Taxes and high oil prices set to extend the UK North Sea's deal spree

Mergers and acquisitions involving a UK oil and gas target or buyer have reached $19.6 billion year-to-date, according to LSEG data, already clearing the $16.5 billion recorded for the whole of 2025 and making 2026 the strongest year for activity since at least 2022 — the last energy crisis, triggered by Russia's full-scale invasion of Ukraine.

Eleven industry analysts and bankers, in a Reuters analysis carried by Free Malaysia Today, said tax advantages and high energy prices will drive further consolidation across Britain's ageing North Sea fields. The two summaries of the same analysis published by Business Day and TimesLIVE frame the industry as facing mounting pressure to consolidate amid rising costs, policy uncertainty and a drive for efficiency.

The cash is there. Oil and gas prices have climbed to multiyear highs on disruption linked to the US-Israeli war with Iran, generating large sums for an industry that has been reporting results this week. Those same price gains have pushed up inflation more broadly, sharpening the appetite for scale to justify production in a mature basin that the British government treats as a secure domestic supply source.

A 78% headline rate

The fiscal regime is doing much of the work. An Energy Profits Levy introduced by the previous Conservative government and increased under the current Labour government has lifted the headline tax rate on UK upstream oil and gas activity to 78%.

"There's been a lot of tax-driven consolidation in recent years," said Greig Aitken, director of corporate research at Wood Mackenzie.

Tony White of advisory firm MKI pointed to the same logic: "There's still a rationale for two UK North Sea players to combine, so that the enlarged company can take advantage of the tax credits as well as operational synergies."

The buyer pool is thin, however. James McCormack of Cavendish described the basin as "an increasingly concentrated market when it comes to credible buyers with the balance sheet, tax capacity and decommissioning capability to execute material deals" — a small group, he said, but not small enough to preclude more transactions. A September Cavendish report argued that "companies that can offer diversification, liquidity and development capital are attracting premium valuations, while sub-scale operators face growing pressure to merge, seek capital in deeper markets, or accept takeover approaches."

Alexander Franke, an energy consultant at Oliver Wyman, expects cost containment to drive activity, with the pace contingent on the oil price outlook. A surprise slide in prices could deter buyers; a sustained rally would bolster the cash flow and funding available for acquisitions.

Policy cuts both ways

Government policy remains the other variable. Britain says it is still committed to net-zero greenhouse gas emissions by 2050, yet it approved development of the Jackdaw North Sea gas field earlier this month after years of debate — environmental campaigners argued there was no justification for new fossil fuel investment, while supporters cited jobs and a domestic gas source with a lower environmental cost than imports. In Wednesday's autumn budget statement the government restated its long-term commitment to keeping oil and gas in the energy mix, but announced no new measures for the sector.

The majors have been exiting for years. Shell now manages its remaining North Sea exposure through partnerships and joint ventures, including Adura, created with Norway's Equinor. BP, the last major with a significant North Sea focus, said in July it would sell its oil and gas fields in the basin as part of a portfolio overhaul; analysts have estimated the sale could raise $2 billion and set off another consolidation wave. McCormack said the likely buyer is another North Sea consolidator, with value driven by infrastructure and tax synergies rather than reserves alone, and named UK companies EnQuest, NEO NEXT+ and Ithaca as possible bidders. A person with knowledge of the process said the next round of bidding will come in December. EnQuest CEO Amjad Bseisu has said he is interested in the assets; Ithaca declined to comment and NEO NEXT+ did not respond to a request for comment.

A wider cycle

The activity is not confined to one seller. London-listed Genel Energy in September raised its offer for Britain's Capricorn Energy to $436 million, outbidding Norway's DNO. Israel's Ratio Petroleum outbid Serica Energy in August with a sweetened $196 million offer for Pharos Energy; Serica said it continues to evaluate acquisition opportunities in the UK North Sea and internationally. This month Gulf Keystone Petroleum and ShaMaran Petroleum announced a $601 million all-share merger, while Ithaca agreed to buy three offshore oil assets from Canada's Suncor for C$1.2 billion ($853.49 million).

For dealmakers, the setup is straightforward: a high tax rate that rewards scale and tax credits, a mature basin where costs are relatively high, and a government that wants domestic supply kept in the mix. The swing factor remains the commodity — and with prices at multiyear highs, both buyers and sellers have reason to move.
