Tories take Aberdeen South as Streeting signals North Sea drilling U-turn

Tories take Aberdeen South as Streeting signals North Sea drilling U-turn A Conservative by-election win and Labour's softening on new licences reframe North Sea politics, yet a depleted basin and 78% tax rate cap any supply revival. Douglas Lumsden, a Conservative, won the Aberdeen South seat at the Scottish Parliament by-election on Friday (2026-06-19), a contest both campaigns had billed as a referendum on the North Sea. Kemi Badenoch, the Conservative leader, called the result a triumph for oil and gas workers, and Lumsden used most of his acceptance speech to attack the SNP and the Labour government over the basin's future.^6,7 The result landed three days after Wes Streeting said he would overturn the ban on new licences for North Sea oil and gas drilling, a reversal that handed the Conservatives' central argument to a Labour front-bencher. Whether louder drilling politics translates into actual molecules is the test for gas traders. The early read is that it does not.⁵ Uplift, a green campaign group, dismissed the premise outright. The UK has already burned "most of its gas", the NGO said on Tuesday (2026-06-16), arguing that fresh licences cannot reverse the depletion of a mature basin. Uplift's claim rests on geology. The recoverable resource has largely been produced, the group argues, so a marginal new well does little for national supply.⁵ That argument has support well beyond the campaign groups. The Economist, surveying what it called the collapse of Britain's oil-and-gas industry, judged Labour's policy a muddle but critics' talk of a North Sea renaissance fanciful. North Sea revenues peaked at about 3% of GDP in the mid-1980s and have dwindled since. Britain's effective tax rate on the basin now runs at 78%, among the highest in the world, deterring investment in fields that already carry high production costs.⁴ Where new North Sea supply is genuinely coming, it is Norwegian, not British. Norway's energy ministry approved plans on Tuesday (2026-05-19) to reopen the Albuskjell, Vest Ekofisk and Tommeliten Gamma gas fields in the southern North Sea in 2028, three decades after they were shut, Montel reported. The three together were expected to yield about 90-120m barrels of oil equivalent, mostly gas and condensate, on roughly EUR 1.8bn of investment.¹ Operator ConocoPhillips told Montel that production should start in the fourth quarter of 2028 at 5.7m cubic metres a day, around 1.5% of average daily output. Even a real reopening of mothballed fields adds only a sliver of supply, and not before late 2028.¹ Prices give the political fight little to work with. UK NBP gas eased to about €50.51 on Friday morning (2026-06-19), off roughly 1.6%, while Dutch TTF held near €41.94. New UK licences, even if granted, would not deliver gas for years, so the near-term direction in NBP and UK baseload turns on weather, storage and Norwegian flows rather than the outcome of a Scottish by-election.¹ The political heat is real even where the geology is not on the politicians' side. Britain faces its second energy crisis in four years, first from Russia's invasion of Ukraine and now from disruption to Gulf oil supply, the Guardian noted, with both main parties accused of failing to prepare. Fatih Birol, the IEA's executive director, said the oil shock from the Iran war had pushed importing countries to treat fossil-fuel dependence as a security risk.^3,2 The signal worth tracking is the licensing itself rather than the campaign rhetoric. If Streeting's position becomes government policy and new rounds open, the supply effect still sits years out and runs through a high-cost, heavily taxed basin. First gas from the three reopened Ekofisk-area fields, due in late 2028, is a more concrete addition to North Sea balances than anything settled at the ballot box in Aberdeen South.^1,4
