Why the UK must prioritise energy sovereingty above security

UK energy policy has long emphasised security and resilience. Diversified imports, interconnectors and crisis plans are important – they enable flexibility, efficiency, trade and cost optimisation, and help to manage geopolitical risks. But these benefits only matter if the UK first secures sovereignty. Security and resilience are tools, not substitutes for control. Energy sovereignty does not mean isolating from international energy markets or ending imports, nor does it oppose collaboration. It means having the domestic capacity and control to protect against the worst-case scenarios, ensuring that dependence cannot dictate the UK’s energy, industrial or economic fate. Without sovereignty, security is conditional, resilience is fragile and the country remains exposed.

Sovereignty is not isolation – it is control

Energy sovereignty does not mean self-sufficiency at all costs, withdrawal from global markets or abandoning the UK’s legally binding 2050 net zero commitments. It means retaining meaningful control over national infrastructure, supply chains and domestic resources. Great British Energy embodies this approach – focusing on domestic investment, coordinated infrastructure and the ability for the UK to make its own energy choices.

Security and resilience are still necessary. They support flexibility, trade, efficiency and cost optimisation, and help to manage geopolitical risk. But they can only deliver those benefits once sovereignty is guaranteed. Without it, security is conditional, resilience is fragile and policy becomes reactive, rather than strategic.

The supply chain case for retaining domestic hydrocarbons

Supply chains and skilled jobs are deeply integrated. Engineers, supply chains, ports and fab-yards, offshore workers – all are transferable between oil, gas and other energy technologies. Prematurely exiting domestic hydrocarbons risks eroding these capabilities just as they will be needed in the long-term to maintain fuel sovereignty, support industrial expertise and underpin the transition to low-carbon energy. Without these domestic foundations, future energy infrastructure – offshore wind, hydrogen and nuclear – will increasingly have to be supplied by global supply chains, increasing strategic vulnerability and leaving the UK dependent on external expertise for technologies that are critical to its energy independence.

Maintaining a domestic oil and gas sector while developing renewables is therefore not a contradiction – it is a necessary pillar of sovereign energy policy.

Other nations, such as Norway and the UAE, understand this. They are protecting and reindustrialising their oil and gas sectors for the supply chain, technical expertise and workforce foundations that they provide. The UK should follow suit: protect what it has, invest in it and leverage domestic supply chains to underpin sovereign energy policies. Delivering net zero is compelling, but it can be delivered in a more effective and coordinated way.

Sovereignty can also reduce energy costs

The current policy mix also inflates costs unnecessarily. Today’s high energy prices reflect three factors: exposure to volatile global markets, financing uncertainty and the high total levelised costs of decarbonisation and renewables, including grid build-out, last-mile connections, curtailment and storage. Sovereignty can mitigate these with domestic generation stabilising prices and predictable policies that reduce financing risk. Local supply chains, under the umbrella of energy sovereignty, also make it easier to reduce energy costs by improving control over project delivery, stabilising investment and capturing efficiencies within the domestic economy.

Sovereignty is not optional; it is the foundation of security, resilience and real energy independence

A unifying goal in a divided debate

Sovereignty would be a clear, unifying goal, countering current green policies that are dividing the nation – policies that enjoy strong support among younger voters but increasingly worry older voters and SME business leaders, who bear most of the burden of job insecurity and higher energy costs.

Energy and defence: two sides of the same coin

National security policy underscores the point. The British Government has committed to raising existing lacklustre defence spending from 2.3% of GDP today to 5% by 2038. If the UK is willing to make this investment to protect its borders and alliances, it must also align other critical sectors, such as energy, food, manufacturing, pharmaceuticals and data centres. Defence without industrial and energy sovereignty would leave the country further exposed. 

Sovereignty as the foundation, not the alternative

The UK does not need to abandon energy security, resilience or international collaboration. But these must become outcomes of sovereignty, not substitutes for it. Prioritising energy sovereignty protects domestic supply chains, strengthens resilience, reduces costs and underpins long-term economic and strategic autonomy – all while still allowing imports and cooperative engagement with global energy markets.

In energy, as in geopolitics, sovereignty is about choice, protection and independence, not isolation. Without it, the UK remains vulnerable and dependent. With it, the country can make its own decisions on energy, industry, decarbonisation and the economy while still engaging internationally. Sovereignty is not optional; it is the foundation of security, resilience and real energy independence.

Definitions

Energy sovereignty

The capacity of a territory to meet its energy needs in an autonomous way to guarantee its independence, having direct control over its energy resources, production and infrastructure.

Energy security

The uninterrupted availability of energy sources, whether from domestic or international sources, to ensure a reliable, consistent and economical supply of energy to keep homes and businesses running smoothly.

Energy resilience

The ability of an energy system to prepare for, withstand, adapt to and quickly recover from disruptions such as blackouts, cyberattacks or extreme weather, ensuring a reliable fuel and power supply.
