FRC launches three investigations into Prax Group's collapse

The Financial Reporting Council (FRC) confirmed on 21 July 2026 that it has opened three separate investigations into the collapse of Prax Group, the UK energy challenger that entered administration earlier this year. The regulator’s conduct committee approved the probes, which focus on the financial oversight of Prax’s parent company, State Oil, and on the audit work performed by KPMG for the fiscal years ended 28 February 2022 and 28 February 2023, as well as by PKF Littlejohn for the fiscal year ended 29 February 2024.

Scope of the three probes

According to the City AM report, the first investigation will examine how State Oil Company of Azerbaijan Republic – the parent of Prax – managed financial oversight of its subsidiary. The second probe targets the Big Four auditor KPMG, scrutinising its audit of Prax for the two most recent fiscal years (FY 2022 and FY 2023). The third investigation looks at the mid‑tier firm PKF Littlejohn, which took over the audit role in the period leading up to Prax’s collapse, and will assess its audit of the FY 2024 accounts.

Timeline of regulatory action

The FRC’s conduct committee met on 21 July 2026 and voted to launch the three investigations. The regulator made the decision public on 14 September 2026 via a press statement that was reproduced in City AM. The timing is notable because the UK government sold the Lindsey Oil Refinery to Phillips 66 in April 2026, a transaction that has already drawn scrutiny for its impact on the wider energy sector.

Background on the entities involved

State Oil Company of Azerbaijan Republic, headquartered in Baku, employs roughly 70 000 people and operates in the petroleum industry. The Wikidata entry used for background notes that the chief executive is not confirmed, and the employee count may be outdated – the regulator’s statement does not provide further detail.

KPMG, a UK‑based professional services firm, is led by chief executive Marie Guillemot and employs about 219 281 staff worldwide. The firm resigned as Prax’s independent auditor in the months before the collapse, prompting the appointment of PKF Littlejohn.

PKF Littlejohn is a mid‑tier audit firm that assumed the audit mandate for Prax in the run‑up to its insolvency. The regulator’s probe will assess whether the audit for FY 2024 met the required standards, but no further information on the firm’s size or leadership is supplied in the packet.

Implications for stakeholders

The three investigations could have material consequences for a range of stakeholders. Investors in Prax and its creditors will be watching for any findings that attribute responsibility to the parent’s oversight or to audit deficiencies. Should the FRC identify breaches of auditing standards, KPMG and PKF Littlejohn could face sanctions, fines or restrictions on future audit work in the UK.

Regulators and policymakers will also be interested in whether the oversight failures at State Oil point to broader governance issues in state‑owned enterprises that have cross‑border operations. The timing of the probes, coming weeks after a high‑profile refinery sale, may prompt further scrutiny of the UK’s energy‑sector oversight framework.

What remains unknown

• The exact nature of any alleged oversight lapses at State Oil has not been disclosed.
• The FRC has not indicated the expected duration of each investigation.
• Details on the specific audit findings that triggered the probes are absent from the public statement.
• Confirmation of State Oil’s current chief executive and any recent changes to its employee headcount are pending verification.

Further updates are expected as the conduct committee’s investigations progress. The regulator’s next public briefing is likely to provide more detail on the scope and any interim findings.
