The UK North Sea oil and gas industry faced unprecedented challenges in 2025, marking one of the most difficult years since the basin was first discovered in the 1960s. Oil and gas production from mature fields continued to decline, while uncertainties loomed over the industry due to changes in the UK government’s fiscal policies.
The lack of incentives and investment allowances, coupled with a punitive windfall tax, led to a significant reduction in investments and frozen plans by companies operating in the UK offshore oil and gas sector. Exploration activity in the UK North Sea hit an all-time low, with not a single exploration well drilled in 2025, a concerning trend highlighted by consultancy Wood Mackenzie.
One of the major challenges facing the industry was the windfall tax, officially known as the Energy Profits Levy (EPL), which remained unchanged until 2030. The tax, triggered by oil prices above $76 per barrel or natural gas prices at 59 pence per therm, added to the already high tax burden on operators, making the UK a less attractive investment destination compared to other jurisdictions with more favorable fiscal regimes.
Industry leaders expressed their dismay at the government’s decision to retain the windfall tax, with Offshore Energies UK chief executive David Whitehouse criticizing the move for turning down significant investment opportunities and putting jobs at risk. The Aberdeen & Grampian Chamber of Commerce also warned of dire consequences, stating that the decision signaled the end of North Sea production and would lead to job losses and a decline in the industry.
The impact of the windfall tax was evident in the workforce reductions announced by companies like Harbour Energy, which planned to cut 100 jobs on top of the 600 already eliminated since 2023. Harbour Energy’s chief executive, Linda Cook, lamented the unfavorable fiscal environment in the UK compared to other countries where the company operates, highlighting the challenges faced by operators in the region.
In response to the challenging fiscal environment, operators in the UK North Sea are exploring alternative strategies to survive, including mergers and acquisitions to create value for shareholders and boost profitability. As the industry navigates through turbulent times, the survival of the fittest mergers and collaborations may be crucial for sustaining operations in the UK North Sea. Mergers have become a common solution for companies in the oil and gas industry as they seek to cope with the high tax rates imposed by the UK government. Last month, Harbour Energy made headlines with its acquisition in the UK North Sea, a strategic move to navigate the challenges posed by the UK windfall tax.
Scott Barr, Managing Director of Harbour’s UK Business Unit, emphasized the significance of the acquisition, stating that it was a crucial step for Harbour in the UK North Sea amidst the fiscal and regulatory obstacles. The deal involved the purchase of Waldorf Energy Partners Ltd and Waldorf Production Ltd, both currently in administration, for a sum of $170 million.
Harbour Energy is just one of many operators in the UK that have pursued acquisitions to strengthen their positions in the region. Shell and Equinor recently announced the launch of a joint venture, Adura, consolidating their offshore UK oil and gas operations. Additionally, TotalEnergies merged its upstream UK business with NEO NEXT to create NEO NEXT+, the largest independent oil and gas producer in Britain.
Industry analysts predict that the trend of consolidation will continue as companies seek to navigate the challenging fiscal environment. Many in the industry are calling on the government to reform the fiscal regime to encourage investment and support job creation. Ineos, a prominent energy and chemicals group, expressed concerns about the impact of current policies on future investments in the UK.
As the industry grapples with these challenges, stakeholders are emphasizing the importance of balancing climate commitments with economic stability. Restoring investment in the North Sea is seen as crucial for safeguarding jobs, stabilizing the economy, and transitioning to a cleaner energy future. Companies are urging policymakers to create a supportive environment that enables businesses to invest in sustainable energy solutions.
In conclusion, the oil and gas industry in the UK is facing significant challenges, prompting companies to seek solutions through mergers and acquisitions. As the sector consolidates, there is a growing consensus on the need for policy reforms to support investment and ensure a sustainable energy future. By addressing these challenges proactively, the industry can navigate the current fiscal landscape and contribute to a more resilient and environmentally conscious energy sector.
