What are the 2015 Budget oil and gas tax cuts?

Reduction to Supplementary Charge

  • The headline change is a reduction in the supplementary charge from 30 percent to 20 percent. The supplementary charge is applied on a company’s ring-fenced oil and gas profits and is in addition to corporation tax (applied at 30 percent).
  • This reduction follows a recent 2 percent reduction down to 30 percent (from 32 percent) announced in the Autumn Statement 2014 and represents a dramatic turnaround, given that the charge was raised to 32 percent (from 20 percent) only in 2011.
  • The reduction in supplementary charge will be backdated, with effect from 1 January 2015.

Reduction to Petroleum Revenue Tax

  • The Petroleum Revenue Tax (PRT) rate will be reduced from 50 percent to 35 percent, with effect from 1 January 2016.
  • PRT is an individual field-based tax on profits from oil and gas production that applies to only mature fields that were given development consent before 16 March 1993. 

UK Continental Shelf Investment Allowance

  • A new investment allowance has been introduced, reducing the profits subject to the supplementary charge tax and simplifying the existing ad hoc allowance regime.   
  • The investment allowance is designed to encourage new spending and will remove an amount equal to 62.5 percent of investment expenditure from a company’s ring-fenced profits.
  • The allowance will apply to investment expenditure incurred on or after 1 April 2015.

What are the reactions to the changes?

The U.K. Treasury proclaims the proposed tax cuts as worth £1.3 billion to the industry and expects the changes to result in an additional £4 billion of additional investment, with extra production of 120 million barrels.

While the market seems to view these changes positively and agree that the tax cuts do increase the possibility of greater investment, notes of caution have been sounded by many commentators, who warn that these tax changes are not alone enough to revive the North Sea region. Many commentators argue that there needs to be a greater focus on exploration incentives and the current decommissioning regime, which poses a significant barrier to investment, given the mature nature of many fields in the region.

As of October 6, 2025, the Federal Energy Regulatory Commission (FERC) continues to operate despite the lapse in appropriations that resulted in a government shutdown on October 1, 2025. While FERC receives appropriations from Congress, it primarily is self-funded through fees and charges obtained from the industries it regulates, offsetting its total costs. Hence, during prior government shutdowns in 2018 and 2013, the agency was able to continue operations. However, FERC published a plan for operating in the event of a lapse in appropriations on September 30, 2025, available here

On August 29, 2025, Christopher Wright, the Secretary of the U.S. Department of Energy (DOE) submitted a proposal to the Federal Energy Regulatory Commission (FERC) under section 403 of the Department of Energy Organization Act (DOE Organization Act), asking that FERC terminate its long-running proceeding in Docket No. PL18-1, which addresses proposed updates to its policy statement on the Certification of New Interstate Natural Gas Facilities. The docket resulted in a draft policy statement that has never been finalized, nor relied upon by FERC in a published order, but would require FERC to consider environmental impacts and potential mitigation prior to making a public interest determination under the Natural Gas Act (NGA). The Secretary asks FERC to rescind the draft policy statement in its entirety to remove any uncertainty in gas infrastructure development. Rescission would require FERC to initiate a new docket and develop a new record should it want to reinitiate similar policy changes in the future.

On August 8, 2025, the Federal Energy Regulatory Commission (FERC) issued an enforcement order in Skye MS, LLC (Skye) and levied a $45,000 civil penalty on an intrastate pipeline operator in Mississippi, resolving an investigation into the operator’s violations of section 311 (Section 311) of the Natural Gas Policy Act (NGPA). FERC faulted the operator for providing a Section 311 transportation service without timely filing a Statement of Operating Conditions (SOC) and obtaining FERC’s approval for the transportation rates. Section 311 permits intrastate pipelines to transport interstate gas “on behalf of” interstate pipelines without becoming subject to FERC’s more extensive Natural Gas Act (NGA) jurisdiction, but requires the intrastate pipeline to have an SOC stating the rates and terms and conditions of service on file with FERC within 30 days of providing the interstate service. Under the NGPA, Section 311 rates must be “fair and equitable” and approved by FERC. In Skye, FERC stated that the operator began providing Section 311 service on certain pipeline segments in Mississippi in May 2023, following their acquisition from another Section 311 operator, but did not file an SOC with FERC until April 2025. The order ties the penalty to the approximately two-year delay between commencement of the Section 311 service and the SOC filing date. The pipeline operator was also ordered to provide an annual compliance report and to abide by additional verification requirements related to the filing of its FERC Form No. 549D, the Quarterly Transportation & Storage Report for Intrastate Natural Gas and Hinshaw Pipelines.

Circuit) upheld the Federal Energy Regulatory Commission’s (FERC) approval of a 1,000-foot natural gas pipeline segment crossing the United States-Mexico border (the Border Pipeline) under section 3 of the Natural Gas Act (NGA), rejecting environmental groups’ challenges that FERC improperly limited its analysis under both the NGA and the National Environmental Policy Act (NEPA), as related to a 155-mile intrastate “Connector Pipeline” constructed upstream of the Border Pipeline in Texas.

On July 15, 2025, the Federal Energy Regulatory Commission (FERC or Commission) issued an order1 proposing to eliminate the soft price cap of $1,000 per megawatt-hour (MWh) for bilateral spot sales in the Western Electricity Coordinating Council (WECC) that was implemented following the California energy crisis. If adopted, the Commission’s proposal would eliminate the requirement that sellers make a filing with FERC cost justifying spot market sales in excess of the soft price cap, which have become increasingly common in recent years as market conditions have continued to tighten throughout the West. Eliminating the WECC soft price cap would provide sellers that make sales during periods when prices exceed the cap greater certainty that their sales will not be second guessed after the fact.
