis highlights that locally sourced gas has delivered substantial savings compared to liquefied natural gas (LNG) imports.
This advantage is becoming increasingly significant as global LNG prices face upward pressure due to geopolitical tensions, particularly in the Persian Gulf—one of the world’s key energy supply hubs.
According to the latest analysis, the UK saved approximately £2.5 billion in 2025 by relying on North Sea gas instead of LNG imports. The savings reflect a consistent price gap between domestic production and imported fuel.
Data over recent years shows that LNG has been significantly more expensive. Over the past three years, imported LNG has cost on average 18 pence per therm more than UK North Sea gas.
Looking at a longer period from 2018 to 2025, LNG averaged 91 pence per therm, compared to about 80 pence per therm for UK National Balancing Point (NBP) gas—representing a 13% price premium.
This cost differential has allowed the UK to significantly reduce its overall energy expenses during periods of global price instability.
In 2025, North Sea gas accounted for approximately 45% of the UK’s total gas supply, making it a cornerstone of the country’s energy system.
Pipeline imports from Norway contributed around 35%, while LNG imports made up the remaining 20%. This diversified supply mix helps balance cost efficiency with supply security.
Maintaining a strong share of domestic production not only reduces reliance on volatile global markets but also enhances resilience against potential supply disruptions.
The outlook for global LNG markets suggests continued upward pressure on prices, particularly as geopolitical tensions in the Persian Gulf intensify. Any disruption in this critical region could quickly tighten supply and drive costs higher.
In this context, the cost advantage of North Sea gas becomes even more pronounced. Domestic production provides a buffer against external shocks and limits exposure to international price swings.
However, the future of North Sea gas production depends heavily on government policy, particularly taxation on oil and gas producers.
Analysts suggest that reforming the UK’s windfall tax could help stabilize output in the short term and support growth over the longer term. Previous research indicates that tax reforms could generate an additional £25 billion in revenue by 2035.
This highlights the significant potential of domestic energy resources if supported by a favorable regulatory environment.
Despite aggressive efforts to expand renewable energy, natural gas is expected to remain a key component of the UK’s energy mix for decades.
Projections suggest the UK could consume around 12 billion barrels of oil equivalent by 2050, even under a net-zero emissions scenario. Notably, only about 25% of gas is currently used for electricity generation, with the remainder serving industrial processes and heating.
This indicates that clean energy targets will reduce—but not eliminate—gas demand.
Natural gas also plays a crucial role in supporting renewable energy. As wind and solar output fluctuate with weather conditions, gas-fired power plants provide flexible backup to stabilize the grid.
The UK government estimates that around 35 gigawatts of gas-fired power capacity will still be needed after 2030 to support renewable integration.
Even under a comprehensive net-zero transition scenario, with more than 180 gigawatts of renewable capacity by 2035, annual gas demand could still reach approximately 40 billion cubic meters.
The UK now faces a strategic balancing act: expanding LNG import capacity while maintaining domestic production.
Continuing high taxes on local producers could discourage investment, while overreliance on LNG would expose the economy to global price volatility.
Striking the right balance between these two sources will be critical to ensuring long-term energy security and cost stability.
North Sea gas is proving to be a vital asset for the UK, delivering significant cost savings and strengthening energy security amid global uncertainty.
However, sustaining this advantage will require careful policy adjustments to encourage investment and maximize domestic production. In the long term, natural gas will remain an essential bridge in the transition toward a cleaner energy future.
