Nick Ephgrave’s retirement leaves Serious Fraud Office at a crossroads
Tony McClements takes a look back at Nick Ephgrave’s reforms at the SFO and contemplates what’s next for the organisation.
The Serious Fraud Office (SFO) occupies a unique position in the UK’s enforcement landscape.
Tasked with investigating and prosecuting the most serious and complex fraud, bribery, and corruption cases in England, Wales, and Northern Ireland, often involving multinational corporates, politically exposed persons, and jurisdictions with limited transparency, its reputation has been decidedly mixed during the past decade.
Now the resignation of its high-profile boss, Nick Ephgrave, has cast further doubt on the organization’s future and direction.
Backdrop: Collapse of ENRC case
Ephgrave has only been in post since late 2023 and joined after a series of high-profile investigative failures and collapsed prosecutions under his predecessors. One of the most notable was the collapse of the Eurasian Natural Resources Corporation (ENRC) case, which undermined confidence in the SFO’s operational effectiveness.
Even though the SFO had accomplished lawyers and investigators on its team, the organization clearly lacked strategic judgment. It dropped its decade-long bribery and corruption investigation into the Kazakh mining firm in April 2025, following intense legal battles and accusations of mishandled evidence. The SFO was then ordered to pay more than £16.9m ($22.9m) in costs to ENRC following judicial criticism of its conduct during the investigation.
I view the failings as arising from an institutional culture that, over time, has drifted away from the fundamentals of effective investigation.
Some career detectives and investigators, especially those who have prosecuted fraud cases to the criminal burden, have a degree of empathy for the SFO. But the errors in the ENRC case were of astronomic proportions. Lengthy fraud investigations generate enormous disclosure burdens, complicated further by shifting prosecutorial theories. From the outside, it appeared that the SFO was struggling to balance prosecutorial common sense with investigative decisiveness.
That is not a criticism of the lawyers who work at the organization – I have always been at pains to point out that many are outstanding professionals. Instead, I view the failings as arising from an institutional culture that, over time, has drifted away from the fundamentals of effective investigation.
My suggestions to date have been threefold:
- disband the SFO;
- merge it into the National Crime Agency (NCA); and
- hand over the reins to an experienced senior police detective.
Major fraud investigations only succeed when they are led with investigative clarity, disciplined decision-making, and early strategic focus. These are core competencies of experienced detectives; they are also requisite traits of the lawyers overseeing such prosecutions.
Nick Ephgrave’s reforms
Against that backdrop, the appointment of Nick Ephgrave as director of the SFO in September 2023 was significant. It vindicated my long-held opinion that for the SFO to survive, it needed someone with a policing background at the helm.
In fact, Ephgrave was the first non-lawyer to lead the SFO. A career police officer, he brought with him decades of experience in major crime, counterterrorism, and organizational leadership.
Crucially, he understood investigations not as abstract legal exercises, but as operational campaigns with defined objectives, timelines, and risk profiles. This was not merely a symbolic change, but a philosophical shift.
Under Ephgrave, the SFO began to speak and act more like an investigative agency, with meaningful intelligence and case assessment. For many of us, this was long overdue.
Within his first year, Ephgrave made it clear that the SFO would be more assertive, more predictable, and more transparent with corporates and investigators alike.
Most importantly, he signaled a shift in how the SFO would engage with self-reporting companies, whistleblowers, and overseas partners. This was not just rhetoric, it was backed by revised guidance, public statements, and operational changes.
Deferred Prosecution Agreements
Despite the positivity surrounding his appointment, I had serious reservations when he embraced Deferred Prosecution Agreements (DPAs), in which organizations come to an agreement with a prosecutor (where the organization has received a criminal offence charge).
To my mind, the SFO exists to prosecute, not to barter – the clue is in the name. I understand better than anyone the need to be pragmatic, but I believe that DPAs should fall into the remit of a regulator, not a prosecutor. It’s akin to the police saying to a drug dealer: “Hand over the drugs and some money, and we’ll call it quits if you promise not to do it again.”
I believe that DPAs should fall into the remit of a regulator, not a prosecutor.
I do not like that DPAs effectively allow wealthier corporates to buy their way out of criminal liability. Why should the rich and well-resourced be able to dodge prosecution and potential prison sentences by pushing cash in the direction of a law enforcement agency? Leave that to the regulators.
I assert that DPAs are a useful regulatory tool, but they should not allow crooks to evade justice. (Of course, I understand the counterargument that they are essential in complex, crossborder cases where prosecution may be considered impractical.)
Whistleblower incentives
Another one of my pet subjects is the dire need for the UK to implement whistleblower incentives. For decades, the UK has lagged behind the United States in this area. US programs under the SEC and DOJ have paid millions to whistleblowers, generating intelligence that regulators simply would not otherwise obtain.
Ephgrave was candid about this disparity. He described the UK’s failure to incentivize whistleblowers as a “brain drain,” noting that UK-based insiders often took information to US authorities instead because of the obvious inconsistency over award amounts.
Under Ephgrave’s leadership, the SFO actively explored mechanisms to introduce whistleblower rewards, tying incentives to successful enforcement outcomes. As a detective, being able to incentivize “snouts” was the norm in the 1980s and 1990s. However, because of some high-profile police corruption cases, this became more difficult and we saw the inevitable decrease in the intelligence gleaned from informants.
For investigators, this matters enormously. High-quality insider intelligence shortens investigations, improves evidential strength, and increases conviction rates. For corporates, it fundamentally changes the risk calculus around internal misconduct.
Ephgrave’s reforms were not universally welcomed. Some former insiders and commentators criticized his approach, questioning whether a police officer should lead a prosecutorial agency.
I argued that this criticism said more about the critics than the leadership itself. From my own experience, such resistance is familiar. Cultural change is uncomfortable. But the early evidence suggested that Ephgrave’s approach was restoring confidence internally and externally.
I’ve no idea why Ephgrave has decided to hang up his boots. Has he been headhunted, or simply decided to ride off into the sunset? Whatever his reasoning, I wish him well. But progress is fragile, and leadership matters, especially where it affects organizational culture.
The question now is whether the SFO will build on what Ephgrave has achieved. For investigators, regulators, and the regulated community alike, the answer will shape the UK’s economic crime landscape for years to come. So the next step is crucial.
