BP has launched a formal sale process for its UK North Sea business, the company announced on 31 July, marking a potential end to more than sixty years of continuous offshore production by one of the industry’s founding operators in the basin.
The business encompasses five production hubs — Andrew and Etap in the central North Sea, and Glen Lyon, Clair and Clair Ridge west of Shetland — and produced 117,000 barrels of oil equivalent per day in 2025, representing approximately 5% of BP’s total global oil and gas output. Around 1,100 staff are employed within the North Sea arm of the group, which forms part of BP’s broader UK workforce of roughly 13,960.
Chief executive Meg O’Neill framed the decision in terms of capital discipline and portfolio focus. “The North Sea remains integral to the UK’s energy system,” she said. “However, as we focus our portfolio and direct capital to our highest-value opportunities, we believe our North Sea business will be better positioned as part of another company. It has world-class people, resilient assets and a proud heritage.” The sale process forms part of a wider strategic effort to slim the group, redirect investment towards core upstream, downstream and trading operations, and strengthen the balance sheet — an effort that has already seen BP agree to sell a 65% controlling stake in its Castrol lubricants business to infrastructure firm Stonepeak, a transaction expected to close by the end of 2026 subject to regulatory approval.
The symbolism of the move should not be understated. BP helped shape the UK offshore industry from its earliest days and describes the Clair field, west of Shetland, as the largest on the UK continental shelf, with an estimated seven billion barrels of oil in place. Clair Ridge, the second phase of that development, began production in 2018 with a design recovery target of 640 million barrels. That BP now judges these assets better held by another operator reflects both the company’s internal reorientation and the deteriorating fiscal environment that has weighed on the basin for the better part of a decade.
The Energy Profits Levy, introduced in 2022 and raised to 38% from November 2024, has pushed the headline tax rate on UK upstream oil and gas activities to 78%, with the charge extended through to March 2030. The government’s concurrent removal of the levy’s main investment allowance compounded the burden, and the cumulative effect of repeated fiscal changes has eroded operator confidence in the basin’s long-term competitiveness. Russell Borthwick, chief executive of Aberdeen and Grampian Chamber of Commerce, was direct in his assessment: “Today’s announcement from BP should be a defining moment for the new Prime Minister. How many more jobs need to be lost before the UK Government acts? This decision is another stark reminder that confidence in the UK Continental Shelf has been badly shaken after years of policy uncertainty, punitive taxation and mixed messages about the future of the industry.”
The political backdrop adds a further layer of complexity. Prime Minister Andy Burnham has recently signalled a more pragmatic stance on North Sea drilling, telling reporters he had informed Donald Trump that “we can’t ignore” the resources there and that he would “take a pragmatic approach when it comes to the North Sea.” That position sits in some tension with Labour’s 2024 manifesto commitment not to issue new licences, and with the firmly restrictionist posture previously adopted by former Energy Secretary Ed Miliband. Trade unions, industry figures and a number of Labour MPs have pressed for a clearer commitment to increased drilling activity, and BP’s announcement is likely to intensify that pressure.
BP’s retreat is not an isolated episode. ExxonMobil, Chevron and ConocoPhillips have all divested North Sea assets in recent years, while Shell and Equinor have consolidated their UK offshore positions into a joint venture. The direction of travel among major international operators is consistent, shaped by a combination of declining production from a maturing basin and a tax regime that compares unfavourably with competing jurisdictions. BP also announced separately that it intends to cut approximately 700 jobs globally from its production and operations business, reducing non-frontline roles by around 8%. The company stated it would continue to operate the North Sea business safely and reliably throughout the sale process.
