BP's North Sea Exit Forces Burnham's Hand on Rosebank and Jackdaw
BP's decision to sell its UK upstream business has sharpened the political calculus around two contested North Sea projects that could unlock GBP 50 billion in investment.
BP announced on 2026-07-31 that it was putting its UK oil and gas business up for sale, a move the Aberdeen and Grampian Chamber of Commerce called a "defining moment" for Prime Minister Andy Burnham. Russell Borthwick, chief executive of AGCC, said the country needed to "reset the relationship with our offshore" sector. Burnham replied by asking publicly how many more North Sea jobs needed to be lost.7
The sale removes one of the basin's largest operators at a moment when investor appetite for North Sea spending is already under pressure. A buyer for BP's UK upstream book needs confidence that the regulatory and fiscal environment will support new drilling rather than a managed run-down of reserves. Without that, the sale risks attracting buyers focused on extraction over development — narrowing the pipeline of new supply that Burnham is simultaneously trying to protect.7
Two projects sit at the centre of his options. Jackdaw is a gas tieback that can connect to existing infrastructure; the Guardian's environment editor Fiona Harvey has noted it could come online quicker than a greenfield development. Rosebank is the North Sea's largest undeveloped oil and gas field, with a larger resource prize, but it has drawn wide criticism from the International Energy Agency. Burnham must decide on both.8
Labour MPs and climate campaigners largely dropped their resistance to Jackdaw by late June (2026-06-29), according to E&E News, as Burnham prepared to take office. They said they would keep fighting Rosebank. One project has cleared a political path; the other carries a much higher political cost alongside its larger prize.5
Burnham moved quickly after taking office in mid-July. Within days of arriving, his team asked civil servants to draw up plans for new energy and water policies that could be announced as early as the week of 2026-07-20, according to people familiar with the matter.6
The government he replaced left a difficult inheritance. Then-Energy Secretary Ed Miliband vetoed a Treasury proposal on 2026-06-25 that would have expanded North Sea drilling to fund defence spending through higher tax revenues, The Telegraph reported. That decision, taken under a government that had already restricted new licensing on climate grounds, narrowed the fiscal options now available to Burnham.4
The strategic pressure behind new North Sea development has grown through two successive supply shocks. Russia's full-scale invasion of Ukraine was the first; the Iran war and subsequent Gulf oil shipping blockade was the second. IEA executive director Fatih Birol said in May (2026-05-20) that the Gulf crisis had changed the global fossil fuel industry by accelerating countries' shift away from petroleum imports. Britain's exposure to both disruptions has reinforced the energy security argument for domestic production, though it has not resolved the political divisions over which projects to approve.1,2
Offshore Energies UK held emergency talks with sector leaders in late May (2026-05-25), arguing that early implementation of the Treasury's Oil and Gas Price Mechanism alongside accelerated approval of Rosebank and Jackdaw could unlock GBP 50 billion ($61.1 billion) in investment. OEUK did not specify what share of that total depended on Rosebank versus other projects, or on BP's continued presence as an operator.3
Analysts have said the latest prime ministerial transition offered an opportunity to recalibrate how North Sea resources reduce UK import dependence, though that argument has been made at each such transition for a decade.4
ICE Brent crude front-month was at $88.82 a barrel as of 2026-08-16, and NBP Q+1 gas sat at €63.46 per MWh on the same date. Jackdaw, as a tieback feeding directly into existing pipelines, would reduce UK exposure to European hub pricing more quickly than Rosebank's slower development timeline could. Rosebank would deliver more volume, eventually.8
How much of the OEUK investment figure materialises now depends partly on who buys BP's upstream book and on what terms they are willing to develop new wells rather than simply harvest mature fields. The sale process, and Burnham's licensing decisions, are running in parallel, and neither is yet resolved. The first concrete signal will come from whichever project he approves first — and the fiscal framework he attaches to it.7,3
