High Oil Prices and Tax Incentives to Accelerate New Energy Deals in the UK North Sea

Mergers and acquisitions in the UK North Sea oil and gas sector are expected to increase. High energy prices, tax burdens and operating costs are pushing companies towards consolidation.

According to industry analysts and investment bankers, transactions involving oil and gas assets in the UK North Sea could gather further momentum this year. While high energy prices are boosting companies' financial capacity, rising costs and tax burdens are encouraging smaller operators to merge with larger players.

Oil and gas prices have climbed to multi-year highs amid supply disruptions linked to the US-Israel war, generating substantial revenues for energy companies. At the same time, rising prices have intensified inflationary pressures and brought the economic viability of domestic energy production in the UK back into focus.

According to London Stock Exchange Group (LSEG) data, the total value of oil and gas mergers and acquisitions involving UK companies as either targets or buyers has reached $19.6 billion since the beginning of the year. This has already exceeded the $16.5 billion recorded in 2025.

As a result, 2026 could become the most active year for dealmaking in the British oil and gas sector since at least 2022.

Smaller Operators Under Pressure to Merge

James McCormack of investment bank Cavendish said that although the pool of potential buyers remains relatively limited, this has not prevented further deals from taking place.

In his view, the UK North Sea market is becoming increasingly concentrated among companies with the financial strength, tax capacity and ability to cover the costs of decommissioning major assets.

A previous Cavendish report also noted that high production costs at ageing oil and gas fields are creating additional pressure for consolidation.

Alexander Franke, an energy adviser at Oliver Wyman, also expects cost optimisation to encourage further acquisitions. According to him, the pace of dealmaking will depend on the future direction of oil prices.

A sharp decline in energy prices could prompt potential buyers to adopt a wait-and-see approach. Conversely, prices remaining high could strengthen companies' cash flows and their ability to finance acquisitions.

78% Tax Rate Accelerates Consolidation

One of the key factors encouraging mergers in the North Sea is the UK's tax policy.

The Energy Profits Levy, introduced by the previous Conservative government and increased under the current Labour administration, has raised the overall tax rate on oil and gas production to 78%.

Greg Aitken, director of corporate research at Wood Mackenzie, said that tax-driven consolidation has been widespread in the British energy sector in recent years.

Tony White of consultancy firm MKI believes that a merger between two UK North Sea operators could allow the enlarged company to benefit from tax advantages and operational synergies.

Uncertainty Over Government Energy Policy

Another important factor influencing investors' decisions is uncertainty surrounding the British government's energy policy.

The government remains committed to achieving net-zero greenhouse gas emissions by 2050. However, the approval granted this month for the development of the Jackdaw gas field has reignited debate over the country's energy strategy.

Although the government has stated that oil and gas will remain important components of the country's energy mix for years to come, the economic and environmental implications of investing in new projects remain controversial.

Environmental campaigners argue that investment in new fossil fuel projects is incompatible with climate targets. Supporters of the projects, meanwhile, emphasise that domestic production can reduce dependence on imports while supporting jobs and energy security.

BP's North Sea Asset Sale in Focus

In recent years, major international oil companies have begun scaling back their activities in the North Sea and redirecting investments towards other regions.

Shell has opted to maintain its remaining presence in the region through partnerships, including the creation of the Adura joint venture with Norway's Equinor.

In July this year, BP announced plans to review its portfolio and sell its North Sea oil and gas assets as part of efforts to improve profitability.

Analysts estimate that the sale of BP's assets could generate approximately $2 billion and trigger another wave of consolidation in the sector.

According to James McCormack of Cavendish, the main potential buyers could be companies already operating in the North Sea and seeking to expand their market positions.

EnQuest, NEO NEXT+ and Ithaca have been named among the possible buyers.

A source familiar with the process told Reuters that the next stage of the tender for BP's assets is expected to take place in December.

EnQuest Chief Executive Officer Amjad Bseisu has confirmed the company's interest in the assets.

Major Deals Increase Across the North Sea

The consolidation trend in the British energy market is already reflected in several major transactions.

In September, London-listed Genel Energy increased its offer for Capricorn Energy to $436 million, surpassing the bid from Norway's DNO.

In August, Israel's Ratio Petroleum made a $196 million offer for Pharos Energy, outbidding Serica Energy.

Earlier this month, Gulf Keystone Petroleum and ShaMaran Petroleum announced an all-share merger agreement valued at $601 million.

In addition, Ithaca Energy agreed to acquire three offshore oil assets from Canada's Suncor for C$1.2 billion (approximately $853.5 million).

Pharos Energy Chief Executive Officer Catherine Roe said the competitive takeover interest in the company had come as a surprise.

According to her, high operating costs and limited diversification make smaller producers more vulnerable to political, operational and energy price risks.

Roe believes that consolidation could improve operational efficiency and increase returns for investors.

H igh energy prices, tax burdens and production costs are accelerating changes in ownership structures across the UK North Sea. BP's planned asset sale, together with major transactions already announced, could mark the beginning of a broader consolidation phase in the region.
