Serious Fraud Office (SFO): Full Form, Powers and Cases

In short

SFO stands for Serious Fraud Office, the UK "non-ministerial department" that investigates and prosecutes serious or complex fraud, bribery and corruption in England, Wales and Northern Ireland. Its powers come from the Criminal Justice Act 1987. Since 1 September 2025 it can also prosecute a large organization that fails to prevent fraud. India's SFIO is a separate body.

In 2025 to 2026 the SFO announced five new cases, carried out seven search operations across 24 premises and arrested 14 people (SFO Annual Report and Accounts 2025 to 2026, page 3). It was also the first year of the failure to prevent fraud offense.

What is the Serious Fraud Office (SFO)?

The SFO takes a narrow slice of fraud: its framework agreement with the Attorney General's Office sets its first aim as "To investigate and prosecute the most serious or complex cases of fraud, bribery and corruption" (annual report, page 9). Section 1 of the Criminal Justice Act 1987 sets it up: "A Serious Fraud Office shall be constituted for England and Wales and Northern Ireland."

The SFO was established in 1988 and does not cover Scotland, the Isle of Man or the Channel Islands (SFO, About us). Before authorizing an investigation, the Director weighs the actual or intended harm to the public, the UK's reputation and its economy, and whether the case needs the SFO's specialist powers.

In UK police, finance, banking, government and company contexts, SFO has the same full form and meaning. The UK's anti money laundering rules and supervisors are a separate system, set out in the whitepaper AML in the United Kingdom.

How does the SFO work?

After Ultra Electronics reported suspected corruption in Algeria, the SFO opened an investigation in 2018 and in 2024 extended it to every country where the company operated. On 1 May 2026 a judge approved a deferred prosecution agreement (DPA) for failure to prevent bribery: a 10 million pound penalty plus 4.8 million pounds in costs (SFO, Ultra Electronics DPA).

Case teams of lawyers, investigators and forensic accountants run each investigation with what the annual report calls "unique powers of compulsion" (page 8). The SFO has an active caseload of around 120 and secured over 2.89 million pounds in proceeds of crime in 2025 to 2026 (pages 24 and 25).

Table 1. The SFO case process, stage by stage.

Stage What happens Legal basis or source Who acts
Referral A whistleblower, company or agency reports SFO reporting routes (Table 5) Intelligence Division
Pre investigation Section 2 powers used to decide whether to open a case CJA 1987 s2A, any case since 15 January 2024 Director
Investigation Interviews, document notices, search warrants CJA 1987 s1(3) and s2 Case team; a constable executes warrants
Outcome Prosecution, or a DPA for an organization CJA 1987 s1(5); Crime and Courts Act 2013 Schedule 17 Director; the Crown Court approves a DPA
Recovery Confiscation and civil recovery Proceeds of Crime Act 2002, via CJA 1987 s1(6A) Director; the court orders

What can a section 2 notice require?

Table 2. Section 2 powers (Criminal Justice Act 1987, s2).

Power or offense Subsection Limit or maximum
Answer questions or give information s2(2) At a set place and time, or at once
Produce documents and explain them s2(3) If missing, say where they are
Search premises s2(4) and (5) Warrant from a justice of the peace, executed by a constable
Banking records s2(10) Consent of the person owed confidence, or the Director's authorization
Privileged material s2(9) Protected; a lawyer may have to give a client's name and address
Failing to comply without reasonable excuse s2(13) On summary conviction: up to six months, a level 5 fine or both
A false or misleading statement, made knowingly or recklessly s2(14) and (15) On indictment: up to two years, a fine or both; summary: up to six months, a fine or both
Falsifying, concealing or destroying relevant documents when an investigation is known or suspected s2(16) and (17) On indictment: up to seven years, a fine or both; summary: up to six months, a fine or both

A notice can go to the person under investigation or to anyone the Director believes has relevant information.

What happens if the SFO investigates you or your company?

A section 2 interview exists "to establish facts by obtaining from the interviewee full and truthful answers" (SFO, Section 2 interviews). Those answers can be used against the interviewee only in limited cases, such as a prosecution for a false statement (s2(8)).

Take an employee interviewed about their employer. A lawyer who also acts for the employer is unlikely to be allowed in.

What does the failure to prevent fraud offense ask of a company?

Start with the Home Office's example. The head of payroll at company A diverts staff pension contributions to fund other projects inside the company. Company A could be liable unless a court decides it had reasonable procedures in place (Home Office guidance, 2.8).

That is the offense in section 199 of the Economic Crime and Corporate Transparency Act 2023: a person associated with the organization, such as an employee, agent or subsidiary, commits a fraud offense intending to benefit it.

It is a defense for the organization to prove it had "such prevention procedures as it was reasonable in all the circumstances to expect" (s199(4)). The SFO can prosecute the offense for England, Wales and Northern Ireland (guidance 2.7.1). Its investigative powers extend to Scotland, but prosecution there lies with the Crown Office and Procurator Fiscal Service (footnote 21).

Table 3. Three UK failure to prevent offenses (each extends to the whole UK).

Offense Who is caught Defense In force
Failure to prevent bribery, Bribery Act 2010 s7 A relevant commercial organization "Adequate procedures" 1 July 2011
Failure to prevent facilitation of tax evasion, Criminal Finances Act 2017 s45 A relevant body Reasonable prevention procedures 30 September 2017
Failure to prevent fraud, ECCTA 2023 s199 A large organization: two or more of turnover over £36 million, balance sheet total over £18 million, more than 250 employees in the previous financial year (s201) Reasonable prevention procedures 1 September 2025 (guidance 1.3)

The guidance sets six principles:

  • Top level commitment: leaders reject profit based on fraud.
  • Risk assessment: existing assessments of fraud and other economic crime can be extended to the frauds in scope.
  • Proportionate risk based procedures: being regulated does not "automatically qualify" a firm's procedures.
  • Due diligence: on the people who perform services for the firm.
  • Communication, including training: the policy reaches every level.
  • Monitoring and review: detection built for employee fraud against the firm may need extending to frauds that benefit it.

"Extend the AML risk assessment, do not reuse it: the failure to prevent fraud offense is about fraud your own people and agents commit to benefit the firm, and the Home Office guidance warns that procedures tailored to a different type of risk will not necessarily be an adequate response," says Ufuk Gürdaş, Compliance Specialist.

What is a deferred prosecution agreement?

A DPA lets a designated prosecutor suspend the charge against an organization while it meets agreed terms, once the Crown Court approves the deal. Schedule 17 of the Crime and Courts Act 2013 sets the rules for England and Wales, in force since 24 February 2014: designated prosecutors include the Director of Public Prosecutions and the SFO Director, an individual cannot be a party, and the terms must be "fair, reasonable and proportionate" (paragraphs 1 to 4 and 8).

Rolls-Royce's DPA of 17 January 2017 added a compliance program to its disgorgement, penalty and costs. Under the SFO's corporate cooperation guidance of 24 April 2025, a company that self reports and cooperates fully can expect an invitation to negotiate a DPA unless exceptional circumstances apply.

Which notable cases has the SFO brought?

LIBOR shows why a case list needs a date. The SFO's investigation into how some traders and submitters influenced benchmark interest rates led to nine convictions of senior bankers. On 23 July 2025 the Supreme Court found two unsafe and the SFO sought no retrial; by 9 October 2026 the Court of Appeal had overturned six more (SFO response to the Supreme Court judgment, last updated 9 October 2026).

Table 4. Notable SFO cases (SFO and court documents, read 19 October 2026).

Case Date Outcome Amount Note
Rolls-Royce 17 January 2017 DPA (Rolls-Royce judgment) £258,170,000 disgorgement, £239,082,645 penalty, £12,960,754 costs Nigeria, Indonesia, Russia, Thailand, India, China, Malaysia
Airbus 31 January 2020 DPA (Airbus judgment) €990,963,712 including costs Joint investigation with France; US Department of Justice in parallel
LIBOR and EURIBOR 23 July 2025 to 9 October 2026 (appeals) Nine convictions (two guilty pleas, seven jury verdicts); eight now unsafe or overturned None stated No retrial sought after the Supreme Court ruling
Ultra Electronics 1 May 2026 DPA, failure to prevent bribery £10 million penalty, £4.8 million costs Yearly reports to the SFO for three years

Airbus holds the larger DPA: the judge said its sanction exceeded the total paid under all earlier DPAs (Airbus judgment, paragraph 1).

How can you tell a real SFO call or email from a scam?

The SFO warns that criminals use its name by email, telephone and WhatsApp (SFO scam guidance, 12 November 2024).

  • SFO email always comes from a .gov.uk address.
  • A blurry, stretched or skewed logo on a letter is likely a scam.
  • The SFO never asks for bank details; a request for money to return cryptocurrency is a scam sign.
  • The SFO never calls from its switchboard number, and a sender who will not prove they work there is a warning sign.
  • Doubtful messages go as an attachment to alerts@sfo.gov.uk, subject "SFO Authentication Request". That address takes no fraud reports.

This is impersonation fraud; the SFO says to break contact and not reply.

How do you report fraud to the SFO?

Table 5. Where to report (SFO pages, read 19 October 2026).

You are Route What to know
An individual reporting serious fraud, bribery or corruption The SFO's secure reporting portal For serious or complex cases
A whistleblower The same portal (SFO whistleblower page) 167 disclosures from 1 April 2024 to 31 March 2025, action on 153
A company self reporting intelunit@sfo.gov.uk (corporate self report) Other material sent there is not assessed; SFO contact within 48 business hours (cooperation guidance)
A company's lawyer, before a self report GeneralCounsel@sfo.gov.uk Talks with the Director of Legal Services, open since 13 October 2026
A victim of everyday fraud Report Fraud, 0300 123 2040 (SFO notice on Report Fraud) Replaced Action Fraud on 4 December 2025

A whistleblowing consultation open until 8 January 2027 seeks views on a proposed SFO scheme of financial rewards for people who report economic crime.

How does the UK SFO differ from India's SFIO and New Zealand's SFO?

Table 6. Three bodies behind the same initials.

Body Where Legal basis Investigates Prosecutes
Serious Fraud Office (SFO) England, Wales and Northern Ireland Criminal Justice Act 1987 Serious or complex fraud, bribery and corruption Yes
Serious Fraud Investigation Office (SFIO) India, Ministry of Corporate Affairs Set up 2 July 2003; notified under Companies Act 2013 s211(1) on 21 July 2015 (SFIO history) Affairs of companies the Government assigns Prosecutes or recommends prosecution
Serious Fraud Office New Zealand Serious Fraud Office Act 1990 (SFO NZ, Legislation) Serious or complex fraud Yes, through a panel of specialist lawyers

One decision stays with a large organization's compliance lead: whether the section 199 fraud risk assessment is a document of its own or a chapter of the AML one. The guidance says extending an existing assessment may work best (3.2).

Frequently asked questions

What is the primary purpose of the SFO in relation to bribery and corruption?

Its framework agreement with the Attorney General's Office sets its first aim: to investigate and prosecute the most serious or complex cases of fraud, bribery and corruption. The SFO also recovers the proceeds of those crimes through confiscation and civil recovery under the Proceeds of Crime Act 2002.

Is the SFO the same as the SFIO in India?

No. The SFO is the UK's Serious Fraud Office, set up under the Criminal Justice Act 1987 for England, Wales and Northern Ireland. The SFIO is India's Serious Fraud Investigation Office under the Ministry of Corporate Affairs, which investigates the affairs of companies and prosecutes or recommends prosecution.

Is the SFO part of the police?

No. The SFO is a "non-ministerial department" whose own case teams of lawyers, investigators and forensic accountants both investigate and prosecute its cases. Police officers come in at the search stage, because a constable executes a search warrant issued under section 2 of the Criminal Justice Act 1987.

What does SFO stand for in finance, banking and government?

In UK finance, banking, police and government contexts, SFO stands for Serious Fraud Office, the body set up under the Criminal Justice Act 1987. A bank or company meets it through a section 2 notice, a fraud or bribery investigation, a deferred prosecution agreement or its own self report.

Does the SFO cover Scotland?

No. The SFO covers England, Wales and Northern Ireland, not Scotland, the Isle of Man or the Channel Islands. The Home Office guidance notes that its investigative powers extend to Scotland, but prosecution there lies with the Crown Office and Procurator Fiscal Service.

What counts as serious fraud for the SFO?

Before authorizing an investigation, the Director weighs the actual or intended harm to the public, the UK's reputation and its economy, and whether the case needs the SFO's specialist powers. Cases that pass are the serious or complex fraud, bribery and corruption the SFO investigates and prosecutes.
