NSTA signals North Sea drilling ahead as BP weighs exit from UK basin
BP's reported push to sell UK assets and a regulator's call for fiscal reform put pressure on London's clean energy investment pitch.
North Sea Transition Authority chief Doris Reiter said on Tuesday (2026-06-09) that the regulator is "not saying no" to new North Sea development, pointing to the Clair field moving into its third phase, even as BP reportedly weighs selling its UK oil and gas assets and demands a "more stable" fiscal regime.2
BP's potential exit would be the most significant supermajor retreat from the basin since the windfall tax was introduced. The company has yet to submit applications to the government for extensions on existing licences, according to Energy Voice reporting on Tuesday (2026-06-09), leaving the Clair third phase in an uncertain state despite Reiter's encouraging language.2
Reiter's public criticism of the UK fiscal climate was a rare move for a regulator whose core function is maintaining industry interest in the basin. Her remarks land at an awkward moment for the Treasury, which is trying to keep North Sea investment alive without formally acknowledging that the tax regime is driving away its largest operator.2
The fiscal argument plays out against a global spending backdrop that is moving decisively away from fossil fuels. The IEA's World Energy Investment 2026, published in May, projects that of the $3.4 trillion the world will spend on energy this year, $2.2 trillion goes to clean energy and $1.2 trillion to fossil fuels, according to OilPrice.com reporting in June. The agency also estimates that clean energy and efficiency saved the world's five largest fuel-importing regions $260 billion in avoided fossil fuel import costs in 2025.3
That spending gap matters for the UK's ability to attract transition capital. London is pitching itself to offshore wind developers, nuclear investors and grid financiers, all of whom need multi-decade revenue certainty. A government that can reprice existing oil field cash flows through windfall taxes while simultaneously encouraging new drilling sends a mixed signal to investors evaluating both types of assets.2
Not everyone in the asset management industry thinks that ambiguity is necessarily a problem. Amundi, Europe's largest asset manager, is actively lobbying the European Union to allow funds to hold oil and gas companies within transition-focused fund categories. Elodie Laugel, Amundi's chief responsible investment officer, told Rigzone that proposed revisions to SFDR, which covers assets worth about $14 trillion, do not go far enough in permitting managers to include oil and gas in transition funds, arguing the sector is crucial to the shift.4
The broader market data on fossil exclusions is mixed. Fossil energy accounted for 30% of all sector exclusions in the second quarter, up 4 percentage points in three months, according to Covalence analysis cited by Rigzone. But top renewable-power users outperformed fossil-heavy peers by 6% through May, suggesting the transition trade is gaining traction in performance terms even as some large managers push back on blanket exclusion rules.4
Reiter's comments were carefully limited in scope. She cited existing licences and named Clair specifically, but stopped well short of signalling a new licensing round. That is the narrowest possible reading of "not saying no" — enough to reassure the industry without committing the regulator to anything that would sharpen the political conflict over North Sea expansion.2
The global context does not make the UK's position easier. China's CO2 emissions climbed 2% in early 2026 partly because of wasted wind and solar output, and there was 206GW of coal-fired capacity still under construction in January after record additions in 2025, according to Carbon Brief analysis from June. Those numbers reflect how hard it is for any single government to thread the needle between energy security and transition credibility, even with the best-designed policy.1
BP's formal decision on its UK assets is the clearest near-term signal for the basin. If the supermajor exits, the North Sea loses its most capable remaining operator and a significant share of the technical expertise needed to manage late-life infrastructure safely. If it stays, the price is likely to be fiscal concessions from a Treasury that has few of them to offer. Reiter has made the problem visible; neither she nor the government has indicated how it gets resolved.2
