In its Autumn Budget, the UK government has confirmed the Energy Profits Levy (EPL), a windfall tax on oil and gas companies, will remain in place until 2030. This decision, leaked ahead of the official announcement, represents a significant setback for the industry, which had been lobbying for the tax's early removal to protect investment and jobs in the North Sea.

Industry Reaction and Economic Forecasts

The industry body Offshore Energies UK condemned the decision, labeling it a "bitter blow" that would lead to continued job losses, increased energy imports, and a loss of £50 billion in potential investment. The Office for Budget Responsibility forecasts that EPL receipts will decline from £2.7 billion in 2025-26 to £0.3 billion by 2030-31, a figure lower than previous estimates due to falling crude prices and the impact of mergers and acquisitions. The government faced a difficult decision, as removing the tax entirely was complicated by a hole in public finances and an election mandate for climate action.

Post-2030 Tax Mechanism and Licensing Ban Concessions

While maintaining the EPL, the government provided clarity on the tax regime that will replace it after March 2030. A new revenue-based model will be introduced, taxing excess revenues above specific price thresholds. The tax rate will be 35%, with thresholds set at $90 per barrel for oil and 90p per therm for gas, to be reviewed annually. This mechanism is designed to directly link tax liability to exceptional market conditions. Furthermore, the government softened its pledge on a licensing ban. Under the new "North Sea Future Plan," operators will be granted "Transitional Energy Certificates" to allow "limited" near-field production via tie-backs to existing infrastructure. However, no new exploration is permitted at these sites, and no new onshore licenses will be granted.

Implications and Mitigation Efforts

The dual announcements have mixed implications. The softened licensing stance, a policy shift influenced by research from the University of Aberdeen, was welcomed as a sign the government is willing to listen to evidence supporting North Sea energy security. However, the maintained EPL is expected to continue dampening investment appetite, as reflected in falling share prices for major UK independents like Harbour Energy. To address forecast job losses in oil and gas, the government plans to create a North Sea Jobs Service, offering tailored support for workers transitioning into clean energy, defence, and manufacturing sectors.
