UK Treasury's North Sea Drilling Plan Vetoed by Energy Secretary as New PM Faces Supply Choice
Britain's energy secretary blocked Treasury plans to expand North Sea drilling for defense funds, intensifying the policy clash under the new prime minister.
Britain's new government is already fracturing over the North Sea. Energy Secretary Ed Miliband vetoed a Treasury proposal to boost UK oil and gas drilling, with the higher tax revenues earmarked to help fund Britain's increased defense spending, The Telegraph reported on Thursday (2026-06-25), citing unnamed officials.2
The veto matters because it lands just as the industry, trade unions and a new prime minister are trying to reset a policy framework that has pushed effective tax rates on North Sea production to 78%, among the highest in the world for a basin with steep operating costs.1
Brent crude front-month held at $93.81/bbl in early trading on Friday (2026-08-21), with Urals at $88.85/bbl and the OPEC basket at $91.27/bbl, levels that sharpen the fiscal stakes for a UK government weighing domestic output against import dependence. The Treasury's logic ran that higher drilling volumes would generate taxable income to help cover rearmament costs. Miliband's department rejected that framing outright.2
Under the previous prime minister, the industry had been pushing for exactly this kind of opening. Ahead of the leadership change, OEUK brought together industry leaders, trade unions and representatives of key economic sectors for a Westminster summit, arguing that fiscal and regulatory reform could lift domestic production to meet half of UK oil and gas demand, up from a third, while generating an additional £13 billion in tax receipts.5
Public sentiment sits with the industry. OEUK-commissioned research found 71% of the public believe homegrown production should be prioritised over imports.5
The new Energy Secretary, Miatta Fahnbulleh, met OEUK chief executive David Whitehouse on Thursday (2026-07-23), with the industry body calling the session "constructive." OEUK has also requested an "urgent prime ministerial visit" to operators in Scotland and to energy supply-chain companies in the Northeast of England.4,3
What the industry wants is concrete: early implementation of the government's proposed Oil and Gas Price Mechanism and the introduction of the Oil and Gas Revenue Levy, which OEUK argues would unlock £50 billion ($66 billion) of new investment.4,3
The numbers, though, come with caveats. The £13 billion tax receipt figure and the £50 billion investment unlock are OEUK's own analysis, not Treasury or independent forecasts. The IEA has criticised past North Sea approvals, and even the more modest Jackdaw tieback project has drawn environmental scrutiny from The Guardian's environment editor, Fiona Harvey, who argued it is "far less harmful than Rosebank" because it can connect to existing infrastructure and come online faster.6
History cuts both ways. North Sea revenues peaked at 3% of GDP in the mid-1980s and funded the Thatcher-era tax cuts that reshaped British politics. But the basin is mature, costs are high, and the tax burden has pushed capital elsewhere. Talk of a renaissance is fanciful, critics say, even as Labour's own policy remains a muddle.1
Analysts note the political turmoil that produced yet another prime ministerial resignation could force a rethink of how Britain uses its North Sea resources to reduce import dependence. But the Miliband veto suggests the energy security argument is not winning inside the cabinet.2
The market signals are mixed. UK carbon allowances traded at £58.22/tCO2 on Friday (2026-08-21), with ICE Endex TTF front-month at €65.30/MWh, up 2.98% in the previous session, and THE M+1 at €65.95/MWh, up 2.86%. A genuine production push would likely pressure UK carbon prices by shifting the generation mix, but the policy path to that outcome is blocked.2
What traders should watch is whether the new prime minister overrules Miliband on the Treasury plan, or whether the Energy Secretary's veto holds. The industry's requested PM visit to Scotland, if granted, would signal which way the government intends to move. If the veto stands, the £50 billion investment figure stays theoretical, and Britain's import dependence becomes the default outcome.3
